- Mycobacterium canetti
- Mycobacterium microti
- Longest replication time
MYCOBACTERIUM TUBERCULOSIS
Cord factor
VF of MYCOBACTERIUM TUBERCULOSIS
slow-growing; buff color; raised and dry; “CAULIFLOWER-LIKE APPEARANCE”. Rough colonies exhibit “cording” (Curve strands bacilli)
culture of MYCOBACTERIUM TUBERCULOSIS
(+) Niacin and Nitrate reduction
BT of MYCOBACTERIUM TUBERCULOSIS
20 to 22 hrs
replication time for m tuberculosis
- Tuberculosis in human and animals (cattle, dogs, cat and swine)
MYCOBACTERIUM BOVIS
- Attenuated strain used for vaccination (Bacillus- Calmette-Guerin or BCG vaccine)
MYCOBACTERIUM BOVIS
: Slow-growing, small, granular, rounded and non-pigmented
Culture of MYCOBACTERIUM BOVIS
(-) Niacin and Nitrate reduction
BT of MYCOBACTERIUM BOVIS
- Associated human cases of tuberculosis in tropical Africa
MYCOBACTERIUM AFRICANUM
- Detection of organism requires the use of spoligotyping (spacer oligotyping
MYCOBACTERIUM AFRICANUM
- Smooth strain of M. tuberculosis
MYCOBACTERIUM CANETTI
- Grows more rapidly than M. tuberculosis (6 days)
MYCOBACTERIUM CANETTI
- Isolated from an AIDS patient with mesenteric tuberculosis
MYCOBACTERIUM CANETTI
(+) Niacin and Nitrate reduction
BT of MYCOBACTERIUM CANETTI
Isolated from TB patients both immunocompromised and immunocompetent individuals
MYCOBACTERIUM MICROTI
M. avium, M. intracellulare, M. avium subsp. Paratuberculosis and M. avium subsp. silvaticum (wood pigeon bacillus)
MYCOBACTERIUM AVIUMCOMPLEX Specie
- Most common cause of Pulmonary infection to human, pathogen in AIDS.
MYCOBACTERIUM AVIUM COMPLEX
most common site of colonization and dissemination in AIDS.
GI tract
Pleomorphic, short coccobacilli without beading;
MYCOBACTERIUM AVIUM COMPLEX
(+) PAS
(+) Heat stable catalase
