YBX3 and infection: Many lipoproteins critical for infection of the mammalian host, i.e., DbpA, BBK32, and OspC were elevated with the increased RpoS and CsrABb with increased added acetate under temperature and pH conditions mimicking the fed-tick, laboratory, or unfed tick (Figs. 6F, 7F, 8F; α-DbpA, α-BBK32, α-OspC).
