(25 cards)
cause by Ingestion of milk from infected cows
M. bovis
Primarily identified as the cause of approximately half of the cases of TB in West Africa
M. africanum
Identified by its susceptibility to pyrazinamide; Reservoir hosts: goats, cattle, sheep, pigs, wild boars, deer and fox
M. caprae
Typically found in rodents, guinea pigs, rabbits, cats, llamas, and meerkats
M. microti
Primarily identified in cases of lymphadenitis and generalized tuberculosis in immunocompromised individuals
M. canetti
Transmitted form sealions to humans; Associated with granulomatous lesions in the lymph nodes, lungs, pleura, and
spleen
M. pinnipedii
Reservoir host: banded mongoose
M. mungi
Reservoir host: large mammals (gazelle, antelopes, and oryxes)
M. orygis
Slow-growing NTM; Produce colonies that require light to form
Runyon I: Photochromogens
Slow-growing NTM; Produce pigmented colonies whether grown in the dark or light
Runyon II: Scotochromogens
Slow-growing NTM; Produce unpigmented colonies whether grown in the dark or the light
Nonphotochromogens
Most commonly isolated NTM in the United States; Noteworthy for its pathogenic role in pulmonary infections in patients with AIDS and HIV
Mycobacterium avium Complex
causative agent of leprosy; Can be cultivated in the armadillo and footpads of mice
MYCOBACTERIUM LEPRAE
most common sexually transmitted bacterial pathogen and a major
cause of pelvic inflammatory disease (PID), ectopic pregnancy, and infertility;

Rickettsia prowazekii
Rickettsia typhi vector
fleas
scrub typhus; chiggers
Orientia tsutsugamushi
causative agent of Q fever
Coxiella
Identified as the causative agent of Whipple disease
Trophryma whipplei
Etiologic agent of granuloma inguinale or donovanosis
Encapsulated, pleomorphic, gram-negative bacillus
Usually observed in vacuoles in the cells of large mononuclear cells
Klebsiella granulomatis
Smallest known free-living forms
• Prokaryotes
• Do not have a cell wall
• Ubiquitous in the plant and animal kingdoms
Mycoplasmas
Walking pneumonia; spherical, grainy, yellowish forms that are embedded in the agar, with a thin outer layer
M. pneumoniae:
