8 latest update (71
questions fully
solved )
microbial infection - bacterial - answer single cell
microorganism, gram + (2 outer layers) or gram - (3 outer
layers)
bacterial wall differs in structure
bacili: elongated, or rod shaped
cocci: spherical
microbial infections - viruses - answer smallest pathogen,
toughest
microbial infections - fungi - answer yeasts or mold, infect
skin or subcutaneous tissue
antibiotic basics - bacteriostatic drugs - answer inhibit
growth of bacteria
antibiotic basics - bactericidal drugs - answer kill bacteria
, antibiotic basics - combinations - answer additive: effect is
sum of the 2 antibiotics
potentiative: one potentiates effects of the other
antagonist: if one bactericidal & one bacteriostatic,
desired effect is diminished
antibiotic basics - narrow spectrum - answer primarily
effective against one type
ex: penicillin, erthrymycin
antibiotic basics - broad spectrum - answer effective
against gram + or gram -
ex: tetracyclines, cephalosporins
antibiotic basics - antibiotic resistance - answer
overprescribing, not taking full course
antibiotic resistance - natural or inherent resistance -
answer occurs without previous exposure to antibacterial
drug
antibiotic resistance - acquired resistance - answer caused
by prior exposure to antibacterial (ex: MRSA resistant to
all PCN & most cephalosporins)
antibiotic resistance - cross resistance - answer when
antibiotics have similar actions (PCN & cephalosporins)
