Abstract

The study was aimed to characterize, and determine antibiogram of C. perfringens type A isolated from the feces of human and animal diarrhoeal cases, as well as healthy animals, meat of pigs and goats, gills and intestine of fish and samples from fish pond. A total of 460 samples, including human diarrhoeal cases (n = 130); diarrhoeal cases of pig (n = 52) and goat (n = 50); fecal samples from healthy pig (n = 50) and goat (n = 50); meat samples viz. pork meat (n = 52); goat meat (n = 50) and fish including their environmental sources (n = 26) were used for isolation and identification of C. perfringens type A. All the biochemically confirmed isolates were positive for species-specific 16S rRNA and cpa genes by PCR assays. Toxinotyping of C. perfringens type A isolates showed that overall prevalence of C. perfringens type A with only cpa(+) gene was 43.2%; with cpa(+) and cpb2(+) genes was 45.4%; with cpa(+) and cpe(+) genes was 4.9%; however, with cpa(+), cpb2(+)and cpe(+) genes was 6.6%. Antimicrobial susceptibility testing revealed that 83.7% of isolates were resistant to three or more antibiotics.

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.
