“…Several PCR assays, including multiplex conventional and real-time PCR, have been developed for detection of mastitic pathogens including Staphylococcus spp., E. coli, M. bovis, S. agalactiae and Enterococcus spp. (Koskinen et al, 2009;Taponen et al, 2009;Shome et al, 2011;Hiitiö et al, 2015;Barbier et al, 2016). A comprehensive background of the molecular epidemiology of mastitis pathogens, particularly at subspecies level, with relevance to public health is reported by Zadoks et al (2011).…”

Bovine mastitis is an important animal production disease that affects the dairy industry globally. Studies have estimated the prevalence of this disease in approximately 30% of African countries, with the highest prevalence found in Ethiopia. This is despite the wide cattle distribution in Africa, and the largest number of dairy farms and herds in countries such as South Africa, Kenya and Uganda. Furthermore, the estimated financial losses due to direct and indirect impacts of bovine mastitis are lacking in this continent. Therefore, intensive research efforts will help determine the continent-wide economic impacts and advance careful monitoring of disease prevalence and epidemiology. Here, published cases supporting the occurrence and importance of bovine mastitis in certain regions of Africa are outlined.

“…Environmental contamination with M. bovis remains poorly understood. The presence of M. bovis DNA, not necessarily viable, in environmental matrices, such as soil, sediments, water, grass, corn and hay, has been reported in several studies (Adams, Bolin, Fine, Bolin, & Kaneene, 2013; Barasona et al, 2017; Barbier, Boschiroli, et al, 2016; Barbier, Rochelet, Gal, Boschiroli, & Hartmann, 2017; Fine, O'Brien, Winterstein, & Kaneene, 2011; Santos, Santos, et al, 2015). Substrate contamination is believed to be the result of urine, faeces, saliva and/or nasal excretion by infected animals.…”

“…The temperature of air and soil, but also the evapotranspiration rate, is among the most consistent positively associated variables with the probability of detecting MTC DNA in environmental samples. M. bovis has been found in higher concentration in moderate temperature and high water content, opposite to the characteristic high temperature and low water content of the dry season in summer (Adams et al, 2013; Barbier, Boschiroli, et al, 2016; Barbier et al, 2017; Santos, Almeida, Gortázar, & Correia‐Neves, 2015; Santos, Santos, et al, 2015; Young, Gormley, & Wellington, 2005). Besides, shade has been correlated with persistence of environmental M. bovis due to the maintenance of high water content and moderate temperature, but also due to low sunlight association with low ultraviolet radiation, leading to less cell stress and mutations, improving bacterial survival (Rodríguez‐Hernández et al, 2016).…”

Animal tuberculosis (TB) in terrestrial mammals is mainly caused by Mycobacterium bovis. This pathogen is adapted to a wide range of host species, representing a threat to livestock, wildlife and human health. Disease heterogeneity is a hallmark of multi‐host TB and a challenge for control. Drivers of animal TB heterogeneity are very diverse and may act at the level of the causative agent, the host species, the interface between mycobacteria and the host, community of hosts, the environment and even policy behind control programmes. In this paper, we examine the drivers that seem to contribute to this phenomenon. We begin by reviewing evidence accumulated to date supporting the consensus that a complex range of genetic, biological and socio‐environmental factors contribute to the establishment and maintenance of animal TB, setting the grounds for heterogeneity. We then highlight the complex interplay between individual, species‐specific and community protective factors with risk/maintenance variables that include animal movements and densities, co‐infection and super‐shedders. We finally consider how current interventions should seek to consider and explore heterogeneity in order to tackle potential limitations for diagnosis and control programmes, simultaneously increasing their efficacy.

“…In such circumstances, biosecurity measures preventing badger ingress to farm buildings are unlikely to have an effect in reducing bTB risk in cograzing cattle (Mullen et al., ; O'Mahony, ; Mullen et al., ; O'Mahony, ,b). There is also evidence of cattle exposure to environmental contamination from wildlife sources (King et al., ; Barbier et al., ).…”

Bovine tuberculosis has been assessed according to the criteria of the Animal Health Law (AHL), in particular criteria of Article 7 on disease profile and impacts, Article 5 on the eligibility of bovine tuberculosis to be listed, Article 9 for the categorisation of bovine tuberculosis according to disease prevention and control rules as in Annex IV and Article 8 on the list of animal species related to bovine tuberculosis. The assessment has been performed following a methodology composed of information collection and compilation, expert judgement on each criterion at individual and, if no consensus was reached before, also at collective level. The output is composed of the categorical answer, and for the questions where no consensus was reached, the different supporting views are reported. Details on the methodology used for this assessment are explained in a separate opinion. According to the assessment performed, bovine tuberculosis can be considered eligible to be listed for Union intervention as laid down in Article 5(3) of the AHL. The disease would comply with the criteria as in Sections 2, 3, 4 and 5 of Annex IV of the AHL, for the application of the disease prevention and control rules referred to in points (b), (c), (d) and (e) of Article 9(1). The main animal species to be listed for bovine tuberculosis according to Article 8(3) criteria are several mammal species, as indicated in the present opinion.

First molecular detection of Mycobacterium bovis in environmental samples from a French region with endemic bovine tuberculosis

Abstract: All together, these results suggest that Myco. bovis occurs at low levels in environmental matrices in Côte d'Or within the bTB-infected area. Drinking contaminated water or inhaling contaminated bioaerosols might explain cattle infection in some cases.
