Abstract Background Coccidioidomycosis or Valley Fever is caused by Coccidioides in Southwest US and Central America. Primary pulmonary infection is initiated by inhalation of air-borne arthroconidia. Since lung is the first organ that encounters arthroconidia different components of the pulmonary innate immune system may be involved in the regulation of host defense. Pulmonary surfactant proteins SP -A and SP-D have been recognized to play an important role in binding and phagocytosis of various microorganisms but their roles in Coccidioides infection are not known. Methods In this study we studied the changes in amounts of pulmonary SP-A SP-D and phospholipid in murine model of Coccidioides posadasii infection and binding of SP-A and SP-D to .
