Seven hundred and fifty-one feral pigs from the subcoastal plains of the Northern Territory were examined. The sample population consisted of 52.4% females and 47.6% males. They ranged in age from newborn piglets to mature animals of over 72 months. Of the pigs examined 47.7% had macroscopic abscesses and of these 80.2% were probably caused by mycobacteria. Tissues from 193 pigs were examined bacteriologically and 93 strains of mycobacteria were isolated. These were typed as M. bovis (37 strains); M. avium serotype 2 (1); M. intracellulare serotypes 6 (2), 7 (3), 9 (1) and 18 (1); M. intracellulare double serotypes 6 + 12 (1), 8 + 12 (1), and 11 + 12 (1); M. intracellulare unclassified serotype (4); M. scrofulaceum serotype 41 (1); M. scrofulaceum unclassified serotype (7); M. gordonae (2); M. Kansasii (1); M. simiae (2); M. szulgai (2); M. vaccae (1); and M. xenopi (2). Additionally, 3 strains were unidentifiable members of the M. avium-M. intracellulare-M. scrofulaceum (MAIS) complex, one strain was a Runyon's group IV and 4 strains were typed as members of the genus Rhodococcus. Five strains were non-viable on subculture and 10 did not conform to any currently recognised species of mycobacteria. Of the 93 strains, 3 were isolated from tissue that did not contain macroscopic lesions, viz. M. simiae, Runyon's group IV and an unidentifiable member of the MAIS complex. It was concluded that the feral pig is probably an end host for both M. bovis and atypical mycobacteria and not a significant source of infection for cattle. M. bovis is not a significant cause of mortality in feral pigs but mycobacterioses are a significant cause of morbidity. With increasing age, the proportion of pigs having lesions increased whereas the proportion of lesions from which mycobacteria could be isolated decreased.
对来自北领地近岸平原的751头野猪进行了检查。样本群体中雌性占52.4%，雄性占47.6%。其年龄范围从新生仔猪到72个月以上的成年动物。在检查的猪中，47.7%有肉眼可见的脓肿，其中80.2%可能由分枝杆菌引起。对193头猪的组织进行了细菌学检查，分离出93株分枝杆菌。这些菌株被分型为牛分枝杆菌（37株）；鸟分枝杆菌血清型2（1株）；胞内分枝杆菌血清型6（2株）、7（3株）、9（1株）和18（1株）；胞内分枝杆菌双血清型6 + 12（1株）、8 + 12（1株）和11 + 12（1株）；胞内分枝杆菌未分类血清型（4株）；瘰疬分枝杆菌血清型41（1株）；瘰疬分枝杆菌未分类血清型（7株）；戈登分枝杆菌（2株）；堪萨斯分枝杆菌（1株）；猿分枝杆菌（2株）；苏尔加分枝杆菌（2株）；母牛分枝杆菌（1株）；和偶发分枝杆菌（2株）。此外，3株是鸟分枝杆菌-胞内分枝杆菌-瘰疬分枝杆菌（MAIS）复合体中无法鉴定的成员，1株是Runyon IV组，4株被分型为红球菌属的成员。5株在传代培养时无活力，10株不符合目前任何公认的分枝杆菌菌种。在这93株菌株中，3株是从不含肉眼可见病变的组织中分离出来的，即猿分枝杆菌、Runyon IV组和MAIS复合体中无法鉴定的成员。得出的结论是，野猪可能是牛分枝杆菌和非典型分枝杆菌的终宿主，而不是牛感染的重要来源。牛分枝杆菌不是野猪死亡的重要原因，但分枝杆菌病是发病的重要原因。随着年龄的增长，有病变的猪的比例增加，而能分离出分枝杆菌的病变比例下降。
