“…It is possible that these early post infection changes may reflect the decreased feed intake that occurred in conjunction with the post infection period of pyrexia. Similar decreases were reported by Bueno et a/ (1979) and by Berry et a/ (1986). In both these studies, however, the experimental animals were not raised in a S. vulgaris-free environment and despite being parasite-free at the time of infection, may have had prior exposure to the parasite.…”

“…Several authors have noted a high correlation between intestinal spike burst activity and contraction of the bowel wall (Roger, Bardon and Ruckebusch 1985;Flatt, Brown and Summers 1986). Two previous studies, one utilising a mixture of small and large strongyles (Bueno, Ruckebusch and Dorchies 1979) and the other specifically S . vulgaris (Berry et a1 1986), identified changes in the myoelectrical activity of the ileo-caeco-colic region and the terminal ileum respectively, associated with parasite infection.…”

Summary The myoelectrical activity of the ileum, caecum and large colon was monitored from Ag‐AgCl bipolar recording electrodes in four conscious ‘parasite‐naive’ weanling foals. All foals were inoculated with 1000 infective 3rd‐stage Strongylus vulgaris larvae and alterations to the myoelectrical activity observed. The frequencies of caecal and colonic spike bursts increased significantly in all post infection periods coinciding with assumed larval penetration into the intestinal mucosa and migration through the vasculature. Peaks in caecal and colonic activity occurred at Days 1 to 5 post infection. In the caecum, peaks occurred again at Days 15 and 31 post infection, preceding similar rises in colonic spike burst frequency at Days 19 and 35. Longer term changes indicated a return towards pre‐infection levels of activity suggesting smooth muscle adaptation to decreased blood flow. The analysis of caecal and colonic spike burst propagation indicated that the increases in burst frequency were not attributable to an increase in the propagation of spike bursts in any particular direction, but rather to proportional increases in all directions of activity. There was a slight decrease in the simple ileal spike burst frequency immediately post‐infection. None of the experimental animals exhibited signs of abdominal pain during the trial, and there was no evidence of bowel infarction at post mortem examination despite the presence of severe parasite‐induced arterial lesions. The results suggest that increased caecal and colonic motility is an important host response in susceptible foals exposed to S. vulgaris larvae.

“…It is possible that the presence of large cyathostome populations in the control horses contributed to the large amounts of sand present in the large bowel of two of them. Bueno, Ruckebusch and Dorchies (1979) have demonstrated a reduced ileal and caeco-colic motility associated with cyathostome populations and this may be significant in EQUINE VETERINARY JOURNAL preventing the elimination of accidentally ingested sand. 'Sand colic' and sand impaction are significant gastrointestinal problems in horses in the Perth area.…”

Integrated control of Strongylus vulgaris infection in horses using ivermectin

Summary An attempt was made to control or eliminate Strongylus vulgaris from a closed group of three horses at pasture near Perth, Western Australia, by dosing with ivermectin on four occasions during the time of year when it was believed that environmental conditions would eliminate all the non‐parasitic stages of that species. At necropsy, five months after the last dose of anthelmintic and after continually grazing the same pastures, no S vulgaris or arterial lesions were found in those horses and S edentatus, Draschia megastoma and Habronema species were also almost completely eliminated.

“…Experimental infections with mixed strongyles have been demonstrated to cause changes in intestinal motility (Bueno et al 1979) and overt signs of colic Murphy and Love 1997). Some studies using 'mixed strongyle infections' included S. vulgaris in the infective dose which complicates interpretation.…”
