^a: Number of positives samples/total number of rats

^b: The confidence intervals of the concentrations of genomic copies/μL of the positive samples with 0.95 probability are in brackets

*with 0.75 probability.

The other samples (blood, feces, saliva, liver, spleen, lung, salivary gland and bronchoalveolar lavage) tested negative for the Lfb1 gene by qPCR [28].
