From: Biovar-related differences apparent in the flea foregut colonization phenotype of distinct Yersinia pestis strains do not impact transmission efficiency

Fig. 3

KIM6+, CO92, and CO92gly are transmitted from infected fleas at similar efficiencies. Yersinia pestis CFU transmitted by X. cheopis infected with KIM6+ (black triangles), CO92 (pink circles), and CO92gly (teal squares) during in vitro mass transmission experiments, per blocked flea bite (total number of transmitted CFUs/ number of blocked fleas) (a) and per infected flea bite (total number of transmitted CFUs/[number of fed fleas × % infected fleas]) (b). Fleas were fed on mouse blood seeded with ~109Y. pestis CFU/ml and were subjected to mass artificial transmission experiments 7 and 14 days after a single infectious blood meal. Symbols represent three independent experiments for KIM6+ and CO92gly, and two independent experiments for CO92. No significant difference in CFU Y. pestis transmitted per blocked flea or per infected flea bite between strains was noted using one-way ANOVA analysis
