Percentage Incidences of Bacteria in Mahseer (Tor putitora), Silver carp (Hypophthalmichthys molitrix) Fish Collected from Hatcheries and Local Markets of District Malakand and Peshawar of Khyber Pakhtunkhwa, Pakistan

Abstract Fish is the main source of animal protein for human diet. The aim of this study was to find out prevalence of pathogenic bacteria of two selected economically important fish of Pakistan namely Mahseer (Tor putitora) and Silver carp (Hypophthalmichthys molitrix). Live fish samples from hatcheries and dead fish samples from different markets of study area were randomly collected. The fish samples were analyzed for isolation, identification and prevalence of bacteria. The isolated bacteria from study fish were identified through biochemical test and about 10 species of pathogenic bacteria were identified including the pathogenic bacteria to human and fish namely, Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus iniae, Serratia spp. Citrobacter spp. Stenotrophomonas spp. Bacillus spp. and Salmonella spp. The bacterial percentage frequency of occurrence in Silver carp and Mahseer fish showed Pseudomonas aeruginosa 21.42%, Staphylococcus epidermidis 17.85%, Escherichia coli 11.90%, Staphylococcus aureus 9.52%, Citrobacter spp. 9.52%, Serratia spp. 8.33%, Streptococcus iniae 7.14%, Stenotrophomonas spp. 5.95%, Bacillus spp. 4.76% and Salmonella spp. 3.57%. The study revealed that Fish samples of Mahseer and Silver carp that were collected from markets have found more isolates (10 bacterial species) than did the fresh fish pond samples (03 bacterial species) of hatcheries. The occurrence of pathogenic bacteria in study fish showed risk factor for public health consumers.

Marcadores bioquímicos propuestos para el estudio de la sarcopenia / Proposed biochemical markers for the study of sarcopenia

La sarcopenia asociada a la edad es una condición clínica caracterizada por una disminución en la fuerza, calidad y cantidad de masa muscular así como también en la función muscular. Un biomarcador se define como una característica que es medible objetivamente y evaluable como indicador de un proceso biológico normal, patológico o respuesta terapéutica a una intervención farmacológica. Los marcadores bioquímicos propuestos para el estudio de la sarcopenia pueden ser categorizados en dos grupos. El primero de ellos evalúa el estatus musculoesquelético; este panel de marcadores está formado por miostatina/folistatina, procolágeno aminoterminal tipo III e índice de sarcopenia. El segundo grupo de marcadores bioquímicos evalúa factores causales, para lo cual se sugiere medir el factor de crecimiento insulino-símil tipo 1 (IGF-1), dehidroepiandrosterona (DHEAS), cortisol, facto-res inflamatorios [proteína C reactiva (PCR), interleuquina 6 (IL-6) y factor de necrosis tu-moral (TNF-a)]. Las recomendaciones realiza-das están basadas en la evidencia científica disponible en la actualidad y la disponibilidad de la metodología apropiada para cada uno de los biomarcadores. (AU)

Sarcopenia is a progressive and generalized skeletal muscle disorder defined by decrease in the strength, quality and quantity of muscle mass as well as in muscle function. A biomarker is defined as a feature objectively measured and evaluated as an indicator of a normal biologic process, a pathogenic process or a pharmacologic response to therapeutic intervention. The biochemical markers proposed for the study of sarcopenia may be classified in two groups. The first group evaluates the musculoskeletal status, made up by myostatin/follistatin, N-terminal Type III Procollagen and the sarcopenia index. The second evaluates causal factors, where the measurement of the following is suggested: hormones insulin-like growth factor-1 (IGF-I), dehydroepiandrosterone sulphate (DHEAS), cortisol, inflammatory factors [C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-a (TNF-a)]. The recommendations made are based on scientific evidence currently available and the appropriate methodology availability for each biomarker. (AU)

Synergetic Influence of Some Tropical Leaf Meals and Garlic on the Haemato-biochemical Parameters and Antioxidant Activities of Weaner Pigs

