“…The current study also revealed that cows with a prior history of abortion had higher odds of Brucella seropositivity (OR: 2.8, 95% CI: 1.6 – 4.7, p: <0.001). Our finding is in agreement with a previous study conducted in South Sudan [17]as well as with the findings from multiple studies[37–40] which reported an association of Brucella seropositivity with abortion.…”

“…The study revealed that, older cattle over two years of age (OR: 3.5, 95% CI: 1.2 – 10.3-, p: 0.025) had higher odds of Brucella seropositivity than younger ones. This finding is in agreement with several studies [37,38] that also identified age as a risk factor for Brucella seropositivity in cattle. In contrast to the current’s study finding, another study had revealed a higher odds of Brucella infection in young compared to adults [41].…”

Author summary Brucellosis is a neglected, bacterial zoonotic disease that is caused by several species of the genus Brucella. Cross-species transmission of Brucella can occur in mixed or integrated farming systems. The disease poses serious public health implications and substantial economic losses particularly in low-income countries including South Sudan. This study was conducted to estimate the seroprevalence of brucellosis in pastoralists, their livestock as well identifying potential risk factors associated with Brucella infection. Knowledge of the seroprevalence of brucellosis and risk factors is a prerequisite towards planning an effective mitigation strategy of the disease. The study revealed high seroprevalence of brucellosis in cattle compared to goats, and the following risk factors were identified; prior history of abortion, age (old) and sex (female) significantly associated with Brucella infection. Surprisingly, sheep were found to be seronegative.

“…This is in agreement with the findings by Traoré et al ( 29 ) who reported 6.9 and 4.8%, respecively. However, this is inconsistent with the study by Rob et al ( 30 ) who reported 19.35% in smaller and 6.45% in larger herds. This variation in the prevalence could be attributed to an increase in stock density in large herd sizes, which facilitates transmission of Brucella spp.…”

Brucellosis is a neglected bacterial zoonotic disease with economic and public health importance in pastoral communities of sub-Saharan Africa. A cross-sectional study was conducted from December 2021 to April 2022, to estimate the prevalence and identify the associated risk factors causing brucellosis in animals and associated with occupational diseases in humans from three selected districts of “the Somali Pastoral region,” Eastern Ethiopia. In this study, 1,000 serum samples were screened for anti-Brucella spp. antibodies using Rose Bengal Plate Test (RBPT) and further confirmed using a competitive enzyme-linked immunosorbent assay (cELISA). A structured questionnaire was used to collect the biodata of tested animals and animal attendants to test the association between explanatory and outcome variables. The overall animal level prevalence was 5% (95% CI, 6.1–7.2.0) in small ruminants, 2.9% (95% CI, 1.5–4.9) in camels, and 2.0% (95% CI, 0.2–3.7) in occupationally linked humans. Herd size and herd history of retained fetal membranes were risk factors associated with Brucella spp. seropositivity in animals (p < 0.05). Disposing of retained fetal membranes was significantly associated (p < 0.05) with Brucella spp. seropositivity in humans. Evidence of brucellosis in various livestock species and associated seropositivity in humans indicates the need for a coordinated One Health approach, considering sociocultural dynamics of pastoral communities in controlling brucellosis to safe guard public health and increase livestock productivity.

“…In addition, in many of these 34 studies, a random selection of animals included the epidemiologically irrelevant young ones, thus reducing the probability of detecting infected herds/flocks. One or more of these problems are also common in more recent works, thus limiting the value of the studies [ 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 ].…”

One Health is the collaborative efforts of multiple disciplines to attain optimal health for people, animals and the environment, a concept that historically owes much to the study of brucellosis, including recent political and ethical considerations. Brucellosis One Health actors include Public Health and Veterinary Services, microbiologists, medical and veterinary practitioners and breeders. Brucellosis awareness, and the correct use of diagnostic, epidemiological and prophylactic tools is essential. In brucellosis, One Health implementation faces inherited and new challenges, some aggravated by global warming and the intensification of breeding to meet growing food demands. In endemic scenarios, disease awareness, stakeholder sensitization/engagement and the need to build breeder trust are unresolved issues, all made difficult by the protean characteristics of this zoonosis. Extended infrastructural weaknesses, often accentuated by geography and climate, are critically important. Capacity-building faces misconceptions derived from an uncritical adoption of control/eradication strategies applied in countries with suitable means, and requires additional reference laboratories in endemic areas. Challenges for One Health implementation includee the lack if research in species other than cattle and small ruminants, the need for a safer small ruminant vaccine, the need to fill in the infrastructure gap, the need for realistic capacity-building, the creation of reference laboratories in critical areas, and the stepwise implementation of measures not directly transposed from the so-called developed countries.
