Abstract:
A total of 319 strains of Aeromonas hydrophila were isolated from 536 fish and 278 prawns for a 2-year period. All the
strains were tested for resistance to 15 antibiotics and 100% of the strains was resistant to methicillin and rifampicin followed by
bacitracin and novobiocin (99%). Only 3% of the strains exhibited resistance against chloramphenicol. The multiple antibiotic
resistance (MAR) indexing of A. hydrophila strains showed that all of them originated from high-risk sources

Abstract:
Five hundred and thirty six samples offishes and 278 prawn samples from the major fish market ofCoimbatore, South India,
were analysed for the prevalence of Aeromonas hydrophila over a period of2 years (June 1997–May 1999). The prevalence level of A.
hydrophila varied from 17.62% in prawns to 33.58% in fishes. More than 30% of the popular table fishes such as Sardinella
longiceps, Rastrelliger kanagurta, Mugil cephalus and Caranx sexfasciatus were tested positive for this organism. Among the
different species of the prawns analysed, Penaeus semisulcatus showed higher incidence (23.52%). Seasonal variation in the
prevalence levels of A. hydrophila in fish and prawns revealed a higher prevalence during the monsoon season during 1997–98 and
1998–99. Of the different body parts of the fishes analysed for A. hydrophila, the intestinal samples showed higher prevalence
(38.43%), followed by body surface (32.46%) and gill (29.10%). Considering the psychrotrophic nature and role of A. hydrophila as
a pathogen ofemerging importance, the considerably high levels ofthis organism in a popular food item such as fish and prawn
raises serious concern
