2021 SEROLOGICAL DETECTION OF COXIELLA BURNETII IN RAW MILK OF GOATS IN BAGHDAD, IRAQ Biochemical and Cellular Archives
Dairy domestic animals are the primary source of Coxiella burnetii for both animals as well as humans. Although, most Coxiella infections are usually asymptomatic, subclinical or mild, debilitating complications and great economic losses among small ruminants have confirmed. This study was performed to estimate the prevalence of specific IgG antibodies against C. burnetii in milk samples of lactating goats using the enzyme-linked immunosorbent assay (ELISA). In 186 milk samples collected from lactating goats in Baghdad province (Iraq) during March to April / 2021, overall 49 (26.34%) animals were seropositives. Titers of seropositives showed a significant increase (P<0.029) in moderate (63.27%) infection when compared to weak (28.57%) and severe (8.16%). Among positive and negative goats, the findings of clinical examination revealed no significant differences (P>0.05) in body temperature, pulse and respiratory rates. Regarding case history data, significant increases were identified in positive goats with abortion (38.78%), low milk production (57.14%) and in study animals housed and/or pasteurized with sheep and cattle (63.27%). Concerning the demographic risk factors, findings of age were reported a significant increase in prevalence of C. burnetii among positive goats of ³ 4 years (40.43%), when compared to ³ 2 - <4 years (22.5%) and <2 years (3.85%). For region factor, no significant differences (P£0.053) were seen between positive study goats of Al-Shu’ala (19.35%), Abu-Graib (26.44%) and Al-Nahrawan (27.94%). In conclusion, C. burnetii is relatively high in distribution among study goats and that, humans consumed milk and/or their non-pasteurized derivatives of these animals are at high risk of infection
