Abstract:

Chromobacterium violaceum is an opportunistic human pathogen causing a range of gastric infections and occasionally septicemia. This Gram-negative bacillus is a common inhabitant of soil and water in tropical and subtropical areas of the world. Infection occurs after contamination of damaged skin exposed to soil or environmental water. Alternatively, systemic infection can follow the aspiration or ingestion of contaminated water. The major features of infections by C. violaceum are, in generally, rapid clinical course, multiple visceral abscesses, and high mortality. Genomic data on the type strain ATCC 12472 has provided a comprehensive basis for detailed studies of pathogenicity, virulence and drug resistance genes. In this study, the susceptibility of this organism was tested on a variety of drugs at different concentrations, in solid and liquid media. C. violaceum shown to be resistance to ampicilin, penicillin, rifampicin, erythromycin, vancomycin and also to ethidium bromide. The bacteria was susceptible to gentamicin, tetracycline, chloramphenicol, cotrimoxazole, kanamycin, streptomycin and nalidixic acid, at the tested concentrations.
