Growth, Congo Red agar colony morphotypes and antibiotic susceptibility testing of Mycobacterium avium subspecies paratuberculosis.
OBJECTIVE Mycobacterium avium subspecies (subsp.) paratuberculosis (MAP) is the causative agent of Johne's disease in ruminants and has been associated with Crohn's disease in humans. We sought to test growth rates and susceptibilities of various strains of MAP in two available growth media. DESIGN Paired comparison design. METHODS Using the BACTEC macrobroth radiometric growth system and C...
متن کاملRadiology of pulmonary Mycobacterium avium-intracellulare complex.
Although the radiographic appearance of pulmonary MAC infection in the immunocompetent host can be varied, there are several generalizations that can be made. The classic radiographic appearance is indistinguishable from that of pulmonary tuberculosis. The classic form is seen most commonly in males and is typically associated with other predisposing diseases, especially chronic obstructive pul...
متن کاملMycobacterium Avium-intracellulare Sinusitis.
M ycobacterium avium-intracellulare (MAI) sinusitis is rarely diagnosed. There are only nine previous cases documented in the literature, most of which are in patients with acquired immune deficiency syndrome (AIDS). Awareness of MAI sinusitis may prove valuable to the practicing otolaryngologist, and an elevated index of suspicion is necessary in all immunocompromised patients with sinusitis, ...
متن کاملEffect of growth in biofilms on chlorine susceptibility of Mycobacterium avium and Mycobacterium intracellulare.
Mycobacterium avium and Mycobacterium intracellulare were grown in suspension and in biofilms, and their susceptibilities to chlorine were measured. M. avium and M. intracellulare readily adhered within 2 h, and numbers increased 10-fold in 30 days at room temperature in biofilms on both polystyrene flasks and glass beads. The chlorine resistance of M. avium and M. intracellulare cells grown an...
متن کاملFactors influencing the chlorine susceptibility of Mycobacterium avium, Mycobacterium intracellulare, and Mycobacterium scrofulaceum.
The susceptibility of representative strains of Mycobacterium avium, Mycobacterium intracellulare, and Mycobacterium scrofulaceum (the MAIS group) to chlorine was studied to identify factors related to culture conditions and growth phase that influenced susceptibility. M. avium and M. intracellulare strains were more resistant to chlorine than were strains of M. scrofulaceum. Transparent and un...
