14) Immunology
I am not aware of any studies.
15) Pathological features
Malignant catarrhal fever has been reported to occur in a roan antelope at Regent's Park by Gulland et al. (1989).Reid & Bridgen (1991) recovered a herpes virus from cryopreserved roan antelope cells and established its closer relationship to the alcelaphine herpesvirus than the ovine virus (OHV-2). When injected into rabbits it produced malignant catarrh and the authors concluded that the roan antelope needs to be considered a potential carrier of this virus. Similarly, Flach et al. (2002) isolated the virus from roan and other captive artiodactyl species. Kariuki et al. (1989) identified Amblyomma and liver flukes at Ruma National Park. The only pathological diagnosis made by Griner (1983) in his extensive experience with zoo animal pathology is a case of aspiration pneumonia whose ultimate cause could not be determined. Other data on blood parasites may be found in Wilson & Hirst (1977).
16) Physiologic data
Hematological studies to establish basic values were published by Pospisil et al. (1984). Hattingh (1988) studied the biochemical responses to stress in roan and impala. Citino et al. (2001) made extensive observations on the effects of anesthetic agents in roan antelopes and prescribed a recommended dose for immobilization. The gastric anatomy of eleven different Zambian game animals, including the roan antelope, was described by Stafford & Stafford (1993).
17) Other resources
Fibroblast cell strains of several roan antelopes are available from CRES at the San Diego Zoo and can be obtained by contacting Dr. Oliver Ryder at oryder@ucsd.edu.
18) Other remarks - What additional Information is needed?
No early embryological studies or early stages of implantation have been described. Endocrine studies of gestations are needed.
