The numbers of individual Setaria species in the peritoneal cavities of Korean cattle were estimated. The worms were tentatively identified under light microscopy, and then precisely classified by SEM on the basis of unique features at the anterior and posterior ends of the adult worms. The positive rate of Setaria species was 34.2% out of 1,074 Korean cattle surveyed; that of S. digitata was 25.1%, S. marshalli 2.9% and both species 6.2%, respectively. Out of a total of 1,254 worms collected, 66.8% were female and 19.1% were male S. digitota; 9.2% were female and 5.0% were male S. marshalli, respectively. The average length of S. marshalli was somewhat longer than that of S. digitota S. marshalli was documented for the first time in Korea.

A total of 50 filariid worms of Setnria sap. was recovered from the peritoneal cavity of three neonatal calves infected with the Akabane virus. The parasites were identified as S. marshnlli by their morphological characteristics. Males were 41-52 mm long and females 68-98 mm. Most of them were fully matured, indicating that the calves were infected prenatally. This is the first report of prenatal infection in calves by S. marshnlli in Korea.
