Epidemiological Studies on Transmission of some Avian Pathogens from Fish Farms to Water Fowls in Kafr El-sheikh Governorate, Egypt

Abstract

Integrated Waterfowl is common in Kafr El-Sheikh Governorate. The infection with many bacterial and /or viral diseases due to using poultry litter as a fertilizer in fish farms is studied. Fifty litter samples, sixty nine fish pond water samples, two hundred fecal swabs from integrated waterfowl and sixty samples from liver from these waterfowl were collected for surveying some pathogens which may be present in litter and transported to fish ponds and infect waterfowl. Results of this survey revealed the isolation of 19 Salmonella spp. (4 isolates from litter, 2 isolates from fish pond water, 8 isolates from fecal swabs of waterfowl and 5 isolates from waterfowl liver), 17 Staphylococcus spp. (7 isolates from litter, 3 isolates from fish pond water, 5 isolates from fecal swabs of waterfowl and 2 isolates from waterfowl liver) and 59 E. coli isolates (9 isolates from litter,16 isolates from fish pond water, 22 isolates from fecal swabs of waterfowl and 12 isolates from waterfowl liver) isolates were obtained from different samples.
