Serological Survey Against Some Viral Diseases in Camels in Sharkia Governorate, Egypt

365 sera samples were collected during 1997 from two groups of camels in Sharkia governorate, Egypt. The first group: 190 sera samples collected from slaughtered camels at Belbas abattoir, while the second group: 175 sera samples collected from individual camels which were in contact with cattle herds. Sera samples were tested by serum neutralization test for the presence of antibodies against infectious Bovine Rhinotracheitis (IBR), Parainfluenza-3 (PI3), Bovine Viral diarrhea (BVD) and Rift Valley fever (RVF). The percentage of seropositive in first group was: IBR (2.1%), PI3 (1.5%), BVD (1%), and RVF (4.7%) while in the second group it was: IBR (2.8%), PI3 (2.3%), BVD (1.7%) and RVF (6.8%). Results of the present study indicate that camels can be infected sub clinically with these diseases and this most probably plays a significant role in the epizootiology of these viral diseases.
