| scanning electron microscopy of strongylus spp. in zebra. | the external ultrastructure of the anterior and posterior extremities of the nematodes, strongylus asini , strongylus vulgaris, strongylus equinus and strongylus edentatus, was studied with scanning electron microscopy (sem). fresh specimens of s. asini were collected from the caecum, ventral colon and vena portae of equus burchelli and equus zebra hartmannae ; s. vulgaris from the caecum, colon and arteria ileocolica of e. burchelli ; s. equinus from the ventral colon of e. z. hartmannae and s. ... | 1983 | 6676687 |
| studies on strongylus asini. i. experimental infestation of equines. | infective larvae were harvested from a culture of eggs collected from adult strongylus asini recovered from a free-ranging burchell's zebra, equus burchelli, in the kruger national park. worm-free zebra, horse and donkey foals were successfully infested, but infestation failed in a mule foal. at slaughter, 117-125 days post-infestation, s. asini in their 4th moult were recovered from the liver and portal veins. this is the first report of successful experimental infestation of these hosts with s ... | 1982 | 7177594 |
