| systemic infection with an unidentified toxoplasma-like protozoan in a neonatal lichtenstein's hartebeest (sigmoceros lichtensteinii). | an unidentified toxoplasma gondii-like disseminated infection was found in tissues of a 2-day-old hartebeest. protozoal tachyzoites were about 3.5 x 1.7 microns, had electron-dense rhoptries, and divided by endodyogeny. the organism did not stain with polyclonol antibodies to t. gondii, neospora caninum, or sarcocystis cruzi. | 1996 | 8636866 |
| cytochrome b phylogeny of the family bovidae: resolution within the alcelaphini, antilopini, neotragini, and tragelaphini. | the family bovidae is characterized by an incomplete fossil record for the period during which most bovid subfamilies emerged. this, coupled to extensive morphological convergence among species, has given rise to inconsistencies in taxonomic treatments, especially at the tribal and subfamilial levels. in an attempt to clarify some of these issues we analyzed the complete mtdna cytochrome b gene (1140 bp) from 38 species/subspecies representing at least nine tribes and six subfamilies. specific e ... | 1999 | 10222159 |
| anesthesia of boma-captured lichtenstein's hartebeest (sigmoceros lichtensteinii) with a combination of thiafentanil, medetomidine, and ketamine. | a dose range was determined for anesthesia of recently boma-captured lichtenstein's hartebeest (sigmoceros lichtensteinii) (n = 13) with the synthetic opiate thiafentanil (thia) (formerly called a3080) combined with medetomidine (med) and ketamine (ket) in the kasungu national park, malawi on 4 to 5 september 1999. the dose range of 11-29 micrograms/kg thia (mean +/- sd = 21 +/- 4 micrograms/kg) combined with 5-10 mg/kg med (8 +/- 1 micrograms/kg) plus 0.7-1.4 mg/kg ket (1.1 +/- 0.2 mg/kg) was f ... | 2002 | 12038149 |
| prevalence of nasal bots (diptera: oestridae) in some zambian hartebeest. | nine lichtenstein's hartebeest ( alcelaphus lichtensteini ) were sampled for nasal bots ( oestrinae ) in a woodland area of central western zambia. larvae of the genera gedoelstia , oestrus and kirkioestrus were found in mixed infestations in the nasal cavities and paranasal sinuses. a maximum count of 252 larvae was recorded from one head but no obvious pathogenicity was detectable in this or any other hartebeest. the significance of these findings is discussed in relation to the host specifici ... | 1977 | 24228960 |
