Mucormycosis in a Typhoid Treated Patient: A Case Report with Review of Literature

Introduction: Mucormycosis is an opportunistic fungal infection which is a rapidly progressing disease, and often fatal. Various predisposing factors including uncontrolled diabetes mellitus, immunosuppression, and prolonged use of steroids influence the disease pathology. Case Presentation: In this article, we present a case of mucormycosis of the palate in a patient treated with prolonged dose of steroids for typhoid fever which led to the appearance of exposed maxillary bone, and subsequent histopathological examination showed mucor hyphae. The treatment included antifungal therapy of Amphoterecine B. Management: Treatment of typhoid fever with corticosteroids, leading to immunosuppression, may result in patients harbouring opportunistic infections. An insight into the changes of oral cavity caused by corticosteroids is necessary for better diagnosis of the disease and improved patient care. In addition, early diagnosis is critical in the treatment of patients with mucormycosis

In Silico Investigation of Phytochemicals against Typhoid: A Review

Typhoid fever is a serious bacterial infection caused by Salmonella enterica serovar Typhi, and is a major public health issue in developing countries. The emergence of multidrug-resistant strains of S. Typhi has raised concerns about the effectiveness of existing treatments and has prompted the exploration of alternative therapies. Phytochemicals, which are bioactive compounds found in plants, have been investigated as potential sources of new antibacterial agents against typhoid. In this review, we conducted an in silico investigation of phytochemicals and their potential activity against S. Typhi. Our review examined current literature on phytochemicals and their antibacterial activity against S. Typhi. Using molecular docking studies, we investigated the potential binding of these phytochemicals to the target protein, DNA gyrase, which is an important drug target in S. Typhi. Our results indicate that several phytochemicals exhibit promising binding affinities to DNA gyrase, suggesting their potential as effective antibacterial agents against typhoid. Overall, our findings highlight the potential of phytochemicals as a source of new therapeutics for typhoid fever, particularly in regions where multidrug-resistant strains of S. Typhi are prevalent. The in silico approach used in this review provides a valuable tool for screening and identifying potential candidates for further investigation. Further studies are needed to validate the results of in silico studies and to explore the potential of phytochemicals as antibacterial agents against typhoid.

DIAGNOSTIC DILEMMA IN TYPHOID ENCEPHALOPATHY

Using the immune system to its advantage, Salmonella Typhi initially invades the gut followed by the reticuloendothelial system and finally the nervous system, involvement of which usually occurs around the second week of fever. In developing countries, delayed diagnosis is predominantly due to hesitation in seeking treatment. Our subject presented with fever since one week, altered mentation, headache and neck pain; she was diagnosed with enteric fever. Although her neurological abnormality could be a complication of the infection, it appeared when she became afebrile- hence we evaluated her for autoimmune conditions. Positive results hinted at autoimmune encephalitis triggered by the infection; further studies were inconclusive. Association of enteric fever with autoimmune encephalitis has not been reported. Three months later, presence of antinuclear antibodies (ANA) was rechecked- a negative report led to a retrospective diagnosis of transient ANA positivity in a nonautoimmune inflammatory disease, the case in point being enteric fever.

La batalla decisiva contra la fiebre tifoidea en Santiago de Chile en el siglo XX

Hasta 1983, cuando alcanzaba la increíble tasa de 118 casos por 100.000 habitantes, la fiebre tifoidea era la peor amenaza infecciosa en Santiago, Chile, ciudad que figuraba junto a Ciudad de México, El Cairo y Bombay, como una de las con mayor endemia en el mundo. El Ministerio de Salud respondió formando el Comité de Tifoidea de Chile, con participación de expertos nacionales y del grupo de Myron Levine, de la Universidad de Maryland, que llevó a cabo ingeniosas investigaciones, culpando al río Mapocho, cuyas aguas contaminadas con Salmonella typhi regaban los predios agrícolas vecinos, conformando así un ciclo largo de infección. Las vacunas antitíficas ensayadas (oral Ty21a atenuada y polisacárido capsular Vi inyectable) no mostraron eficacia, los portadores crónicos no se trataron, pero una campaña sanitaria a través de la televisión contribuyó decisivamente a mejorar los hábitos higiénicos de la población, fortalecida por el pánico que causó la llegada del cólera en 1991, y la fiebre tifoidea prácticamente desapareció del escenario.

