Clap and Mycoplasma Flashcards
Chlamydia Facts (6)
Obligate intracellular parasites with spore-like extracellular forms
Cant make ATP, has DNA and RAN
Human to human transmission
Multiply in inclusion bodies (in cytoplasms if host)
Target columnar epi
Non peptidoglycan layer
3 types of clap
C. trachoma’s
C. pneumonia
C. psittaci
All pirates of Chlam island
Clap into cells
elemental body (spore form), phagocytose, migrate to reticular body, multiply here making it in intermediate body, cell rupture and elemental body is release
Chlamydia trachoma’s
- clinical characteristics
- transmission
- Dx
- trx
Pirates of Chlam Island
- oculular trachoma(conjunctivas-blindness from scaring+inclusion conjunctiva (acute, adult/perinatal), infant pneumonia (staccato cough) when mom has infection, GU tract infection-urethritis and PID, Reactive arthritis (Reiter’s syndrome), lymphogranuloma venerum (increase HIV risk)
- STI often travels with N. gonnoreha
- PCR based urine test (NAAT)
- Topical macrolide (newborns need ora), tetracyclines, (and ceftriaxone if have gonorrhea)
Chlamdia pneumonia
- clinical characteristics
- transmission
- Dx
- trx
Pirates of Chlam Island
- Mild URI, atypical pneumonia
- ineffecient transfer by respiratory
- check for Ab
- doxycyline and if doesn’t work macrolide
Chlamydia psittaci
- clinical characteristics
- transmission
- Dx
- trx
Pirates of Chlam Island
- psittacosis or ornithosis (from birds), fever headache sore throat, atypical pneumonia
- inhalation of bacteria on feathers or feces, or infected poultry
- history
- Probably macrolide and doxy
Mycoplasma general facts-6
3 species-ureaplasma urealyticum, M. hominis, M. genitals (lock like fried egg)
- Men-urithritis, woman-bacterial vaginosis, cervicitis, PID
- Smallest free living orgs that can be cultured
- highly plieomorphic-no CW but 3 layers of PM (very resistant to Antibiotics)
- No gram stain
- fastidous-cholesterol in PM, need cholesterol to grow-grow slow
Atypical pneumonia facts (3)
incubation of 2-3 weeks (viral is 1-3 days)
gradual onset of fever, headache, cough (sloughing of bacterium into lung lumen)
cold agglutinations of IgM (lyses RBC)
-problems for sickle cell or splenectomy-get disease worse-possible digital necrosis
Mycoplasma pneumonia
- transmission
- virulence
- disease
- ID
- trx
Walking on Thin Ice
- repsitory droplets
- adhesion-high affinity for resp epi cell cola (CRITICAL FOR PATHOGENICITY), @ attachment lose cilia and cell sloughs into lumen=cough, H2O2 produced in other mech
- atylpical penuomina, URT
