Abstract:
This study was conducted in river Nile state north Sudan aimed to give base line information on the potential transmission of salmonella spp from water source to fish in mudy season, In AL- fadlab and Al –aked stations, twenty samples of water and schilbidaespp fish were collected from the two stations and transfers to the laboratory to physiochemical and microbial analysis samples was performed using standard bacteriological procedures. Swap from each fish gill was microbiologically analyzed for salmonella spp. Results indicates that there were (33.3%) of fish samples infected with Salmonella spp, also salmonella spp in Alfadlab Location was 44.83±8.67 in fish and 5.00±1.00 in water while it was 9.33±1.45 in fish and there was no growth in water In Alakad Location there was significant different P<0.01in the two locations. The plate count in water of Alfadlab was 8.13±1.87 while it was 11.67±2.04in Alakad statistical analysis indicates No significant difference in the two location. There was No significant difference P<0.01 in Weight (g) and Length (cm) in studied fish spp and water turbidity and temperature from the two location, but there was significant difference P<0.01 in water ph. which is 7.62±0.04and 9.53±0.08 in Alfadlab and Alakad respectively.