Until 1983, when reached the incredible frequency of 118 cases for 100.000 habitants, typhoid fever was the worst infectious threat in Santiago, Chile, city that appeared next to Mexico City, Cairo and Bombay, as one of the most endemic in the world. The Ministry of Health responded with the creation of The Chilean Typhoid Committee, with the participation of national experts and Myron Levine's group, which carried out ingenious investigations blaming the Mapocho River, whose waters contaminated with Salmonella typhi irrigated the neighboring farms, thus conforming a long cycle of infection. Typhoid vaccines tested (strain Ty 21a oral and Vi capsular polysaccharide) did not show efficacy, chronic carriers were not treated, but a health campaign on television made a decisive contribution to improving hygiene habits of the population, strengthened by the panic caused by the arrival of cholera in 1991, and typhoid fever practically disappeared from the stage.

Clinical features of an outbreak of extensive drug resistant typhoid fever / 中华传染病杂志

Objective:To analyze the clinical features of an outbreak of extensive drug resistant typhoid fever, and to provide experience for the diagnosis and treatment of drug resistant typhoid fever.Methods:Seven patients with confirmed diagnosis of extensive drug resistant typhoid fever who visited Beijing You′an Hospital, Capital Medical University, from January 27 to February 15, 2022 were included. The clinical characteristics, drug sensitivity tests, consultation and treatment history and prognosis of the patients were analyzed through descriptive study.Results:Of the seven extensive drug resistant typhoid fever patients, three were male and four were female, one of whom was pregnant (at 32-week gestation), aged (29.8±6.8) years, with a range of 22 to 42 years. There were seven cases with fever, and the course of fever ranged from six to 20 days. There were five cases with diarrhea and lack of typhoid-specific manifestations such as rose spot, apathetic facial expression and relatively slow pulse. Four cases were complicated with intestinal bleeding and six cases developed liver function injury. Six cases had loss or decrease in eosinophil ratio and two cases had decreased white blood cell count. The results of drug susceptibility tests showed that seven strains of Salmonella typhi were resistant to chloramphenicol, ampicillin, sulfamethoxazole-trimethoprim, quinolones, ceftriaxone, cefepime, ceftazidime, cefuroxime, and sensitive to carbapenem antibiotics, tigecycline and piperacillin/tazobactam. All seven cases had a history of antimicrobial use before admission. One case was administered with intravenous ceftizoxime for seven days after admission. After discharge, cefixime was administered orally for seven days. Six patients were given intravenous piperacillin sodium/tazobactam sodium for 14 days. All blood/fecal cultures were negative and the patients were cured and discharged. During the follow-up, one patient developed splenic abscess. All the seven patients were residents of the same apartment in Beijing City, and there were water cuts and turbid odors in the incubation period, which were considered as typhoid fever outbreak caused by waterborne transmission. Conclusions:With the use of antimicrobial agents, the typical clinical manifestations of typhoid fever are absent, and the drug resistance rates to quinolone and third-generation cephalosporins increase. Appropriate antimicrobial agents should be selected and the anti-infection course should be prolonged.

Fiebre tifoidea: una etiología poco frecuente de síndrome febril prolongado en pediatría / Typhoid fever: a rare etiology of prolonged febrile illness in pediatrics / Febre tifoide: uma etiología rara de síndrome febril prolongada em pediatría

