Neospora caninum infection in birds: experimental infections in chicken and embryonated eggs.

abstract：:Population genetics of multi-host pathogens offers great potential for the understanding of their complex epidemiology but care must be taken to ensure that the sampling procedure does not bias estimates of population indices. The transfer of material to laboratory passage, in particular, runs the risk of bottleneckin...
