(1) Rifampin(2) Isoniazid(3) Pyriazinamide(4) Ethambutol Other than the lung, where can TB produce cavitary lesions? What is called when TB infects the vertebrae? Name the triad of symptoms of reactivation TB What part of the lung does secondary TB affect?
TNF-α also leads to cachexia, explaining associated weight loss) TNF-α (∴ TNF-α inhibitors ⇒ Reactivation. What cytokine is required to prevent reactivation of TB? Chapter 1: Gram Positive Cocci B 1. Miliary TB(⇒ Seeding of many different organs) View from MICRO 101 at Jordan University of Science and Technology. What do you call it when primary TB results in bacteremia? Why might someone who has never been exposed to TB have a positive PPD?īCG vaccine(Common in those from countries where TB is endemic) Lesions heal/fibrose ⇒ Latent(People usually contract primary TB in childhood) What is the most common outcome of primary TB? Inhibits fusion of phagolysosome ⇒ Allows intracellular survivalĪfter PRIMARY tuberculosis, the following are present:(1) Fibrotic/calcified lung lesions(2) Big hilar lymph nodes(⇒ Fibrosis and calcification = Ranke complex) Stimulates MΦs to make granulomas(It activates MΦs, promoting granuloma formation by stimulating TNF-α release) What culture medium can be used to grow M. What component of the mycobacterial cell wall takes up the Carbol-Fuschin stain? (1) Acid fast(2) Obligate aerobe(Facultative intracellular vs. #SketchyMicro #SketchyMicro::Bacteria::(08)-Mycobacteria::8.2-Mycobacterium_leprae $$Bacteria $MycobacteriaĬharacterize (2) : Mycobacterium tuberculosis These infections are acquired by the mother and passed either transplacentally or during the birth process. In US, the animal reservoir for Mycobacterium leprae are armadillos. TORCH infections are a group of congenitally acquired infections that cause significant morbidity and mortality in neonates. Mycobacterium leprae is a non tuberculous mycobacteria and it causes a disease called leprosy, or Hansen disease. (1) Dapsone(2) Rifampin(3) Clofazimine(For up to 5 years) Mycobacterium leprae is a rod-shaped bacteria which was first discovered in 1873 by Hansen.
#SKETCHY MICRO LISTERIA SKIN#
(1) Symmetric glove and stocking neuropathy(2) Skin lesions on extensor surfaces(3) "Leonine facies" Name 3 signs/symptoms of lepromatous leprosy Lepromatous(Notice that they're holding hands, representing transmission) Which form of leprosy has human to human transmission? Inject leprosy antigen ⇒ Type IV hypersensitivity Well demarcated hair loss(Anywhere, not just head) What is the main symptom of tuberculoid leprosy? Th2(⇒ Humoral response ∴ Poorly forms granulomas) Which immune response predominates in the lepromatous form of leprosy? Which immune response predominates in the tuberculoid form of leprosy? Why does Leprosy predominantly affect the extensor surfaces? However, people with severe illness and those with underlying conditions that weaken the immune system should be given. Most people recover without needing antibiotics. Symptoms usually begin 12 days after infection and last 7 days. Most people with Shigella infection have diarrhea (sometimes bloody), fever, and stomach cramps. #SketchyMicro #SketchyMicro::Bacteria::(05)-Gram_(-)_Bacilli-GI::5.03-Shigella $$Bacteria $Gram_(-)_Bacilli-Enteric Shigella bacteria cause an infection called shigellosis. Name 3 enteric bacteria with Type III secretion systems Also associated with Reitter's syndrome.) What type of diarrhea does Shigella cause?Ĭhildren <10 years old(Due to Shigella DYSENTERIAE.