Introducción: Las infecciones representan la etiología más frecuente del síndrome febril prolongado (SFP). Si bien las fiebres entéricas constituyen una causa posible, en Uruguay su prevalencia ha disminuido significativamente con la mejora de las condiciones socio sanitarias. Objetivo: Comunicar el caso de un adolescente con una etiología actualmente excepcional de SFP. Caso clínico 14 años, sano, zona suburbana. Comienza 2 semanas previo al ingreso con dolor en hemiabdomen superior. Agrega cefalea holocraneana leve y vómitos ocasionales. 5 días previos al ingreso fiebre 40°C axilar, un pico diario, sin otra sintomatología. Tránsito digestivo bajo y urinario normal. Examen físico: lúcido, buen aspecto general, abdomen doloroso a la palpación profunda en epigastrio. Sin irritación peritoneal. Resto normal. Analítica: Leucocitos 5200mm3, Proteína C reactiva 71.4mg/dL, hemocultivo sin desarrollo. Ecografía abdominal, radiografía de tórax y ecocardiograma normales. Serologías para Virus Epstein Barr, Citomegalovirus, y Bartonella henselae negativas. Orina normal, urocultivo sin desarrollo. Persiste con fiebre, agrega exantema macropapular evanescente en tronco, sin otros síntomas. Al 7° día de internación nuevo hemocultivo: Salmonella Typhi sensible a ampicilina que recibe por 14 días. Buena evolución. Discusión: La fiebre tifoidea es una enfermedad infectocontagiosa, aguda, potencialmente mortal. Las condiciones socioeconómicas son determinantes en su transmisión. La sensibilidad del hemocultivo es mayor durante la primera semana de enfermedad, por lo que en ocasiones es necesario reiterarlo. Sus manifestaciones clínicas inespecíficas y la baja incidencia hacen que esta etiología no sea habitualmente sospechada en nuestro medio. Por tanto, es importante aumentar el índice de sospecha y considerar entre los diagnósticos diferenciales de SFP esta etiología.

Introduction: Infections are the most frequent etiology of prolonged febrile illness (PFI). Although enteric fevers are a possible cause, their prevalence has significantly diminished in Uruguay, due to improved socio-sanitary conditions. Objective: To communicate the case of an adolescent with a currently exceptional etiology of PFI. Clinical case: 14 years old, healthy, suburban area. Two days prior to admission the patient has pain in upper hemi abdomen. Adds mild holocranial headache and occasional vomiting. 5 days prior to admission axilary temperature of 40°C, one daily peak, without other symptoms. Normal lower digestive and urinary transit. Physical examination: lucid, good general aspect, pain at deep palpation in epigastrium. No peritoneal irritation. Rest is normal. Laboratory: leukocytes 5200 mm3, C-reactive protein 71.4mg/dL, blood culture shows no growth. Abdominal sonogram, thoracic X-ray and echocardiogram are normal. Negative serology for Epstein Barr Virus, Cytomegalovirus and Bartonella henselae. Normal urine, urine culture with no growth. Fever persists, adds evanescent macropapular exanthema in on the trunk, without other symptoms. On the 7th day in hospital a new blood culture shows Salmonella Typhi sensitive to ampicillin, which he receives for 14 days. Good evolution. Discussion: Typhoid fever is an acute, life-threatening, infectious disease. Socioeconomic conditions are determinant in its transmission. Blood culture sensitivity is greater during the first week of the disease, that is why it must occasionally be repeated. Its unspecific clinical manifestations and low incidence make this etiology not be usually suspected in our surroundings. It is therefore important to increase our suspicion and to consider it amongst differential diagnosis in PFI.

Introdução: As infecções representam a etiologia mais frequente da síndrome febril prolongada (SFP). Embora as febres entéricas sejam uma causa possível, no Uruguai sua prevalência diminuiu significativamente com a melhoria das condições sociossanitárias.

Adiciona dor de cabeça holocraniana leve e vômitos ocasionais. 5 dias antes da admissão febre 40°C axilar, pico diário, sem outros sintomas. Trânsito digestivo inferior e trânsito urinário normais. Exame físico: lúcido, bom aspecto geral, abdome doloroso à palpação profunda no epigástrio. Sem irritação peritoneal. Resto normal. Análise: Leucócitos 5200mm3, proteína C reativa 71,4mg/dL, hemocultura sem desenvolvimento. Ultrassonografia abdominal, radiografia de tórax e ecocardiograma foram normais. As sorologias para vírus Epstein Barr, Citomegalovírus e Bartonella henselae foram negativas. Urina normal, urocultura sem desenvolvimento. Persiste com febre, acrescenta erupção macropapular evanescente no tronco, sem outros sintomas. No 7º dia de internação, nova hemocultura: Salmonella Typhi sensível à ampicilina, que recebeu por 14 dias. Boa evolução. Discussão: A febre tifóide é uma doença infecciosa aguda, potencialmente fatal. As condições socioeconômicas são decisivas na sua transmissão. A sensibilidade da hemocultura é maior durante a primeira semana da doença, por isso às vezes é necessário repeti-la. Suas manifestações clínicas inespecíficas e baixa incidência fazem com que essa etiologia não seja usualmente suspeitada em nosso meio. Portanto, é importante aumentar o índice de suspeição e considerar essa etiologia entre os diagnósticos diferenciais da SFP.

