Host Richness Increases Tuberculosis Disease Risk in Game-Managed Areas

Investigation published in Microorganisms

Current scientific debate addresses whether species richness in animal communities may negatively moderate pathogen transmission and disease outcome (dilution effect), or to the contrary, if disease emergence benefits from more diverse community assemblages (amplification effect). The result may not depend exclusively on patterns of host species biodiversity but may depend on the specific composition of reservoir hosts and vectors, and their ecology. Host–pathogen interactions have shaped variations in parasite virulence, transmissibility and specificity. In the same way the importance of fact… Read more

Weaned piglets: another factor to be considered for the control of Salmonella infection in breeding pig farms

Investigation article published in Veterinary Research

Field studies on Salmonella infection in suckling piglets are scarce due to the intrinsic difficulties of collecting proper samples (i.e. tonsils or mesenteric lymph nodes), and most of them rely on the analysis of rectal swabs that limit their accuracy. We used 495 slaughtered 4-weeks-old male piglets intended for human consumption from 5 Salmonella-seropositive breeding farms to collect gastrointestinal packages and perform a thorough detection of Salmonella on mesenteric lymph nodes and intestinal content. The overall prevalence of both infection and shedding was high (≈ 36%) in… Read more

High Load of Deformed Wing Virus and Varroa destructor Infestation Are Related to Weakness of Honey Bee Colonies in Southern Spain

Frontiers in Microbiology publish this investigation article

Many factors, including pathogens, contribute to the continuing losses of colonies of the honey bee Apis mellifera, which has led to steady population decline. In particular, colony losses have been linked to deformed wing virus (DWV) and the Varroa destructor mite. To clarify the potential role of these two pathogens in honey bee colony weakening and loss, we sampled colonies in southern Spain during a 21-month period and analyzed the samples for loads of four viruses and varroa. Loads of DWV and black queen cell virus as well as varroa infestation negatively correlated with colony vigor as m… Read more

Moving beyond descriptive epidemiology

Interview in CAHFS News of University of Minnesota

“Often we are not able to identify all the factors related to the space, but we can certainly look into the distribution of these health events,” says Julio Alvarez, DVM, PhD, who was among the course instructors who illustrated the full extent of U of M resources that can be utilized in future collaborations with MDH. “We can study the spatial patterns and then test whether or not those patterns are statistically significant.” Alvarez is an adjunct professor at CVM who primarily works at the Veterinary Health Surveillance Center at the Complutense University of Madrid, where his research take… Read more

Diagnostic interaction between bovine tuberculosis (bTB) and Johne`sdisease in bTB highly prevalent dairy farms of Uruguay

Veterinary and Animal Science publish this investigation article

The consolidation of the dairy industry, with increase in sizes, density and productivity of the herds, was associated to unprecedented bovine tuberculosis (bTB) prevalence levels in dairy herds in Uruguay, where Johne`s disease (JD), another mycobacterial disease, is also prevalent. Here, we aimed to characterize the association between bTB- and JD-diagnostic results in two heavily bTB- and JD-coinfected dairy herds. Results from bTB-intradermal tests and JD-ELISA in 686 cows indicated a significantly (P < 0.001) higher frequency of bTB-positive animals in the JD-positive population, in which… Read more
