Pathogenic and zoonotic potential of bacterial flora of commercial fish ponds in Ibarapa Central Local Government Area of Oyo State, Nigeria
(2020) Obisesan, O. M.; Oladosu, G. A.; Abegunde, P. T.; Ajibade, A. O.; Adah, A. D.; Oladejo, A. O.
Pathogenic and non-pathogenic bacteria are normal microflora of the aquatic ecosystem. The bacterial organisms isolated in this study are from fish and pond water samples collected from 3 farms, and they belong to the following families: Streptococcaceae, Staphylococcaceae. Enterobacteriaceae, Psedomonadaceae, Vibrionaceae and Aeromonadaceae. Seven of the 13 bacterial species isolated namely; Citrobacter freundii, Aeromonas hydrophila, Vibrio vulnificus. Pseudomonas aeruginosa, Aeromonas schubertii, Klebsiella pneumoniae and Edwardsiella tarda are pathogenic to fish in freshwater habitat, while almost all the 13 species are pathogenic to humans. These organisms are therefore of economically significant to commercially important farmed fishes, have zoonotic potential and are of public health importance to man. Strict hygiene and biosecurity measures become very important on fish farms to avoid disease outbreaks. Consumers should also avoid eating raw and lightly cooked aquatic products.
Pollution and health hazards of integrated livestock-cum-fish farming system in Nigeria
(CIFA, 1994) Ayinla, O. A.; Oladosu, G. A.; Ajiboye, M. O.; Ansa, E. J.
Adverse environmental conditions induced by beavy loading of fish ponds with livestock manure constitute serious. pollution and health hazards. Losses in form of fish mortalities, poor growth performance and outbreak of pathogenic diseases of fish and man have been observed. The extension of well documented information on the practise of integrated livestock-cum-fish-farming will go a long way in solving these problems.
