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

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 :

Canine Parvovirus-2 (CPV-2) is a highly lethal virus that affects the canid family. It targets rapidly dividing cells in organs such as the intestines, thymus, lymph nodes, bone marrow, and heart, often resulting in multi-organ failure.This study aimed to evaluate the impact of CPV-2 variants on clinico-physiological, haematological and biochemical parameters in dogs. Two hundred faecal and blood samples from symptomatic dogs, along with 10 healthy controls, were collected at VCC, PGIVER, Jaipur, from July 2024 to December 2024. PCR identified 166 CPV-2 positive cases, comprising 147 CPV-2a, 1

Résumé :

Canine parvovirus (CPV) is a major pathogen in canines, with a high mortality rate in unvaccinated puppies. CPV is traditionally classified into three antigenic variants (CPV-2a, CPV-2b and CPV-2c) based on the amino acid sequence of the VP2 protein. Currently, various mutations are described in the receptor-binding area or in the regions of greatest antigenicity of the VP2 protein, giving rise to new viral variants that are capable of immunological escape, affecting the protective immunity of traditional vaccines. In the present study, a molecular characterization of the VP2 gene was performe

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

Résumé :

Canine parvovirus type 2 (CPV-2) is an infectious agent relevant to domestic and wild carnivorans. Recent studies documented the introduction and spread of CPV-2c strains of Asian origin in the Italian canine population. We investigated tissue samples from a puppy collected during necropsy for the presence of viral enteropathogens and all samples tested positive only for CPV-2. The full coding sequence of a CPV-2b (VP2 426Asp) strain was obtained. This virus was related to CPV-2c strains of Asian origin and unrelated to European CPV-2b strains. The sequence had genetic signatures typical of As

Résumé :

Canine parvovirus is a highly contagious virus that causes fatal disease acute hemorrhagic enteritis and myocarditis in dogs. 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

Résumé :

The canine parvovirus (CPV) is prevalent in India but only scanty literature is available on molecular differentiation of its strain using polymerase chain reaction. In the present study, 100 faecal samples from dogs suspected for canine parvo virus infection (gastroenteritis) were collected and processed for isolation of viral genomic DNA. Molecular test like PCR assay using 3 specific pairs of primers (pCPV-RT, pCPV-2ab and pCPV- 2b) was conducted for differential diagnosis of the virus type. Out of 100 faecal samples, 63 were positive for presence of CPV, of which 54 were CPV-2b and 9 were

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 :

Canine parvovirus (CPV) is a significant pathogen that affects wild and domestic dogs globally, resulting in intricate pathological and epidemiological consequences, primarily observed in puppies, such as haemorrhagic enteritis and myocarditis. This virus is categorized into three strains: CPV-2a (which replaced the original strain CPV-2), CPV-2b, and CPV-2c. The objective of this study was to determine the status of CPV-2 and its circulating variants in domestic dogs residing in the Morogoro and Arusha regions of Tanzania.

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
