ABSTRACT
Placentitis, premature birth, and perinatal death were associated with Encephalitozoon cuniculi infection in an alpaca. Histologically, chorionic trophoblasts contained many Gram-positive, period acid-Schiff positive, variably acid-fast spores. Multifocal necrosis and infiltration by lymphocytes, eosinophils, and neutrophils were scattered throughout the chorionic membrane. Spores in trophoblasts were approximately 1 microm x 2 microm, thick-walled, and contained polar filaments and polar vacuoles consistent with microsporidia. The presence of E. cuniculi DNA was confirmed by sequencing the polymerase chain reaction amplicon from frozen placental tissue. A few glial nodules were scattered throughout the cerebrum, and mild lymphocytic inflammation was present in the heart, liver, and lung. No organisms were detected in tissues other than the placenta. This is the first reported case of E. cuniculi infection in an alpaca.
