| gross and microscopic observations of ovarian abnormalities from five burchell's zebra, equus burchelli antiquorum, smith 1841. | five pair of zebra ovaries were submitted to the onderstepoort veterinary research institute for examination because of unusual uni- and/or bilateral gross appearances. microscopic findings revealed an accessory spleen encapsulated by the ovarian peritoneum, a case of tubo-ovarian cysts, one example of ovarian aplasia, an example of germinal inclusion cysts and an abnormal follicular haemorrhage related to pressure necrosis of a nearby corpus luteum. similarities to the ovary of the domestic mar ... | 1975 | 1221329 |
| the pattern of venous drainage of the equine ileocaecal junction. | the veins draining the ileocaecal junctions of horses (n = 19), donkeys (n = 3) and a plains zebra, (equus burchelli antiquorum) were injected with latex via the ileocolic vein, and dissected. in all specimens the ileocaecal papilla was drained by 2 major papillary veins: one cranial and one caudal to the papilla. a smaller dorsal vein drained either into the cranial or into the caudal vein. the submucosal veins seemed to increase in number in the ileocaeacal junction to form a venous plexus. th ... | 1988 | 3199408 |
| the arrangement of the muscle layers at the equine ileocaecal junction. | the muscle layers of the ileocaecal junctions of horses (n = 18), plains zebras (equus burchelli antiquorum) (n = 3), mountain zebras (equus zebra zebra) (n = 2), and a donkey were examined macroscopically and microscopically. the muscular tunic of the ileocaecal papilla was made up of 3 layers: an innermost circular layer which was a continuation of the circular muscle of the ileum, a central longitudinal layer which was a continuation of one part of the longitudinal layer of the ileum and an o ... | 1988 | 3392703 |
| studies on the parasites of zebras. iv. cylicodontophorus reineckei n.sp. (nematoda: strongylidae) from the burchell's zebra, equus burchelli antiquorum h. smith, 1841 and the mountain zebra, equus zebra hartmannae matschie, 1898. | a new species of nematode, cylicodontophorus reineckei, was collected from burchell's zebra, equus burchelli antiquorum h. smith, 1841, in both the etosha national and kruger national parks and from mountain zebra, equus zebra hartmannae matschie, 1898, in the namib naukluft park in south west africa/namibia. these nematodes have an external leaf-crown with longer elements than those of the internal leaf-crown and a well-developed dorsal gutter. the very well-developed oesophageal funnel is both ... | 1984 | 6533516 |

| characterization of the microbial community colonizing the anal and vulvar pores of helminths from the hindgut of zebras. | scanning and transmission electron microscopy were used to examine the adherence and in situ morphology of the microbial community colonizing the anal and vulvar pores of the subfamily cyathostominae (nematoda: strongylidae) from the colon of burchell's zebra (equus burchelli antiquorum). two different morphological types of asporogenous rod were prominent in the microbial community. one was a thin, septate, filamentous organism (0.4 to 0.5 micron by 2 to 3 microns) with blunt ends, which was mo ... | 1989 | 2667460 |
| echinococcosis (hydatodosis) in wild animals of the kruger national park. | echinococcosis has been diagnosed in the following wild species in the kruger national park : lion, panthera leo, spotted hyena, crocuta crocuta, cape hunting dog, lycaon pictus, burchell's zebra, equus burchelli antiquorum, buffalo, syncerus caffer, hippopotamus, hippopotamus amphibius, and impala, aepyceros melampus. infestation rates in the herbivores vary from 60% in zebra to less than 1% in impala. species like elephant, loxodonta africana, and blue wildebeest, connochaetes taurinus, do not ... | 1975 | 1219111 |
| nematode parasites from burchell's zebras in south africa. | twenty-five burchell's zebras (equus burchelli antiquorum) which were culled at monthly intervals in the kruger national park were examined for helminths. twenty-nine species of nematodes belonging to the families atractidae, habronematidae, onchocercidae, oxyuridae, strongylidae, strongyloididae and trichostrongylidae were recovered. the cyathostomes (small strongyles) most abundant were cyathostomum tetracanthum, cylicostephanus calicatus, cylindropharynx sp. (? c. intermedia theiler, 1923) an ... | 1987 | 3625897 |
| ultrastructure of filamentous microorganisms associated with zebra cyathostomes. | filamentous microorganisms were observed colonizing the cuticle of cyathostomes (nematoda: strongylidae) collected from the large intestine of burchell's zebra (equus burchelli antiquorum). scanning (sem) and transmission (tem) electron microscopy revealed three filamentous microorganisms, designated as segmented, continuous multicellular, and helical. the segmented and continuous multicellular morphotypes each revealed a process of segmentation in their developmental stages, and those of the se ... | 1990 | 24196311 |
| a comparative study of gastrointestinal parasites between ranched and free ranging burchell's zebra (equus burchelli antiquorum) in isiolo district, kenya. | parasites were collected from 20 burchell's zebra, equus burchelli antiquorum, from isiolo district, kenya. 10 were ranched animals from the lewa downs ranch and 10 free ranging from the areas adjacent to the ranch to the north. the animals were culled from 4th to 18th june 1995. the gastrointestinal tract was removed from the carcass and separated as stomach, small and large intestines and searched for parasites. the abdominal cavity was scrutinized for setaria species. the parasites were ident ... | 2004 | 15365235 |
| hydatidosis in a chapman's zebra (equus burchelli antiquorum). | a 14-year-old male chapman's zebra had been treated for a cervical granulomatous cellulitis for 3 months prior to sudden death associated with myocardial fibrosis. incidental findings at necropsy included multiple 3-8-cm unilocular cysts in the liver and lungs. cysts contained either a clear fluid with or without hydatid sand or a gelatinous substance with foci of mineralization. light and scanning electron microscopic examination of the hydatid sand revealed free protoscolices as well as intact ... | 2001 | 11724148 |
