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...

A three-year survey (1997-99) was carried out on organically reared sheep flocks throughout Sweden. The aim was to determine the prevalence and intensity of nematode infections and to establish relationships between sheep management practices and parasite infections. Faecal samples from ewes and lambs were collected from 152 organic flocks around lambing-time and during the grazing-period for a...

A total of 133 (65.51%) faecal samples were found positive for various helminths and most frequently strongyle infections were diagnosed with an infection rate of 58.5% (117/200) in a year long study to asses various epidemiological factors influencing the gastro-intestinal nematodes of horses. Significant difference in the prevalence of various gastrointestinal helminths was detected in the st...

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...

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...

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...

Soon after 12-week old suckling lambs reached a peak infestation of Nematodirus resistance developed, worm burdens falling by 43.1-97.5% in 18 week and 11-month old sheep respectively. Both Teladorsagia (syn. Ostertagia) and Trichostrongylus reached a peak geometric mean (G) of 18,099 and 3,278 worms on 02 December 1987 in weaners 5-6 months old. Within 6 weeks-6 months of sheep grazing on safe...