Aim: This experiment was designed to study the effects of using garlic-composite leaf meals produced from four (4) different leaves and garlic: bitter leaf (Vernonia amygdalina), scent leaf (Ocimum gatissimum), Neem leaf (Azadirachta indica), Moringa leaf (Moringa oleifera) and Garlic (Allium sativum) as a premix in the diets of growing pigs. The leaves and garlic were air dried, milled and sieved separately. Thereafter the leaves and garlic were mixed in the ratio of 4 (Vernonia amygdalina): 3 (Moringa oleifera): 1 (Ocimum gatissimum): 1 (Azadirachta indica) and 1 (Allium sativum) to produce the garlic-composite tropical leaf meals. Individual leaves and their composite mix were analyzed for proximate, mineral, antioxidant and the phytochemical components of the leaves were determined using GCMS and other standard methods. Methodology: Eighteen large white weaner-pigs of eight weeks were allocated in a completely randomized design for this experiment comprising three treatments and three replicates with two pigs per replicate. The average weight of the pigs were 13 kg. Basal diet were formulated and subdivided into three portions in which garlic-composite leaf meals were fed at 0g/kg, 10g/kg, and 20g/kg were used as an additives to the diets of weaner pigs and the diets were designated as I, II and III respectively. The pigs were then assigned to these 3 dietary treatments which were fed to the pigs at 5% of their body weight for 12 weeks experimental period. Water was supplied ad libitum throughout the experimental period. All data were subjected to analysis of variance. Results: Dietary inclusion of GCLM on haematology, serum biochemistry indices and antioxidants significantly (P<0.05) affected the Packed Cell Volume (%), Mean Corpuscular Volume (fl) Lymphocytes (%), Granulocytes (%), Alanine aminotransferase (IU/L), Aspartate aminotransferase (IU/L), Total Protein (g/l) and catalase (Ku) of the experimental pigs. Conclusions: It could be concluded within the limit of this study, that garlic-composite leaf meals had high nutrient potentials for pigs and could completely help growing pigs to improve in body weight as the composite leaf meals increases in pig diets.

Control Efficacy of Jingdusha against Corynespora cassiicola (Hyphomycetales: Dematiaceae) on Cucumber

Aims: The paper aimed to clarify the effect of cucumber target leaf spot (TLS) under the Jingdusha (JDS) treatment. Study Design: We applied the method of artificial inoculation in the pot, and analyzed the changes in growth indexes and physiological characteristics. Place and Duration of Study: In 2018, these experiments were conducted in College of Bioscience and Biotechnology of Shenyang Agricultural University (Lab 240). Methodology: The seedlings in the two-leaf period were induced by the best application scheme of JDS, then inoculated Corynespora cassiicola for 24 h. Cucumber seedlings of each treatment group were randomly selected for photographing and growth index determination after inoculation for 5 d. The leaves of cucumber seedlings in each treatment group were randomly collected at 1 d, 3 d, 5 d, 7 d, and 9 d after inoculation for the determination of physiological and biochemical indicators. Results: When C. cassiicola infects cucumber, JDS can effectively improve the growth and photosynthetic pigment content of cucumber, reduce the degradation of chlorophyll (Chl) under the stress of C. cassiicola, strengthen the variety of metabolic responses in the plant, repair the enzyme protection system of cucumber leaves, reduce the accumulation of reactive oxygen species, shorten the process of membrane lipid peroxidation in blades. Conclusion: Taken together, these results suggest that JDS can improve the resistance of cucumber seedlings to C. cassiicola by regulating growth indexes and physiological characteristics. This work will provide a theoretical basis for further elucidating the molecular mechanism of JDS in cucumber defense against C. cassiicola.

Longitudinal study of the body mass index and biochemical nutritional parameters of patients in dialysis / Estudio longitudinal del índice de masa corporal y parámetros bioquímicos nutricionales en pacientes en diálisis

