Clinical case report of oesophagostomiasis in captive Hamadryas Baboon (Papio Hamadryas) in Ethiopia

Oesophagostomum spp is a nodule causing nematode found in livestock and primate species in Sub-Saharan Africa. The L3 infectious larvae invade the colonic wall, forming nodules in which the larvae continue their development. It can be a serious zoonotic risk in some areas in Africa. Primates are natural hosts for the parasite and do in general not show any symptoms. We present here a clinical case of Oesophagostomiasis in a captive hamadryas baboon (Papiohamadryas) in Ethiopia who died of acute peritonitis as a result of the infection with the parasite. Post-mortem was performed and colon tissue analyzed by cytology. This case highlights the importance of Oesophagostomiasis in captive baboons that undergo stress full events and the need for adequate management.Keywords: PapioHamadryas, Oesophagostomiasis, Ethiopi

Chapitre 15 - Tuberculose bovine à l’interface homme-bétail-faune sauvage en Afrique subsaharienne

Introduction Une majorité (60 %) de maladies infectieuses est de nature zoonotique et parmi celles-ci plus des deux tiers disposent d’une espèce réservoir dans la faune sauvage (Jones et al., 2008). Les maladies qui affectent le bétail provoquent la perte de plus de 40 % de l’approvisionnement alimentaire mondial. Tout en menaçant l’économie des nations en voie de développement et la sécurité alimentaire, les maladies qui affect..

Approach to assess the economic impact of bovine tuberculosis in Ethiopia

AbstractBovine TB is prevalent in Ethiopian cattle and represents a serious zoonotic risk. However, extensive epidemiological data in the human and livestock sector are lacking. Create a dynamic transmission model of disease between animal and human, as a prerequisite for economic analysis of the most profitable intervention to control BTB in Ethiopia. Study on-going (2005-2010), epidemiological (prevalence, risk factors) and cost (human and livestock) data are collected in eight sites over a period of four years and fed into a compartmental trans-sectoral framework that simulates disease transmission. Different intervention scenarios will then be simulated in the model. The most profitable intervention to control BTB in Ethiopia has to be assessed as well as the cost sharing scheme between the public health and agricultural sectors. It has been postulated that a test and slaughter policy would have a negative economic impact in Ethiopia. Alternatives need to be assessed. [Ethiop.J.Health Dev. 2008;22(Special Issue):135-13

Mycobacterium tuberculosis in a Primagam negative wild caught captive olive baboon (Papio anubis) in Ethiopia

A free-roaming wild olive baboon (Papio anubis) was caught in the compound of a hospital and kept in captivity pending reintroduction to the wild. The animal had a sporadic dry cough but was TB negative on the blood-based assay PRIMAGAM (IFN-γ test). Six years later, the animal was found dead without any prior clinical signs. The lungs were severely affected. Laboratory analysis included Ziehl-Neelsen staining, GenExpert, culture, deletion typing and spoligotyping. M. tuberculosis was isolated. The spoligotype was SIT 53 (lineage 4) and no Rifampicin resistance was detected. This case report raised challenges on accurate diagnosis of TB in Non-Human Primates in Ethiopia, the question of latency in baboon and the lack of spread of a highly virulent TB strain in the Non-Human Primate colony. It also highlighted the potential role of TB transmission between Non-Human Primates and people in Ethiopia with impacts as well on public health as on primate conservation.

Bovine tuberculosis and brucellosis prevalence in cattle from selected milk cooperatives in Arsi zone, Oromia region, Ethiopia

Bovine tuberculosis (BTB) and bovine brucellosis are two important milk-borne zoonoses that have been shown to be prevalent to various degrees in Ethiopian cattle. The study was carried out in four Woredas (districts) around Asella town, Arsi Zone between October 2011 and March 2012 and included 318 small-holders in 13 dairy cooperatives that marketed the delivered milk. The aims of the study were i) to assess the prevalence of the two diseases in cattle in a cross-sectional study, ii) to assess potential risk factors of BTB and brucellosis to humans as well as the knowledge-attitude-practice (KAP) among these farmers towards these diseases.; BTB testing using the comparative intradermal skin test (CIDT) was done on 584 milking cows, out of which 417 were serologically tested for brucellosis using the Rose Bengal Plate Test and reactors confirmed with an indirect ELISA test (PrioCHECK®). The individual animal prevalence was 0.3% (95% CI 0.1% to 1.3%) for BTB, 1.7% (95% CI 0.8% to 3.5%) for brucellosis and 8.9% (95% CI 6.8% to 11.5%) for MAC (Mycobacterium avium complex). Of the 13 milk cooperatives, two had at least one positive BTB reactor and five had animals positive for brucellosis. Cross-breeds accounted for 100% and 71.4% of the BTB and brucellosis reactors respectively. For both diseases, there were prevalence variations depending on Woreda. No animal was concomitant reactor for BTB and brucellosis. Raw milk was consumed by 55.4% of the respondents. 79.2% of the respondents reported touching the afterbirth with bare hands. The latter was fed to dogs in 83% of the households. One cow among the herds of the 130 interviewees had aborted in the last 12 months. Among the interviewees, 77% stated knowing tuberculosis in general but 42 out of the 130 respondents (32.3%) did not know that BTB was transmitted by livestock. Less than half (47.7%) of the respondents knew about brucellosis.; Low prevalence of both diseases reflected the potential for the area to compete with the growing milk demand. The authors discussed the possible control strategies for the area

