ABSTRACT

Nas últimas décadas, o aumento das indicações para dispositivos cardíacos eletrônicos implantáveis tem sido acompanhado pela elevação dos casos de complicações relacionadas ao seu uso, dentre elas a endocardite infecciosa. Apesar dos avanços diagnósticos e terapêuticos da doença, esta mantém elevada morbimortalidade. Os casos relacionados aos dispositivos apresentam importantes limitações referentes aos critérios e aos métodos diagnósticos que implicam na tomada de decisão terapêutica sobre retirada do dispositivo, com risco de morte e outras complicações. Ainda assim, o ecocardiograma mantém um grande valor no diagnóstico da endocardite infecciosa relacionada a dispositivos cardíacos e de suas complicações. O entendimento das limitações e dos desafios acerca do diagnóstico reforça a necessidade de mais estudos sobre do tema. O presente artigo visa descrever a epidemiologia, a microbiologia, os fatores de risco, a patogenia, o diagnóstico e o tratamento da endocardite infecciosa associada aos dispositivos cardíacos eletrônicos implantáveis, visando demonstrar, principalmente, o valor dos exames de imagem na abordagem dessa condição clínica, com ênfase nos achados ao ecocardiograma.


In recent decades, the increase in indications for implantable electronic cardiac devices has been accompanied by an increase in cases of complications related to their use, including infectious endocarditis. Despite the diagnostic and therapeutic advances of the disease, it maintains high morbidity and mortality. The cases related to the devices have important limitations regarding the criteria and diagnostic methods that imply in making a therapeutic decision about removing the device, with risk of death and other complications. Still, echocardiography remains of great value in the diagnosis of infective endocarditis related to cardiac devices and their complications. Understanding the limitations and challenges regarding diagnosis reinforces the need for further studies on the topic. This article aims to describe the epidemiology, microbiology, risk factors, pathogenesis, diagnosis and treatment of infective endocarditis associated with implantable electronic cardiac devices, aiming to demonstrate, mainly, the value of imaging tests in addressing this clinical condition , with emphasis on echocardiogram findings.

ABSTRACT

En la actualidad, las tasas que se conocen de colonización de piel y mucosa por el staphylococcus aureus están incrementando día a día. Se ha encontrado una fuerte correlación de la invasión de estos en otras partes del cuerpo (zona axilar, mucosa nasal, entre otras) con la aparición de celulitis y/o abscesos faciales. Se demostró que la flora nasal es muy diversa, encontrándose patógenos como streptococcus viridans, staphylococcus aureus, staphylococcus coagulasa negativa y Corynebacterium sp, pero sin posibilidad de definir con exactitud cuál es la constancia de los mismos pudiendo presentarse variaciones de esta. A su vez, esto se ve agravado por la falta de adherencia al tratamiento por parte de los pacientes y de otras condiciones como, el mismo contagio o predisposición del medio (sudoración, altas temperaturas, mala higiene, etc.), que facilitan la capacidad de dicho microorganismo de tornarse más resistente, incrementar su población y aumentar así la patogenicidad a través de la codificación de una exotoxina llamada Pantón Valentín (SAMR). Se demostrará entonces, la metodología que se llevó a cabo a través de un análisis descriptivo transversal de los casos tratados en el Hospital Mariano y Luciano de La Vega, con el fin de correlacionar causalidad y efecto (AU)


At present, the rates known for skin and mucosa colonization by Sthapylococcus aureus are increasing day by day. A strong correlation has been found of the invasion of these in other parts of the body (axillary area, nasal mucosa, among others, being the latter the most representative), with the appearance of cellulite and/or facial abscesses. It was shown that the nasal flora is very diverse, finding pathogens such as Streptococcus Viridans, Staphylococcus aureus (S aureus), coagulase negative Staphylococcus and Corynebacterium sp, but that has not been defined exactly the constancy of the same, can be presented variations of this. In turn, this is aggravated by the lack of adherence to treatment by patients and other conditions such as the same contagion or predisposition of the medium (sweating, high temperatures, poor hygiene, etc.), which facilitate the capacity of said Microorganism to become more resistant, increase its population and thus increase the pathogenicity through the codification of a exotoxin called Valentín Panty. To prove the methodology that was carried out through a transversal descriptive analysis of the cases treated at the Mariano Hospital and Luciano de La Vega in order to fulfil the objective of correlating causality and Effect (AU)

