A cross sectional study on the seroprevalence of bovine brucellosis in Al-Najaf Province in Iraq

الملخص EN

Brucellosis is an endemic disease in many countries of the middle east including Iraq, despite the high attempts to control the disease in animals using vaccination programs.

The study was conducted from January to March 2012, to determine the prevalence of bovine brucellosis in the Al-Najaf province in Iraq, which represent risk factors associated with brucellosis in cattle.

Blood samples were collected from 172 cows and 15 bulls of 20 dual-purpose cattle herds.

Serological examinations are the most useful and widely used tool for the diagnosis of brucellosis in man and animals.

All animal serum samples were tested by the Rose Bengal plate test (RBT), and the positive cases were confirmed by competitive enzyme-linked immunosorbent assay (c-ELISA).

The overall prevalence of brucellosis was 5.81% divided between 5.81% in females and 0% in males, and 40% as herd numbers level.

Females showed a higher seropositive reaction to the disease than males.

In conclusion, this study demonstrated the presence of the disease and detected the seropositive reactions in animal samples in different farms of the province, with a difference in infection rate regarding the risk factor.

Sanitary measures must be taken to avoid the occurrence and spread of the disease in humans and animals.
