There were six other mixed cultures that did not contain resistant organisms. CNStaph, coagulase-negative staphylococcus; Oxa, oxacillin.

E. faecalis and S. aureus were phenotypically Tet^s. K. pneumoniae was not tested.

These CNStaph isolates were oxacillin resistant, but PCR-LDR did not detect mecA or staphylococcal 16S rRNA gene sequences, presumably due to small numbers of organisms.
