Document Summary
Lo2- identify the most likely pathogens that caused ab"s infection based on her initial presentation. Of these, the top 3 most commonly isolated pathogens are: streptococcus spp. , e. coli, b. fragilis. Bacteroides spp: morphology: bacillus (rod-shaped), can be motile or non-motile, non- endospore forming, anaerobic and gram-negative rod, family: bacteriodaceae, usual habitat in humans: colon and distal ileum, common infections caused by the pathogen: Septicemia: appropriate empiric antibiotic: metronidazole 500mg po q8h x 7-10 days (in severe infections: 7. 5mg/kg q6h, max 4g/day, mechanism of resistance: can mediate resistance** * can initiate abscess formation: anaerobes not usually cultured bc they don"t grow well in culture (must consider. Bacteroides=anaerobes); they are present in up to 70 % of cases: strep, e coli = baseline community acquired, hospital: enterococcus, enterobacter, pseudomonas, staph aureus. Lo3- list 4 appropriate antibiotic regimens for community acquired iai. Define the appropriate duration of therapy for this infection.
