Diarrhea is a major clinical problem in HIV-infected patients. There is a need to monitor antimicrobial susceptibility patterns of enteric bacterial pathogens in order to ensure appropriate treatment and control of infections. The objectives of this study was to identify and determine the magnitude of potential enteric pathogens including Salmonella,(More)
The lytic bacteriophage which produces the hydrolase enzyme capable of depolymerizing exopolysaccharide of Klebsiella pneumoniae and of other bacteria was isolated earlier. In this study, a simple method of depolymerase purification from the phage lysate by dissociating the enzyme from the phage particle was developed. The bacteriophage showed a relatively(More)
Thermotolerant Campylobacter spp. are frequent causes of diarrhoea in humans worldwide mostly originating from poultry. It has been suggested that extensive veterinary use of antibiotics is largely responsible for resistance in human isolates. During a 4-month period from January to April 2004, 192 Campylobacter spp. were isolated from fecal samples of 485(More)
BACKGROUND Schistosoma mansoni is one of the parasites with high public and medical importance in Ethiopia. However, information is scarce about S. mansoni epidemiology in people living with higher risk of infection in Jimma town. This study was designed to determine point prevalence, intensity and risk factors of S. mansoni infection among residents nearby(More)
Hospital acquired infections are recognized as critical public health problems. Infections are frequently caused by organisms residing in healthcare environment, including contaminated medical equipment like Stethoscopes. To determine bacterial contamination, bacterial profile and anti-microbial susceptibility pattern of the isolates from stethoscopes at(More)
BACKGROUND Human immunodeficiency virus (HIV) infection and its treatment cause renal diseases. Renal disease is associated with an increasing cause of morbidity and mortality in HIV positive individuals than in the general population. It has been also associated with adverse outcomes, such as complications of decreased renal functions and progression to(More)
