Assessment of benthic organisms (micro and macro invertebrates) in the
selected salt pans of east coast of Tamil Nadu, India

Abstract :

E.coli is a normal intestinal flora in animals and human beings. Diarrhoea causing E.coli is classified as Enterotoxigenic E.coli, Enteroinvasive E.coli, Enteropathogenic E.coli, and Enterohaemorrhagic E.coli (EHEC). EHEC is an emerging pathogen causing haemorrhagic colitis and Haemolytic Uremic Syndrome. The most common EHEC is E.coli O157:H7. In this study, E.coli is isolated from 80 faecal samples of avian species in Tamilnadu. Among the 80 E.coli isolates,22 were sorbitol non-fermentors. These sorbitol non-fermentors were subjected to drug susceptibility to 24 different antibiotics. All the biovars were resistant to aztreonam, piperacillin and ticarcillin.95 per cent strains were resistant to carbencillin, cefazolin, ceftazidime and cefixime. Multiple drug resistance was observed.
