An environmental study was undertaken to examine the prevalence and diversity of Aeromonas species in the river Narmada at Jabalpur (MP), India, from August 1996 to August 1998. Total of 90 water samples were collected from different sampling stations during the study period and all gave positive results for aeromonads. Out of 119 isolates, 110 isolates belonged to 8 different Aeromonas genomospecies, whereas 9 isolates could not be identified to species level. The drug resistance pattern of these isolates showed certain variations, which disclosed the resistance potential of different Aeromonas genomospecies surviving in aquatic environment. Quinolones showed excellent activity against all the aeromonads.
