Abstract
This study was carried out to investigate theantibiotic susceptibility of Listeria species in
frozen, smoked and canned fish in Kaduna North Local Government Area of Nigeria. A total
of One hundred and eighty (180) fish samples comprising of 60 frozen, 60 smoked and 60
canned were purchased from the fish mongers at the three major markets in Kaduna North
L.G.A (Kawo, Abubakar Gumi and UnguwarRimi markets). Sampling was done once a
weekly. Listeria species were isolated using pre-enrichment selective medium and were
identified by conventional biochemical tests. The antibiotic susceptibility was determined by
Kirby-Bauer disk diffusion method on Muller Hilton Agar (Oxoid, UK) Nine antibiotics
tested were Amoxicillin (25ug) Tetracycline (ug), Erythromycin (15ug), Gentamycin (30ug)
Chloramphenicol (30ug) Ciprofloxacin (5ug) Streptomycin (10ug) Trimethoprin (5ug) and
Oxacilin (1ug). Results showed that from the 180 samples, 9 of the positive isolates were L.
grayi, while 15 were L. ivanovii found to be contaminated with Listeria species. Antibiotic
susceptibility testing showed that Listeria sppisolates were susceptible to gentamicin (the first
choice antibiotic) used in the treatment of listeriosis. The sensitivity regimens were 24(100%)
for Gentamicin as the most effective, followed by 22(92%) for Chloramphenicol, 21(88.0%)
for Amoxicillin and 19(79%) for Oxacillin. Antimicrobial resistance pattern Erythromycin
(ER) occurred in 5 of the 24 Listeria species isolates. The antimicrobial resistance pattern
showed by Listeria species in this study showed that there is a potential threat to health and
safety of the public. Therefore it is recommended that the usage of antibiotics in both human
and veterinary medicine should be monitored appropriately.
