Bacterial samples obtained from swab of wad staff equipment and surfaces arr brought to the lab for analysis. 1. What testing method will you employ to determine the level of exposure? 2 How would a positive test present? 3. How would a negative test present? 4. What recommendations would you make in your report?A patient suspected to have a UTI infection had a metallic green growth on EMB agar and also had positive culture on blood agar plates. The patient was most likely infected with: Klebsiella E.coli Proteus mirabilis Enterobacter Staphylococcus saprophyticuschoose any microorganism except S. aureus (Staphylococcus aureus)
