Abstract

The present study attempted to determine the prevalence of pathogenic bacteria within two most popular small indigenous fish species of Bangladesh. A total of 51 infected fish samples were collected from different places in Bangladesh between April 2019 to December 2020. Among 51 infected fish samples (26 Pabda, & 25 Gulsha), 47(92.16%) were infected with pathogenic bacteria and 4(7.84%) were normal flora. From the total of 51 isolated bacterial strains, the highest number was 16(31.37%) for Vibrio spp., the second highest for Aeromonas spp, was 12(23.52%), and the next was 5(9.80%) for Streptococcus spp. On the other hand, Pseudomonas spp, only 4(7.84%) and the rest 3(5.88%) Flavobacterium spp., Citobacter spp., and Edwarsiella spp., Enterobacter spp., and parasite 1(1.96%). In our study, among the isolated pathogenic bacteria, 39(76.47%) were resistant to Amoxicillin and 28(54.90%) were resistant to Erythromycin. Whereas maximum sensitivity was found for Ciprofloxacin 35(68.63%). The isolation of emergent bacterial pathogens that impose a threat to fish is the main objective of this article.
