“…Exeperiment 1 has shown that the M . intracellidare serotype VI isolated from the outbreak of tubercular lymphadenitis (Tammemagi and Simmons 1968) would cause lesions of a similar type in experimentally infected pigs. During the first 7 months of an outbreak when 67% of 1768 pigs had gross lesions at slaughter, M .…”

Summary The pathologic response of pigs to a strain of M. intracellulare serotype VI was investigated in three trials. Ten mg wet weight of the second subculture maintained on Löwenstein‐Jensen slopes produced a large number of tubercular nodules in the mesenteric lymph node of one pig infected orally, and similar lesions in the iliac lymph nodes of another pig following injection of the culture into the gluteal muscles. The lesions so produced were comparable with those recorded in the outbreak of tubercular lymphadenitis from which the above strain was isolated. In two other trials, variable doses ranging from 1.3 to 63 mg wet weight Löwenstein‐Jensen, harvested from the fourth and fifths subculture of this strain, were administered to 13 pigs. The number and size of lesions produced were much smaller, and in several instances no gross or microscopic lesions were detected. Further work is being done to investigate the factors resulting in decreased virulence of this strain of M. intracellulare for pigs.

“…Disc u SF i on Tammemagi and Simmons ( 1968 ) reported that tuberculous lesions were produced in two pigs by intramuscular and oral administration of a strain (serotype VI) of M. intracellulure (= Battey) isolate obtained from the first outbreak of Battey mycobacteriosis reported from Queensland. The dose used in both pigs was 10 mg wet culture (unpublished data).…”

“…Battey-type mycobacteriosis of pigs was described in Queensland by Tammemagi and Simmons (1968), who reported the isolation of Mycobacterium intracellulare (serotype VI, Runyon Group 3, Battey mycobacteria) from diseased lymph nodes obtained from a piggery in south-eastern Queensland. Since then M .…”

“…Two species of Chlamydia have principally been reported to infect sheep, C. 57 abortus which is a major cause of abortion in both sheep and goats, and C. pecorum, which 58 causes pneumonia, arthritis/polyarthritis, encephalomyelitis, conjunctivitis, enteritis, abortion 59 and metritis and infertility in domestic ruminants and pigs (Everett, techniques that would not have detected C. pecorum. Despite this, arthritis/polyarthritis due 78 to C. pecorum is known to occur in Australia, and has been reported from 13-month old rams 79 in Queensland (Tammemagi and Simmons, 1968) and from 3-6 month old lambs on the 80…”
