title: Prevalence of intestinal parasites in breeding cattery cats in Japan.
abstract: To address the lack of up-to-date published data, the present study assessed the prevalence of intestinal parasites in breeding catteries in Japan.
  
  
  
  Fresh faecal samples were randomly collected from 342 cats (aged 1 month to 12 years) in seven breeding catteries in Japan, located in prefectures of Nagano (n = 2), Saitama (n = 1), Aichi (n = 2), Gifu (n = 1) and Miyagi (n = 1), on a single occasion. The samples were tested for the presence of Giardia species copro-antigen using a commercially available enzyme-linked immunosorbent assay kit. Other intestinal parasites were identified microscopically using the formalin-ethyl acetate sedimentation technique.
  
  
  
  The total prevalence of intestinal parasites was 20.8%; only two genera of protozoa (Giardia species: 18.7% and Cystoisospora species: 5.0%) were detected. Coinfections of both protozoans were recorded in 2.9% of cats. In contrast, no helminths were detected. The presence of total infection, Giardia species, Cystoisospora species and multiple infections in cats <1 year old were significantly more prevalent than in cats ⩾1 year old. There were no significant differences among faecal conditions with or without intestinal parasites. Giardia species infection was present in samples from all breeding catteries, except for one facility. Cystoisospora species and coinfections were shown in four and two breeding catteries, respectively. The prevalence of intestinal parasites was markedly variable among the breeding catteries.
  
  
  
  The present study demonstrates the significance of Giardia species and Cystoisospora species infections in breeding cattery cats. Additionally, it is suggested that environmental contamination is the most important factor influencing the prevalence of protozoal infections in breeding catteries.
