“…The true prevalence of 4.1% recorded in the present study agrees with the results recorded by Teshome et al (2003) in Borena with a prevalence of 4.2% and in the Afar with a prevalence of 4.1% [6,21]. However, the result of this study was higher than the observation recorded by Mohammed et al (2011) in Dire Dawa (1.6%), Tilahun et al, 2013 in Jijiga and Babile districts, Eastern Ethiopia (2.43%) and Zeru et al (2016) in the Afar (2.09%) [23,25,26]. Our study result was noted to be lower than the observation by Zewolda and Wereta (2012) and Sisay and Mekonnen (2012) who reported a prevalence of 5.7% and 7.6%, respectively in different districts of Afar region [22,27].…”

Brucellosis is a highly infectious bacterial disease of global significance, which affects humans as well as a wide variety of animals. A cross-sectional study was conducted in three selected districts of Afar region of Ethiopia to determine the seroprevalence of camel brucellosis. A total of 245 camels from selected districts were included in the study. All serum samples were tested and screened serologically using Rose Bengal plate test and confirmed using a complement fixation test. Associated risk factor analysis was also conducted using chi-square and logistic regression analysis. As a result, 30 (12.2%) were Rose Bengal plate test reactors in which 10 (4.1%) were confirmed to be positive using complement fixation test. The statistical analysis indicated that herd size (χ2=13.206; p=0.001 and OR=17.053; 95% CI=1.988-146.254), contact with other ruminants (χ2=13.524; p=0.00 and OR=12.774; 95% CI=1.560-104.625) and history of abortion (χ2=28.022; p=0.00 and OR=38.000; 95% CI=4.694-307.657) were statistically significant and the major risk factors for the presence and transmission of the disease between animals. But age, body condition score, physiological status, parity and geographical location were found statistically insignificant (P>0.05). Public awareness towards the diseases was interviewed with the structured questionnaire format and it was noted that most of the pastoralists had no knowledge about zoonotic disease transmission, consequences of consuming raw milk, and handling aborted animals without any protective material. In general, camel brucellosis is prevalent in this area of study and public awareness towards zoonotic importance is low. Therefore, fruitful and sustainable work is required from the government, animal health professionals, and other stakeholders in the prevention and control of the disease. Improved public awareness is inevitable to reduce the prevalence and spread of the camel brucellosis.

“…In the present study, 1.5% of herds had seropositive animals. Few studies have reported herd-level prevalence in camels (Radwan et al ., 1992; Omer et al ., 2000; Megersa et al ., 2005; Al-Majali et al ., 2008; Mohammed et al ., 2011); however, the majority of these were not truly representative of the population and targeted specific high-risk components of the population, and hence reported higher values (10.2%–54.2%). A low herd-level seroprevalence (<2%) was observed in this study as compared to previous estimates (3.5%) in Oman (Ismaily et al ., 1988).…”

“…Since the sampling plan was constituted to detect at least a single animal positive with the expected prevalence to be 50%, a low-level individual seroprevalence (0.4%) was recorded during the study. Individual camel seroprevalence ranging from 1.6% to 12.1% have been reported in other studies (Radwan et al ., 1992; Kudi et al ., 1997; Abou-Eisha, 2000; Omer et al ., 2000; Megersa et al ., 2005; Al-Majali et al ., 2008; Dawood, 2008; Balcha and Fentie, 2011; Mohammed et al ., 2011). Low-level individual prevalence ranging from 1.4% to 2.0% was reported by the studies from Saudi Arabia, Iran, Abu Dhabi, Egypt, Ethiopia, and Somalia (Baumann and Zessin, 1992; Afzal and Sakkir, 1994; Khadjeh et al ., 1999; Abou-Eisha, 2000; Megersa et al ., 2005; Mohammed et al ., 2011).…”

Brucellosis is a globally distributed and economically devastating zoonotic disease of multiple species, including camels. Human and livestock brucellosis is prevalent in Oman, especially in southern Dhofar governorates of Oman, where camels share habitat and have close contact with other susceptible species. We conducted a randomized cross-sectional sero-epidemiological study to investigate the seroprevalence of brucellosis in camels of Oman. The sera from 2,250 camels from 552 geographically marked farms were screened through Rose Bengal plate agglutination test and later confirmed by the competitive ELISA (COMPLIZA, VLA, UK). In total, nine [0.4%, confidence interval (CI) 0.4, 0.8] camels from eight (1.5%, CI 0.6, 2.8) herds were tested positive for brucellosis. The highest prevalence was recorded in Dhofar (3.7%, CI 1.4, 7.9) and the lowest in Sharqiyah (1.3%, CI 0.0, 7.2) governorate ( p = 0.052). All seropositive camels were of local breed and females. Seroprevalence was higher (0.5%, CI 0.2, 1.0) in adults (>4 yr of age) as compared with young (≤4 yr of age) camels (0.2%, CI 0.0, 0.8). The results of binary logistic regression indicated that camel herds located in south (Dhofar) [odds ratio (OR) 6.39, CI 1.01, 40.67], practice of open replacement system (OR 14.49, CI 1.83, 114.51) and with history of abortions (OR 8.01, CI 1.34, 47.77) were more likely to test positive for brucellosis. We conclude that brucellosis is endemic at a low level in camels of Oman and a control strategy based upon test-and-slaughter/inclusion of camels in the current vaccination program after carefully planned vaccine evaluation studies could be considered to control it.

“…In the other hand, Despite the advances made in surveillance and control, the prevalence of brucellosis is increasing in many developing countries due to various sanitary, socioeconomic, and political factors [37]. In extensive management system the prevalence of brucellosis among various species of animal is low [30].…”

ABSTRACT. Advances in molecular sciences allow us to make extensive use of 15 equipment in order to meet needs. In this present study to overcome the shortcomings of respectively. Beside, the results of real-time PCR showed that 3.56% and 2.27% of bovine 27 and 2.6% and 1.87% of buffalo semen samples were infected with unknown species and 28 both species, respectively. The sensitivity and specificity of conventional PCR were 29 obtained 100% and 98.17% in bovine and 100% and 98.56% in buffalo semen samples. 30The CT values had significant differences (p<0.05) between the incidences of both 31Brucella abortus and Brucella melitensis in bovine with buffalo semen samples.