ABSTRACT Background/Aim: Chronic kidney failure is frequently related to malnutrition. This research aimed to assess the nutritional status of hemodialysis patients by assessing their biochemical and anthropometric parameters and determining whether the disorders suffered stemmed from nutritional deterioration directly related to time on dialysis. Materials and Methods: This research monitored 90 patients of both genders with chronic kidney failure who regularly received hemodialysis at the kidney unit of our Hospital in Granada (Spain) over five years. The patient's blood was tested quarterly for plasma albumin (Alb), total cholesterol (TC), and total proteins (TP) and monthly for transferrin (Tr). Anthropometric measurements were taken of the patient's weight, height, and body mass index (BMI) and, based on the patient's BMI, classified as established by the World Health Organization. Results: During the five years of our study, patients experienced a statistically significant decrease in total protein (0.941g/dl), plasma albumin (0.9382g/dl), total cholesterol (23.77mg/dl), and transferrin (78.17. g/dl) p < 0.0001. On the contrary, the mean BMI values did not show statistically relevant differences (p < 0.805). However, all patients remained in the WHO category of overweight. The body volume values did not show statistically significant differences either. Conclusions: In conclusion, the nutritional deterioration of these patients was not reflected in their BMI but mainly in their serum chemistry.

RESUMEN Antecedentes/Objetivo: La insuficiencia renal crónica está relacionada frecuentemente con la malnutrición, afectando aproximadamente a un tercio de los pacientes con enfermedad renal avanzada, lo que contribuye a su morbilidad y mortalidad. El objetivo de esta investigación fue evaluar el estado nutricional de los pacientes en hemodiálisis valorando sus parámetros bioquímicos y antropométricos y determinar si los trastornos que padecían se debían al deterioro nutricional directamente relacionado con el tiempo en diálisis. Materiales y Métodos: Es esta investigación realizó un seguimiento de 90 pacientes de ambos sexos con insuficiencia renal crónica, que recibían hemodiálisis periódicamente en la unidad renal de nuestro Hospital en Granada (España) durante un período de cinco años. La sangre de los pacientes se analizó trimestralmente para albúmina plasmática (Alb), colesterol total (TC) y proteínas totales (TP), y mensualmente para transferrina (Tr). Se tomaron medidas antropométricas de peso, talla e índice de masa corporal (IMC) de los pacientes y se les efectuaron mediciones antropométricas de peso, altura e índice de masa corporal calculado mediante la formula peso/talla², y agrupada según la clasificación de la OMS en IMC < 18.50 infrapeso, 18.50 a 24,99 normal, 25 a 29,99 sobrepeso y >30 del IMC s/OMS y se consideró para el estudio como desnutrición un en IMC < 23 kg/m2 y niveles de albumina <3,8 g/dl según el consenso del panel de expertos de la International Society for Renal Nutrition and Metabolism. Resultados: Durante los cinco años de nuestro estudio, los pacientes experimentaron una disminución estadísticamente significativa de proteínas totales (0,941 g/dl), albúmina plasmática (0,9382 g/dl), colesterol total (23,77 mg/dl) y transferrina (78,17. g /dl) p < 0,0001. Por el contrario, los valores medios del IMC no mostraron diferencias estadísticamente relevantes (p < 0,805). Sin embargo, todos los pacientes permanecieron en la categoría de sobrepeso de la OMS. Los valores de volumen corporal tampoco mostraron diferencias estadísticamente significativas. Conclusiones: La desnutrición de los pacientes en diálisis es un hecho patente, el IMC no se corresponde con los parámetros bioquímicos observados, por lo que el deterioro nutricional de estos pacientes se manifiesta principalmente mediante los parámetros bioquímicos estudiados.

Osmoregulatory Appraisal of Some Osmoprotectants on Hydrolytic Activities of Some Enzymes on Seeds of Two Water Stressed Cultivars of Sorghum bicolor (Moench)

