background: infectivity of herbivores with trichostrongylus nematodes is widespread in many countries, having a major economic impact on breeding, survivability, and productivity of domestic livestock. this study was carried out on trichostrongylus species isolated from domestic livestock in order to develop an easy-to-perform method for species identification. methods: trichostrongylus isolate...

The present study was performed to analyze molecularly the phylogenetic positions of human-infecting Trichostrongylus species in Mazandaran Province, Iran, which is an endemic area for trichostrongyliasis. DNA from 7 Trichostrongylus infected stool samples were extracted by using in-house (IH) method. PCR amplification of ITS2-rDNA region was performed, and products were sequenced. Phylogenetic...

Worm-free Merino yearlings were dosed with either a mixture of infective larvae of Trichostrongylus axei and Ostertagia circumcincta or with O. circumcincta only, and challenged 90-93 days later with infective larvae of Haemonchus contortus. Neither of these methods protected sheep against challenged and slight protection was afforded sheep predosed with T. axei and O. circumcincta and challeng...

BACKGROUND Infection with Trichostrongylus spp. is common among human and herbivorous in most parts of Iran, especially in southern and northern areas. The aim of present study was to identify Trichostrongylus spp. among human population using excreted egg specimens, by the molecular method, in Mazandaran Province, northern Iran. METHODS Overall, 33 positive fecal specimens were randomly samp...

The helminths of 3 blue duikers, Cephalophus monticola, from 3 nature reserves in Natal were collected, counted and identified. Taenia hydatigena larvae, a race of Cooperia rotundispiculum, gongylonema angistris, Trichostrongylus falculatus and Trichostrongylus rugatus appear to be new parasite records for blue duikers in South Africa.

The helminths of 4 suni, Neotragus moschatus, from the Tembe National Elephant Park, KwaZulu, Natal, were collected, counted and identified. Cooperia hungi, a race of Cooperia rotundispiculum, Haemonchus vegliai, Setaria cornuta, a Skrjabinema sp., Strongyloides papillosus, Trichostrongylus anomalus and Trichostrongylus deflexus are new parasite records for suni in Africa. Megacooperia woodford...

Sixteen grey duikers were culled on the farm Riekert 's Laager in the central Transvaal at irregular intervals from May 1979-March 1981. One trematode species, 3 cestode species and 16 nematode species were recovered from these animals. Of these the following are new helminth records for this antelope: Cooperia hungi , Cooperia neitzi , Cooperia pectinata , Trichostrongylus axei, Trichostrongyl...

Resistance to benzimidazoles (BZs) in trichostrongyloid nematodes is a worldwide problem for livestock production, particularly regarding small ruminants. Sensitive and reliable methods are required to assess anthelmintic resistance status. Currently available methods for BZ resistance detection can be divided into three main groups, in vivo (e.g. faecal egg count reduction test), in vitro (e.g...

Helminth parasites were collected from 13 grysbok, Raphicerus melanotis, 12 common duikers, Sylvicapra grimmia, 24 Angora goats and 24 Boer goats killed on a farm in Valley Bushveld in the eastern Cape Province. Nematodes belonging to 9 species and a further 2 genera and cestodes belonging to 1 species and a further genus were recovered from the grysbok. Of these, worms of the genus Skrjabinema...

Three species of trichostrongylid nematodes; Trichostrongylus colubri-fonnis (GILES, 1892), Impalaia tuberculata MONNIG, 1923 and Paraheligmonel-loides kenyensis gen. et sp. n. are described. All worms were found in the small intestines of the Pronolagus sp. from Kenya. This is the first record of parasitic nematodes from the genus Pronolagus. 1. tuberculata is the first record of the genus Imp...
