Abstract
This work reports on the prevalence, antibiotic resistance and molecular characterization
of Aeromonas species, Salmonella serovars and Listeria species isolated from catfish
(Clarias gariepinus) and tilapia (Tilapia mossambica) obtained from wet markets and
ponds (earthen ponds and ex-mining pools) in Northern region of Malaysia. A total 163
of Aeromonas spp, 43 of Salmonella serovars, and 54 Listeria spp. was isolated from 32
catfish carcass rinse, 32 catfish intestines, 32 tilapia carcass rinse, 32 tilapia intestines
and 44 water samples. Catfish, tilapia and water samples were obtained from nine wet
markets and eight ponds in Penang, Kedah and Perak, Malaysia (2008 – 2009).
Prevalence of Aeromonas spp., Salmonella serovars and Listeria spp. in catfish was
14/32 (43.8%), 9/32 (28.1%), and 10/32 (31.3%), respectively. Prevalence of Aeromonas
spp., Salmonella serovars and Listeria spp. in tilapia was 21/32 (65.6%), 14/32 (43.8%),
and 18/32 (56.3%), respectively. Aeromonas spp. was resistant to clindamycin, rifampin,
and spectinomycin. Salmonella serovars were resistant to clindamycin, rifampin, and
tetracycline. Listeria spp. was resistant to ceftazidime and clindamycin. The
predominant antibiograms of A. hydrophila was AzmDaRdSh (6/62).
