Chlamydia:
1. genome 2. type of organism 3. key feature from cell membrane 4. dependent on what from host? |
1. both DNA & RNA
2. obligate intracell bacteria 3. no PTG 4. need ATP from cell |
|
|
|
Review the life cycle of Chlamydia:
--which form is infectious? --which form is replicating? |
|
|
|
|
2 genuses of Chlamydiaceae and dz causing spp
|
Chlamydia: C. trachomatis
Chlamydophilia: C. psittaci, C. pneumoniae |
|
|
|
Chlamydia:
1. 3 parts to pathogenesis 2. Immunity? |
1. access through abrasions, significant cell damage, induce inflammatory response
2. not long lived |
|
|
|
Trachoma:
1. micro cause 2. organ affected, type of path 3. serotypes causing this dz |
1. Chlamydia trachomatis
2. eye, chronic follicular conjunctivitis leading to scarring & blindness 3. A, B, C (not found in US) |
|
|
|
5 types of infections caused by Chlamydia trachomatis
--which serotype(s) responsible? |
1. Trachoma (A-C)
2. Genital tract infection (D-K) 3. inclusion conjunctivitis (D-K) 4. neonatal pneumonia (D-K) 5. lymphogranuloma venereum (L) |
|
|
|
Chlamydia genital tract infection:
1. serotypes responsible 2. transmission, incubation 3. sxs in men (3), women (3), infants (1) |
1. D-K
2. sexually, 2-6wk incubation 3. (generally assympto in adults) --men: urethritis, epidymitis, prostatitis --women: cervicitis, salpingitis, PID (infertility) --infants: pneumonia |
|
|
|
Chlamydia inclusion conjunctivitis:
1. serotypes found 2. cause 3. contrast w/ trachoma |
1. D-K
2. contact w/ infected vaginal secretions 3. trachoma is caused by different serotypes (A-C) & more chronic dz; inclusion conjunctivitis is more acute |
|
|
|
Chlamydia lymphogranuloma venereum:
1. transmission 2. result 3. 2 parts to tx |
1. sexual
2. suppurative multilocular inguinal lymph nodes (bubos) forming: fistulas, strictures, abscesses 3. tetracycline, erthryomycin |
|
|
|
3 non-culture means of dx Chlamydia trachomatis
|
1. direct fluorescent Ab
2. lipopolysaccharide enzyme assay 3. DNA probe of rRNA (combined w/ gonococcal screen) |
|
|
|
4 ways to tx Chlamydia trachomatis
--which one for pregnant women? |
1. Tetracyclines
2. Quinolones 3. Azithromycin 4. Erythromycin (pregnant) |
|
|
|
Chlamydia pneumoniae:
1. 3 common clinical presentations 2. diagnosis 3. transmission |
1. pharyngitis, laryngitis, walking pneumonia
2. acute & convalescent serology 3. respiratory spread |
|
|
|
Chlamydia psittaci:
1. transmission 2. dz resulting |
1. zoonotic: inhale respiratory secretions or droppings of infected birds (all, especially parrots & parakeets)
2. severe lower respiratory tract infection: dry cough, B/L pneumonia, fever |
|
|
|
Mycoplasma pneumoniae:
1. describe membrane 2. requirement for growth 3. pathogenesis |
1. no cell wall, single triple layered sterol membrane
2. cholesterol for membrane 3. attaches to bronchial epithelium, inflammatory response (superAG) |
|
|
|
Mycoplasma pneumoniae:
--sxs --CXR finding |
|
|
|
|
4 uncommon dzs caused by Mycoplasma (NOT pneumonia)
|
1. dermatologic
2. cardiac 3. arthritis 4. neurologic |
