We examined human keratinocyte cell invasion ability (CIA) of Pasteurella canis from 17 animals and 13 humans with relationships between CIA and host/genotypic traits. We designated CIA higher than isolate mean as high-frequency and that lower than mean as low-frequency. Repetitive element-based fingerprinting dendrograms were constructed; virulence-associated genes were clustered in phylogenetic trees. High-frequency CIA was observed in 9 isolates; low-frequency CIA in 21. No relationships were observed between high-frequency CIA and host/source. Dendrograms showed no associations between high-frequency CIA/host and different clades (A–1/–2; B–1/–2/–3). Trees with ptfAompA alleles showed no associations between high-frequency CIA/host and different clusters (1/2; 1/2/3). Our observations suggest CIA assessment feasibility without relationships between high-frequency CIA and host/genotypic traits.