Isolation of Fluoroquinolones Resistant Salmonella spp. from Stool Samples of Patients Attending General Hospital Minna and Ibrahim Badamasi Babangida Specialist Hospital, Minna, Nigeria

Typhoid fever continues to be a major health problem despite the use of antibiotics and the development of newer antibacterial drugs. This study aim was to isolate fluoroquinolones resistant Salmonella spp from stool samples of informed and consenting patient attending General Hospital and Ibrahim Badamasi Babangida Specialist Hospital in Minna Niger State Nigeria. A total 450 stool samples were collected from the Hospital. The results showed that 69 (30.4%) of the sample collected were positive for Salmonella species. On the basis of age children within the age range of 0-10 recorded the highest prevalence of 22.7% followed by age range 51-60 having the prevalence of 19.4%, age range >60 had the prevalence of 16.7% and age range 21-30 and 11-20 had a similar prevalence of (10.1% and 10.3% respectively) while age range 31-40 had the least prevalence of 7.8%. There were 69 isolates of Salmonella species Identified, 65(94.2%) were Resistant to the antibiotics used. The highest resistance was shown to Pefloxacin 62 (89.9%) and the lowest was shown to Ciprofloxacin 27 (39.1%). Salmonella species exhibited 52 antibiotic resistant patterns for the ten antibiotics tested with multiple antibiotic resistance index (MARI) ranging from 0.3-1.0. Molecular analysis was carried out on 5 representative isolates to identify their strains. Polymerase chain reaction (PCR) assay showed the identified Salmonella strains were Salmonella enterica subsp. arizonae strain ATCC 13314, Salmonella enterica subsp. enterica serovar Typhi strain 2018K-0756, Salmonella bongori strain SL18, Salmonella bongori strain GH3Rp and Salmonella enterica subsp. arizonae strain ATCC 13314, they all showed resistance to fluoroquinolones.

In vitro Antisalmonella and Antioxidant Activity of Hydroethanolic and Aqueous Extracts of Bauhinia rufescens Leaf and Stem Bark Extracts

In Chad, enteric fever remains a major public health problem where it is still endemic due to the precariousness of life hygiene combined with the abusive and inappropriate use of antibiotics. Objective: The aim of this work was to evaluate the in vitro antisalmonella and antioxidant activity of extracts from the leaves and stem bark of B. rufescens. Methods: Phytochemical screening of these extracts was performed by standard methods to justify the observed activities. The antisalmonella activity was evaluated using the liquid microdilution method. Antioxidant activity of these extracts was determined by investigating their 1, 1-diphenyl-2 picrylhydrazyl (DPPH?) antiradical and iron reducing capacities. Results: The Minimum Inhibitory Concentrations (MICs) were varied from 256 to 1024 µg/ml. The 95% hydroethanolic extract of the leaves exhibited higher DPPH? antiradical activity than all extracts and IC50s ? 20 ?g/ml for all extracts tested. Conclusion: These results showed that the 95% hydroethanolic extract of B. rufescens leaves possess in vitro antisalmonella and antioxidant activities and could be used for in vivo antisalmonella and antioxidant studies.

Climate and Disease Vulnerability Analysis in Blocks of Kalahandi District of Odisha, India

