| expulsion of small strongyle nematodes (cyathostomin spp) following deworming of horses on a stud farm in sweden. | this study was conducted on a stud farm in sweden to investigate the species composition of cyathostomins expelled in the faeces of horses after deworming using three different anthelmintic preparations. twenty-seven horses excreting > or = 200 strongyle eggs per gram faeces (epg) were divided into three comparable groups and dewormed on day 0 with either of following compounds: 0.2 mg ivermectin per kg body weight (bw), 19 mg pyrantel pamoate per kg bw or 7.5 mg fenbendazole per kg bw. for each ... | 2003 | 12944042 |
| study (1991 to 2001) of drug-resistant population b small strongyles in critical tests in horses in kentucky at the termination of a 40-year investigation. | population b, drug-resistant small strongyles have been studied in naturally infected horses in kentucky for more than 40 years. these parasites first were found to be resistant to phenothiazine (ptz) and thiabendazole (tbz), later to other parasiticides. studies have been on evaluation of antiparasitic efficacy of several compounds, especially the benzimidazoles, against population b small strongyles in clinical (field) tests (1959-1983) on the commercial farm of origin and in clinical and crit ... | 2007 | 17468973 |
| efficacy of an in-feed formulation containing ivermectin for the control of intestinal strongyles in captive zebras (equus burchelli (gray, 1824)). | the efficacy of medicated food pellets (containing 10mg of ivermectin per kg, unifeed, veronesi, verona, italy) was evaluated for the control of intestinal strongyles in a group of captive zebras (equus burchelli) at the safari park, fasano (apulia region, brindisi province, southern italy). the egg reappearance period and the faecal egg counts in terms of eggs per gram of faeces were investigated. from day 0 until day +9, 30 zebras were fed with medicated pellets and pooled faecal samples were ... | 2010 | 20071086 |