A Longitudinal Study of Cattle Productivity in Intensive Dairy Farms in Central Ethiopia.

Ethiopia is witnessing an emergence of intensive urban dairy farming. The aims of this study were to capture cattle productivity parameters in selected intensive dairy farms in and around Addis Ababa (Central Ethiopia). The study is a pre-requisite and baseline for further economic analysis of diseases such as bovine tuberculosis (BTB) and to assess some of the current challenges faced by farm owners for optimal animal performances. Hence, a 3-year longitudinal observational study was conducted for the first time in Ethiopia, in 24 dairy farms with intensive husbandry, including a total of 1,705 dairy animals. Herd characteristics, animal movement, and productivity parameters (fertility, morbidity, mortality) were recorded in a herd-book. Whereas, half the farms saw their animals increase in number over the 3 years, 37.5% (mainly large farms) saw their herd size decrease. Offtakes accounted for 76.6% of all animal exits. One hundred and ninety (11.1%) animals died of natural causes. Highest mortality was observed in young stock (13.9%). Overall, diseases were the leading cause for death (57.5%). The majority of calves (69%) that died, did so within the first week of life. Mean calving interval (CI) was 483.2 days. Successful conception after artificial insemination (AI) was 66.1% with Addis Ababa and smaller farms faring worst. Mean time interval from calving to first service was 152 days. Date of birth to first service was 592.2 days and date of birth to first calving was 794.7 days. In conclusion, the study showed sub-optimal productivity performances in intensive dairy cattle and highlighted some of the current gaps and challenges in urban dairy productivity

‘I Could Not Bear It’. Perceptions of Chronic Pain among Somali Pastoralists in Ethiopia. A Qualitative Study

Background Pain is a major public health problem in the Global South, particularly among marginalized communities, such as Somali pastoralists. Yet, the topic of chronic pain has not yet been comprehensively studied in Sub-Saharan Africa, specifically in the Somali region of Ethiopia. Therefore, this study aims to explore the perceptions and notions of chronic pain among Somali pastoralists in this context. Methods This study used an explorative qualitative design. We performed semi-structured, face-to-face interviews with 20 purposively selected female and male Somali pastoralists with chronic pain. For data analysis, we applied the Framework Method by Gale et al. and explained patterns drawing on the Enactive Approach to Pain proposed by Stilwell and Harman. Findings Six different themes emerged: (1) “Pain as a symptom of harsh daily life”, (2) “Pain descriptions and dimensions”, (3) “Temporality of pain”, (4) “Pain-related stigma and stoicism” (5) “Mediating role of spirituality”, and (6) “Impact of pain on daily life activities”. Conclusions Somali pastoralists described their chronic pain as a multicausal and relational experience. Pastoralists (especially women) commonly refrained from communicating their pain and represented aspects of social stigma and stoicism. The mediating role of spirituality aided pastoralists to make sense of their pain and to ease its impact on their harsh daily life. The findings of this study can contribute to raise awareness of chronic pain issues among pastoralists. They highlight the need for policymakers to prioritize the improvement of pastoralist-specific pain management. Necessary resources and skills should be available within health care facilities. Pain management should be accessible, affordable and culturally acceptable for this population

Effect of Bovine Tuberculosis on Selected Productivity Parameters and Trading in Dairy Cattle Kept Under Intensive Husbandry in Central Ethiopia.

