Detection of Diplotriaena spp. from the body cavity of Myna (Acridotheres tristis) in Mashhad, Iran

Abstract

A 23 year-old common Myna (Acridotheres tristis) was presented for autopsy to Veterinary Teaching<br><br>Hospital, School of Veterinary Medicine, Ferdowsi University of Mashhad. The history presented by the owner<br><br>revealed that the bird was caged alone; its diet consisted of commercial chicken layer’s pellets, fruits and<br><br>vegetables. There was not any history of any diseases before that owner found her dead in the floor of its cage in<br><br>the morning. Necropsy was done and revealed no gross pathological changes in visceral organs but in abdomen<br><br>cavity we found few nematodes. The nematodes that were collected in this case were identified as Diplotriaena<br><br>spp. The nematodes measured 10-15 mm x 0.75-0.80 mm, were milky white; the body was long and slender,<br><br>mouth simple without lips. A pair of chitinous tridents (0.145-0.155 mm) was noted at the head end of the worm.<br><br>Eggs were oval, thick shelled, smooth measuring 50 x 25 μm and embryonated. It is the first time in Iran when<br><br>this nematode was recovered from a Myna.
