Aim: In this study, it was aimed to determine the presence of Vibrio spp.,
Aeromonas spp., and Listeria spp. in finned fish and shrimps consumed in
Turkey and the antibiotic resistance profile of the isolates using disc diffusion
method.
Materials and Methods: In the research, 300 seafoods obtained at different
times were used as material. Following isolation by classical cultural method,
classical PCR was performed to confirm the isolates at genus level and to
identify at species level for pathogenic species.
Results: Finfish and shrimp samples were contaminated with Vibrio spp.,
Aeromonas spp. and Listeria spp. with the rate of 19.4% (33/170), 14.7%
(25/170), 4.1% (7/170) and 13.8% (18/130), 13.1% (17/130), 6.2% (8/130),
respectively. Twenty-nine (9.7%) and 9 (3.0%) of the Vibrio spp. isolates were
identified as V. parahaemolyticus and V. cholerae, respectively. Thirty (10%) of
the Aeromonas spp. isolates were detected as A. hydrophila. L. monocytogenes
and V. vulnificus was not detected in any of samples. Antibiotic resistance
profile of the V. parahaemolyticus, V. cholerae, A. hydrophila and Listeria spp.
isolates was streptomycin (71.4%), teicoplanin (71.4%), ampicillin (87.5%),
teicoplanin (75%); streptomycin (80%), ampicillin (75%), cefixime (75%),
penicillin (75%), sulfamethoxazole/trimethoprim (100%), tetracycline
(75%); erythromycin (93.8%), vancomycin (81.2%), amoxacillin/clavulanic
acid (78.6%), ampicillin (85.7%), cephalothin (92.9%), penicillin G (92.9%);
and cephalothin (37.5%-42.9%), erythromycin (37.5%-42.9%), penicillin G
(37.5%-42.9%), tetracycline (37.5%-42.9%), respectively.
Conclusion: As a result, it is thought that fish and shrimp consumed in Turkey
may be contaminated with pathogenic Vibrio and Aeromonas species, and
antibiotic-resistant isolates may pose a risk to public health.