Background: Diarrhea and typhoid, ancient water?borne diseases which are highly connected to rainfall are serious public health challenges in the blocks of Kalahandi district of Odisha, India. Objectives: Corroboration of rainfall and waterborne diseases are available in abundance; therefore, the objective of this article is to calculate the climate and disease vulnerability index (CDVI) value for each block of Kalahandi. Methods: We have applied the livelihood vulnerability index with some modifications and classify the three major categories, i.e., exposure, sensitivity, and adaptive capacity into six subcategories. These six subcategories are further divided into 26 vulnerability indicators based on a detailed literature review. Results: The result indicated that the Thuamul Rampur block, the southernmost part of the district is highly exposed to the annual and seasonal mean rainfall, and the Madanpur Rampur block lies in the northernmost part of the district is highly exposed to diarrhea and typhoid. Based on the calculation of the final CDVI value, nearly 50% of blocks of the Kalahandi district fall in the category of very high to high vulnerable zones. Furthermore, it has been observed that factors such as rainfall and disease distribution, vulnerable population and infrastructure, and education and health?care capacities had a notable influence on vulnerability. Conclusion: It is rare to find a health vulnerability?related study in India at this microlevel based on the suitable indicators selected for a tribal and backward region.

Optimizing factors for the efficient expression and purification of spao and lamb from Salmonella typhi

We optimized the expression and purification of outer membrane proteins SpaO and LamB from Salmonella typhi. We investigated various factors in the expression and purification processes, including the use of isopropyl ß-d-1 thiogalactopyranoside (IPTG), imidazole, and urea. First, PCR amplification was carried out on SpaO and LamB genes. The genes were then cloned in pTZ57R/T, and then expressed in pET28a vector and transformed into Escherichia coli BL21 (DE3). Gene insertion was confirmed by enzymatic digestion with NdeI and XhoI. Inclusion bodies expressing recombinant SpaO and LamB were induced with 200 and 400 µL 0.5 mM IPTG, respectively. The formed protein inclusion bodies were then isolated from the pellet and solubilized in IB buffer containing 8 M urea for SpaO and 6 M urea for LamB. Proteins were refolded by dialysis in 3M urea. Purified proteins with nickel-nitrilotriacetic acid affinity chromatography and eluted with buffer containing 250 mM imidazole for SpaO and 150 mM imidazole for LamB. The protein expression profiles were analyzed by SDS-PAGE, which identified the 33 and 49 kDa bands corresponding to rSpaO and rLamB. Western blotting Purification was carried out by nickel affinity resin with 250 mM and 150 mM imidazole for rSpaO and rLamB and refolded through stepwise dialysis with anti-His tag antibodies confirmed their expression. These optimized methods can be used to generate recombinant proteins for the development of future vaccines.

Molecular characterization of the severe falciparum malaria with typhoid co-infection A case report

Malaria and typhoid co-infections can be a serious public health issue in tropical countries leading to incorrect diagnosis due to overlapping clinical presentations of malaria and typhoid and hence, causing a delay in implementing the appropriate treatment regimen for these concurrent infections. This study reports a case of six-year-old female child co-infected with severe malaria (Plasmodium falciparum) and typhoid (Salmonella typhi) diagnosed by rapid malaria antigen test (RMAT) and blood culture respectively. Further, analysis of the chloroquine resistance gene Pfcrt for the falciparum demonstrated the presence of K76T mutant allele in pfcrt gene with high IC50 (150nM) for chloroquine (CQ) drug. The present case highlights the significance of timely identification and treatment of co-infections and also provides information about the circulating P. falciparum clinical strains.

Investigation of Salmonella spp. in free-range chickens (Gallus gallus domesticus) in Southern Rio Grande do Sul / Pesquisa de Salmonella spp. em galinhas coloniais (Gallus gallus domesticus) no sul do Rio Grande do Sul

Salmonelose é uma doença causada por bactérias do gênero Salmonella, com importância para saúde pública e animal. Dentre os sorotipos hospedeiro-específicos, destaca-se o Gallinarum, que possui os biovares Gallinarum e Pullorum adaptados às aves e amplamente difundidos pelo mundo. Os dados sobre a ocorrência de Salmonella spp. em criações avícolas alternativas no Brasil são escassos. O objetivo deste estudo foi pesquisar a ocorrência de Salmonella spp. em galinhas coloniais encaminhadas para necropsia ao LRD/FV/UFPel. Foram realizadas análises histopatológicas, microbiológicas e moleculares das colônias bacterianas isoladas de 12 amostras de órgãos de galinhas domésticas dos municípios de Pelotas e Piratini, no Rio Grande do Sul. Na análise microbiológica, foram isoladas bactérias do gênero Salmonella sorotipo Gallinarum das 12 amostras, sendo 10/12 bioquimicamente compatíveis com biovar Gallinarum e 2/12 com biovar Pullorum. Na análise molecular PCR 11/12, 91,7% foram identificadas genotipicamente como Salmonella spp. O presente estudo demonstrou uma elevada frequência de isolamento de Salmonella Gallinarum biovar Gallinarum em aves sintomáticas criadas em regime extensivo. Além disso, os dados epidemiológicos das aves analisadas demonstram que a infecção por Salmonella Gallinarum nesses casos está associada ao contato com aves silvestres e falhas de manejo sanitário.(AU)