ABSTRACT

Objetivo: Realizar uma análise estatística das internações de pacientes idosos com osteomielite, por região brasileira. Métodos: Foram pesquisadas informações de saúde disponíveis na plataforma do Departamento de Informática do Sistema Único de Saúde (DATASUS), avaliando-se, de 2012 a 2016, as variáveis: internações por osteomielite (M86 do CID-10), faixa etária acima de 60 anos, sexo e etnia. Resultados: De 78.967 pacientes internados por osteomielite no Brasil, 16.736 (21,19%) eram idosos, com a Região Sudeste registrando maior número de casos (7.163 internações; 42,79%), seguida da Nordeste (5.165; 30,86%), da Sul (2.462; 14,71%), da Centro-Oeste (1.162; 6,9%) e da Norte (784; 4,6%). O número de internações manteve-se relativamente constante, com média de 3.347 casos por ano. Pacientes de 60 a 69 anos foram os com maior registro (8.786 casos; 52,49%). Em segundo lugar, ficaram os de 70 a 79 anos (5.232; 31,2%) e, por último, os acima de 80 anos (2.718; 16,24%). Em relação ao sexo, o masculino notificou 9.232 internações (55,16%), com 7.504 (44,83%) para o feminino. A etnia branca apresentou maior número de notificações (6.117; 36,54%), principalmente nas Regiões Sudeste e Sul, seguida pela parda (4.947; 29,55%), que se destacou dentre as demais regiões. Conclusão: Diante da heterogeneidade de fatores que predispõem à osteomielite, com destaque para o diabetes mellitus, urge garantir um manejo precoce da infecção e de comorbidades causadoras, a fim de evitar complicações debilitantes ao idoso, bem como prevenir futuras recidivas e internações onerosas ao sistema de saúde brasileiro. (AU)


Objective: To perform a statistical analysis of hospitalizations of elderly patients with osteomyelitis, by Brazilian region. Methods: Health information available from the Informatics Department of the Unified Health System (DATASUS) platform was investigated, from 2012 to 2016. The following variables were assessed: admissions due to osteomyelitis (ICD-10 M86), age group over 60, gender and ethnicity. Results: Of the 78,967 patients hospitalized due to osteomyelitis in Brazil, 16,736 (21.19%) were elderly, with the Southeast Region having a higher number of cases (7,163 admissions - 42.79%), followed by the Northeast (5,165 - 30.86%), South (2,462 - 14,71%), Midwest (1,162 - 6,9%), and North (784 - 4,6%). The number of hospitalizations remained relatively constant, with an average of 3,347 cases per year. Patients aged 60 to 69 years were the ones with the highest registry (8,786 cases - 52.49%); in second place, those aged 70 to 79 years (5,232 - 31.2%) and, finally, those above 80 years old (2,718 - 16.24%). Regarding gender, males accounted for 9,232 hospitalizations (55.16%), with 7,504 (44.83%) for females. White people had the highest number of reports (6,177 - 36.54%), mainly in the Southeast and South Regions, followed by browns (4,947 - 29.55%), who were more prevalent in the other regions. Conclusion: In view of the heterogeneity of factors that predispose to osteomyelitis, especially diabetes mellitus, it is urgent that early management of the infection and causative comorbidities is ensured, in order to avoid debilitating complications for the elderly, as well as to prevent future relapses, and costly hospitalizations to the Brazilian health system.

