Слайд 2


Слайд 3Mycobacterium tuberculosis
Mycobacterium leprae (uncommon)
Mycobacterium avium-intracellulaire Complex (MAC) or (M. avium)
Important Human

Pathogens

Слайд 4Lipid-Rich Cell Wall of Mycobacterium
CMN Group: Unusual cell wall lipids (mycolic

acids,etc.)

(Purified Protein Derivative)


Слайд 5Acid-Fast (Kinyoun) Stain of Mycobacterium
NOTE: cord growth (serpentine arrangement) of virulent

strains

Слайд 6Photochromogenic Mycobacterium kansasii on Middlebrook Agar
NOTE: Mycobacteria pathogenic for humans can

be differentiated (Runyon Groups) by:
speed of growth (all are slower than most other pathogens) and by
production of chromogenic pigments (in light, in dark, or none)

Слайд 7Improved Mycobacterial Isolation Medium


Слайд 8Eight Week Growth of Mycobacterium tuberculosis on Lowenstein-Jensen Agar


Слайд 9Pathogenic Mycobacterium spp.
BCG
AIDS patients


Слайд 10Mycobacterial Clinical Syndromes


Слайд 11Diagram of a Granuloma


NOTE: ultimately a fibrin layer develops

around granuloma (fibrosis), further “walling off” the lesion.
Typical progression in pulmonary TB involves caseation, calcification and cavity formation.

Слайд 12Laboratory Diagnosis of Mycobacterial Disease


Слайд 13Differential Characteristics of Commonly Isolated Mycobacterium spp.


Слайд 15Mycobacterium tuberculosis


Слайд 16Mycobacterium tuberculosis Infections


Слайд 17Incidence of Tuberculosis in USA


Слайд 18Mycobacterium tuberculosis Infections (cont.)
BCG (bacille Calmette-Guerin) = attenuated M. bovis
Positive PPD

+ Chest X-Ray +

MDR-TB a serious global health threat


Слайд 19Pneumonia
Granuloma formation with fibrosis
Caseous necrosis
Tissue becomes dry & amorphous (resembling cheese)
Mixture

of protein & fat (assimilated very slowly)
Calcification
Ca++ salts deposited
Cavity formation
Center liquefies & empties into bronchi

Typical Progression of Pulmonary Tuberculosis
