Thelazia nematodes cause ocular infection in several mammals and are transmitted by dipteran flies. Thelazia callipaeda Railliet and Henry 1910 (Spirurida, Thelaziidae) is common in the Far East, where it causes eyeworm infection in carnivores and humans. In the past few years, it has also been reported in dogs, cats and foxes in Northern and Southern Italy. Although a great deal of work has been carried out in China and other Eastern countries, knowledge of the morphology of T. callipaeda is scanty. Eighty-three nematodes collected from the eyes of naturally infected dogs from the Basilicata region (southern Italy) were examined by light and scanning electron microscopy, and the most important features of the nematodes were described. The morphological characteristics useful for the identification of T. callipaeda are discussed.

Abstract

Thelazia nematodes cause ocular infection in several mammals and are transmitted by dipteran flies. Thelazia callipaeda Railliet and Henry 1910 (Spirurida, Thelaziidae) is common in the Far East, where it causes eyeworm infection in carnivores and humans. In the past few years, it has also been reported in dogs, cats and foxes in Northern and Southern Italy. Although a great deal of work has been carried out in China and other Eastern countries, knowledge of the morphology of T. callipaeda is scanty. Eighty-three nematodes collected from the eyes of naturally infected dogs from the Basilicata region (southern Italy) were examined by light and scanning electron microscopy, and the most important features of the nematodes were described. The morphological characteristics useful for the identification of T. callipaeda are discussed.
