On a urine bacteriology culture blood agar plate at 24 hours, over 100,000 small, white colonies are observed. They are catalase positive and a side coagulase test s negative. Your next step is to A) report out over 1000,000 staphylococcus epidermidis/ml of urine B) Perform a Gram stain C) Inoculate a Gram positive urine antibiotic susceptibility battery D) set up a tube E) ask for a repeat culture. Many fungal infections in oral pharyngeal, uro-gential and similar cultures are often...
please help me. answer only first page. thank you! p.
