Abstract

To assess the extent of involvement of different types of gram positive and gram negative bacteria and incidence of monomicrobial and polymicrobial cases in patients with bacteremia but without a record of the underlying clinical conditions of the patients. Antibiotic susceptibility patterns of isolates were also determined to guide clinicians in the management of such bacteremic cases especially where routine sensitivity testing is not performed. Case series. The study comprised patients attending different clinics in Parirenyatwa Hospital, Harare. A total of 817 blood cultures from patients, comprising 469 and 348 males and females respectively. There were no records of the underlying clinical conditions of the patients. Prevalence rates of organisms and their antibiograms using standard techniques and Kirby-Bauer disc diffusion method. Results obtained revealed that only 303(37.1%) of the 817 total samples screened were positive for either monomicrobial or polymicrobial bacteremia. Two hundred and eighteen (71.9%) and 85 of positive cultures were Gram positive and Gram negative bacteria respectively. Coagulase negative staphylococci (CNS) strains were the predominant organisms isolated (42.9%). Other organisms isolated were ...Continue Reading

Allergy & Infectious Diseases

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.

Antimicrobial Resistance (ASM)

Antimicrobial resistance poses a significant threat to the continued successful use of antimicrobial agents for the treatment of bacterial infections.

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.
