Resistance to broad spectrum β lactams, mediated by extended spectrum beta lactamase (ESβL) and AmpC βL enzymes is fast spreading in Nigerian hospitals. Production of these enzymes has resulted in treatment failure especially if one of the second or third generation cephalosporins is used. A study was undertaken to determine the prevalence of each enzyme and coproduction of the two enzymes amon...

Aim : To find out the organisms causing endometritis in cattle and to determine their in vitro sensitivity to various antibiotics Materials and methods: Thirty uterine secretion samples, 9 from Holstein Friesian and 21 from Jersey cows were collected in and around Namakkal district of Tamil Nadu from clinical cases of endometritis. The bacteria isolated both aerobically and anaerobically from e...

Herbal antimalarials still remain an alternative to our traditional communities who can not afford orthodox antimalarials. This study was aimed at investigating the microbial quality of six herbal antimalarials using standard microbiological methods. Of the six preparations analyzed, "schnapps", palm wine and water were the media of preparation; the water base preparations recorded higher micro...

Sepsis is one of the major challenges of today. Although gram-positive bacteria related infections are more prevalent in hospital setting, the highest mortality rate is associated with gram-negative microorganisms especially Enterobacteriaceae. Enterobacteriaceae, including Escherichia coli, Klebsiella spp., Proteus spp., Enterobacter spp. and Serratia spp. Resistance to β-lactams in Enterobact...

The study was conducted to record the microbial inhabitants of the nirmal ear canal and isolate microbial infective agents in otitic ears in dogs. The microorganisms were isolated from 87.5% of normal ears, which included Staphylococcus spp. (37.5%) followed by S. pyogenes (25.0%), P. aeruginosa (12.5%) and E. coli (12.5%). The fungus Candida spp was isolated from 37.5% normal ears, which was a...

Surgically induced duodenal reflux results in cancer development in the rat esophagus. One proposed mechanism of carcinogenesis relies on the production of carcinogens in the presence of bacterial overgrowth. Against this background, intestinal microflora in the rat jejunum was analyzed before and after reflux-inducing surgery. Total gastrectomy and esophagojejunostomy were performed on Sprague...

The aim was to study the bacterial load and isolate potential pathogens and food spoilage bacteria from kitchen tables, including preparation tables and dining tables. Methods. A total of 53 households gave their consent for participation. The samples were collected by swabbing over an area of 5 cm by 5 cm of the tables and processed for bacterial count which was read as colony forming units (C...

as pseudomonas, acinetobacter, and staphylococcus that appropriate disinfection can reduce these pathogens. the aim of this study was to evaluate the effect of different disinfectants on gram-negative bacteria isolated from the surface of accidents and burn hospital in yazd. materials and methods: in this study, 240 samples were randomly collected from different parts of accidents and burn hosp...

BACKGROUND The discharging ear is a common presentation in medical practice affecting all age groups but primarily children. This study shows the current aetiological causes of ear discharge and their antibiograms, data which would guide empirical treatment of ear infections, and also form a basis for further research. METHODOLOGY This was a retrospective review of laboratory records of all e...

The activity of azlocillin, a new semisynthetic penicillin, was determined against 582 clinical isolates of gram-negative bacilli and gram-positive cocci. Over 75% of the isolates of Pseudomonas aeruginosa were inhibited at a concentration of 12.5 mug or less per ml. Azlocillin is also active against indole-negative and -positive Proteus spp., inhibiting 98 and 71%, respectively, at a concentra...
