Document Summary

Dull, glistening: what conclusions about bacteria species can be bade, e. coli. Not an enteric bacteria (gram +) o. If little or no growth- urine culture is considered (-) for pathogens and culture is complete: mac agar, growth gram (-) enteric . White colonies lac (cant use lactose) Blood agar (bap: most bacteria can grow, hemolytic bacteria lyse rbcs . Zone of inhibition: clear areas surrounding antibiotic discs. The greater the zone of inhibition- the more sensitive the bacteria to the antibiotic. Factors that need to be considered in determining what antibiotics are chosen to treat bacterial infections o o. Interactions with other medications: type of infection/ type of bacteria, cause of infection, toxicity, availability of antibiotic o. Probability of it affecting normal flora: medication cost to patient o. Side effects to patient: bacterial resistance o. Unsure of what the specific infection is and what is causing it (cause unknown: narrow spectrum.
