Antibiotic-resistant human pathogens in integrated fish farms

The occurrence of antibiotic-resistant human pathogenic bacteria in integrated fish forms was studied in a Southeast Asian country. A total of nine fish ponds was sampled for Salmonella Vibrios Aeromonas and Plesiomonas. Salmonella spp. were present in 28 percent of samples of fish and benthic water/sediment. Aeromonas hydrophila in 67 percent of samples of fish Plesiomonas shigelloides in 22 percent samples of fish and Vibrio parahaemolyticus in 11 percent of the samples of fish and benthic water/sediment. Results showed that significant levels of antibiotic-resistant human pathogenic bacteria occur in aquaculture ponds where antibiotics are routinely incorporated into animal feeds. Antibiotic-resistant strains of Salmonella Aeromonas hydrophila and Plesiomonas shigelloides were isolated from fish samples.

Abstract

The occurrence of antibiotic-resistant human pathogenic bacteria in integrated fish forms was studied in a Southeast Asian country. A total of nine fish ponds was sampled for Salmonella Vibrios Aeromonas and Plesiomonas. Salmonella spp. were present in 28 percent of samples of fish and benthic water/sediment. Aeromonas hydrophila in 67 percent of samples of fish Plesiomonas shigelloides in 22 percent samples of fish and Vibrio parahaemolyticus in 11 percent of the samples of fish and benthic water/sediment. Results showed that significant levels of antibiotic-resistant human pathogenic bacteria occur in aquaculture ponds where antibiotics are routinely incorporated into animal feeds. Antibiotic-resistant strains of Salmonella Aeromonas hydrophila and Plesiomonas shigelloides were isolated from fish samples. Of the 118 microorganisms isolated and tested during the study 11 percent were resistant to nalidixic acid 12 percent to oxolinic acid 17 percent to chloramphenicol 6 percent to neomysin 74 percent to oxytetracycline 75 percent to tetracycline 47 percent to furazolidone and 25 percent to sulphametoxazole combined with trimethoprim. Plasmids were detected in a strain of Salmonella other members of the Enterobacteriaceae and several Pseudomonas species. Health risks and implications associated with these findings are discussed