Enzymes play significant roles in metabolic processes of seeds. Therefore, this study evaluated osmoregulatory potential of some osmoprotectants on activities of some hydrolytic enzymes in the seeds of two cultivars (SOSAT.C-88 and CV. LCIC 9702) of sorghum bicolor. Matured seeds of the two cultivars were harvested and prepared for alpha, beta, total amylase and proteinase activities assay. The osmoprotectants produced significant variations on the enzymes at 10 and 14 days (DA) of 8 weeks after treatments (WAT). Seeds of well-watered SOSAT.C-88 produced higher alpha (2.10 IU/ml), beta (1.70 IU/ml) and total amylase activities (3.30 IU/ml) at 14 days (DA). Higher alpha (2.01 IU/ml and total amylase activities (2.61 IU/ml) were recorded in the seeds of CV. LCIC 9702 well-watered at 14 days DA 8WAT. Furthermore, total amylase activities (3.87 IU/ml) were recorded in the seeds produced by CV. LCIC 9702 well-watered at 14 days DA. Significant increase was noticed in beta (1.14 IU/ml) and alpha amylase (1.58 IU/ml) in the seeds of CV. LCIC 9702 treated with mycorrhiza. CV. LCIC 9702 well watered produced highest proteinase activities (1.57 U/ml) while least of the parameters were recorded in SOSAT.C-88 and CV. LCIC 9702 droughted. In conclusion, the osmoprotectants had regulatory effects on the activities of hydrolytic enzymes therefore the use of the osmoprotectants in farming should be encouraged.

Testes bioquímicos para identificação de leveduras na medicina veterinária - revisão de literatura / Biochemical tests to yeast identification in veterinary medicine - literature review / Pruebas bioquímicas para identificación de levaduras en la medicina veterinaria - revisión de literatura

As leveduras são fungos de importância à medicina veterinária por causarem doenças infecciosas em diferentes hospedeiros animais. A presente revisão de literatura teve como objetivo relatar os principais testes bioquímicos capazes de auxiliar na identificação de fungos leveduriformes de interesse veterinário e zoonótico. Para o levantamento bibliográfico, foram consideradas 48 publicações científicas selecionadas na área e indexadas nas principais bases de dados, entre os anos de 1988 e 2020. Como resultados, observou-se que oito provas são as mais empregadas na rotina micológica. Devido à baixa variabilidade morfológica das espécies leveduriformes, testes bioquímicos complementares são fundamentais na rotina laboratorial. A análise do perfil bioquímico de leveduras contribui na determinação taxonômica dos fungos a partir de reações químicas, visto que o metabolismo varia de acordo com a espécie, resultando em metabólitos distintos, os quais podem ser avaliados por diferentes provas. Conclui-se que a identificação fenotípica das leveduras é imprescindível no diagnóstico, prognóstico, tratamento e controle de doenças fúngicas e contribui para a manutenção da saúde animal.(AU)

Yeasts are fungi of importance to veterinary medicine because they cause infectious diseases in different animal hosts. This literature review aimed to report the main biochemical tests capable of assisting in the identification of yeast-like fungi of veterinary and zoonotic interest. For the bibliographical survey, 48 selected scientific publications in the area and indexed in the main databases, between the years 1988 and 2020, were considered. As a result, it was observed that eight tests are the most used in the mycological routine. Due to the low morphological variability of yeast species, complementary biochemical tests are fundamental in the laboratory routine. The analysis of the biochemical profile of yeast contributes to the taxonomic determination of fungi based on chemical reactions, since the metabolism varies according to the species, resulting in different metabolites, which can be evaluated by different tests. It is concluded that the phenotypic identification of yeasts is essential in the diagnosis, prognosis, treatment and control of fungal diseases and contributes to the maintenance of animal health.(AU)

