PORTAGE LEARNING MICROBIOLOGY MODULE
5 QUIZ QUESTIONS AND ANSWERS 2022
◉ Mycobacterium TB transmission. Answer: Inhalation of
respiratory droplets
◉ TB pathology. Answer: bacteria survives and multiplies within
alveolar macrophages, immune cells produce tubercle around
infection; collagen fibers form around tubercle, cells in center die
and cause necrosis
◉ Secondary/reactivated TB/dissemination. Answer: occurs in 10%
of TB cases when bacteria released from ruptured tubercles causes
necrosis and/or migrates to other areas of the body
◉ Latent TB. Answer: when infected tubercles in lungs do not
rupture
◉ TB symptoms. Answer: cough/fever progressing to difficulty
breathing, fatigue, weight loss, chest pain, wheezing progressing to
coughing up blood and further weight loss
◉ Consumption. Answer: Old name for TB. refers to weight loss
caused by energy wasting due to coughing.
, ◉ TB diagnosis methods. Answer: - skin test with tuberculin
(easiest, shows prior development of immunity to TB)
- chest x-ray
- acid fast stain or fluorescence microscopy of sputum sample
- molecular test/interferon gamma release (measures immune
response)
◉ TB treatment. Answer: RIPE (rifampin, isoniazid, pyrazinamide,
ethambutol) for 8 weeks plus RI for another 18 weeks
◉ MDR-TB and XDR-TB. Answer: Multidrug resistant and extensively
drug resistant
Mycobacterium Tuberculosis, treated with fluoroquinolones or
aminoglycosides for up to 2 years
◉ TB prevention. Answer: BCG vaccine in areas of high transmission
◉ Mycobacterium leprae characteristics. Answer: - gram-positive
- bacillus
- acid-fast
- thrives at 30C temp
