Seasonal density of trichostrongylid nematode larvae was investigated on a pasture used for communal grazing of livestock, using standard procedure of pasture larval count. For this purpose, herbage samples were collected from a posture near Faisalabad at fortnightly intervals over a 12 month period from July 2000 to June 2001. The larvae of Haemonchus (H) contortus, Trichostrongylus species, O...

background: to use different methods for serodiagnosis of ruminants' haemonchosis is important because detection of egg in the faeces is not so reliable. methods: peptide bands of 5 different crude antigens of intestine, uterus, cuticle, whole male and whole female of hae­monchus contortus were determined using sds-page and western blotting. five lambs were infected with 10,000 third stage larv...

ABSTRAK Kiraan telur cadng dalam najis dan kehadiran spesis-spesis nematod pada kambing daripada tujuh kandang kambing yang kedl di daerah Timur Laut, Pulau Pinang telah dikaji. Secara amnya kiraan telur adalah tinggi, berjulat antara 500 2000 epg. Keadaan iklim didaerah ini adalah sesuai bagi kehidupan dan perkembangan sekurang-kurangnya lima spesis nematod iaitu Cooperia spp., Haemonchus spp....

The prevalence of gastrointestinal (GI) parasites and the efficacy of Dectomax (Doramectin) against these parasites was studied. For this purpose, 50 camels were selected from different localities of Faisalabad, their faecal samples were collected and examined for the parasitism. The overall prevalence of G1 parasites was 60%. Species wise prevalence of these parasites was: 20, 14, 8, 4, 4 and ...

Excretory/Secretory antigen was prepared by culturing live adult worms of Haemonchus contortus in RPMI 1640 medium at a concentration of 50 worms per mL in a culture-flask at 37 ˚C for 24 hr and the culture supernatant was used as antigen. The E/S antigen was purified by thiol-sepharose affinity chromatography. On western blot analysis, it was demonstrated that thiol-purified antigen showed a s...

Fifty-thousand infective larvae of Trichostrongylus axei dosed to 7-9-month-old Merinos protected them against a subsequent challenge with 50 000 infective larvae of Haemonchus contortus. Protection varied with the period between an initial dosage of T. axei and challenge with H. contortus as follows: After 90 days it was more than 80% effective in more than 80% of sheep; at 119 and 180 days th...

A field program to control multiple anthelmintic resistant worm infections in cattle of Argentina is described. In 2003 around 140 calves died as a consequence of high worm burdens despite the administration of monthly alternate treatments with ivermectin (IVM) or fenbendazole (FBZ). A fecal egg count reduction test (FECRT) showed a clinical efficacy of 73%, 49.1% and 90.4% for IVM, FBZ and lev...

Two doses of infective larvae of 20 000 Trichostrongylus axei, dosed to Merino lambs at an interval of 14 days and subsequently challenged with Ostertagia circumcincta, caused a significant reduction (P less than 0.01) in the establishment of 5th and adult stages of the latter. T. axei was unable to protect Merino sheep against homologous challenge nor was Haemonchus contortus a successful vacc...

Helminth parasites were collected from 2 bushbuck, Tragelaphus scriptus, 2 red duiker, Cephalophus natalensis, 1 oribi, Ourebia ourebi, and 4 reedbuck, Redunca arundinum, that died or were culled in various parts of Natal. One trematode genus, 1 cestode genus and 12 nematode species were recovered. Haemonchus contortus. Ostertagia harrisi, Trichostrongylus capricola, Trichostrongylus vitrinus, ...
