Table 1.
Logistic regression analysis of tuberculous lesions with various host-related risk factors.
Figure 1.
Tuberculous lesions from camels on different organs.
(A1) Disseminated and distinct tuberculous lesions in mediastinal parts of the lung. (A2) Tuberculous lesion in mediastinal lymph node and nodules on other parts as indicated by arrows. (A3) Tuberculous lesions in hepatic lymph node. The arrows show that pea-sized lesions throughout the lymph node. (B) Tuberculous lesion in mesenteric lymph nodes as indicated by arrow.

Figure 3.
Gel electrophoresis separation of PCR products by multiplex PCR genus typing of mycobacteria isolated from naturally infected camels.
Lane 1 = 100bp DNA Ladder; Lane 2 = Mycobacterium avium complex (positive control), Lane 3 = Qiagen H2O (negative control), Lane 4 = Mycobacterium tuberculosis complex (positive control), Lanes 5–34 were isolates from individual camels with tuberculous lesions. Lane 7 (sample 63), Lane 8 (sample 62) were positive for Mycobacterium tuberculosis complex and Lane 5, 6, 7, 8, 9, 11, 12–13, 15–22, 25, 28, 29, 34 were positive for genus Mycobacterium, Lane 10, 14, 23, 24, 26, 27, 30–33 were negative for genus Mycobacterium.
Figure 4.
Gel electrophoresis separation of PCR products by RD4 deletion typing of mycobacteria isolated from naturally infected camels.
Lane 1 = 100bp DNA ladder, Lane 2 = M. tuberculosis positive control, Lane 3 = Qiagen H2O (negative control), Lane 4 = M. bovis positive control, Lane 5–7 were isolates from camel, Lane 6 and 7 were positive for M. bovis.
Figure 5.
Schematic representation of the spoligotyping patterns of isolates of Mycobacterium bovis from camels with tuberculous lesions.
A = M.bovis SB1176 (positive control); B = Qiagen H2O (negative control); C = M. tuberculosis (positive control); D = sample 63 (SB1953-New strain); E = sample 62 (SB0133). The black rectangles represent positive signals, and the white rectangles indicate negative signals.
