The effect of Brucellosis in some blood Parameters of Sheep

Abstract

This study was carried out to estimate the seroprevalence of brucellosis in sheep and their contact humans in addition the appearance of signs of undulant fever among some contact humans. Also, to identify the risk factors for brucellosis seropositivity at human and animal level in different regions of the Baghdad province. The study involved randomly collection of forty blood samples from 40 herds of sheep and from each blood samples, 40 (37 ewes and 3 rams) were tested for Rose-Bengal plate test (RBPT) then confirmed this diagnosis of the positive and negative samples of RBPT. The results showed there were differences in the infection rates of sheep brucellosis according to gender, four (4) rams’ sera were tested,4(100%) were positive ,36 ewes sera were tested ,14(36.8%) were positive with Rose Bengal test. According to age, the results showed that a high sera prevalence rate (70%) was at 3 years old comparison with low sera prevalence rate (40%) was mention at 4 years. Conclusions: Brucella infection in male is higher than females due to a smaller number of male companions to female, while females recorded higher infection rate. Brucella infection was recorded at age of 3years in addition 5 years. Neutrophils were higher than other mononuclear cells in WBCs count of Brucella in infected sheep