Correlation between blood biochemical parameters and choroidal thickness in patients with nonproliferative diabetic retinopathy / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To investigate the relationship between blood biochemical parameters and choroidal thickness(CT)in na&#x0026;#xEF;ve-treatment of patients with nonproliferative diabetic retinopathy(NPDR).METHODS: Prospective cross-sectional study. A total of 92 patients(92 eyes)with na&#x0026;#xEF;ve-treated NPDR were selected in the Affiliated Eye Hospital of Nanchang University from July 2021 to July 2022. All of the patients included in this study were subjected to ophthalmologic examination including enhanced depth imaging optical coherence tomography(EDI-OCT), best corrected visual acuity(BCVA), fundus fluorescence angiography, intraocular pressure, slit lamp and fundus examination. At the same time, they were also underwent hematological examination including blood glucose, glycosylated hemoglobin(HbA1c), serum creatinine, uric acid, urea, β2 microglobulin, high density lipoprotein(HDL), low density lipoprotein(LDL), serum calcium, serum potassium and other tests. According to the glomerular filtration rate(eGFR)and CT, the patients were divided into normal, mild and moderate to severe renal function group, pachychoroid group and the leptochoroid group. The blood biochemical indexes, CT differences and theirs correlation were analyzed in na&#x0026;#xEF;ve-treated NPDR patients.RESULTS: A total of 92 cases(92 eyes)were included in this study, with 51 males(51 eyes), 41 females(41 eyes), 45 right eyes and 47 left eyes. There was no significant difference in age, axial length and disease duration among the three groups(all P&#x003E;0.05). There were significant differences in nasal 0.5, 1.5mm, subfoveal and temporal 0.5, 1.5mm CT among three groups(all P&#x003C;0.05). There was no statistical significance in age, axial length and the course of disease between the pachychoroid and leptochoroid groups(all P&#x003E;0.05). There were significant differences in creatinine, eGFR, uric acid, urea, potassium and β2-microglobulin between the pachychoroid group and the leptochoroid group(all P&#x003C;0.05). There were no significant differences in total cholesterol, triglyceride, HDL, LDL, HbA1c, serum calcium and glucose between the two groups(all P&#x003E;0.05). CT was negatively correlated with creatinine, urea, uric acid and β2-microglobulin, and positively correlated with eGFR. Multiple regression analysis showed that the thicker the nasal 0.5mm CT, the higher the eGFR(B=0.292, P&#x003C;0.001). CT affected creatinine, eGFR, urea, uric acid and β2-microglobulin(B=16.5, 64.6, 24.1, 18.1, 20.3; P=0.008, &#x003C;0.001, &#x003C;0.001, 0.004, 0.001), while there were no significant effects on total cholesterol, triglyceride, glucose, serum calcium, HDL and LDL(all P&#x003E;0.05).CONCLUSION: In patients with na&#x0026;#xEF;ve-treated NPDR, the thicker the CT, the better the renal function. The decrease of CT in newly diagnosed NPDR patients is an important hint to pay attention to the renal function.

The MAP and heart rate T 1 to T 4 in PCV group were significantly lower than those in VCV group, and there was statistical difference ( P<0.01 or <0.05). The base excess, serum natrium, serum potassium and pH T 1 to T 4 in PCV group were significantly higher than those in VCV group, while the blood glucose was significantly lower than that in VCV group, and there was statistical difference ( P<0.01 or <0.05). Conclusions:Compared with VCV, PCV can promote the recovery of respiratory mechanics index, stabilize hemodynamics and improve biochemical metabolism index in patients undergoing laparoscopic colorectal cancer surgery.

The correlation of bone metabolism biomarkers in newborn twins and their pregnant mothers / 中国新生儿科杂志

Objective:To study the correlation of bone metabolism biomarkers between newborn twins and their mothers during pregnancy.Methods:From January 1, 2018 to June 30, 2022, newborn twins with mild symptoms admitted to the neonatal department of our hospital were retrospectively reviewed. The clinical data of the twins and their mothers were collected, including bone metabolism biomarkers of the twins within 3 d after birth and their mothers within last month during pregnancy. The twins were assigned into different groups according to gestational age(GA), birth weight(BW), the relationship between BW and GA(appropriate for GA(AGA),small for GA(SGA) and large for GA(LGA), birth season, gender, and the mothers' age, ethnicity, pre-delivery body mass index (BMI), gestational BMI increase, number of births and chorionic properties. The correlations of bone metabolism biomarkers between the twins and their mothers were analyzed.Results:A total of 302 pairs of twins were included. The incidence of insufficient or deficient serum 25-(OH)D 3 was 97.4% among the mothers, and 87.7% among the twins. The levels of blood phosphorus ( r=0.262, P<0.001) and 25-(OH)D 3 ( r=0.239, P=0.002) in mothers were positively correlated with the twin with larger BW. No significant differences existed in 25-(OH)D 3 between genders, AGA,SGA and LGA, birth season, and mothers' age, ethnicity, pre-delivery BMI, gestational BMI increase and chorionic properties( P>0.05). 25-(OH)D 3 in the twins were positively correlated with BW and 25-(OH)D 3 of mothers before delivery ( P<0.05) and negatively correlated with number of births ( P<0.05). Conclusions:In most mothers and their newborn twins, 25-(OH)D 3 are insufficient or deficient. The levels of blood phosphorus and 25-(OH) D 3 are correlated between the newborns and their mothers. The lower the BW of the newborn, the more times the mother give birth and the lower the mother's pre-delivery 25-(OH)D 3 level, the lower the newborn's 25-(OH)D 3 level.

