“…CPV-2b was the predominant genotype, which is in agreement with the subtype found in the United Kingdom and in some European countries (Decaro & Buonavoglia 2012). This is also in agreement with Pereira et al (2000) and Castro et al (2011), who reported a predominance of CPV-2a in the years 1980 and 1995-2006, a situation that changed for fecal samples collected from 1990-1995 and 2007-2009, in which CPV-2b was the predominant subtype. In our study, only one dog was infected with the genotype CPV-2a and another one with CPV-2c.…”

“…Evaluating 32 positive hemagglutination (HA)/hemagglutination inhibition (HI) and PCR fecal samples from unvaccinated puppies, Castro et al (2010) (Castro et al 2011), while evaluating canine parvovirus from 37 infected and previously vaccinated puppies in the period 1995-2009, found only CPV-2a and CPV-2b, with CPV-2c being absent. The authors concluded that there was no interference in the ability of commercial vaccines to protect puppies against circulating canine parvovirus, but they did suggest the need to continue monitoring for new variants.…”

Since the first isolation of canine parvovirus type 2 (CPV-2) in late 70's new virus types as CPV-2a and CPV-2b have been emerged and becoming prevalent in natural canine population and more recently, a third subtype was identified , CPV-2c. The main purpose of this study was to detect and characterize canine parvovirus currently present in Central--West region of São Paulo state, in Brazil. Fecal samples were collected of vaccinated and non-vaccinated dogs, clinically suspected of having CPV infection brought to the Infectious Diseases Service, Veterinary Hospital of FMVZ-UNESP. All samples (n=30) were screening for canine parvovirus through hemagglutination test and those resulting as positive (n=20) were submitted to PCR and the products were subsequently sequenced for subtype characterization. Results were tested for association with age, hematological values, viral hemagglutination titers in the feces, vaccination status and survival. Leukopenia was found in all animals, death occurred in 30% of unvaccinated dogs and in 42% of vaccinated ones. In a total of 20 positive sequenced samples, 18 were classified as CPV-2b, one as CPV-2c, and one as CPV-2a, being CPV2a and CPV2c detected in unvaccinated puppies. Compared to the reference samples amino acid change at position 426 in those circling virus was identified. The study results demonstrate the predominance of CPV-2b and the presence of CPV-2a and CPV-2c in naturally infected, vaccinated and unvaccinated dogs in in São Paulo region.INDEX TERMS: Canine parvovirus, PCR, viral type, dogs.

“…From 1980 to the present, CPV-2a and 2b have been the most significant CPV variants circulating in the Southeast region of Brazil (Pereira et al 2007, Castro et al 2011). However, CPV-2c has been detected in epidemiological surveys conducted in South America (Pérez et al 2007) including Southern (Streck et al 2009) and Southeast region of Brazil (Castro et al 2010).…”
