“…The dominance of M. auium complex strains is in agreement with results from USA (Acland & Whitlock 1986). We have previously shown a significantly more sensitive and rapid primary isolation of M. auium complex with the Bactec system compared with conventional culture on solid medium, in the examination of clinical materials from human patients with mycobacterial disease (Hoffner 1988).…”

“…Recently some improvements have been made to the Bactec system. The new 7H12B culturing vial allows an increased inoculum of sample material, which makes the system more sensitive for primary isolation of mycobacteria (Libonati et al. 1986;Stager & Davis 1986).…”

“…Tuberculosis in wild boar is caused by Mycobacterium tuberculosis complex (including M. tuberculosis and M. bovis ) and M. avium complex ( Corner et al, 1981; Biolatti et al, 1992; Kalensky, 1992; Schultz et al, 1992), but, without culturing, differentiation between them is made difficult by overlapping patterns in both their macroscopic and their histological appearances ( Ray et al, 1972; Acland and Whitlock, 1986).…”

A detailed macroscopic and histological description is given of tuberculous-like lesions in mandibular lymph nodes obtained from wild boar (Sus scrofa) collected in Italy during the 1995/1996 hunting season, as well as a correlation with results obtained from a Mycobacterium tuberculosis complex target amplified test system. According to macroscopic appearance, lesions were largely represented by caseous-necrotic-calcified granulomata (n = 272/285; 95.4%), while histological investigations showed mainly necrotic-calcified (n = 82/218; 37.6%) and fibronecrotic-calcified (n = 81/218; 37.2%) lesions. When tested with a target rRNA amplification/hybridization technique to detect M. tuberculosis complex, 112 (43.6%) samples out of 275 tested gave positive results.

“…The importance of this infection has increased in recent years due to the raising number of observed lesions in slaughtered animals, generating economic loss by carcasses condemnations (1,8,14). The infection is also a potential hazard to public health (19) although all possible inter-relations between agent, host and environment are not yet known.…”

Swine mycobacteriosis is an important cause of carcass condemnation at abattoirs. One of the best ways to recognize the etiologic agent involved, in live animals, is the fecal isolation, as 94% of the lesions are located in the digestive tract. Therefore, the goal of the present study was to compare the performance of four decontamination methods followed by inoculation in three different culture media, totalizing twelve procedures of mycobacteria search from swine fecal samples experimentally contaminated. The swine feces were artificially contaminated with 0.02 g of Mycobacterium avium, PIG-B strain, and subjected to mycobacteria isolation trial. The protocols used were: 1) modified Petroff or basic method; 2) modified Lowenstein-Jensen or acidic method; 3) modified Petroff or basic method with re-suspension in Amphotericin B; 4) modified LowensteinJensen or acid method with re-suspension in Amphotericin B, followed by inoculation in Petragnani, Lowenstein-Jensen and Lowenstein-Jensen medium with antibiotics (Penicillin G and Nalidixic acid). There was a difference (p<0.05) between the mycobacterial recovery percentages from swine feces. The acid method with re-suspension in Amphotericin B solution and inoculation in Lowenstein-Jensen medium with antibiotics showed the best results (87% of mycobacteria recovery).
