“…The present study was following the previous investigations of 29 , 34 those who reported that seroprevalence of ovine brucellosis was significantly different among the flock size categories (small, medium and large) and seroprevalence increases with flock size in Ethiopia. Another previous study was also evidenced that lower seroprevalence in small flocks compared to medium-sized and large-sized flocks 35 from other countries elsewhere.…”

Background Brucellosis is a zoonotic disease with economic and public health significance in developing countries that rely on livestock production including Ethiopia. This study intended to establish the seroprevalence and associated risk factors of ovine brucellosis. Methods A cross-sectional study was carried out on seroepidemiology of ovine brucellosis from January 2017 to June 2020 G.C in five districts of South Omo zone, Southern Ethiopia. A total of 1536 sera samples were collected from sheep and serially tested using modified Rose Bengal plate test, competitive enzyme-linked immunosorbent assay, and complement fixation test to detect antibodies against natural infection by Brucella species. A structured questionnaire was used to collect data from individual animals, and flocks for the analysis of the association between expounding and outcome variables. Data were analyzed using STATA version 14.0 and potential risk factors for seropositivity of brucellosis were analyzed using logistic regression. Results The study discovered an overall 5.40% (95% CI: 6.34, 14.25) and 39.74% (95% CI: 6.50, 6.97) seroprevalence of ovine brucellosis at individual and flock level, respectively, by a confirmatory test. Age groups, sex, flock size, district, history of abortion, and body condition were significantly associated risk factors with Brucella seropositivity (p < 0.05). Conclusion To conclude, the prevalence of ovine brucellosis in the South Omo Zone was relatively high which needs integrated intervention approaches in place to curb the spread of the disease.

“…In the present study, the overall flock and individual sero-prevalence of T. gondii infection (92.7% and 45.3%) were higher than that (70.5% and 31.6%) reported in Ethiopia [24]. In this study, the sero-prevalence of T. gondii infection in dairy cattle at herd and individual level (95.5% and 40.9) were found to be higher than that (87.5% and 7.8%) of French beef cattle [25].…”

Abstract:Toxoplasmosis is an important cause of reproductive failure in man and farm animals resulting in significant socio-economic losses worldwide. The aim of this study was to avail large scale data-regarding the sero-prevalence of T. gondii infection in dairy animals from the Khartoum State, Sudan using the commercially available Latex Agglutination Diagnostic kits. The study revealed that the overall seroprevalence of T. gondii infection at herd level of dairy animals in the State was 92.7%. The within herd seroprevalence was ranging from 8% up to 100% with mean of 51.3% in different herds of different dairy animals species in the State. Only 6 herds, 3 herds, 3 herds and 1 herd of cattle, camel sheep and goat respectively were found to be clean from anti-T. gondii antibody in the present study. Interestingly, most of the clean herds (12 herds) are located in the Khartoum district. The differences between the three districts, the seven localities and the four animal species were statistically highly significant (P < 0.01). The overall sero-prevalence of T. gondii infection in dairy animals-at individual level-was 45.3%. Sheep scored the highest seroprevalence rate (75.0%) followed by goats (64.0%), camels (54.1%) and cattle (40.9%) with high statistically significant differences (P < 0.01). The highest level of antibody titration was reported in sheep and goats. This is the first area-wide and large scale report on seroprevalence of T. gondii infection in dairy animals from the Sudan. It was concluded that dairy animals in the Sudan are widely exposed to T. gondii and people in the Sudan should be aware of the possibility of hyper-prevalence of human toxoplasmosis through these food animals. Research on clinical toxoplasmosis in dairy animals and human in the Sudan is recommended to evaluate the role T. gondii infection in economical losses in dairy farm industry and for building strategy of sustainable toxoplasmosis control.

“…It is important to identify the actual causes in the aborting sheep and goats and/ or in the aborted fetus or placental tissues to confirm the pathogen is accountable for abortion (Morris et al, 2018). This result is in line with the reports of Gebremedhin (2015) and Wubishet et al (2017), who reported that the risk of Brucella seropositivity was not associated with abortion. However, this result is inconsistent with some previous studies in Ethiopia (Tassew and Kassahun, 2014;Asmare et al, 2013) that stated brucellosis was associated with abortion in sheep and goats.…”

The occurrence of brucellosis in different species of livestock has been reported from different parts of Ethiopia, however, the serostatus and risk factors of this disease in small ruminants is not well documented in southwestern parts of the country. This study was conducted from October 2016 to October 2017 to investigate the seroprevalence and associated risk factors of brucellosis as well as its association with abortion in sheep and goats in selected districts of Jimma zone. A total of 804 small ruminants (402 sheep and 402 goats) were randomly selected and blood samples were collected for serological tests. The presence of antibody to Brucella was screened by Rose Bengal Plate Test and confirmed using the complement fixation test. Seroprevalence of 4.2% in sheep and 5.2% in goats was recorded in this study. An overall seroprevalence of 4.7% was recorded in small ruminants in the study areas. Brucella seropositivity was observed more frequently among sheep and goats with a history of abortion (6.7%) than animals that have no history of abortion (3.7%), however, the difference noted was not statistically significant. Older age (OR 3.9, CI = 1.43-9.94), pregnancy (OR 2.6, CI = 1.19-5.72), late term gestation (OR 2.4, CI = 1.54-3.78), mixed flock (OR 2.8, CI = 1.33-5.89) and larger flock size (OR 2.7, CI = 1.08-6.95) were noted to have more number of reactors. Hence, it is important to consider brucellosis as one of the diseases that needs attention and further study should be conducted to identify the circulating Brucella species and other causes of abortion in sheep and goats. Besides, this finding warrants the need for further investigation on its public health impact in the region. Keywords: Brucellosis; Epidemiology; Sheep; Goat; Jimma Zone
