Abstract Background Bacterial pathogens cause substantial diarrhea morbidity and mortality among children living in endemic settings, yet antimicrobial treatment is only recommended for dysentery or suspected cholera. Methods AntiBiotics Children with severe Diarrhea was a 7-country, placebo-controlled, double-blind efficacy trial of azithromycin 2–23 months age watery accompanied by dehydration malnutrition. We tested fecal samples enteric utilizing quantitative polymerase chain reaction to...

human papillomavirus (HPV) is the most common sexually transmitted virus in world. Prevalence of infection differs, with highest rates reported sub-Saharan African, including country Tanzania. In pregnancy, hormonal changes and immune seem to facilitate HPV persistence, increasing cancer risk vertical transmission towards placenta fetus. The burden still high despite multiple screening detection test available. AmpFire® assay a novel nucleic acid isothermal amplification real-time...

To augment the keratinolytic ability of Bacillus halotolerans L2EN1 isolated from poultry farm (Nahan, District Sirmour) Himachal Pradesh, different cultural conditions were optimised using One Variable at a Time (OVAT) approach accompanied by Response Surface Methodology (RSM). Optimisation results revealed that after 3rd day incubation, maximum enzyme activity was attained 45 °C, pH 11.0 with 12.5% inoculum size in presence Mn2 + and EDTA production medium. Sucrose (1.5%) yeast extract...

Assessment of gestational age (GA) is key to provide optimal care during pregnancy. However, its accurate determination remains challenging in low- and middle-income countries, where access obstetric ultrasound limited. Hence, there an urgent need develop clinical approaches that allow inexpensive estimations GA. We investigated the ability urinary metabolites predict GA at time collection a diverse multi-site cohort healthy pathological pregnancies (n = 99) using broad-spectrum liquid...

Abstract Introduction Antimicrobial resistance (AMR) is a major public health challenge worldwide, threatening the important gains that have been made in reducing mortality due to infectious diseases. Despite current World Health Organization guidelines restricting antibiotics small subset of children with dysentery or suspected cholera, many diarrhea continue be treated antibiotics. We aim determine impact 3-day course azithromycin on risk AMR at 90 and 180 days after treatment, among their...
