Canine circovirus (CanineCV) has been detected in some dogs with severe haemorrhagic diarrhoea, but its pathogenic role is unclear. This study evaluated a suspected association between the presence of CanineCV and acute haemorrhagic diarrhoea syndrome (AHDS) in dogs. The prevalence of CanineCV in dogs with AHDS was compared with that in healthy dogs and those infected with canine parvovirus (CPV). Additionally, time to recovery and mortality rate were compared between CanineCV-positive and CanineCV-negative dogs. Faecal samples of dogs with AHDS (n=55), healthy dogs (n=66) and dogs infected with CPV (n=54) were examined by two real-time TaqMan PCR assays targeting the replicase and capsid genes of CanineCV. CanineCV was detected in faecal samples of two dogs with AHDS, three healthy controls and seven dogs infected with CPV. Among the three groups, there was no significant difference in prevalence of CanineCV. CPV-infected animals that were coinfected with CanineCV had a significantly higher mortality rate compared with those negative for CanineCV. CanineCV does not appear to be the primary causative agent of AHDS in dogs, but might play a role as a negative co-factor in disease outcome in dogs with CPV infection.

Modern pig farming is characterised by the emergence of several syndromes whose aetiology is unclear or has a multifactorial origin, including periweaning failure-to-thrive syndrome (PFTS). In fact, its specific aetiology remains elusive, although several causes have been investigated over time. The present study aimed to investigate the potential role of viral agents in PFTS-affected and healthy animals by evaluating the virome composition of different organs using a metagenomic approach. This analysis allowed demonstrating a higher abundance of Porcine parvovirus 6 (PPV6) in healthy subjects while Ungulate bocaparvovirus 2 (BoPV2), Ungulate protoparvovirus 1 (PPV) and Porcine circovirus 3 (PCV-3) were increased in pigs with PFTS. No differential abundance of RNA viruses was found between PFTS-affected and control pigs. Remarkably, this is the first molecular characterisation of PPV6 and BoPV2 in Spain and one of the few all around the world, supporting their apparent widespread circulation. Interestingly, PCV-3 has been recently identified in several clinical-pathological conditions as well as in healthy pigs, while BoPV2 pathogenic potential is unknown. Although obtained results must be taken as preliminary, they open the door for further studies on the potential role of these viruses or their combination as predisposing factor/s for PFTS occurrence.

Positive canine parvovirus (CPV) faecal test results have been reported in dogs after modified live virus (MLV) vaccination. Thus, the aim was to investigate feline panleucopenia virus (FPV) shedding in recently vaccinated, adult, clinically healthy cats and to assess related factors. Forty cats were vaccinated with an FPV MLV vaccine. Faeces of cats were tested for presence of parvovirus DNA on days 7, 14, 21 and 28 by quantitative real-time PCR; DNA-positive samples were subjected to partial VP2 gene sequencing. Virus isolation was performed whenever sufficient amounts of faeces were available. Serum antibody titres were measured by haemagglutination inhibition on days 0, 7 and 28. Overall, 30.0 per cent (12/40; 95% CI 18.0 to 45.6) of cats shed parvovirus DNA. Sequencing revealed FPV vaccine virus DNA in three cats, FPV field virus DNA in four cats and CPV field virus DNA in one cat. Shedding was significantly associated with lack of prevaccination antibody titres (40) (P=0.016; OR: 6.44; 95% CI 1.44 to 28.89) and with postvaccination titre increases (fourfold) (P=0.029; OR: 5.00; 95% CI 1.17 to 21.39). Shedding of field or vaccine virus DNA seems to be common in healthy cats which can be a concern in shelters and catteries. Diagnostic tools should be developed to facilitate differentiation of vaccine and field virus shedding.
