Which antibiotics can I use for Borrelia burgdorferi ?
(penicillin or tetracycline) in early stage, in late is often ineffective
Which bacteria posses waxy cell wall , which make them resistant to destruction and cause the organism to retain red dye when treated with acid
in acid-fast staining
Mycobacterium tuberculosis
✔️or✖️
Mycobacterium tuberculosis bacilli can infect any organ of the body, lungs most frequently involved.
✔️
caseating necrosis in the lower lobe of the lung, generally asymptomatic, but produce a positive Purified protein derivative (PPD) test.

Gram -ive bacteria called Mycobacterium tuberculosis
Chest X-ray with Ghon Focus diagnosis indicates for :
Tuberculosis (Gram -ive)
Specimen collection for M. tuberculosis
Culture on ……at 37C (4-8weeks)
Lowenstein Jensen medium
Molecular methods , Mantoux test are laboratory diagnosis of ……..
M. tuberculosis
✔️or✖️
Mantoux test – Positive test does not indicate active disease but exposure to M. tuberculosis .
✔️
Prophylaxis of M. tuberculosis
BCG vaccine (Bacillus of Calmette and Guerin)
intradermally
at the time of birth
Isoniazid (INH)
Pyrazinamide (PZA)

✔️or✖️
grows well in warmer regions of body including nose ,ears , eyebrows and testes
Is the characteristic of Mycobacterium leprae
✖️
Correction: Cooler regions
The laboratory diagnosis of which disease that collected Skin specimens and stained by Modified Acid fast staining (uses 0.5% H2SO4)
Mycobacterium leprae
✔️or✖️
Leprotic patients is not dangerous to others, they can live their life as usual
✖️
Leprotic patients are segregated in closed colonies to avoid the spread of infection
