Résumé :

In this study, a virulent field canine parvovirus type - 2a variant (CPV-new 2a) strain, ABT/CPV/MVC02, was identified from the faeces of a Dog with severe haemorrhagic gastroenteritis in Chennai, Tamil Nadu, India. The genomic sequence of ABT/CPV/MVC02 (MN661243) shares 99.33% nucleotide identity with those of CPV new 2a variant strains. Based on the VP2 capsid protein amino acid variation (Ser297Ala), the ABT/CPV/MVC02 strain is classified as a new CPV 2a variant strain. Two VP2 mutations Tyr324Ile and Thr440Ala were reported in most of the CPV-2a stains also present in ABT/CPV/MVC02.The phy

Résumé :

Canine parvovirus (CPV-2) is the causative agent of haemorrhagic gastroenteritis in canids. Three antigenic variants—CPV-2a, CPV-2b and CPV-2c—have been described, which are determined by variations at residue 426 of the VP2 capsid protein. In Colombia, the CPV-2a and CPV-2b antigenic variants have previously been reported through partial VP2 sequencing. Mutations at residues Asn428Asp and Ala514Ser of variant CPV-2a were detected, implying the appearance of a possible new CPV-2a variant in Colombia. The purpose of the present study was to characterise the full VP2 capsid protein in samples fr

Background and Aim: According to the previous study, the circulating canine parvovirus (CPV) in Thailand is 2a and 2b. Nowadays, CPV mutants, including CPV-2c, have been identified in many parts of the world. This study aimed to investigate the genetic diversity of the circulating CPV in Thailand. Materials and Methods: Eighty-five CPV-positive fecal samples were obtained from dogs with either acute hemorrhagic diarrhea or diarrhea. The complete VP2 gene of these samples was amplified using VP2 specific primers and polymerase chain reaction (PCR). The obtained full-length VP2 sequences were an

Résumé :

ABSTRACT The antigenic relationships among the original canine parvovirus type 2 (CPV-2) and the variants CPV-2a, -2b, and -2c were evaluated. Cross-antigenic evaluation revealed clear differences among the CPV variants, which were more appreciable by serum neutralization (SN) than by hemagglutination inhibition. Antigenic differences were found mostly between the original CPV-2 and the variants, but they were also observed among the variants CPV-2a, -2b, and -2c. The variant CPV-2c exhibited a unique antigenic pattern, since it was poorly recognized by the sera of animals immunized with CPV-2

Résumé :

Canine parvovirus (CPV) is a highly contagious and lethal virus that causes severe gastroenteritis and myocarditis in young dogs. In 1978, CPV has rapidly spread worldwide, resulting in outbreaks and high morbidity rates among dog populations. Over a decade, CPV has undergone genetic changes, leading to the emergence of different genotypes (CPV-2a, CPV-2b, and CPV-2c), which have expanded its host range to include cats and tissue culture cells. This review focuses on CPV-2 outbreaks in India from 2010 to 2023, analyzing gene lengths covering 274-438 amino acids in the VP2 gene which are collec

Résumé :

The first detection of canine parvovirus type-2 (CPV-2) was in the early 1970s, when it was known to cause severe gastroenteritis in dogs. However, it has evolved over the years into CPV-2a within 2 years, into CPV-2b after 14 years, into CPV-2c after 16 years and more recently CPV-2a-, 2b- and 2c-like variants reported in 2019, with a global distribution. Reports on the molecular epidemiology of this virus are missing in most African countries. The report of clinical cases among vaccinated dogs in Libreville in Gabon triggered the execution of this study. The objective of this study was to ch

O Parvovírus Canino (CPV) é um patógeno emergente em cães, isolado pela primeira vez em 1978, nos Estados Unidos. A amostra original de 1978 foi designada CPV tipo 2 (CPV-2). Entretanto, análises de isolados de CPV dos Estados Unidos, por enzimas de restrição e anticorpos monoclonais demonstraram que cerca de 1979, uma amostra variante, designada CPV tipo 2a (CPV-2a) tornou-se prevalente. Subseqüentemente, uma nova amostra antigênica, designada CPV tipo 2b (CPV-2b) também foi observada por análises de isolados de CPV de várias partes do mundo, embora a proporção fosse diferente entre os países

Résumé :

To date, there is a dearth of information on canine parvovirus-2 (CPV-2) from the Caribbean region. During August–October 2020, the veterinary clinic on the Caribbean island of Nevis reported 64 household dogs with CPV-2-like clinical signs (hemorrhagic/non-hemorrhagic diarrhea and vomiting), of which 27 animals died. Rectal swabs/fecal samples were obtained from 43 dogs. A total of 39 of the 43 dogs tested positive for CPV-2 antigen and/or DNA, while 4 samples, negative for CPV-2 antigen, were not available for PCR. Among the 21 untested dogs, 15 had CPV-2 positive littermates. Analysis of th

Résumé :

ABSTRACT Canine parvovirus (CPV) is classified as a member of the feline parvovirus (FPV) subgroup. CPV isolates are divided into three antigenic types: CPV type 2 (CPV-2), CPV-2a, and CPV-2b. Recently, new antigenic types of CPV were isolated from Vietnamese leopard cats and designated CPV-2c(a) or CPV-2c(b). CPV-2c viruses were distinguished from the other antigenic types of the FPV subgroup by the absence of reactivity with several monoclonal antibodies (MAbs). To characterize the antigenicity of CPV-2c, a panel of MAbs against CPV-2c was generated and epitopes recognized by these MAbs were

The aim of this work is to detect canine parvovirus 2 (CPV-2) by standard polymerase chain reaction (PCR). Viral DNA was isolated from faecel samples of 36 puppies with suspicious symptoms for parvovirus infection and used as template in standard PCR. 23 samples wereof CPV-2b serotype, 9 samples of CPV-2a serotype but 4 samples were neither 2b and nor 2a. We used two different primer sets, one specific both serotypes CPV-2a and CPV-2b and one specific only for CPV-2b. T

Canine parvovirus-2 (CPV-2) is a highly contagious and key enteropathogen affecting the canine population around the globe by causing canine parvoviral enteritis (CPVE) and vomition. CPVE is one of the the leading causes of morbidity and mortality in puppies and young dogs. Over the years, five distinct antigenic variants of CPV-2, namely CPV-2a, CPV-2b, new CPV-2a, new CPV-2b, and CPV-2c, have emerged throughout the world. CPV-2 infects a diverse range of wild animals, and the newer variants of CPV-2 have expanded their host range to include felines. Despite the availability of highly specifi
