Epidemiological investigation of bovine tuberculosis herd breakdowns in Spain 2009/2011.

We analyzed the most likely cause of 687 bovine tuberculosis (bTB) breakdowns detected in Spain between 2009 and 2011 (i.e., 22% of the total number of breakdowns detected during this period).

Spatio-temporal variability of bovine tuberculosis eradication in Spain (2006-2011).

In this study we analyzed the space-time variation of the risk of bovine tuberculosis (bTB) in cattle between 2006 and 2011. The results indicated that at country level, there were no significant temporal changes between years, but, at county level bTB evolution was more heterogeneous. In some counties, between some years, the prevalence and the incidence of the disease was higher as compared to the global rate in the rest of the counties of Spain.

Risk factors for bovine tuberculosis persistence in beef herds of Southern and Central Spain.

In order to assess risk factors related to bovine tuberculosis (bTB) persistence, a case-control study, comparing persistent versus transient bTB infected beef farms from Central and Southern Spain, was conducted. Farms were matched by herd size and geographical location (county). A questionnaire administered by personal interview was conducted on 150 herds (80 controls and 70 cases) from Andalucia and Castilla La Mancha regions.
