All clinical isolates grew on Ashdown’s medium and were gram-negative, bi-polar staining bacilli. Each isolate was oxidase positive, citrate positive and motile. Each isolate produced alkaline reactions on TSI and was violet on LIA in addition to being negative for Indole, H2S and gas production. For AST testing, the concentration (μg) of the antibiotic disk is in parentheses next to the antibiotic name. The zone of inhibition (mm) for each antibiotic is indicated in parentheses next to its results: S, Sensitive; R, Resistant. # denotes sputum culture was plated directly onto Ashdown’s Agar. Cultures were collected at admission unless otherwise indicated (*+1 day, ***+3days). Remaining Time to culture positive results indicate blood culture bottle positive.