ABSTRACT

Previous studies have reported on the phytotherapeutic potential of propolis from southern Brazil (Urupema, Santa Catarina State), in particular, its efficacy in the treatment of bovine mastitis. The present study evaluates the effect of seasonal variation on the chemical composition of propolis from southern Brazil and its resultant antimicrobial and cytotoxic activities in the context of treating bovine mastitis. Antimicrobial activity against Staphylococcus aureus was assessed, along with the cytotoxicity and induction of apoptosis in MAC-T bovine mammary epithelial cells. With the exception of spring propolis, the flavonoid quercetin was the main compound present in all samples. The minimum inhibitory concentration (MIC) of propolis against S. aureus from mastitic milk was 140 µg/mL for samples collected during the spring, autumn, and winter seasons, but 280 µg/mL for samples collected in summer. For MAC-T cells, the spring propolis extract was more toxic with an IC50 of 120 µg/mL. However, for 120 µg/mL of spring propolis extract, only 0.77% of necrotic and 37% of apoptotic MAC-T cells were found, respectively. Nonetheless, the induction of cell death through apoptosis by propolis extract suggests less severe damage to bovine mammary glands. Moreover, only negligible seasonal variation was found in the chemical composition of propolis from southern Brazil, and no biological activities were determined to be harmful. Therefore, this propolis shows promise as an alternative to commercial antimicrobials in the control of bovine mastitis, offering support for organic milk production.(AU)


Estudos prévios tem demonstrado o potencial terapêutico da propolis do Sul do Brasil (Urupema, Santa Catarina), em particular no tratamento da mastite bovina. O presente estudo tem como objetivo avaliar o efeito da variação sazonal sobre a composição química da própolis de Urupema do Sul do Brasil e suas atividades antimicrobiana e citotóxica visando o tratamento da mastite bovina. A atividade antimicrobiana contra Staphylococcus aureus foi avaliada, juntamente com a citotoxicidade e indução de apoptose em células epiteliais mamárias bovina da linhagem MAC-T. Com exceção da própolis da primavera, o flavonóide quercetina foi o composto majoritário em todas as amostras. A concentração inibitória mínima (CIM) da propolis contra S. aureus de leite mastítico foi 140 µg/mL para as amostras de primavera, outono e inverno e 280 µg/mL para a amostra coletada no verão. Para as células MAC-T, o extrato de própolis da primavera foi o mais tóxico, sendo a IC50 120 µg/mL. Entretanto, com 120 µg/mL do extrato de própolis primaveril, somente 0,77% de células MAC-T necróticas e 37% apoptóticas foram encontradas. Portanto, a indução da morte celular por apoptose pelo extrato de própolis sugere danos possivelmente menos graves a glândula mamária bovina. Além disso, somente uma pequena variação sazonal foi encontrada para a composição química da propolis do Sul do Brasil, a qual não prejudicou suas atividades biológicas. Portanto, esta própolis mostra como uma alternativa promissora ao uso de antimicrobianos comerciais no controle da mastite bovina e uma opção para subsidiar a produção orgânica de leite.Palavras-chave: Células MAC-T.

ABSTRACT

ABSTRACT Background: The rate of methicillin-resistant Staphylococcus aureus (MRSA) among the total of S. aureus isolates decreased to 35.3% in 2017 in China. It is unclear whether the molecular characteristics of S. aureus isolates have changed as the rate decreased. Objective: This study aimed to investigate the molecular characteristics and virulence genes profile of S. aureus isolates causing bloodstream infection and analyze the correlation between the prevalence rates of the common sequence types and MRSA. Methods: A total of 112 S. aureus strains from eight hospitals of four cities, including 32 MRSA isolates, were identified and evaluated through multilocus sequence typing, spa typing, and determination of virulence genes. Results: Twenty-five STs were identified, of which ST5 (21.4%) was the most prevalent, whereas the prevalence of ST239 correlated with the rate of MRSA among all S. aureus isolates. Forty-six spa types were identified, of which t2460 (14.3%) was the most common. clfa, hla, seb, fnbA and hlb were the prevailing virulence genes. 81.3% MRSA and 45.0% methicillin-sensitive S. aureus (MSSA) isolates harbored six or more tested virulence genes. ST5-t2460, seldom noted in bloodborne S. aureus isolates in China, was the most common clone. The prevalence of harboring six or more virulence genes in ST5-t2460 and ST188-t189 were 93.8% and 8.3%, respectively. Conclusion: ST5-t2460 was the most common clone in S. aureus causing bloodstream infection followed by ST188-t189, which had never been noted in China before. Moreover, ST5-t2460 harbored more virulence genes than ST188-t189, and the prevalence of ST239 clone decreased with the proportion of MRSA among all S. aureus isolates.

