“…Camels are not known to be primary hosts of Brucella organisms, but they are susceptible to both Brucella abortus and Brucella melitensis (Abbas and Agab, 2002;Cooper, 1991;Gwida et al, 2012;Seifert, 1996). In pregnant camels, the bacteria localize in the placenta and are most abundant in abortion material (up to 10 13 ) including the fetal stomach, vaginal discharge and colostrum (Millar and Stack, 2012).…”

| The present study was delineated for investigation of the seroprevalence of brucellosis in camels and characterization of the causative Brucellae affecting camels in Egypt on bacteriological and molecular basis. A serological study using 1126 blood samples collected from Dromedary camels was carried out. The modified Rose Bengal Plate Test (mRBPT) and competitive ELISA (cELISA) were used as screening and confirmatory tests, respectively. The overall sero-prevalence of Brucella antibodies was 4.17% and 3.73% as detected by the mRBPT and c-ELISA respectively. Lymph nodes, testicular tissues, udder tissues and milk from seropositive positive camels were used for isolation of Brucella organisms. Brucella melitensis biovar 3 was isolated from milk of two she-camels. The bacteriological findings suggested that camels were infected from cattle or sheep and goats where Brucella melitensis biovar 3 is prevalent among large and small ruminants in Egypt. The mRBPT was suitable for screening camel sera for brucellosis, but the cELISA was more specific. It is likely that the tendency to raise large flocks of sheep along with the camels in Egypt contributed towards Brucella melitensis infection among camels. DNA extracts of two Brucella melitensis positive milk samples were tested using conventional and Bruce ladder multiplex PCR. Three fragments of 587 bp, 1071 bp and 1682 bp sizes were amplified using multiplex Bruce ladder PCR confirming the bacteriological findings.

“…However, despite its economic importance in nomadic herds, camel brucellosis appears to be overlooked (21). Camels are known to be primarily infected by B. abortus or B. melitensis and to act as silent carriers of brucellosis (22). Therefore, more strict control and prevention programs for livestock, including camels, are required to minimize economic losses in Mongolia.…”

“…Brucellosis was reported in camels as early as 1931 (Solonitsuin, 1949); since then, the disease has been reported from all camel-keeping countries (Gwida et al, 2012). Camels are frequently infected with Brucella organisms, especially when they are in contact with infected large and small ruminants (FAO/WHO, 1986;Radwan et al, 1992).…”
