OBJECTIVE To characterize mechanisms of hand contamination with faecal indicator bacteria and to assess the presence of selected pathogens on mothers' hands in Tanzania. METHODS A household observational study combined with repeated microbiological hand rinse sampling was conducted among 119 mothers in Dar es Salaam, Tanzania. All hand rinse samples were analysed for enterococci and Escherich...

Introduction: Probiotics are defined as live non-pathogenic microorganisms and if administered in adequate amounts, can have beneficial effects on their hosts. This study aimed to isolate Gram-positive bacteria from different sources and to evaluate their probiotic properties. Methods: We obtained five samples from various sources including yogurt, infant feces, cheese, and soil under aseptic m...

Microbiological monitoring of bivalve mollusc production areas by national or regional authorities is usually undertaken as part of a programme to classify the areas according to the perceived risk of the presence of pathogenic microorganisms based on the concentrations of faecal indicator bacteria present in the area. The indicator bacteria used are generally of the coliform group: total colif...

background :    due to excessive consumption of synthetic drugs, drug resistance rate of pathogenic bacteria is increasing and there is an ever-increasing need to find new safe compounds to tackle this problem. this study was conducted to investigate the consequences of chavill extract on the growth and viability of gastrointestinal pathogenic bacterium and probiotics bacteria.   methods :    t...

Studies of the occurrence and survival of sewage-origin bacteria in coastal waters and sediments continued this year at the marine microbiology laboratory at California State University at Long Beach. The goal of these studies has been to determine what relationships, if any, exist between the routinely sampled indicator bacteria (e.g., coliforms, fecal streptococci) and pathogenic bacteria (e....