Bovine tuberculosis (BTB) has substantial impact on fertility, milk, and meat productivity in cattle. However, these assumptions are based on outdated data. Recent global studies on the impact of BTB on cattle productivity are scarce and show sometimes inconclusive and/or contradicting results. This pilot study is the first longitudinal study performed in urban upgraded dairy cattle in Ethiopia that are kept under intensive husbandry. We assessed whether BTB has an impact on various animal productivity parameters and animal movement. Animals (N = 890) included in the study were tested for BTB at least once using the comparative intradermal tuberculin test (CIDT). Fertility, mortality, and offtake were assessed in 21 dairy farms where herd follow-ups over 3 years were performed. In addition, an independent abattoir survey was conducted to assess carcass weight and visible TB-like lesions upon meat inspection. Animal movements (purchasing and offtakes) were documented for each farm. The impact of BTB status on the intervals been birth, service, and calving times and the intercalving intervals was analyzed using a Cox proportional hazards model. The hazard ratio associated with BTB-positive animals was smaller than 1 for all fertility parameters, suggesting that BTB status increases the time between events; however, the effect was small and only statistically significant (95% level) for the time between calving and service. Offtakes included a higher percentage of reactor animals (58%) as compared with non-reactor animals (42%) (p = 0.0001). Overall, reactors were eliminated from the farms within 238.6 days after receiving test results, which was 54.9 days faster than for negative animals. The majority of owners purchased animals within their town or its surrounding. Nearly a quarter of reactors were sold directly to other farms. Animals were also sold further away, including other regions, raising the question of disease spread and the need for an animal tracing mechanism. In the abattoir survey, a total of 349 carcasses were weighed, of which 8% showed visible TB-like lesions and 53.6% had fasciolosis. Negative adult bull carcasses were 7.5 kg heavier than reactor bulls.This work was funded by the Biotechnology and Biological Sciences Research Council, the Department for International Development, the Economic and Social Research Council, the Medical Research Council, the Natural Environment Research Council, and the Defence Science and Technology Laboratory, under the Zoonoses and Emerging Livestock Systems (ZELS) programme, ref.

Nutritional status and intestinal parasites among young children from pastoralist communities of the Ethiopian Somali region

Pastoralist children in the Ethiopian Somali Regional State (ESRS) are at high risk for undernutrition and intestinal parasitic infections (IPIs). We assessed the nutritional status and its association with IPIs in 500 children <5 years of age in a clustered cross-sectional study in Adadle district, ESRS. Stool samples were microscopically examined for IPIs and biomarkers for iron and vitamin A status, anthropometry, and food variety score (FVS) were assessed. Median (interquartile range [IQR]) FVS was 2.0 (2.0, 4.0), and 35% of children were exclusively breastfed up to age 6 months. Prevalence of stunting, wasting, underweight and mid-upper arm circumference (MUAC) <12.5 cm was 30, 34, 40, and 16%, respectively. Median (IQR) haemoglobin, ferritin, and retinol-binding protein concentrations were 9.5 g dL; -1; (8.2, 10.9), 6.2 μg L; -1; (4.0, 10.2), and 0.8 μmol L; -1; (0.67, 0.91), respectively. Prevalence of anaemia, iron, and vitamin A deficiency was 75, 91, and 30%, respectively. IPIs' prevalence was 47%; the most prevalent IPIs were Giardia lamblia (22%) and Ascaris lumbricoides (15%). Giardial infections but not A. lumbricoides increased the risk for MUAC 2 or with exclusive breastfeeding up to 6 months, respectively. Undernutrition and IPIs are alarmingly high in <5 years of age children in ESRS. Giardial infections and low nutritional adequacy of the diet seem to be major contributing factors to the precarious nutritional status and should be addressed by appropriate interventions

Determinants of patient delay in diagnosis of pulmonary tuberculosis in somali pastoralist setting of Ethiopia : a matched case-control study

Background; : Healthcare-seeking behavior is the basis to ensure early diagnosis and treatment of tuberculosis (TB) in settings where most cases are diagnosed upon self-presentation to health facilities. Yet, many patients seek delayed healthcare. Thus, we aimed to identify the determinants of patient delay in diagnosis of pulmonary TB in Somali pastoralist area, Ethiopia.; Methods; : A matched case-control study was conducted between December 2017 and October 2018. Cases were self-presented and newly diagnosed pulmonary TB patients aged ≥ 15 years who delayed &gt; 30 days without healthcare provider consultation, and controls were patients with similar inclusion criteria but who consulted a healthcare provider within 30 days of illness; 216 cases sex-matched with 226 controls were interviewed using a pre-tested questionnaire. Hierarchical analysis was done using conditional logistic regression.; Results; : After multilevel analysis, pastoralism, rural residence, poor knowledge of TB symptoms and expectation of self-healing were individual-related determinants. Mild-disease and manifesting a single symptom were disease-related, and &gt;1 h walking distance to nearest facility and care-seeking from traditional/religious healers were health system-related determinants of patient delay &gt; 30 days [; p; &lt; 0.05].; Conclusion; : Expansion of TB services, mobile screening services, and arming community figures to identify and link presumptive cases can be effective strategies to improve case detection in pastoral settings
