[Cultural, biochemical and serological characteristics of Mycobacteria, avium and atypical, isolated from pigs slaughtered in the Białystok abattoirs].
Two hundred and thirty-eight strains of acid-fast bacilli isolated from lymph nodes of pigs were examined. Among these strains 198 were classified as Myc. avium and 40 - as atypical bacilli belonging to group II, III and IV of Runyon's classification. Only 118 strains of Myc. avium showed cultural and biochemical properties typical for these species. Some of the remaining strains were positive in the arylsulphatase test, in the reduction nitrate test or in the hydrolysis of Tween 80 test, but were negative in all amidase tests. The serological study of the bacilli belonging to Myc. avium - intracellulare group was performed according to Schaefer's method. It was found that among Myc. avium strains serotype 2 dominated (187 strains). Myc. avium serotypes 1 and 3 appeared sporadically. The majority of atypical bacilli were classified as Myc. fortuitum, and only some strains were identified as Myc. intracellulare and Myc. vaccae. Some strains remained unclassified. The results showed that identification of Myc. avium and some atypical strains isolated from pigs by means of cultural and biochemical tests is not sufficient. The agglutination test with the use of sera specific for individual serotypes of Myc. avium - intracellulare group is very useful for identification of bacilli belonging to these groups. If we have a full set of specific sera we can identify Myc. avium and Myc. intracellulare more quickly and better than with use of cultural and biochemical tests.
