BACKGROUND: Infection with Parvovirus B19 (B19V), Cytomegalovirus (CMV) and Herpes Simplex Virus-1/2 (HSV-1/2) may cause fetal loses including spontaneous abortion, intrauterine fetal death and non-immune hydrops fetalis. Few comprehensive studies have investigated first-trimester spontaneous abortions caused by virus infections in Chongqing, China. Our study intends to investigate the infection of B19V, CMV and HSV-1/2 in first-trimester spontaneous abortions and the corresponding immune response...

The aim of this study was to establish a multiplex PCR (mPCR) method that can simultaneously detect canine parvovirus (CPV-2), canine coronavirus (CCoV) and canine adenovirus (CAV), thereby eliminating the need to detect these pathogens individually. Based on conserved regions in the genomes of these three viruses, the VP2 gene of CPV-2, the endoribonuclease nsp15 gene of CCoV, and the 52K gene of CAV were selected for primer design. The specificity of the mPCR results showed no amplification of canine distemper virus (CDV), canine parainfluenza virus (CPIV), or pseudorabies virus (PRV), indicating that the method had good specificity...

Objectives: Haemolytic disease of the fetus and newborn (HDFN) causes hydrops fetalis . The successful treatment of HDFN has been reported with intrauterine blood transfusion (IUT). This study aimed to describe the initial experience with IUT procedures in Oman. Methods: This retrospective observational study took place at the Royal Hospital and Sultan Qaboos University Hospital Blood Bank, Muscat, Oman, and included all women who underwent IUT procedures in Oman between March 2012 and March 2016...

BACKGROUND: Previous data suggest that fecal S100A12 has clinical utility as a biomarker of chronic gastrointestinal inflammation (idiopathic inflammatory bowel disease) in both people and dogs, but the effect of gastrointestinal pathogens on fecal S100A12 concentrations is largely unknown. The role of S100A12 in parasite and viral infections is also difficult to study in traditional animal models due to the lack of S100A12 expression in rodents. Thus, the aim of this study was to evaluate fecal S100A12 concentrations in a cohort of puppies with intestinal parasites (Cystoisospora spp...

Human parvovirus B19 (B19) infection is common among blood donors, and healthy blood donors can transmit virus via transfusion. Due to resistance of B19 to viral inactivation methods, there is a potential concern regarding transfusion safety in blood products. We aimed to determine the seroprevalence, molecular epidemiology and quantitation of B19 DNA levels in blood donors in Tehran, Iran. 500 blood donors from Blood Transfusion Research Center were studied. ELISA was used for detection of B19 IgG and IgM and nested PCR was carried out for detection of B19 DNA...

Shrimp hemocyte iridescent virus (SHIV) is a recently reported shrimp virus, which threats the cultured white-leg shrimp Litopenaeus vannamei and can cause huge economic loss in shrimp farming industry in China. A quantitative real time polymerase chain reactio (qPCR) assay was developed using a TaqMan probe to detect and quantify SHIV. A pair of qPCR primers, which amplify a 188 bp DNA fragment, and a TaqMan probe were selected from ATPase gene (ORF114R) of the SHIV genome. The primers and TaqMan probe used in this assay were shown to be specific for SHIV and did not react with White spot syndrome virus (WSSV), Infectious hypodermal and hematopoietic necrosis virus (IHHNV), Hepatopancreatic parvovirus (HPV), Vibrio parahaemolyticus causing acute hepatopancreatic necrosis disease (VPAHPND ), and Enterocytozoon hepatopenaei (EHP), or healthy shrimp DNA...

Canine parvovirus (CPV) is a fast-evolving single-stranded DNA virus that causes one of the most significant infectious diseases of dogs. Although the virus dispersed over long distances in the past, current populations are considered to be spatially confined and with only a few instances of migration between specific localities. It is unclear whether these dynamics occur in South America where global studies have not been performed. The aim of this study is to analyze the patterns of genetic variability in South American CPV populations and explore their evolutionary relationships with global strains...

