Abstract

In a period of two months, 232 consecutive urinary tract pathogens were isolated from hospitalised and non-hospitalised patients. Among the isolates, 200 (86.2%) were gram negative bacilli, including E. coli 109 (54.5%), Klebsiella species, 44 (22.5%), Enterobacter species 19 (9.5%), Proteus species 18 (9%), Morganella morganii 9 (4.5%) and Salmonella typhimurium, one (0.5%). Antimicrobial susceptibility testing to amoxycillin/clavulanic acid, nitrofurantoin, gentamicin and cefuroxime was performed using Stoke's method. Among the 109 E. coli isolates, 107 (98.2%), 104 (94.5%), 105(95.5% and 107 (98.2%) were sensitive to amoxycillin/clavulanic acid, cefuroxime, nitrofurantoin and gentamicin, respectively. Of the 44 Klebsiella isolates, 42 (95.5%), 41 (95.5%), 40 (90.9%) and 34 (77.3%) were sensitive to amoxycillin/clavulanic acid, cefuroxime, nitrofurantoin and gentamicin, respectively. There was no significant difference when the suceptibility patterns of isolates from hospitalised patients were compared to those from outpatients. Although the susceptibility pattern of urinary tract pathogens to the commonly used antimicrobial agents in the hospital is still favourable, there is a need to establish strategies to prevent emergen...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.
