Abstract

To determine the scope of urinary pathogens isolated in the Public Health Bacteriology Laboratory, their antibiotic susceptibility patterns and the incidence of haemolytic bacteria in Harare. Prospective study. Patients of different age groups attending various clinics in Parirenyatwa Hospital, Harare, between October 1995 and April 1996 were enrolled for the study. A laboratory based study at the Bacteriology Unit, Public Health Laboratories, Harare. 1,760 urine specimens obtained from male and female patients suspected of having UTI. Out of a total number of 1,760 urine specimens screened only 473 (26.9pc) were positive for UTI pathogens. Four hundred and nineteen (88.5pc) and 46 (9.7pc) of the 473 positive UTI pathogens were Gram negative and Gram positive bacteria respectively. Eight (1.7pc) of the positive isolates were Candida spp. The commonest pathogen isolated was Escherichia coli (40.5pc), followed by Klebsiella spp. (22.1pc) and Proteus spp. (7.2pc). Of the positive isolates 184 (38.9pc) and seven (1.5pc) were beta- and alpha-haemolytic respectively. Of E. coli isolates 72pc were beta-haemolytic. Sex distribution showed that 53pc and 47pc of the UTI pathogens were isolated from males and females respectively. E. coli...Continue Reading

Antifungals (ASM)

An antifungal, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis, cryptococcal meningitis, and others. Discover the latest research on antifungals here.

Allergy & Infectious Diseases (ASM)

Allergies result from the hyperreactivity of the immune system to some environmental substance and can be life-threatening. Infectious diseases are caused by organisms including bacteria, viruses, fungi and parasites. They can be transmitted different ways, such as person-to-person. Here is the latest research on allergy and infectious diseases.

Aminoglycosides

Aminoglycoside is a medicinal and bacteriologic category of traditional Gram-negative antibacterial medications that inhibit protein synthesis and contain as a portion of the molecule an amino-modified glycoside. Discover the latest research on aminoglycoside here.
