dc.description.abstractBacterial fish diseases were considered to be the main cause of high mortalities and economic losses among the cultured freshwater fish in Andhra Pradesh. The aim of the present study was to identify the bacterial strains isolated from farm raised Indian major carps majorly exhibiting bacterial haemorrhagic septicaemia, abdominal dropsy, tail rot and fin rot in two districts viz., SPSR Nellore and West Godavari districts of Andhra Pradesh, India. Further, the susceptibility of the isolated bacterial strains to the currently available antimicrobial therapeutics was determined. In the present study, the pathogenic bacteria isolated were species of Aeromonas, Pseudomonas and Enterobacteriacea family. 7 species of Aeromonas viz., Aeromonas hydrophila, A. tecta, A. caviea, A. sobria, A. veronii A. schubertii and A. encheleia; 4 species of Pseudomonas viz., Pseudomonas sp., Pseudomonas stutzeri, P. diminuta and P. fluoroscenes; 5 species of Enterobacteriacea family viz., Citrobacter freundi, Serratia rubidaea, S. fonticola, Klebsiella pneumoniae ssp pneumniae and Enterobacteriacea group were identified and characterized by conventional biochemical tests. The prevalence study carried out for a period of one year from July 2018 to June 2019 in the above two districts revealed the dominance of aeromoniasis caused by Aeromonas spp. Significantly higher prevalence (P 0.05) with that of aeromoniasis. Further, prevalence of bacterial diseases did not vary significantly (P > 0.05) with respect to fish species, geographic location and seasonality. In vitro antibiotic sensitivity study revealed that gentamicin, ciprofloxacin, amikacin and trimethoprim were found to be more effective against Aeromonas sp., Pseudomonas sp. and Enterobacteriaceae family. Multiple antibiotic resistance (MAR) study showed that all the species of Pseudomonas and Enterobacteriaceae family were MAR. Among Aeromonas sp., A. tecta and A. caviea were 100% MAR, however 80% of A. sobria, A. veronii and A. schubertii showed MAR and 50% of A. hydrophila strains only showed MAR. The MAR index of more than 0.2 was observed in all the bacterial strains of Aeromonas, Pseudomonas and Enterobacteriaceae family indicated that these bacterial strains might have originated from high risk sources of contamination. Haemolytic activity assay revealed that A. veronii (80%), A. schubertii, (60%), A. sobria (40%) and A. tecta (33.3%) were found to be β-haemolytic.en_US