ABSTRACT

Introducción: las enfermedades transmitidas por alimentos son una problemática mundial a la que la Organización Mundial de la Salud y los países brindan una atención especial. Dentro de los grupos de alto riesgo se encuentran los productos de origen animal, como la leche y sus derivados. Staphylococcus aureus es un microorganismo causante de brotes de las enfermedades transmitidas por alimentos, lo que genera la necesidad de estudiar la carga microbiana y establecer los controles adecuados. Objetivo: evaluar la calidad microbiológica en el proceso manufacturero en el área de producción de la Cooperativa de Producción Agropecuaria Chone LTDA, con el fin de asegurar la ausencia del Staphylococcus aureus en el queso fresco 100% chonero. Materiales y métodos: Se realizó un estudio de evaluación de la calidad en cuatro fases. Se realizaron exámenes microbiológicos iniciales, se identificaron las causas esenciales de contaminación identificadas por observación directa, revisión de documentos y entrevistas, como base para la elaboración e implementación de POE (Procedimientos Operativos Estandarizados) y POES (Procedimientos Operativos Estandarizados de Saneamiento). Se cumplieron los requerimientos éticos y se realizaron los análisis estadísticos utilizando porcentaje e índices como medida resumen y con el uso de IBM SPSS, versión libre, realizándose regresión logística binaria para determinar la probabilidad de éxito al aplicar dichos procedimientos. Resultados: los análisis microbiológicos iniciales (antes de implementación de POE y POES), dieron como resultado: 98, 116, 79, 120 y 13 UFC/g para las muestras: DiQ1, DiQ2, DiQ3, DiQ4 y DiQ5, respectivamente. Las causas esenciales de contaminación fueron falta de control microbiológico, falta de control del aspecto del personal y falta de control del agua) Una vez implementados los POE y POES, el análisis mostró ausencia en todas las muestras analizadas. Conclusiones: se concluye que la aplicación de POE y POES tiene un efecto significativo sobre la ausencia del Staphylococcus aureus, con probabilidad de éxito del 100% (AU).


Introduction: Diseases transmitted by foodstuffs (DTF) are a worldwide problem that receives special attention by WHO and different countries. High risk groups include foodstuff of animal origin, like milk and its by-products. Staphylococcus aureus is a microorganism responsible for DTF outbreaks which generates the necessity of studying its microbial burden and establishing the adequate controls. Objective: to evaluate the microbiological quality of the manufacturing process in the production area of the Farming and Stockbreeding Cooperative Chone LTDA, to assure the absence of Staphylococcus aureus in the manufacturing process of fresh cheese. Materials and methods: A study to assess the quality in four stages was carried out: initial microbiological tests, identification of the essential contamination causes by direct observation, documental review and inquires. They were used to elaborate and implement the Standardized Operational Procedures (SOP) and the Standardized Operational Procedures of Sanitation (SOPS). The ethical requirements were fulfilled and the statistical tests were performed using percentages and indexes as summary measures through IBM SPSS, free version; binary logistic regression was made to determine the success when applying those procedures. Results: initial microbiological controls (before implementing SOP and SOPS) gave these results 98, 116, 79, 120, and 13 UFC/g for samples DiQ1, DiQ2, DiQ3, DiQ4 and DiQ5 respectively. The main contamination causes were lack of microbiological control, lack of control on the staff's cleanliness and lack of control on the water. After implementing SOP and SOPS microbiological control found particularly clean samples. Conclusions: SOP and SOPS have a significant effect on the amount of Staphylococcus aureus, with 100% success probability (AU).

ABSTRACT

La formación de biofilms es un importante factor de virulencia que contribuye en la cronicidad de los procesos infecciosos producidos por Staphylococcus aureus. Las proteínas presentes en su superficie pueden promover la formación de biofilm. En este estudio se comparó la distribución de genes que codifican para proteínas de adhesión asociadas con la formación de biofilm en cepas resistentes (MRSA) y sensibles a meticilina (MSSA). Al analizar un total de 106 aislados obtenidos de muestras sólidas y líquidas recuperados de un hospital de México, se determinó que la formación de biofilm está asociada de manera significativa a cepas MRSA (83%). Mediante la reacción en cadena de la polimerasa (PCR), se buscó la presencia de nueve genes de adhesinas (eno, ebps, fnbA, fnbB, fib, clfA, clfB, bbp, y cna) y dos de regulación del biofilm (icaA, icaD). Los resultados mostraron que los genes icaA, icaD, eno, ebps, clfA, clfB se amplificaron en todas las cepas mientras que los genes fnbA, fnbB, fib, y bbp tuvieron una distribución variable. Los datos obtenidos muestran por primera vez que la presencia del gen cna se encuentra asociada a cepas MSSA y no productoras de biofilm (p<0,05).


