A matched cohort study investigating the risk of Mycobacterium bovis infection in the progeny of infected cows

The aim of this study was to quantify the risk of bovine tuberculosis in the last progeny of cows confirmed with this infection using historical computerised records to perform a retrospective cohort study. The exposed cohort was defined as the last calf of dams that were diagnosed as having bovine tuberculosis during 2002. This document is a manuscript version of the paper.
