Serotypic and antibiotic susceptibility pattern of Salmonella species isolated from cases of gastroenteritis at Infectious Diseases Hospital (IDH), Delhi from 1997-2000.
A total number of 11,551 stool samples/rectal swabs obtained from acute gastroenteritis cases admitted at Infectious Diseases Hospital (IDH), Delhi during a period of four years from 1997-2000 were processed at National Institute of Communicable Diseases (NICD), Delhi to look for the presence of enteropathogens. One hundred twelve Salmonellae species belonging to different serotypes were isolated. The commonest species was S. typhimurium, accounting for 31% of isolates, followed by S. weltervreden (19%), S. litchfield (15%) and others. 61% of S. typhimurium isolates depicted multidrug resistance to Chloramphenicol, Tetracycline, Furazolidone and Co-trimoxazole. However, none showed resistance to quinolones and third generation cephalosporins. Estimation of minimum inhibitory concentration (MIC) for S. typhimurium against Ampicillin, Chloramphenicol and Cephalothin was carried out by E test. A good correlation between disc diffusion technique and E test was observed.
