| prevalence, abundance and site distribution of equine small strongyles in normandy, france. | forty-two horses from normandy (france) were examined post-mortem for small strongyle infections from october to march. in the positive horses, total worm numbers ranged from 234 to 90,247 (mean 11,297). encysted larvae represented the major part of the total cyathostome burdens with a high percentage (83%) being early third stage larvae. they were mostly recovered from the caecum (48%) and ventral colon (40%) and were less present in the dorsal colon (12%). adult cyathostomes were mainly locate ... | 2002 | 12446091 |
| field study on the efficacy of an oral 2% ivermectin formulation in horses. | twenty horses naturally infected with nematodes were included in a blind, controlled field study on efficacy and safety of an oral 2% ivermectin formulation at a dose of 0.2 mg.kg(-1). horses were divided into treated and non-treated (control) groups with ten animals each based on preliminary counts of eggs per gram of feces (epg). stool samples were collected after treatment for identification of nematode species. clinical evaluations and epg counts were performed on days 0, +5, +14 and +19. ni ... | 2011 | 21722495 |
| 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 |