OBJECTIVE: To investigate the association between human parvovirus B19 (B19V) infection in the thymus and myasthenia gravis (MG). METHODS: The presence of human B19V DNA and protein was assessed in 138 samples, including 68 thymic hyperplasia (39 with MG), 58 thymoma (23 with MG), and 12 normal thymus tissues, by nested polymerase chain reaction, immunohistochemistry, laser capture microdissection, and sequencing in a double-blinded manner. RESULTS: B19V DNA was mainly detected in thymic hyperplasia, and the positive rate (41...

Most human emerging infectious diseases originate from wildlife and bats are a major reservoir of viruses, a few of which have been highly pathogenic to humans. In some regions of Cameroon, bats are hunted and eaten as a delicacy. This close proximity between human and bats provides ample opportunity for zoonotic events. To elucidate the viral diversity of Cameroonian fruit bats, we collected and metagenomically screened eighty-seven fecal samples of Eidolon helvum and Epomophorus gambianus fruit bats. The results showed a plethora of known and novel viruses...

goose parvovirus (GPV) belongs to the Dependoparvovirus genus in Parvovirinae subfamily within Parvoviridae family, is the etiological agent of Derzsy's disease. Nuclear localization signal (NLS) is important for parvovirus lifecycle in the delivery of genomes and the structural protein of progeny virus into the nucleus. Here, NLS was first identified in GPV. By using the PSORT II program, a basic region (BR, 160YPVVKKPKLTEE171) in the N-terminus of VP1 was found, which predicted as putative NLS motif of goose parvovirus capsid...

Acute hemorrhagic diarrhea syndrome (AHDS), formerly named canine hemorrhagic gastroenteritis, is one of the most common causes of acute hemorrhagic diarrhea in dogs, and is characterized by acute onset of diarrhea, vomiting, and hemoconcentration. To date, histologic examinations have been limited to postmortem specimens of only a few dogs with AHDS. Thus, the aim of our study was to describe in detail the distribution, character, and grade of microscopic lesions, and to investigate the etiology of AHDS. Our study comprised 10 dogs with AHDS and 9 control dogs of various breeds, age, and sex...

Canine parvovirus (CPV) can cause severe disease in animals, especially in dogs, and continuously generates new variants. In this study, the complete VP2 genes of 59 CPV isolates from clinical diseased dogs between 2015 and 2016 in 4 Chinese provinces were sequenced and analyzed. The results showed that new CPV-2a was still the prominent CPV genotype, followed by CPV-2c and new CPV-2b. CPV-2c with Ala5Gly and Gln370Arg mutations was first detected in Henan, Guangxi and Jiangsu provinces in China. A phylogenetic tree based on VP2 sequences showed that all isolates in this study formed a close lineage which separated from foreign isolates...

Canine parvovirus type 2 (CPV-2) has been reported worldwide as the main agent related to acute hemorrhagic enteritis of high morbidity and variable mortality in puppies. The detection and characterization of this virus is essential to understand the etiology of the disease and to develop control measures. To characterize the virus circulating in Peruvian dogs and to provide new insights into the local diversity of CPV-2, rectal swabs from 39 puppies with clinical symptoms and with no history of previous vaccinations were analyzed...

Enteric viruses play an important role in the Brazilian poultry industry due to the economic impact of resulting low yields of broilers, layers, and breeders. The most common enteric viruses affecting commercial flocks in Brazil include Fowl Adenovirus of group I (FAdV-I), Chicken Parvovirus (ChPV), Chicken Astrovirus (CAstV), Avian Nephritis Virus (ANV), Infectious Bronchitis Virus (IBV), Avian Reovirus (AReo), and Avian Rotavirus (ARtV). The aim of this study was to identify single and multiple infections using data obtained from 270 samples from eleven Brazilian states, corresponding to the period between 2010 and 2017...

Although the use of vaccines has controlled enteric diseases in dogs in many developed countries, vaccine coverage is still under optimal situation in Brazil. There is a large population of nonimmunized dogs and few studies about the identification of the viruses associated with diarrhea. To address this situation, stool samples from 325 dogs were analyzed by polymerase chain reaction for the detection of common enteric viruses such as Canine adenovirus (CAdV), Canine coronavirus (CCoV), Canine distemper virus (CDV), Canine rotavirus (CRV) and Carnivorous protoparvovirus 1 (canine parvovirus 2; CPV-2)...
