SEROVARS OF MYCOBACTERIUM-AVIUM COMPLEX ISOLATED FROM PATIENTS IN DENMARK

Danish isolates of Mycobacterium avium complex were serotyped by the u se of seroagglutination. The most prevalent serovars among patients wi th AIDS (n = 89) were 4 and 6, while among non-AIDS patients the most prevalent serovars were 1, 6, and 4, with no major differences between those in patients with pulmonary disease (n = 65) and those in patien ts with lymph node infection (n = 58). The results suggest a Scandinav ian distribution of serovars with a predominance of serovar 6 and fail to demonstrate any selective protection against different serovars by Mycobacterium bovis ECG vaccination.
