This study describes the first record of Globocephalus samoensis (Nematoda: Ancylostomatidae) recovered in wild boars from southwestern regions of Korea. Gastrointestinal tracts of 111 Korean wild boars (Sus scrofa coreanus) hunted from mountains in Suncheon-si, Gwangyang-si, and Boseong-gun between 2009 and 2012 were examined for their visceral helminths. G. samoensis, as identified by morphological characteristics of the head and tail, were recovered from the small intestine of 51 (45.9%) wild boars. Worms were found from 7 of 28 wild boars (25.0%) from Suncheon-si, 40 of 79 (50.6%) from Gwangyang-si, and all 4 (100%) from Boseong-gun. The length of adult females was 7.2+/-0.5 mm, and the thickest part of the body measured the average 0.47+/-0.03 mm, while those of males were 6.52+/-0.19 and 0.37+/-0.02 mm, respectively. The buccal cavity was equipped with a pair of large and bicuspid subventral lancets near the base of the capsule. The average length of spicules of males was 0.45+/-0.02 mm. By the present study, G. samoensis is recorded for the first time in southwestern regions of Korea. Additionally, morphological characteristics and identification keys provided in the present study will be helpful in the faunistic and taxonomic studies for strongylid nematodes in both domestic and wild pigs. The infection of G. samoensis apparently did not elicit pathologic lesions, as revealed by macroscopic observation during the autopsy of all wild boars in this study.

Parasites were collected from 20 Burchell's zebra, Equus burchelli antiquorum, from Isiolo district, Kenya. 10 were ranched animals from the Lewa Downs Ranch and 10 free ranging from the areas adjacent to the ranch to the north. The animals were culled from 4th to 18th June 1995. The gastrointestinal tract was removed from the carcass and separated as stomach, small and large intestines and searched for parasites. The abdominal cavity was scrutinized for Setaria species. The parasites were identified to genus and in some cases species level. All animals were infected with at least three genera of parasites of which at least one genus was a nematode. A total of 10 genera representing eight families were recovered from the two groups. These included six nematode families, Strongylidae, Atractidae, Oxyuridae, Spiruridae, Setariidae, and Ascaridae, one cestode family, Anoplocephalidae and one family of the larvae of Gasterophilus bot flies, Gasterophilidae. The most prevalent families were Atractidae (100%) and Gasterophilidae (100%). The principle nematode genera was Crossocephalus whose total burden, plus or minus the standard deviation, was 3,471,129 +/- 1,352,922. Setaria species were recovered from the abdominal cavity of 45% of all the animals examined. The overall total worm burden was higher in the free ranging zebra 2,743,410 +/- 849,604 than the ranched zebra, 787,669 +/- 246,006. The range of individual genera varied from 0 to 269,225 in the free ranging group, which was higher than 0 to 77,890 in the ranched animals. From statistical analysis, no significant difference could be found between males and females. However, the burdens of genera Strongylus, Triodontophorus, Crossocephalus and Parascaris were significantly higher in free ranging animals.
