Microbiological study of mycetoma patients from Bombay with special reference to actinomyces immunofluorescence.

ABSTRACT

17 of the 21 clinically diagnosed mycetoma and actinomycosis cases studied yielded positive cultures. Foot, leg, inguinal region, chest wall, jaw and scalp were the affected sites. 15 of the patients were from Bombay, 13 of them had infection due to Nocardia species and 2 had Actinomyces israelii infection. The other two patients from South India had Madurella mycetomi infection. N.brasiliensis was commonest isolate (8). Other isolates were N.asteroides (2), N.pelletieri (2), N.caviae (1) and A.israelii (2). A direct fluorescent antibody test to detect actinomyces was used in selected cases (4). Two of whom gave positive immunofluorescence with A.israelii FITC labeled globulin, in primary smears as well as in cultures.