Typhoid fever presenting as acute psychosis in a young adult: case report and literature review of typhoid psychosis

@#The rarity of acute psychosis in typhoid fever can result in delayed and misdiagnosis of the condition. We report a case of a 20-year-old man who presented with fever and acute psychotic symptoms. This was associated with headache, dizziness, and body weakness. There were no other significant symptoms. Neurological examination revealed reduced muscle tone of bilateral lower limbs but otherwise unremarkable. The computed tomography (CT) scan of his brain showed no abnormality. Blood specimens for microbiological culture grew Salmonella Typhi. This isolate was susceptible to chloramphenicol, ampicillin, ceftriaxone, ciprofloxacin, and trimethoprim-sulfamethoxazole. He was treated with intravenous ceftriaxone for one week and responded well. He was discharged with oral ciprofloxacin for another week. The repeated blood and stool for bacterial culture yielded no growth of Salmonella Typhi.

Intestinal Parasites and Salmonella typhi Infection among Food-handlers in Port Harcourt Metropolis, Nigeria

Background: Intestinal parasites andSalmonellainfections are of main public health concerns in Nigeria and the world, especially in developing countries where access to safe water and hygienic food handling practices by food handlers is a challenge. Consequently, food-handlers play a major role in the transmission of these types of foodborne diseases.Objective: This study was to determine the preponderance of intestinal parasites and Salmonella typhiamong food-handlers in selected areas in Port Harcourt.Materials and Methods: A total of 480 food-handlers (195 males and 285 females) of various educational levels were sampled. Stool samples were collected and analyses were carried out using direct smear examination and formol-ether concentration technique -adopted for nvestigation of intestinal parasites and deoxycholate citrate agar and Salmonella-Shigella agar for the cultivation of Salmonella typhi.Results:Of 480 food-handlers examined, comprisesof 195(40.6%) males and 285(59.4%) females,-majority (85.4%) were young adults aged 20-40 years. 47.9% of them -had education above secondary educational level. The preponderance of intestinal parasites was 48(10.0%) and implicated were Ascaris lumbricoides(41.7%), hookworm (33.3%) and Trichuris trichiura(25.0%). No intestinal protozoa were identified. Prevalence of 30(6.3%) was recorded for Salmonella typhi.Conclusion:Prevalence of Intestinal Parasites and S.typhi infection is relatively low among food handlers in Port Harcourt, but indicates the important role food handlers play in the transmission of the infection. Therefore, awareness should be step-up forthe food handlers to avoid escalation of these infections

Seropositividad de H. pylori y Fiebre Tifoidea en Pacientes iraquíes con dispesia / Seropositivity of H. pylori and Typhoid Fever in Dyspesia Iraqi Patients

