Atypical Bacteria ! Flashcards
Name them Atypicals [4]
and their genus
- structural properties
- AB implications
1: Mycoplasma - NO CELL WALL
- Mycoplasma Pneumoniae
2: Chlamydia - YES CELL WALL but no Peptidoglycan;
- – hard to stain, classified as gram negs due to outer membrane, have LPS
- —– intracellular
- chlamydia trachomatis
- note cell wall agents all USELESS; Macrolides can
- PCCGP (GP being vancomycin)
3: Rickettsia
4: Legionella
M Pneumonia
- damage
- Cx
- Lab
- treatment
Atypical pneumonia AKA Walking pneumonia;
- Cx: SJS, hypersensitivity IV! alot of systemic also
- Lab: Empirical; otherwise NAT-PCR, serology for children need see increase;
- Treatment: non cell wall agents
- ML, TC, FQ
Name the atypical pneumonia causers [4]
- note mostly intracellular
- each give their properties
- Legionella pneumophila - INTRACELLULAR
- Mycoplasma Pneumoniae - only extracellular here
- Chlamydia pneumoniae - people to people
- Chlamydia psittaci - birds to mammals
Chlamydia
- name 3 genus
Chlamydia Trachomatis
Chlamydia Psittaci
Chlamydia Pneumoniae
Chlamydia Trachomatis
- diseases!!!
- LAB
Trachoma - eye disease - Serovar A-C
- corneal damage, scarring, blinding
- spread by fingers flies formites;
Lymphogranuloma venereum; L1 L2 L3 ulcerative disease of the genital area
- ulcers, elephantiasis, proctitis (from anal sex)
- elephantiasis is enlargement of body due to obstruction of lymphatic vessels
- regional lymphadenopathy
STD - Serovar D-K
- urethritis
Lab: NAT!!!, swabs
Top 2 causes of PID
- what else they cause?
Chlamydia Trachomatis
N. Gonorrhea
- both can cause ophthalmia neonatorum
Whats the deal w Rickettsia and Orientia
- SG which one
GNR
