Assessment of cellular invasion potential of different isolates of Staphlococcus xylosus by using NIH 3T3 cells as targets. The isolates characterized included 2 S. xylosus isolates from ATCC (one from an outdoor botanical garden and one from the surface of human skin); 3 isolates from field cases of UD from C57BL/6 mice; and an isolate from UD in a SCD1 ^–/– mouse. Letters denote significant differences in cell invasiveness as follows: a > b > c. Statistical significance was defined as a P value of 0.05 or less (Mann–Whitney test).