Background: There are many studies highlight the association between Helicobacter pylori seropositivity with typhoid fever in human populations and there is no study in Iraq. Aim: Our study designed to estimate the correlation between seroprevelace of H. pylori and Typhoid fever in clinically examined patients as dyspeptic and typhoid fever infected. Methods: From May (2016) to February (2018), a total of 213 patients (134 females and 79 male) attending an enterology outpatient clinic in AL-Najaf province, Iraq. The patients with age range from 10 to 90 years and with symptoms of dyspepsia and typhoid fever (as fever, diarrhea, headache), were referred to serologic diagnosis of antibodies against H. pylori (IgG) and Typhoid (IgG and/or IgM), using the Rapid Tests Cassette. Results: Of a total of 213 clinically examined as dyspeptic and typhoid fever infected patients,134 (63.0%) were females and 79 (37.0%) were males.In this study, 82 (38.5 %) of 213 patients were seropositive for typhoid fever and 131 patients were seronegative. Moreover, 128 (60.1 %) of 213 patients were seropositive for H.pylori IgG (51 case,39.8%, typhoid seropositive, and 77 case,60.2%, typhoid seronegative) and 82 were seronegative. The serologic co-infection diagnosed in 51 (24.0%) patients. The seropositivity of typhoid fever was higher in H. pylori seropositive patients, co-infections (62.2 %), than H. pylori seronegative patients (37.8%). The co-infection was more in female (64.7%) than male (35.3%). In respect of age H. pylori seropositivity was more prevelance (25.8%) in 30s age group where as co-infection was more prevalence in 40s age group (29.4%). But the statistical analysis showed insignificant association of H. pylori with typhoid fever (P value = 0.6203), gender (P value = 0.4770) and age groups (P value = 0.0745). Conclusion: Our study indicates that H. pylori seropositive dyspepsia more susceptiple to typhoid fever particularly in female and 40s ages and suggest there was insignificant relationship amongst seropositivity of H. pylori and typhoid fever within dyspepsia patient

Prevalence of Waterborne Diseases in Bade, Nguru and Machina Local Government Areas of Yobe State-Nigeria

Waterborne diseases are mainly caused by consuming food or water tainted with faecal matter or urine of human or animal which contains pathogens. Records have shown that YobeState is one of the states in Nigeria that have recorded mortalities due to waterborne infections. Thisstudy is aimed at identifying common waterborne diseases such as cholera, typhoid, infectious hepatitis, giadiasis, amoebiasis, and dracunculiasis between 2017 and 2019 in three local Government Areas (L.G.As) of Yobe State. Personal interview was employed to generate information from the local people on sources of drinking water in three sampled geo –political wards (Bade, Nguru and Machine L.G.As). Results revealed that most of the dwellers in the study area drink from non –potable water sources such as faucets, hand pump, wash boreholes, wells, rivers, pools and creeks. Results also show that people from the study area do not drink potable water. A total of 1204 cholera cases were reported between 2017 and 2019 in the study areas with Machina L.G.A having the highest number of cases (446) representing 37.04% of the total cases. Mortality due to cholera outbreak in all the surveyed LG.As was 124 with Bade L.G.A having the highest number (43) constituting 34.68% of total mortalities in the study areas. A total of 11,938 persons were infected with typhoid during the study period and Nguru L.G.A recorded the highest number of infections (4,438) representing 37.18% of total infections. Gender based percentage prevalence of typhoid in the study is higher in males (52.83%) than females (47.18%). Recommendations on how to overcome the menace have been highlighted.

Typhidot IgM as a reliable and rapid diagnostic test for typhoid fever among children in a tertiary care hospital

Background: Typhoid fever still continues to be a major public health problem in Nepal. A clinical spectrum of typhoid varies widely. It causes significant complication as well as mortality. A simple, reliable, affordable and rapid diagnostic test has been a long felt need of the clinicians to prescribe specific medication, adopt prevention of the emergence of antibiotics resistance and overall reduce the disease burden in the community.Methods: The prospective descriptive study was performed in 125 children between 2 years to 15 years of age admitted to the Pediatrics Department from September 2017 to September 2018. Blood culture, Typhidot rapid IgM were performed. MEDCALC software was used to calculate 95% confidence interval for sensitivity, specificity, predictive value positive, predictive value negative and accuracy. Kappa test was used to determine the agreement between Typhidot IgM and blood culture methods.Results: The study consisted of 125 children with acute febrile illness for more than 3 days with clinical symptomatology, consistent with typhoid fever. The reliability of Typhidot IgM in relation with blood culture and the study lighten that sensitivity 92.3% (95% CI: 63.9, 99.8), specificity 49.1% (95% CI: 39.5, 58.7), PPV 17.4% (95% CI: 14.2, 21.1), NPV 98.2% (95% CI: 89.2, 99.7) and accuracy 53.6% (95% CI: 44.5, 62.6). The two methods i.e. Typhoid IgM and blood culture shows significant agreement with p value 0.004.Conclusions: The present study demonstrates that Typhidot IgM has all the attributes of an ideal screening test.
