Porcine abortions associated with Fungi, Actinomycetes, and Rhodococcus sp.

Abstract

History, lesions, and results of microbiologic examinations are given for four porcine abortions associated with fungi and one each associated with Actinomadura madurae, an aerobic actinomycete, and Rhodococcus sp. The fungi were Gliomastix sp., Petriellidium boydii, Aspergillus fumigatus, and Exophiala jeanselmei. Parvovirus, isolated from one fetus, was the only other infectious agent identified. The presence of fungi, Actinomadura madurae, and Rhodococcus sp. in fetal and placental lesions indicates that they are a primary cause of sporadic abortion in pigs.
