title: Hammondia heydorni oocysts in the faeces of a greyhound in New Zealand.
abstract: OBJECTIVE
  To identify oocysts found in faecal material of a greyhound.
  
  
  METHODS
  Polymerase chain reaction (PCR) and DNA sequencing were used to study genomic DNA isolated from oocysts purified from faeces of a greyhound.
  
  
  RESULTS
  Database searches with the DNA sequences obtained showed they were derived from Hammondia heydorni. A species-specific PCR was developed to detect H. heydorni DNA.
  
  
  CONCLUSIONS
  Light microscopy in conjunction with PCR and DNA sequencing definitively identified the presence of H. heydorni oocysts in faeces of a greyhound.
  
  
  CONCLUSIONS
  This study confirms the presence of H. heydorni in New Zealand and indicates the need to correctly identify similar oocysts from dogs, rather than assume they are Neospora caninum.
