Abstract
Sera of 801 apparently healthy dromedary camels were collected from Al-Shalateen quarantine and tested by BAPAT, RBPT and there results were confirmed by CFT. The results revealed that the prevalence of camel brucellosis was 12.9%, 11.6% and 11.5% for BAPAT, RBPT and CFT respectively. Also results revealed that seroprevalence was higher in camels younger than 2 years (immature) (13.3%) than mature camels (2-4 years old) (10.6%) and camels at breeding age (older than 4 years) (10.8%). In addition, prevalence on females (19.1%) were higher than males (7.1%). Moreover, Brucella melitensis biovar 3 was isolated from stomach content of aborted camel fetus. Statistical analysis of these results revealed that the apparent prevalence (AP) was estimated as (11.5%) while true prevalence (TP) was estimated as (13.6%) (95%CI: 11.2-16%). There is no significant difference were detected between different age groups while a highly significant difference was detected among season and gender in the frequency of +ve and –ve samples in different tests.
