Abstract

Subcutaneous vaccination with recombinant antigen 2/PRA (rAg2/PRA) protected BALB/c mice against intranasal infection with Coccidioides immitis. Subcutaneously vaccinated C57BL/6 mice and intranasally vaccinated BALB/c mice were protected against larger numbers of infecting spores. Weight loss correlated with lethality, but histologic appearance did not. These studies support rAg2/PRA vaccination to prevent coccidioidomycosis.

摘要

用重组抗原2/球孢子菌病抗原(rAg2/PRA)进行皮下接种可保护BALB/c小鼠免受鼻内感染粗球孢子菌。皮下接种的C57BL/6小鼠和鼻内接种的BALB/c小鼠能抵御更多数量的感染性孢子。体重减轻与致死率相关,但组织学表现并非如此。这些研究支持使用rAg2/PRA疫苗接种来预防球孢子菌病。
