SCITT, Single comparative intradermal tuberculin skin test; n.a., not available; RBT, Rose Bengal test; IFA, immunofluorescent assay; rPCR, real-time polymerase chain reaction; VNT, virus neutralization test.
In each cell prevalence is given in bold and higher size, immediately following by the number of positive individuals/number of individuals tested and the 95% confidence interval in parentheses.
Bovine tuberculosis SCITT results aggregated across the study period. Foot-and-mouth and Rift Valley fever and lumpy skin disease results are given for the October 2008 sampling. Brucellosis and theileriosis results are given for samples collected between August 2007 and October 2009. Positivity is decided upon consideration of positivity for both Rose Bengal and c-ELISA tests.
