a + = Culture was correctly identified by the collaborating laboratory. b CBA = Columbia agar with 5% sheep blood, TSA = Trypticase soy agar, TSAB = Trypticase soy agar with 5% sheep blood. c Low discrimination between L. innocua/L.welshimeri reported by VITEK 2; supplemental tests were conducted to report final identification. d Low discrimination between L.seeligeri/ivanovii/welshimeri reported by VITEK 2; supplemental tests were conducted to report final identification. e NT = Not tested. Isolate was not identified as Gram positive and thus not tested on the VITEK 2 GP card. f Low discrimination between S. aureus/S. intermedius reported by VITEK 2; supplemental tests were conducted to report final identification.
