Genotypic and phenotypic diversity of trypanosomes infecting Australian marsupials and their association with the population decline of the brush-tailed bettong or woylie (Bettongia penicillata)

TL;DRAbstract

Trypanosomes are flagellated blood parasites that are capable of infecting virtually all classes of vertebrates. They range from non-pathogenic species to those that are highly pathogenic and are the causative agents of many diseases of medical and veterinary importance. While much is known of their impact on human health or economic development, a great deal less is known of those associated with wildlife. Within Australia, trypanosomes have been found naturally infecting a wide range of native marsupials, most of which are considered threatened or endangered. However, their research has largely been confined to the description of trypanosome morphology in blood, and a complete lack of information regarding their life cycle, virulence, and pathogenicity is evident. This study therefore, aimed to investigate the genotypic and phenotypic diversity of Trypanosoma spp. infecting Western Australia marsupials and to determine their potential pathogenicity with particular emphasis in the