Biofilm formation is an important virulence factor that contributes to the chronicity of the infectious processes caused by Staphylococcus aureus. The proteins on the surface of this bacterium can promote the formation of a biofilm. The distribution of genes encoding adhesion proteins associated with biofilm formation in methicillin-sensitive (MSSA) and methicillin-resistant (MRSA) strains was compared in this study. The analysis of a total of 106 isolates obtained from solid and liquid samples collected from a hospital in Mexico showed that biofilm formation was significantly associated with MRSA strains (83%). The presence of nine adhesine genes (eno, ebps, fnbA, fnbB, fib, clfA, clfB, bbp, cna) and two biofilm regulatory genes (icaA, icaD) was looked for by polymerase chain reaction (PCR). The results evidenced that icaA, icaD, eno, ebps, clfA, and clfB genes were amplified from all strains, while fnbA, fnbB, fib, and bbp genes were non-uniformly distributed among them. Notably, the results showed for the first time that the presence of the cna gene is associated with biofilm non-producing MSSA strains (p<0.05).

A análise de um total de 106 isolados obtidos a partir de amostras sólidas e líquidas coletadas em um hospital no México mostrou que a formação de biofilme é associada significativamente a cepas MRSA (83%). A técnica de reação em cadeia da polimerase (PCR) foi utilizada para verificar a presença de nove genes de adesinas (eno, ebps, fnbA, fnbB, fib, clfA, clfB, bbp, cna) e dois genes reguladores do biofilme (icaA, icaD). Os resultados mostraram que os genes icaA, icaD, eno, ebps, clfA, clfB foram amplificados em todas as cepas, enquanto que os genes fnbA, fnbB, fib, e bbp tiveram uma distribuição variável. Os dados obtidos mostram pela primeira vez que a presença do gene cna está associada a cepas MSSA e não produtoras de biofilme (p<0,05).

ABSTRACT

Objetivo: Buscou-se no presente trabalho identificar os principais patógenos envolvidos em infecções em pacientes queimados, bem como enfatizar a relevância do diagnóstico adequado para o tratamento de sepse. Método: Para a realização do presente trabalho, foi feito levantamento bibliográfico de caráter exploratório e obtidos 33 estudos relevantes. A coleta de informações ocorreu nos meses de março a novembro de 2016. Resultados: Dentre os principais patógenos presentes em queimados, que podem gerar quadro de sepse, estão Pseudomonas aeruginosa, Staphylococcus aureus, Acinetobacter sp, Candida albicans e Proteus sp. Esses podem, ou não, estar relacionados à própria microbiota do paciente. O processo de infecção, com perda da primeira linha de defesa imunológica, deixa o organismo suscetível à entrada e instalação de microrganismos. O tratamento da sepse depende de fatores relevantes, que incluem a gravidade da lesão e o agente causador da infecção. Conclusão: O risco de ocorrência de sepse, associada às infecções em queimados nas unidades de tratamento intensivo, pode ser reduzido com o diagnóstico adequado e acompanhamento do paciente.


Objective: This article aimed to identify the main pathogens involved in infections in burned patients, as well as to emphasize the relevance of the appropriate diagnosis for the treatment of sepsis. Methods: For the accomplishment of the present work, it was carried out a bibliographic survey of exploratory character and 33 relevant studies were obtained. Data collection was carried out from March to November 2016. Results: Among the main pathogens present in burnt patient related with sepsis are Pseudomonas aeruginosa, Staphylococcus aureus, Acinetobacter sp, Candida albicans and Proteus sp. These pathogens may or may not be related to the patients microbiota. The infection process, with loss of the first line of immune defense, leaves the organism susceptible to the entry and installation of microorganisms. Treatment of sepsis depends on relevant factors including the severity of the lesion and the agent of the infection. Conclusion: The risk associated with sepsis in burned patients may be reduced with appropriate diagnosis and monitoring.

