Abstract
Introduction: Q fever is a zoonotic disease caused by the bacterium Coxiella burnetii. Clinical presentation in humans varies from asymptomatic to flu-like illness and severe sequelae may be seen. Ruminants are often sub-clinically infected or show reproductive disorders such as abortions. In Egypt, only limited data on the prevalence of Q fever in cow’s milk are available. Methods : The present study was conducted on spring 2018 and included 326 milk samples from lactating cows from two different sampling points at Dakahlia Governorate, Egypt. Results : from 326 milk samples 102 were positive by ELISA method by a percent 31% and 46 positive from ELISA were tested by PCR and found 9 samples were positive by a percent 20%. Conclusion: Our results highlight evidence of Coxiella burnetii antibody in raw cow’s milk in Dakahlia Governorate. Findings from this study show that exposure to Coxiella burnetii is common in cows so it is important to apply HACCP system in the farm to get high quality milk free from zoonotic bacteria moreover the application of control program for ticks .Disease awareness among physicians, veterinarians and animal owners has to be raised. Future epidemiological investigations have to elucidate the impact of Q fever on human health and on the economy of Egypt.
