Cross sectional and longitudinal surveys of canine enteric coronavirus infection in kennelled dogs: A molecular marker for biosecurity

► Canine coronavirus prevalence in 4 kennels and shelters varied from 5.3% to 33.3%. ► Transmission pathways were demonstrated by quantitative PCR and sequencing. ► A small number of persistently shedding dogs may contribute to maintenance of infection. ► CECoV may be a marker for hygiene and biosecurity.
