Effect of cyclophosphamide on experimental Nocardia asteroides infection in mice.

abstract：:Nonvertebrate model hosts represent valuable tools for the study of host-pathogen interactions because they facilitate the identification of bacterial virulence factors and allow the discovery of novel components involved in host innate immune responses. In this report, we determined that the greater wax moth caterpil...
