Prevalence of Camel Brucellosis at Al-Shalateen Area

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 were detected between season and gender in the frequency of +ve and -ve samples in different tests.

Exposure to Brucella Species, Coxiella burnetii, and Trichinella Species in Recently Imported Camels from Sudan to Egypt: Possible Threats to Animal and Human Health

“…In the case of brucellosis, numerous reports advocated that when the weather condition favors the increase in the transmission rates of brucellosis in livestock, humans, wild animals, and the environment, the incidence of the disease increases significantly, and vice versa [ 28 , 62 ]. Similar findings were reported in camels from the Shalateen area, our investigated region [ 61 ]. In the same context, although C. burnetii transmission is mainly airborne, ticks may act as vectors and play an important role in the natural cycle of transmission of coxiellosis among wild vertebrates and livestock, thus seasonal fluctuations are highly expected [ 57 , 63 , 64 ].…”

“…However, our seropositive rate of Brucella spp. (3.5–5.3%) in tested male camels was similar to those demonstrated in male camels (7.1%) from the same area of our tested samples [ 61 ], and lower than those reported by Khan et al (2020) in camels from various regions in Egypt (17.6–34.9%) [ 28 ]. In the case of C. burnetii seroreactvity (4.3%), it was significantly lower than those recorded in male camel sera (17%) collected from different Egyptian regions [ 57 ].…”

“…In addition, previous studies in Sudan have not shown any bias towards the incidence of brucellosis in the eastern region of Sudan, as noticed in our study [ 8 , 29 , 59 ]. This might be attributable to insufficient preventive measures and the lack of adequate control programs as well as uncontrolled or illegal animal transportation across borders between Egypt and Sudan [ 60 , 61 ]. Notably, in both cases of Brucella spp.…”

A Novel Designed Sandwich ELISA for the Detection of Echinococcus granulosus Antigen in Camels for Diagnosis of Cystic Echinococcosis

“…Five hundred and eighty-seven (587) blood samples were collected from the camels during the veterinary medical examinations in the abattoir by restraining the camels in a laying down position (with the assistance of two camel handlers) and drawing 5 milliliters of whole blood from the jugular vein using a sterile needle [ 41 ].…”

Prevalence and Molecular Differentiation of Brucella Species ‎in Buffaloe Raw Milk and Karish Cheese in Egypt

“…Most isolates of B. melitensis were typed as biovar 3 according to the results. According to previous records, this biovar was identified and regarded as the most common kind in Egypt [2, 35,37]. Karish cheese is a soft acid cheese that is widely produced in Egypt.…”
