Case report: Abortion and disseminated infection by Coccidioides posadasii in an alpaca (Vicugna pacos) fetus in Southern California

Coccidioidomycosis is a fungal disease affecting humans and other mammals caused by the soil-dwelling fungi Coccidioides immitis and C. posadasii. Abortion due to Coccidioides spp. infection is rare in domestic animals and transplacental transmission is considered uncommon in women. This report describes a case of placental-fetal infection and abortion in an alpaca with disseminated C. posadasii infection. PCR amplification and DNA sequencing were used to confirm the etiology, C. posadasii, in fetal tissues.
