“…Javed et al (2010) have reported a prevalence of 2.4% in goats at farms using tuberculin test from Pakistan. The relatively high abattoir prevalence of caprine TB in this study and its increasing report from different parts of the world specially where bovine TB had been controlled (Michel et al 2010;Sharpe et al 2010;Quintas et al 2010) suggests that caprine TB is becoming an emerging public health problem.…”

Tuberculosis (TB) is an important zoonosis affecting a wide range of hosts. An abattoir study was conducted on 1,536 randomly selected male goats slaughtered at Modjo Modern Export Abattoir to determine the prevalence of tuberculosis in slaughtered goats. Carcasses and organs of all the study animals were first examined by routine meat inspection followed by detailed meat inspection. Samples from tuberculous lesions were cultured for mycobacterial isolation and identification. Histopathology was done on 31 samples with tuberculous lesions. Detailed meat inspection detected 65 (4.2%; 95% confidence interval (CI) = 3.3-5.4%) tuberculous lesions. From these, 20 (30.8%) samples were confirmed mycobacterium positive on culture, out of which 18 were Mycobacterium bovis and two were Mycobacterium tuberculosis. Routine meat inspection failed to detect tuberculous lesions in 23% of carcasses with TB lesions detected by detailed examination. However, no statistically significant difference was observed between both methods in detecting tuberculous lesions (Kappa = 0.87). Origin and age of the goats did not statistically affect the disease prevalence (P > 0.05). Histopathologic lesions were observed in 21 samples (68%; 95% CI = 50.1-81.4%) out of the 31 carcasses with gross tuberculous lesions examined by histopathology. Eighteen (58%) tuberculous samples positive for histopathology were also culture positive. The sensitivity and specificity of histopathology were 90% (95% CI = 76.9-100%) and 72.7% (95% CI = 46.4-99%), respectively, using culture as a reference test. To the best of our knowledge, this is the first report of caprine tuberculosis from Ethiopia. Further studies are required at the farm level to determine the prevalence of tuberculosis in the general goat population.

“…Severe outbreaks of caprine TB caused by M bovis have been reported in Ireland (Sharpe and others 2010), Portugal (Quintas and others 2010) and Italy (Domenis and others 2011). Other outbreaks of TB in goats in continental Europe have been caused by M caprae , but this member of the MTBC has not yet been reported in Great Britain.…”

Tuberculosis (TB) can be difficult to recognise owing to its diverse pathology and similar gross pathology to other conditions. Early detection of TB outbreaks goes a long way to preventing further spread of the disease. This article describes the spectrum of possible gross pathology of TB in a range of non-bovine farmed species for which there is no routine antemortem surveillance. For these species, detection of the disease is dependent on gross pathology at slaughter or postmortem examination findings.

Eighty-four Murciano-Granadina dairy goats slaughtered in the region of Murcia (South-East Spain) were necropsied to evaluate parasitic infections. The majority of the animals (94.0%) were parasitised and multiple infections were present. Twenty-one parasite species were found, including 18 nematode species (Muellerius capillaris, Dictyocaulus filaria, Neostrongylus linearis, Cystocaulus ocreatus, Teladorsagia circumcincta, T. occidentalis, T. trifurcata, Marshallagia marshalli, Camelostrongylus mentulatus, Trichostrongylus capricola, Nematodirus abnormalis, N. filicollis, N. spathiger, T. vitrinus, T. colubriformis, Trichuris spp., Chabertia ovina and Skrjabinema ovis); one trematode species (Dicrocoelium dendriticum); one arthropod species (Oestrus ovis); and one protozoa genus (Eimeria spp.). Additionally, 17.85% of the animals were Mycobacterium spp. positive. Therefore, comparison between parasite prevalence, intensity and abundance in tuberculosis-positive and -negative animals was performed. Statistically significant differences between the prevalence of lungworms and gastrointestinal nematodes in Mycobacterium spp. infected and free goats were found. The paper discusses this co-infection between Mycobacteriaceae and endoparasites.
