2.2 Bacteria Flashcards
Why must you always take the full dosage of an antibiotic if you start?
- typically don’t completely kill the bacteria, but kills enough so your immune system can finish the job
- haven’t shrunk bacterial load down enough for immune system to kill
- bacteria mutates to compensate
Are probiotics a good idea?
- can help if you take the right type
- must be coated to make it through the GI tract
When is fecal transplant a good option?
- gets rid of c-diff quickly
- way to get normal flora back to a patient
Where do fecal transplants typically come from?
family members
common bacteria
- TB
- bacterial pneumonia
- streptococcus
- c-dif
What are some of the resistant bugs?
- MRSA
- VRE
- TB
getting rid of MRSA
- typically has to run its course
- not much to get rid of it
use of vancomycin for MRSA
now we have VRSA and MVRSA
Why do we get resistant strains of bacteria?
- massive antibiotic usage
- doesn’t take a lot of time
Which of the resistant bacteria requires a long course of drugs?
TB
Why does TB require a long course of drugs?
- takes a long time to get it under control
- body never really gets rid of it
- growth just slows down enough so the body forgets about it
the body typically ____ TB bacteria
encapsulates
Where do most fungi come from?
dirt
common fungi
- tinea pedis
- tinea corpos/capitus
- candidiasis
- cryptococcal meningitis
- PCP
tinea pedis
athlete’s foot
tinea corpos
ringwork
candidiasis
yeast infections
types of candidiasis infections
- vaginal (vaginitis)
- oral (thrush)
- foreskin (balanitis)
- skin folds
Who is particularly susceptible to yeast infections?
- obese people with poor hygiene
- people on antibiotics
Why do antibiotics put you at risk for yeast infections?
normal bacteria keeps yeast away
treatment for yeast infections
- OTC topicals (vaginal, foreskin)
- oral rinse (thrush)
- keep as dry as possible
Who often gets thrush?
- immunocompromised
- babies
Who gets cryptococcal meningitis?
- immunocompromized
- HIV/AIDS
What does cryptococcal meningitis cause?
- inflammation of the meninges
- neurological problems
PCP
pneumocytis pneumonia
Who gets PCP?
HIV/AIDS
immunocompromised
What can result from long term antifungal use?
bad side effects on the liver
Why do fungal meds often have bad side effects?
our cells are similar (eukaryotic)
