We assessed thermotolerance by exposing individuals to temperatures between 14°C and 31°C and determining the temperature lethal to 50% of individuals (LT(50)) after a 24 hour exposure. …”

METHODS: Prevalence of antibodies against WNV was monitored weekly in House Finches and House Sparrows. …”

Three different adjuvant classes (nonionic surfactants, crop oil concentrates, and organosilicone surfactants) were investigated in this study. …”
