Role of Escherichia coli and Salmonella spp in diarrhoeal syndrome in pre and post weaning wild piglets in the semi-wild raising model

Abstract

The role of E. coli, Salmonella spp in diarrhoeal syndrome in the piglets was determined from the F2 hybrid wild pig {♂ wild pig x ♀ F1 (♂wild pig x ♀ local pig)} raising in the Research and Development Branch for Indigenous Flora and Fauna. The rate of piglet fecal sample infected with E.coli was 78.57%; Meanwhile, this rate from the weaned pig fecal samples was 69.23%. The isolated E.coli, Salmonella strains showed the typically biological, chemical characteristics and they were identified as the cause of diarrheal syndrome in the piglets. The isolated E.coli, Salmonella strains were all the virulent strains, killing 100% of the tested animals within 24-72h after injection. The isolated E. coli, Salmonella strains were susceptible with Amikacin and Ceftiofur (100%), followed by Flumequine and Norfloxacin. But 100% of these strains were resistant to Colistin and Tetracycline.
