“…BTB prevalence between 2014 and 2016 was 6.7%. This was similar to previous studies conducted in Nigeria (Ejeh et al, 2014;Okeke et al, 2016), Pakistan (Memon et al, 2018), Sicily, Southern Italy that cattle organs and/or carcass condemnation were associated with hydatidosis, cysticercosis, fasciolosis, and BTB (Mellau et al, 2011;Tembo and Nonga, 2015), though with lower levels of occurrences except fascioliosis when compared with our study. In our study, abattoir data showed that organ condemnations (both partial and total) were based on lesions observed at postmortem by certified veterinarians.…”

Slaughterhouses are certified premises where animals are slaughtered and inspected to ensure meats are wholesome and safe for public consumption. To determine the common zoonoses encountered in a municipal slaughterhouse of Abeokuta, Ogun State, Nigeria, a three-year retrospective study was conducted (2014–2016). During the review of slaughterhouse records, the overall throughput of cattle slaughtered was 146,794 (4077.6 ± 413.6; 95% confidence interval [CI] 3923.3–4206.7). Female animal slaughtering outweighed male ones at 5:1 ratio (p < 0.0001). The highest number of cattle were slaughtered in December 2014, December 2015, and August 2016. Of all the total cattle slaughtered, the overall observed prevalences for bovine tuberculosis (BTB), hydatidosis and fasciolosis were estimated as 9514 (6.5%, 264.3 ± 81.7; 95% CI 236.6–291.9), 1851 (1.3%, 55.8 ± 17.3; 95% CI 49.9–61.6) and 845 (0.6%, median = 19.0; 95% CI 18.7–28.3), respectively. On average the highest number of BTB cases was reported in February-March, it declined slightly in October and increased again in November. Similarly, the highest numbers of hydatidosis and fasciolosis were observed in March and February, respectively. A significant (p = 0.02) mean variation of cases of BTB was found across the period and it was higher (p = 0.03) during the wet/rainy season in 2015. Our results emphasized the need to promote coordinated active surveillance for zoonoses detection and mitigation to ensure food safety at farm and slaughterhouse levels. Adequate record keeping for specific organ/meat/carcass condemnation is crucial at postmortem, as this represents a significant loss of animal proteins and revenues. Such data can be used for informed policy to intensify reduction in economic loss associated with animal diseases.

“…In a study conducted in a slaughterhouse in Nigeria, tuberculosis showed a cyclical behavior (seasonality), with greater occurrence in July and August, differing from the result found in the present study. The authors related this seasonality to stressful factors that occur in this period (off-season) and the increase in the number of religious slaughters (Okeke et al 2016). The absence of seasonal influence on the occurrence of tuberculosis, observed in the present study, can be explained by the variables, such as: incubation period of the microbiological agent and chronic character of the disease.…”

Epidemiological analysis of bovine tuberculosis in the southern region of Rio Grande do Sul from 2000 to 2015

Bovine tuberculosis (BTB) is an infectious and zoonotic disease with socioeconomic importance, responsible for economic losses in livestock due to the decrease in animal productivity, mortality, bovine carcass condemnation and restriction on exportations. The objective of the present study was to evaluate the epidemiological aspects of this disease through a descriptive analysis and time series of cases of bovine tuberculosis diagnosed at the Laboratório Regional de Diagnóstico (LRD) of the Faculdade de Medicina Veterinária, Universidade Federal de Pelotas (UFPel) from 2000 to 2015. A survey was carried out in the LRD database of cases diagnosed as tuberculosis in cattle during this period. The incidence rate of BTB ([cases/population] x 100000) was calculated. Qualitative variables (sex, age, race, origin, type of material and presumptive diagnosis) were analyzed in a descriptive way, aiming to establish the profile of affected animals, characterize the municipalities in which the disease is originated and also fix the main referral organs for diagnosis. The time series analysis was performed using the Gretl statistical software 1.9.12 (GNU Regression, Econometric and Time-series Library). To verify the existence of the stationary distribution, the test of Dickey-Fuller was used, considering a value of p<0.05. During this period, 331 cases of BTB were diagnosed in the LRD. The present study identified that the predominant profile of the bovines affected by tuberculosis was female bovine aged more than two years old and crossbreed; the main organ sent for histopathological examination was lymph nodes. The microregion of Pelotas presented the highest incidence of the disease. There was also a tendency of a decrease in the incidence rate of this disease over the years, absence of seasonal influence in the occurrence of the disease and no cases of epidemics occurred from 2002 to 2015 in the area covered by the LRD-UFPel.

Systematic Review of Important Bacterial Zoonoses in Africa in the Last Decade in Light of the ‘One Health’ Concept

2019

Zoonoses present a major public health threat and are estimated to account for a substantial part of the infectious disease burden in low-income countries. The severity of zoonotic diseases is compounded by factors such as poverty, living in close contact with livestock and wildlife, immunosuppression as well as coinfection with other diseases. The interconnections between humans, animals and the environment are essential to understand the spread and subsequent containment of zoonoses. We searched three scientific databases for articles relevant to the epidemiology of bacterial zoonoses/zoonotic bacterial pathogens, including disease prevalence and control measures in humans and multiple animal species, in various African countries within the period from 2008 to 2018. The review identified 1966 articles, of which 58 studies in 29 countries met the quality criteria for data extraction. The prevalence of brucellosis, leptospirosis, Q fever ranged from 0–40%, 1.1–24% and 0.9–28.2%, respectively, depending on geographical location and even higher in suspected outbreak cases. Risk factors for human zoonotic infection included exposure to livestock and animal slaughters. Dietary factors linked with seropositivity were found to include consumption of raw milk and locally fermented milk products. It was found that zoonoses such as leptospirosis, brucellosis, Q fever and rickettsiosis among others are frequently under/misdiagnosed in febrile patients seeking treatment at healthcare centres, leading to overdiagnoses of more familiar febrile conditions such as malaria and typhoid fever. The interactions at the human–animal interface contribute substantially to zoonotic infections. Seroprevalence of the various zoonoses varies by geographic location and species. There is a need to build laboratory capacity and effective surveillance processes for timely and effective detection and control of zoonoses in Africa. A multifaceted ‘One Health’ approach to tackle zoonoses is critical in the fight against zoonotic diseases. The impacts of zoonoses include: (1) Humans are always in contact with animals including livestock and zoonoses are causing serious life-threatening infections in humans. Almost 75% of the recent major global disease outbreaks have a zoonotic origin. (2) Zoonoses are a global health challenge represented either by well-known or newly emerging zoonotic diseases. (3) Zoonoses are caused by all-known cellular (bacteria, fungi and parasites) and noncellular (viruses or prions) pathogens. (4) There are limited data on zoonotic diseases from Africa. The fact that human health and animal health are inextricably linked, global coordinated and well-established interdisciplinary research efforts are essential to successfully fight and reduce the health burden due to zoonoses. This critically requires integrated data from both humans and animals on zoonotic diseases.
