Trichomonas gallinae in wild raptors on the Cape Peninsula : short communication

An outbreak of avian trichomoniasis caused by Trichomonas gallinae occurred on the Cape Peninsula and surrounds in seven species of diurnal and nocturnal birds of prey. The virulence of the parasite appears to be different from that reported in the northern hemisphere. It is suggested that this disease might negatively affect the reproductive success of certain species. A survey of the epidemiology of Trichomonas gallinae in the families Columbidae, Falconidae and Strigidae will illuminate its potential to affect the viability of future populations. 'n Uitbraak van trichomoniase veroorsaak deur Trichomonas gallinae het in die Kaapse Skiereiland en omliggende gebiede voorgekom, en sewe spesies van dag- en naglewende roofvoels is aangetas. Die virulensie van die parasiet blykbaar anders as die wat in die noordelike halfrond gerapporteer is. Daar word voorgestel dat hierdie siekte voortplantingsukses van sekere spesies negatief mag beinvloed. 'n Opname van die epidemiologie van Trichomonas gallinae in die families Columbidae, Falconidae en Strigidae sal lig werp op die parasiet se potensiaal om die lewensvatbaarheid van toekomstige populasies te beinvloed.