Correlation analysis and benchmark dose study on bone metabolic biochemical index of low doses of exposed hydrogen fluoride workers / 中华劳动卫生职业病杂志

Objective: To analyze correlation of occupational hydrogen fluoride exposure to low doses of bone metabolism index through occupational epidemiological investigation and benchmark dose calculation. Methods: In May 2021, using cluster sampling method, 237 workers exposed to hydrogen fluoride in a company were selected as the contact group, and 83 workers not exposed to hydrogen fluoride in an electronics production company were selected as the control group. The external exposure dose and urinary fluoride concentration, blood and urine biochemical indicators of the workers was measured.The relationship between external dose and internal dose of hydrogen fluoride was analyzed. The external dose, urinary fluoride was used as exposure biomarkers, while serum osteocalcin (BGP), serum alkaline phosphatase (AKP) and urinary hydroxyproline (HYP) were used as effect biomarkers for bone metabolism of hydrogen fluoride exposure. The benchmark dose calculation software (BMDS1.3.2) was used to calculate benchmark dose (BMD) . Results: Urine fluoride concentration in the contact group was correlated with creatinine-adjusted urine fluoride concentration (r=0.69, P=0.001). There was no significant correlation between the external dose of hydrogen fluoride and urine fluoride in the contact group (r=0.03, P=0.132). The concentrations of urine fluoride in the contact group and the control group were (0.81±0.61) and (0.45±0.14) mg/L, respectively, and the difference between the two groups was statistically significant (t=5.01, P=0.025). Using BGP, AKP and HYP as effect indexes, the urinary BMDL-05 values were 1.28, 1.47 and 1.08 mg/L, respectively. Conclusion: Urinary fluoride can sensitively reflect the changes in the effect indexes of biochemical indexes of bone metabolism. BGP and HYP can be used as early sensitive effect indexes of occupational hydrogen fluoride exposure.

Animal experimental study on the effects of different levels of amputation on cardiovascular system / 生物医学工程学杂志

Vascular injury resulting from lower limb amputation leads to the redistribution of blood flow and changes in vascular terminal resistance, which can affect the cardiovascular system. However, there was no clear understanding of how different amputation levels affect the cardiovascular system in animal experiments. Therefore, this study established two animal models of above-knee amputation (AKA) and below-knee amputation (BKA) to explore the effects of different amputation levels on the cardiovascular system through blood and histopathological examinations. The results showed that amputation caused pathological changes in the cardiovascular system of animals, including endothelial injury, inflammation, and angiosclerosis. The degree of cardiovascular injury was higher in the AKA group than in the BKA group. This study sheds light on the internal mechanisms of amputation's impact on the cardiovascular system. Based on the amputation level of patients, the findings recommend more comprehensive and targeted monitoring after surgery and necessary interventions to prevent cardiovascular diseases.

Effects of liquid extract from Plinia cauliflora fruits residues on Chinese hamsters biochemical parameters / Efeitos do extrato líquido de resíduos de frutos de Plinia cauliflora sobre os parâmetros bioquímicos de hamsters chineses

Plinia cauliflora (Mart.) Kausel, popularly known as jabuticaba, is rich in polyphenols. Phenolic compounds exhibit several biological properties, which reflect on biomarkers such as biochemical parameters. In the present study, we evaluated the plasmatic levels of glucose, total cholesterol, HDL-cholesterol, triglycerides, and uric acid of Chinese hamsters fed for 45 days with a regular diet or cholesterol-enriched diet supplemented with a liquid extract obtained from P. cauliflora fruits residues standardized in ellagic acid and total phenolic compounds. The results showed that the concentrated extract obtained from jabuticaba residues increased the glycemia of animals fed with a regular diet and reduced the plasmatic uric acid levels of animals fed with a cholesterol-enriched diet. Since hyperuricemia is considered to be a significant risk factor of metabolic disorders and the principal pathological basis of gout, the liquid extract from P. cauliflora fruits residues would be a promising candidate as a novel hypouricaemic agent for further investigation.