ABSTRACT

ABSTRACT A better understanding of the antimicrobial susceptibility, carriage of virulence determinants and molecular characteristics of Staphylococcus aureus isolates associated with skin and soft tissue infections (SSTIs) may provide further insights related to clinical outcomes with these infections. From January 2012 to September 2013, a total of 128 non-duplicateS. aureus isolates were recovered from patients with SSTIs. All 128 S. aureus SSTI isolates carried at least five virulence genes tested. Virulence genes detected among at least 70% of all tested isolates included hld (100%), hla (95.3%),icaA (96.9%), clf (99.2%),sdrC (79.7%), sdrD (70.3%), andsdrE (72.7%). The prevalence of MRSA isolates with 10 virulence genes tested (54.4%, 31/56) was significantly higher than that among MSSA isolates (35.2%, 25/71) (p < 0.05). The positive rates of seb, sen, sem, sdrE and pvl among MRSA isolates were significantly higher than among MSSA isolates (p< 0.05). ST7 and ST630 accounting for 10.9% were found to be the predominant STs. The most prevalent spa type was t091 (8.6%). MRSA-ST59-SCCmec IV was the most common clone (12.3%) among MRSA isolates whereas among MSSA isolates the dominant clone was MSSA-ST7 (15.5%). Six main clonal complexes (CCs) were found, including CC5 (52.3%), CC7 (11.7%), CC59 (8.6%), CC88 (6.3%), CC398 (4.7%), and CC121 (3.1%). A higher carriage of seb and sec was found among CC59 isolates. In comparison to CC5 and CC7 isolates, those with the highest carriage rates (>80.0%) of sdrC and sdrD, CC59 isolates had lower prevalence of these two virulence genes. All CC59 isolates were susceptible to gentamicin and trimethoprim/sulfamethoxazole, while CC5 and CC7 isolates had resistance rates to these two antimicrobials of 25.4% and 20.9%, and 40.0% and 40.0%, respectively. The resistance rates for tetracycline, clindamycin, and erythromycin among CC5 isolates were lower than among CC7 and CC59 isolates. In conclusion, the molecular typing of S. aureusSSTI isolates in the present study showed considerable heterogeneity. ST7 and ST630 became prevailing clones. Different S. aureus clones causing SSTIs were associated with specific antimicrobial resistance and virulence gene profiles.

ABSTRACT

Enterotoxigenic Staphylococcus aureus strains that were isolated from foods were investigated for their ability to develop direct-tolerance and cross-tolerance to sodium chloride (NaCl), potassium chloride (KCl), lactic acid (LA) and acetic acid (AA) after habituation in sublethal amounts (1/2 of the minimum inhibitory concentration - 1/2 MIC and 1/4 of the minimum inhibitory concentration - 1/4 MIC) of Origanum vulgare L. essential oil (OVEO). The habituation of S. aureus to 1/2 MIC and 1/4 MIC of OVEO did not induce direct-tolerance or cross-tolerance in the tested strains, as assessed by modulation of MIC values. Otherwise, exposing the strains to OVEO at sublethal concentrations maintained or increased the sensitivity of the cells to the tested stressing agents because the MIC values of OVEO, NaCl, KCl, LA and AA against the cells that were previously habituated to OVEO remained the same or decreased when compared with non-habituated cells. These data indicate that OVEO does not have an inductive effect on the acquisition of direct-tolerance or cross-tolerance in the tested enterotoxigenic strains of S. aureus to antimicrobial agents that are typically used in food preservation.

