Figure 3From: Abattoir-based study on the epidemiology of caprine tuberculosis in Ethiopia using conventional and molecular toolsElectrophoretic separation of PCR products of RD9 deletion typing. Lanes: 1 = 100 bp DNA Ladder, 2 = M. tuberculosis (positive control), 3 = M. bovis (positive control), 4 = Qiagen H2O (negative control), Lanes 5–7 were isolates which generated a PCR product of 372 bp in Genus typing.Back to article page
