| 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 |
| strongylus asini (nematoda, strongyloidea): genetic relationships with other strongylus species determined by ribosomal dna. | genomic dna was isolated from adult strongylus asini collected from zebra. the second ribosomal transcribed spacer (its-2) was amplified and sequenced using polymerase chain reaction (pcr) based techniques. the dna sequence was compared with previously published data for 3 related strongylus species. a pcr-linked restriction fragment length polymorphism method allowed the 4 species to be differentiated unequivocally. the its-2 sequence of s. asini was found to be more similar to those of s. eden ... | 1996 | 9024894 |
