The postmortem diagnosis of an Armillifer infection case in a cynomolgus macaque (Macaca fascicularis).

Armillifer moniliformis belongs to the order Porocephalida and family Porocephalidae, and it can cause zoonotic pentastomiasis. A suspected parasitic infection was incidentally discovered in the abdominal cavity of a cynomolgus macaque that died of persistent diarrhea. 18S rDNA amplification and sequencing revealed a high similarity (99.83%) to the Armillifer moniliformis Guangxi isolate. The isolated parasite was named the Armillifer moniliformis Yunnan isolate (GenBank accession no. HM048870). Our report presents a case of Armillifer moniliformis infection in macaques. The results indicated that early quarantine and diagnosis should be employed for animal health.