ABSTRACT

O camu-camu (Myrciaria dubia Mc. Vaugh) tem demonstrado ser um fruto promissor devido ao potencial funcional, principalmente pelo alto teor de vitamina C e compostos fenólicos, em especial elagitaninos. Este trabalho teve como objetivo avaliar os efeitos sobre os compostos fenólicos dos processos de secagem de polpa comercial de camu-camu, por leito de jorro e atomização (spray-drying), em diferentes temperaturas e concentrações de agentes carreadores, comparando-os com os do processo de liofilização. Os pós obtidos foram comparados em relação ao teor total de compostos fenólicos, ácido ascórbico e proantocianidinas. Além disso, avaliou-se o potencial benéfico à saúde através da determinação da capacidade antioxidante in vitro , atividade antimicrobiana e inibição das enzimas α-amilase, α-glicosidase e enzima conversora da angiotensina (ECA). Avaliou-se também proteção e regeneração celulares em modelo de planárias (Dugesia trigrina). Complementarmente, os pós de camu-camu foram adicionados em leite de soja, que foram fermentados com bactérias produtoras de ácido láctico (L. helveticus ATCC 12046 e L. plantarum NCDO 1193), para verificar sua funcionalidade quando incorporados como ingredientes em alimentos funcionais. Os resultados mostraram que a secagem da polpa acarretou em perdas significativas de compostos bioativos, na ordem ácido ascórbico>fenólicos totais> proantocianidinas, e spray-drying>leito de jorro>liofilização. Os compostos fenólicos detectados nos pós de camu-camu foram elagitaninos, ácido elágico, derivados de quercetina, ácido siríngico e miricetina, por LC-TOF-MS. A liofilização foi a melhor técnica de secagem para a preservação dos compostos fenólicos, e também da capacidade antioxidante e de inibição enzimática. Além disso, os pós liofilizados e atomizado (contendo 6% goma arábica a 120 °C) foram mais efetivos contra Staphylococcus aureus que a ampicilina. Os extratos desses pós demostraram potencial para proteção celular e rejuvenescimento no modelo de planárias. E por último, o leite de soja enriquecido com o pó de camu-camu resultou em um produto com maior teor de fenólicos, alta capacidade antioxidante e propriedades anti-hiperglicêmica e anti-hipertensiva. Portanto, os pós de camu-camu são ricos em compostos fenólicos e tem potencial para serem acrescentados como ingredientes em alimentos para o controle dos estágios iniciais de diabetes tipo 2 e complicações associadas


Camu-camu (Myrciaria dubia Mc. Vaugh) has demonstrated promising perspectives as a functional food, mainly due to high vitamin C and phenolic compounds contents, in particular ellagitannins. This study aimed to evaluate the effect of different drying processes (spouted bed drying, spray-drying) at selected temperatures and carrier concentrations, comparing to freeze-drying, on the contents and composition of phenolic compounds. The pulp powders were compared in relation to phenolic profiles, ascorbic acid and proanthocyanidins contents. Further, functional health potential was evaluated such as in vitro antioxidant capacity, antimicrobial activity and inhibition of α-amylase, α-glucosidase and angiotensin converting enzyme (ACE). It was also investigated cellular protection and regeneration in planaria (Dugesia trigrina) model. Additionally, camu-camu powders were added into soymilk and were fermented by lactic acid bacteria (L. helveticus ATCC 12046 and L. plantarum NCDO 1193) to verify their functionality as a functional food ingredient. The results showed that drying of the pulp led to significant losses of bioactive compounds, in the order ascorbic acid>total phenolics>proanthocyanidins, and spray-drying>spouted bed drying>freeze-drying. Phenolic compounds, such as ellagitannins, ellagic acid, quercetin derivatives, syringic acid and myricetin were detected in camu-camu by LC-TOF-MS. The freeze-drying was the best technique to preserve phenolic compounds, and also antioxidant capacity and enzyme inhibition. Besides that, freeze-dried and spray-dried (6% arabic gum at 120 °C) powders were more effective against Staphylococcus aureus than ampicillin. The extracts of those powders have desmonstrated potential to cellular protection and rejuvenation in planaria model. Finally, soymilk enriched with camu-camu powders resulted in more phenolic contents, high antioxidant capacity and anti-hyperglycemia and anti-hipertension properties product. To sum up, camu-camu powder is rich in phenolic bioactive profiles has potential as part of dietary strategies in the management of early stages of type 2 diabetes and associated complications

ABSTRACT

Background: Staphylococcus aureus [S.aureus] is a common virulent pathogen in diabetic foot infections. Infection of diabetic foot ulcer [DFU] is a major cause for impaired healing and leads to osteomyelitis, bacteraemia and sepsis. Treatment failure of DFU may ultimately lead to limb amputation