Plinia cauliflora (Mart.) Kausel, popularmente conhecida como jabuticaba, é rica em polifenois. Os compostos fenólicos apresentam diversas propriedades biológicas, que refletem em biomarcadores, como os parâmetros bioquímicos. No presente estudo, avaliamos os níveis plasmáticos de glicose, colesterol total, HDL-colesterol, triglicerídeos e ácido úrico em hamsters chineses alimentados por 45 dias com dieta regular ou dieta enriquecida com colesterol suplementada com extrato líquido obtido de resíduos de frutos de P. cauliflora padronizado em ácido elágico e compostos fenólicos totais. Os resultados mostraram que o extrato concentrado obtido dos resíduos de jabuticaba aumentou a glicemia dos animais alimentados com dieta regular e reduziu os níveis plasmáticos de ácido úrico dos animais alimentados com dieta rica em colesterol. Uma vez que a hiperuricemia é considerada um fator de risco significativo de distúrbios metabólicos e a principal base patológica da gota, o extrato líquido dos resíduos de frutas de P. cauliflora seria um candidato promissor como um novo agente hipouricêmico para investigação posterior.

Isolation and characterization of bacteria residing in the oral, gut, and fecal samples of different pheasant species / Isolamento e caracterização de bactérias residentes nas amostras orais, intestinais e fecais de diferentes espécies de faisão

There is a paucity of research conducted on microbial prevalence in pheasants. The microbiota of captive birds has zoonotic significance and must be characterize. Present study is therefore planned to assess the microbiota from oral, fecal and gut content of captive avian species. It will be helpful in characterization of harmful microbes. Different samples taken from oral, gut and feces of ring-necked pheasants (Phasianus colchicus), green pheasants (Phasianus versicolor), golden pheasant (Chrysolophus pictus) and silver pheasant (Lophura nycthemera). Samples were collected, diluted, and inoculated onto different agar plates (MacConkey, SS agar, MSA and nutrient agar) for cultivation of bacterial species. Colonies of E.coli, Staphylococcus spp. Brachyspira spp. and Campylobacter spp were observed based on colony morphology. Colony forming unit showed E. coli as frequently found bacteria in fecal, oral and gut contents of all the above pheasants. The overall significance difference was found among bacterial species of golden pheasants, green pheasant, ring-necked pheasant, and silver pheasants. It was concluded that E.coli is predominant isolated from heathy pheasants followed by Campylobacter, Staphylococcus and Brachyspira.

Há uma escassez de pesquisas realizadas sobre a prevalência microbiana em faisões. A microbiota de aves em cativeiro tem significado zoonótico e deve ser caracterizada. O presente estudo está, portanto, planejado para avaliar a microbiota do conteúdo oral, fecal e intestinal de espécies aviárias em cativeiro. Será útil na caracterização de micróbios nocivos. Diferentes amostras retiradas da boca, intestino e fezes de faisões de pescoço redondo (Phasianus colchicus), faisões verdes (Phasianus versicolor), faisões dourados (Chrysolophus pictus) e faisão prateado (Lophura nycthemera). As amostras foram coletadas, diluídas e inoculadas em diferentes placas de ágar (MacConkey, ágar SS, MSA e ágar nutriente) para o cultivo de espécies bacterianas. Colônias de E. coli, Staphylococcus spp., Brachyspira spp. e Campylobacter spp foram observados com base na morfologia da colônia. A unidade formadora de colônia mostrou E. coli como bactéria frequentemente encontrada no conteúdo fecal, oral e intestinal de todos os faisões acima. A diferença de significância geral foi encontrada entre as espécies bacterianas de faisões dourados, faisões verdes, faisões de pescoço anelado e faisões prateados. Verificou-se que a E.coli é predominantemente isolada de faisões saudáveis, seguida por Campylobacter, Staphylococcus e Brachyspira.
