Hypersensitivity pneumonitis caused by Mycobacterium avium subsp. hominissuis in a hot tub, as proven by IS1245 RFLP and rep-PCR typing.
نویسندگان
چکیده
A symptomatic patient had repeatedly positive cultures of Mycobacterium avium subsp. hominissuis after exposure to a hot tub contaminated with M. avium subsp. hominissuis. The pulmonary and tub water isolates were indistinguishable by IS1245 RFLP as well as rep-PCR typing. Discontinued use of the hot tub resulted in culture conversion.

BACKGROUND Animal mycobacterioses are regarded as a potential zoonotic risk and cause economical losses world wide. M. avium subsp. hominissuis is a slow-growing subspecies found in mycobacterial infected humans and pigs and therefore rapid and discriminatory typing methods are needed for epidemiological studies. The genetic similarity of M. avium subsp. hominissuis from human and porcine origi...

A PCR method previously developed for typing Mycobacterium avium was used to characterize the genetic diversity of M. avium strains isolated from swine (n = 90) and humans (n = 24). The strains were identified with IS901 PCR and IS1245 PCR: 38 strains were of IS901+ and IS1245+ genotype (M. avium subsp. avium) and 76 strains were of IS901– and IS1245+ genotype (M. avium subsp. hominissuis). All...

In early 1999, there was an increased incidence of tuberculous lesions in the lymph nodes of slaughtered pigs in the Czech Republic. In part 1 of this study, tuberculous lesions were detected in 140 (62%) tissue samples collected from pigs coming from 15 farms in 15 districts at routine veterinary meat inspections in abattoirs. Mycobacteria were isolated from 37 (16%) tissue samples: 34 Mycobac...
متن کاملInvestigation of an outbreak of mycobacteriosis in pigs
BACKGROUND A high proportion of pigs imported to Serbia from a Lithuanian breeding herd reacted positively against avian and/or bovine tuberculin. The pigs were euthanized and lesions characteristic for mycobacterial infection were detected. An investigation of potential mycobacteriosis in the pigs imported to Serbia and the possible source of infection in the Lithuanian herd were therefore ini...
متن کاملMolecular evidence to support a proposal to reserve the designation Mycobacterium avium subsp. avium for bird-type isolates and 'M. avium subsp. hominissuis' for the human/porcine type of M. avium.
In an attempt to clarify the taxonomy of the Mycobacterium avium complex, the relationship between IS1245 RFLP, growth temperature, 16S rDNA signature sequences and the 16S-23S rDNA internally transcribed spacer (ITS) of 160 M. avium-complex isolates from different sources was investigated. All 70 isolates identified as M. avium by INNO-LiPA MYCOBACTERIA (Innogenetics, Belgium), a DNA probe tes...
