Gonorrhea lol and enteropathogenic infections Flashcards
What infections does Gonorrhea cause
endocervicitis in women
urethritis in men
Who is more symptomatic with gonorrhea infection?
men usually - purulent discharge
Bacteriology of E coli ?
facultative aerobic gram -
ferments lactose
What is the appearance of E coli on EMB agar
metallic green sheen
Ecoli is the most common cause of what two diseases?
UTI and septicemia
In neonates ecoli is the second most common cause of septicemia after what other infection?
group B strep
Describe disease with ETEC?
Travelers diarrea - watery
Describe disease with EIEC?
invasive - bloody diarrhea
Describe disease with EHEC? What toxin causes the symptoms?
adults - mild bloody
kids - HUS - think post cheeseburger eating
-shiga toxin
NO Fever, PMNs or pus - noninvasive
What is the usual serotype that causes EHEC?
O157, H7
What is the treatment for EHEC?
supportive care ONLY
antibiotics are contraindicated
Bacteriology of salmonella
gram - rod
facultative anaerobe
nonlactose fermenting
How can we remember that salmonella is motile?
“salmon swim upstream” - they have flagella
What is the classic rash that occurs in typhoid fever?
rose spots
Salmonella is the most common cause of osteomyelitis in what group of patients?
sickle cell patients
What is the most common cause of bacterial gastroenteritis in the us? food poisoning?
gastroenteritis: campylobacter
food poisoning: C perfiringens
Remind me again how we differentiate the enterobacteria (using lactose, H2S, motile)
Lactose fermenters: E coli, Klebsiella
Nonlactose fermenters:
Non motile, non h2S producers: shigella, yersinia
Motile, H2S producers: salmonella, proteus
What is special about shigella in comparison to salmonella and ecoli?
low infectious dose required - acid resistant
What pathogen causes rice water stools
cholera
bacteriology of cholera
curved gram negative rods
oxidase positive
bacteriology of campylobacter
curved gram negative rods
oxidase positive
What is the reservoir for campylobacter
poultry
What are some post-infective complications of campylobacter
- GBS
2. reactive arthritis
