“…Livestock diseases pose a significant threat to human health, social wellbeing and economic activity (Michel et al 2010;Schiller et al 2011). Over 77 % of the pathogens affecting domestic mammals can infect multiple hosts (Cleaveland et al 2001;Martin et al 2011).…”

Interactions between four species in a complex wildlife: livestock disease community: implications for Mycobacterium bovis maintenance and transmission

Livestock diseases such as bovine tuberculosis can have considerable negative effects on human health and economic activity. Wildlife reservoirs often hinder disease eradication in sympatric livestock populations. Therefore, quantifying interactions between wildlife and livestock is an important aspect of understanding disease persistence. This study was conducted on an extensive cattle farm in southwest Spain, where cattle, domestic pigs, wild boar and red deer are considered to be part of a tuberculosis host community. We tested the hypothesis that the frequency of both types of interactions would be greater at food and water sites, due to the aggregation of individuals from multiple species at these locations. We measured direct and indirect interactions between individuals using GPS and proximity loggers. Over 57,000 direct interactions were recorded over a 2-year period, of which 875 (1.5 %) occurred between different species and 216 (0.38 %) occurred between wildlife and livestock. Most direct and indirect interactions occurred at water sites. Over 90 % of indirect interactions between wildlife and livestock took place within the estimated 3-day environmental survival time of Mycobacterium bovis in this habitat. Red deer home ranges and daily activity patterns revealed significant spatial and temporal overlaps with cattle, particularly in autumn. Suids and red deer also cross the farm boundary regularly, introducing a between-farm interaction risk. The infrequent occurrence of direct interactions between individuals from different species suggests that they are unlikely to be the sole mode of disease transmission and that indirect interactions may play an important role.

“…Mycobacterium bovis is the species most often isolated from tuberculous cattle. In addition to traditional skin test procedures, gamma interferon (IFN-␥) release assays (IGRAs) have been incorporated into TB testing algorithms for both humans and cattle (22,23). Such tests include the Quantiferon-TB Gold in-tube test (Cellestis Limited, Melbourne, Australia) and T-SPOT.TB (Oxford Immunotech, Oxfordshire, United Kingdom) for humans and Bovigam (Prionics Ag, Schlieren, Switzerland) for cattle.…”

“…It affects most domestic mammals and wild species, although not all species are equally susceptible to this infection (Neill et al 2005). In addition, the infection of cattle with this bacterium has been a concern for public and animal health authorities around the world for a long time (Schiller et al 2011). It corresponds to one of the most important diseases for dairy cattle farmers, responsible for generating clear negative effects on animal production systems.…”

ABSTRACT. The aim of the present study was to assess the performance of routinely used diagnostic tests to detect M. bovis infection in cattle populations with very low infection prevalence. A cross-sectional study was performed using 609 animals from 17 herds that were sampled for blood interferon, and tested with the caudal fold tuberculin test (CFT). It was planned that animals which showed CFT positive results were sent to the slaughterhouse for post mortem confirmation testing. However, not all the animals considered in the initial sampling were culled. Paired population proportions of positive results for the different diagnostic tools were compared. Apparent sensitivity and specificity was also estimated. Overall, intradermal tuberculin based diagnostics showed better performance in comparison to interferon based test, even though interferon was slightly more specific. From these results, it may be suggested that specific cut-off lines for interferon based techniques for certain areas with particular low bTB prevalence should be considered, as well as the modification of more specific antigens and the use of better combinations of PPDs if in vitro testing is intended must be taken into consideration. The uncertain role of interference bacteria that could be affecting the results of the in vitro analysis must be considered, and perhaps this could explain the apparent lack of consensus of the results obtained in Chile versus the ones obtained elsewhere. More studies must be performed in order to assess this issue.
