Antibiotic resistance profiles of the bacteria isolated from some finfish species in Iskenderun Bay, (Northeastern Mediterranean Sea), Turkey

Abstract

This study was conducted on the microbial flora isolated from gills and intestine tissues of commercially important finfish species: saddled seabream (Oblada melanura), gilthead sea bream (Sparus amnia), Bogue (Boops boops), horse mackerel (Trachurus mediterraneus), red mullet (Mullus barbants), brushtooth lizardfish (Saurida undosquamis), grey mullet (Mugil cephalus), threadfin bream, (Nemipterus randalli), which were caught from the Iskenderun Bay at 6 different locations (local fishermen's fish market) were evaluated. The Serratia spp., Enterobacter aerogenes, Klebsiellu pneumoniae, and Enterobacter cloacae were isolated from the gill samples, while E. aerogenes, E. cloacae, Proteus vulgaris, K. pneumoniae and Pseudomonas fluorescens were isolated from the fish intestine samples. E. aerogenes (68.4%) Serratia spp. (53.3%), E. cloacae (50%) and K. pneumoniae (44.4%) showed high level of resistance against ampicillin. K. pneumoniae also showed high resistance against Cefepime (52.9%) and Ciprofloxacin (47.1%). Pseudomonus species exhibited high level of resistance against Cephalosporin.
