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

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.

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

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

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.

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) type 2 is the causative agent of acute hemorrhagic enteritis and high mortality in the affected dogs. Numerous studies have been done to understand the origin of the virus and to exhibit new variants and circulating strains. This report describes the detection and genomic characterization of CPV strains from indoor and outdoor dogs in Ankara, Turkey. Samples were sent to our laboratory due to clinical symptoms in puppies. We tested blood and swab samples to determine the presence of canine parvovirus (CPV) in three puppies and two adult dogs by reverse transcription-pol

ZusammenfassungDie Impfung ist die wichtigste Maßnahme zum Schutz vor kaniner Parvovirose. Daher zählt die Impfung gegen das kanine Parvovirus (CPV) zu den Core-Komponenten der Hundeimpfung. Modifizierte Lebendvakzinen (MLV) haben sich als sehr wirksam und zugleich sicher erwiesen. Sie bieten einen zuverlässigen Schutz, der bereits nach wenigen Tagen eintritt und viele Jahre anhält. MLV enthalten keine Adjuvanzien; sie sind hinsichtlich ihres allergenen und toxischen Potenzials Impfstoffen mit inaktiviertem CPV in aller Regel überlegen. Aus diesen Gründen werden MLV Impfstoffen aus inaktiviert

Résumé :

Canine parvovirus (CPV) is a highly contagious viral pathogen affecting dogs aged 6-21 weeks primarily targeting rapidly dividing cells of GI tract, which leads to haemorrhagic gastroenteritis and symptoms such as fever, vomiting, in appetence and abdominal pain. Several variants include CPV-2, CPV-2b and CPV-2c. CPV can be prevented by timely and complete vaccination and can be treated effectively if timely diagnosis is done. It can be diagnosed by effective methods such as PCR, fecal ELISA, HA and HI, the most effective being ELISA and PCR. Therefore, the present research was aimed at develo

Résumé :

Canine parvovirus (CPV-2) is one of the most important pathogens in dogs, and despite the continual development of vaccines against CPV-2, CPV-2 is still circulating in the canine population. The CPV-2a/2b/2c variant has replaced the original CPV-2 virus and seems to exhibit accelerated transmission. Although CPV-2 infection has been frequently reported, no studies have summarized information of CPV-2 variants currently circulating worldwide. To track the evolution of CPV-2, we downloaded and analyzed all VP2 sequences from the NCBI database (from 1978 to 2022). We found that CPV-2c shows a te

Canine parvovirus type 2 (CPV-2) is a highly contagious virus that causes acute gastroenteritis in dogs all over the world. Because of its stability in the environment, CPV-2 can remain infective for a long time, especially if protected in organic matter. To demonstrate CPV-2’s potential as an environmental hazard for nonimmunized susceptible hosts, we investigated 50 faecal samples collected from public areas in a municipality of Paraná state, Brazil. Seven samples tested positive for CPV by a PCR assay targeting the partial VP2 gene, with three strains being confirmed as CPV-2b variant and o

Résumé :

Abstract Canine parvovirus type-2 (CPV-2) is a DNA virus that causes a very common worldwide diffused infectious disease in dogs. Since its appearance, the CPV-2 evolved generating novel genetic and antigenic variants (CPV-2a/2b/2c) which are distributed throughout the world. In the present study, the frequency of CPV-2 in a canine population in Sicily (Italy) was investigated, using a polymerase chain reaction (PCR) for a fragment of the VP2 gene. Out of a total of 673 samples from 370 dogs, submitted to the laboratory from July 2009 to August 2015, 265 samples (39.38%) were positive and thes

Canine Parvovirus (CPV) is a highly infectious viral illness that primarily affects dogs, especially puppies aged between six weeks and six months. It is caused by Canine Parvovirus type 2 (CPV-2), which mainly targets the gastrointestinal system and, in some instances, the heart. The virus attacks rapidly dividing cells such as those in the intestinal crypts, bone marrow, and lymphoid tissues, resulting in enteritis, leukopenia, and immunosuppression. Since its discovery, CPV-2 has evolved into multiple strains, contributing to its high virulence. This article focuses on the predominant CPV-2

Canine parvovirus (CPV) is a significant pathogenic virus with up to 100% morbidity and 91% mortality rates, especially in unvaccinated puppies.

Therefore, to cope with CPV disease, it is important to identify the viral agent and regularly monitor vaccine effectiveness against new strains.