Objectives: This work was carried out to clarify the role of S.aureus as a causative agent of diabetic foot infection, and characterize the antibiotic resistance pattern, virulence factors implicated in the pathogenicity of S. aureus and the accessory gene regulator as a global regulator of virulence determinant production


Methodology: This study was carried out on 111 patients admitted to diabetic foot clinic [MUH] having infected diabetic foot ulcer. Grading of infection was assessed. The collected specimens were cultivated on 5% sheep blood agar and mannitol salt agar. Isolates were identified as S. aureus by being catalase positive, mannitol fermenter, DNase positive and coagulase positive. Virulence was characterized by thermonuclease test, slime production, hemagglutination test, and biofilm formation. Multiplex PCR was used for detection of agr groups


Results: S.aureus represented 32% of total pathogens isolated. 58.3% of S.aureus strains were slime producers. 70.8% were biofilm producers. The most prevalent agr type was agr 1 and represented 54.2% followed by agr 2 [29.2%], agr 3 [8.3%], and agr 4 [4.2%]


Conclusion: S. aureus is the most common cause of diabetic foot infection at our locality. Slime and biofilm producing strains are more resistant to antibiotics than non producers. S. aureus infection is more common among grade 2 and 3 ulcers. This data is crucial for selection of appropriate antibiotic therapy. agr type 1 is the most prevalent type in DFU at our locality

ABSTRACT

Staphylococcal enterotoxins can act as allergens and stimulate production of specific IgE with subsequent development of allergic manifestations. In addition, they act as superantigens that induce cytokine secretion with more increase of IL-4/IFN-gamma ratio causing augmentation of allergic reactions. Herein we tested the hypothesis that exposure to Staphylococccus aureus and its enterotoxins induces immunological changes that contribute to the pathogenesis of allergic rhinitis and bronchial asthma. This study included 45 air way allergic patients, and 45 controls. The following were done: intradermal allergy skin testing, invitro effect of staphylococcal enterotoxin B [SEB] on cytokine secretion from separated peripheral blood mononuclear cells, detection of nasal carriage of S. aureus and its enterotoxin production by ELISA and serum levels of total IgE, SEB-specific IgE and eosinophil cationic protein [ECP] were measured. We found that nasal carriage of enterotoxin producing S. aureus in allergic patients was significantly higher than in control. Blood eosinophilia, total IgEand ECP levels were significantly higher in S. aureus nasal carrier than non-carrier patients. On in vitro exposure of PBMCs to [SEB], IFN-gamma secretion was significantly less in patients than control and IL-4 secretion was significantly more in patients than control. SEB-specific IgE was detected in 15.6% of patients and not detected in control. There was a significant positive correlation between SEB-specific IgE level in patients and markers of severity of allergic reaction including blood eosinophilia, ECP and total IgE level. This study suggests that nasal carriage of enterotoxin producing S. aureus has a potential role in the development and severity of allergic airway diseases

ABSTRACT

To determine the current sensitivity pattern against staphylococci found in skin and soft tissue infections. Patients were enrolled from OPD of Dermatology Department, PNS Shifa Hospital, Karachi. All the patients with skin infections showing growth of Staphylococcus aureus on culture medium were selected. After informed consent, swab specimens were collected under aseptic measures from skin lesions for microbial analysis and sensitivity pattern. Among skin infections, furunculosis was found most common, comprising of 45.7% [n=43], cellulitis 15.0% [n=14], ecthyma 8.5% [n=8], erysipelas 8.5% [n=8] and impetigo 22.3% [n=21]. According to drug sensitivity patterns, vancomycin was found sensitive in 100%, linezolid 98.9%, mupirocin 96.8%, rifampicin 95.7%, chloramphenicol 94.7%, clindamycin 86.2%, amikacin 84%, moxifloxacin 83%, fusidic acid 79.8%, gentamicin 76.6%, oxacillin 69.1%, ciprofloxacin 68.1%, amoxicillin-clavulanic acid 62.8%, erythromycin 60.6% and trimethoprimsulphamethaxazole 57.4% of cases Vancomycin, linezolid, rifampicin, clindamycin, moxifloxacin and chloramphenicol showed highest efficacy in this study. However, clinical studies are required to confirm in vivo efficacy and side effect profile of these drugs
