| re-evaluation of ivermectin efficacy against equine gastrointestinal parasites. | two trials were conducted to confirm the efficacy of ivermectin paste against endoparasites of horses. in these trials, 20 ponies were treated with ivermectin oral paste at 200 mcg x kg body weight once on day 0, and 20 ponies served as unmedicated controls. the animals carried naturally acquired parasite infections as confirmed by pretrial fecal examination. the animals were necropsied for worm recovery on days 14, 15 or 16. parasites recovered were identified to species. horses treated with iv ... | 2001 | 11423189 |
| biodiversity and distribution of helminths and protozoa in naturally infected horses from the biosphere reserve la sierra madre de chiapas", méxico. | a cross sectional survey was performed to identify gastrointestinal helminths and protozoans in naturally infected horses from the biosphere reserve known as "la sierra madre de chiapas", mexico (el triunfo and la sepultura). during a three-year survey, fecal samples from 90 horses and parasites from 2 necropsied animals were collected. five families from the nematoda class: ascaridae, kathlanidae, oxyuridae, strongylidae and trichostrongylidae were found, whereas, only one family from the class ... | 2010 | 20307938 |
| morphology and differential diagnostics of parasitic larvae of some strongylidae (nematoda) of horses. | the morphology of l4 of cylicostephanus minutus, cylicotetrapedon bidentatus, petrovinema poculatum, cylicocyclus radiatus, c. triramosus, cylicodontophorus euproctus, c. mettami, c. mongolicus, poteriostomum imparidentatum, gyalocephalus capitatus and craterostomum acuticaudatum is discussed. the species are named in accordance with the new system, which is outlined in the introduction. the criteria for the identification of larvae killed during their 4th skinning include distinctive marks occu ... | 1990 | 2337250 |
| in vitro development of cyathostomin larvae from the third stage larvae to the fourth stage: morphologic characterization, effects of refrigeration, and species-specific patterns. | a mixed population of equine cyathostomin (nematoda, strongyloidea) infective third stage larvae (l3) was cultured in vitro using a cell-free medium. some l3 were cultured immediately after baermann collection from fecal cultures, while others were kept in water at 4 degrees c for 7 days before initiating the in vitro cultures. cultures were examined daily for viability. at days 2, 7, 14 and 21 larvae were collected for identification of developmental stage and morphological changes, using both ... | 2009 | 19493623 |
| phylogenetic analysis of the genus cylicocyclus (nematoda: strongylidae) based on nuclear ribosomal sequence data. | seven species of cylicocyclus ihle, 1922 (nematoda: strongylidae) were collected from donkeys from henan province, china. five samples of each species were selected for sequencing. sixteen different internal transcribed spacer (its) sequences representing the seven species of cylicocyclus were obtained. sequence differences in the first internal transcribed spacer (its-1) among species was lower than that of the second internal transcribed spacer (its-2). phylogenetic analyses were conducted usi ... | 2013 | 23666651 |
| cyathostominae (nematoda) parasites of equus caballus in some brazilian states. | thirty six horses from nine brazilian states (goiás, minas gerais, pará, maranhão, piauí, paraíba, pernambuco, rio grande do norte, and ceará) were examined for infections by small strongyles. the following species were identified: cylicocyclus nassatus, c. insigne, c. brevicapsulatus, c. leptostomum, c. radiatus, c. ultrajectinus, c. ashworthi, cylicostephanus goldi, c. calicatus, c. minutus, c. longibursatus, petrovinema poculatum, coronocyclus coronatus, c. labiatus, c. labratus, cyathostomum ... | 1999 | 10489198 |
