Abscess size and colonization of catheters according to dose of three Staphylococcus epidermidis strains in inbred C57BL/6JCrl , outbred Crl:CD1(ICR), and inbred BALB/cAnNCrl mice#.
four 8–12 week old male mice per bacterial- dose and phenotype were used.*
CFUs: colony-forming unit,‡
SEM: standard error of the mean,§
WT: wild type,£
hemB: hemB knock-out mutant with small-colony-variant phenotype,+
CM: complemented mutant of S. epidermidis hemB.a–c
Values with different superscripts within a row, assigned to the same infectious dose, and separated between abscess size and colonization vary significantly (p<0.05; Student's unpaired t-test).
