Studies on Haemonchus contortus. X. The effect of Trichostrongylus axei in Merinos on artificial pastures.

A recently established Eragrostis curvula pasture 1,1 ha in size at Hennops River in the Transvaal Highveld was contaminated from 6 October 1976 until 20 May 1977 by 30 weaned Merinos, each infested with 7 000 infective larvae of H. contortus. On 2 November 1976 3 groups of weaned Merinos and again on 10 January 1977 a further group of Merinos were infested with 40 000 infective larvae of Trich...

Studies on Haemonchus contortus. XII. Effect of Trichostrongylus axei in Dorper lambs on natural pasture lightly infested with H. contortus.

Weaned Dorper lambs on natural pasture were predosed with 40 000 infective larvae (L3) of Trichostrongylus axei, irradiated (0,3 kGy) L3 of T. axei or closantel at 10 mg/kg either in September or November 1978 and were compared with Merino yearlings predosed with 40 000 L3 of T. axei in November 1977. The following summer (December-March) only 178,6 mm of rain fell and very few H. contortus wer...

Trichostrongylus Infection in Man

Three trichostrongylid nematodes from the red rock rabbits, Pronolagus sp., in Kenya.

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...

Studies on Haemonchus contortus. XI. The effect of a bovine strain of Trichostrongylus axei in Merinos on natural pastures heavily infested with H. contortus.

Sheep grazed on natural pastures heavily infested with infective larvae of Haemonchus contortus. Sixty-eight weaned Merinos were divided into 6 groups on Day 0 (23 November 1977), and on Day +14 (7 December) 79 Merinos were divided into 7 groups. There were 2 groups of undosed controls and other groups were either dosed with infective larvae of Trichostrongylus axei (bovine strain) only on Days...
