title: Identity of Sarcocystis species of the water buffalo (Bubalus bubalis) and cattle (Bos taurus) and the suppression of Sarcocystis sinensis as a nomen nudum.
abstract: There are uncertainties concerning the identity and host species specificity of Sarcocystis species of the water buffalo (Bubalus bubalis) and cattle (Bos taurus). Currently, in cattle three species are recognized with known endogenous stages, viz.: S. cruzi (with canine definitive host), S. hirsuta (feline definitive host), and S. hominis (primate definitive host). Recently, a fourth Sarcocystis species with an unknown life cycle has been reported from cattle. In the water buffalo, four species of Sarcocystis have been described: S. fusiformis (feline definitive host), S. buffalonis (feline definitive host), S. levinei (canine definitive host), and S. dubeyi (definitive host unknown but not cat or dog). Besides, there are studies of Sarcocystis infections in buffalo and cattle from China with results that are difficult to interpret and validate. For example, some of the studies report transmission of Sarcocystis species between cattle and buffalo, but steps to preclude exogenous exposures were not reported. A species of the water buffalo, 'S. sinensis', was proposed at a Chinese national conference in 1990, and published as an abstract without figures and with no archived type specimens for verification. The International Code of Zoological Nomenclature Articles 9 and 10 state that "abstracts of articles, papers, posters, text of lectures, and similar material when issued primarily to participants at meetings, symposia, colloquia or congress does not constitute published work"; therefore, S. sinensis is a nomen nudum.
