First contribution to water buffalo (Bubalus bubalis) type-I/III interferons – induced Mx1 detection and anti-viral activity

Introduction Myxovirus resistance protein 1 (Mx1) is a type I/III interferons-induced protein conferring the hosts an antiviral property against several viruses. The protein is also found to be a potential...

Application of a real-time PCR assay for the detection of Ascaris suum DNA in the liver of experimentally infected chickens

Abstract This study aimed to evaluate the sampling method for the detection of Ascaris suum larval DNA in chicken livers using real-time PCR. Chickens were inoculated with A. suum eggs of a single dose (Group A) or repeatedly low doses (Group B). White spots

Triple gene editing in porcine embryos using electroporation alone or in combination with microinjection

Abstract Background and Aim: We previously developed the gene-editing by electroporation (EP) of Cas9 protein method, in which the CRISPR/Cas9 system was introduced into porcine in vitro fertilized (IVF) zygotes through EP to disrupt a target gene. This

Molecular and phylogenetic analysis of Vietnamese canine parvovirus 2C originated from dogs reveals a new Asia-IV clade

Abstract Canine parvovirus type 2 (CPV-2) is a small, single-stranded DNA virus causing fatal haemorrhagic enteritis in dogs. Currently, CPV-2 is classified into CPV-2a, CPV-2b and CPV-2c based on genetic variation in the VP2 gene. The CPV-2c variant has

Detection and genotyping of bovine leukemia virus (BLV) in Vietnamese cattle

Abstract Bovine leukemia virus (BLV) belongs to the genus, Deltaretrovirus of the family, Retroviridae and it is the causative agent of enzootic bovine leukosis. The prevalence of BLV in three provinces in the Red River Delta Region in the North of

Isolation, characterization and application of a polyvalent phage capable of controlling Salmonella and Escherichia coli O157:H7 in different food matrices

Abstract Salmonella Enteritidis, Salmonella Typhimurium, and Escherichia coli O157:H7 are the most important foodborne pathogens, causing serious food poisoning outbreaks worldwide. Bacteriophages are increasingly considered as novel antibacterial agents

Evaluation of Benzguinols as Next-Generation Antibiotics for the Treatment of Multidrug-Resistant Bacterial Infections

Abstract Our recent focus on the “lost antibiotic” unguinol and related nidulin-family fungal natural products identified two semisynthetic derivatives, benzguinols A and B, with unexpected in vitro activity against Staphylococcus aureus isolates either

Isolation and application of bacteriophages alone or in combination with nisin against planktonic and biofilm cells of Staphylococcus aureus

Abstract Staphylococcus aureus is a notorious foodborne pathogen since it has ability to produce variety of toxins including heat-stable enterotoxin, form biofilm, and acquire resistance to antibiotics. Biocontrol of foodborne pathogens by lytic

Comparison of Blastocyst Development between Cat-Cow and Cat-Pig Interspecies Somatic Cell Nuclear Transfer Embryos Treated with Trichostatin A

Abstract We previously demonstrated that the histone deacetylase inhibitor, trichostatin A (TSA), improves the development of cat-cow interspecies somatic cell nuclear transfer (iSCNT) embryos. In this study, we investigated if 50 nM TSA treatment for 24 h

Anaplasma marginale and A. platys Characterized from Dairy and Indigenous Cattle and Dogs in Northern Vietnam

Abstract Anaplasma marginale and A. platys were detected and characterized (16S rDNA sequence analysis) from dairy and indigenous cattle, and the latter in domestic dogs in Vietnam. A phylogenetic tree was inferred from 26 representative strains/species

Nasal Swab– a New Tool for the Detection of Porcine Respiratory Disease Complex in Natural Infected Pigs

Abstract The objectives of the present study were to determine whether nasal swab could be used for the detection of PRDC in naturally infected pigs. Fifteen piglets were used in this study. Serum, oral fluid, nasal swab, lung, tonsil and pulmonary lymph node

Chronic Royal Jelly Administration Induced Antidepressant-Like Effects Through Increased Sirtuin1 and Oxidative Phosphorylation Protein Expression in the Amygdala of Mice

Abstract Background: Major depressive disorder (MDD) is a common psychological disorder worldwide. However, one-third of patients with MDD are resistant to the present anti-depressant medicine, which regulates monoamine contents in the brain. Thus, another

Establishment of an In Vitro Model of Persistent Chicken Anemia Virus Infection

Abstract Persistent infection of chicken anemia virus (CAV) in chickens has been suspected to result in immunosuppression and exogenous virus contamination within vaccine production. However, no direct evidence for persistent CAV infection has thus far been

Chicken anemia virus in northern Vietnam: molecular characterization reveals multiple genotypes and evidence of recombination

Abstract Chicken anemia virus (CAV) has a ubiquitous and worldwide distribution in the chicken production industry. Our group previously reported a high seroprevalence of CAV in chickens from northern Vietnam. In the present study, tissue samples collected

Factors associated with prolonged farrowing duration in sows

Abstract The present study was conducted to investigate the effect of parity number, gestation length, litter size and average piglets’s birthweight on the prolonged farrowing duration (PFD, farrowing duration ≥5h) in sows. Data were collected from 981

Establishment of a serodiagnosis system for the detection of Toxocara spp. and Ascaris suum infection in chickens

Abstract Chickens are considered to act as paratenic hosts for agents, Toxocara canis, T. cati and Ascaris suum; which cause ascarid larva migrans syndrome (ascarid LMS) in humans. In addition, they are the definitive host for Ascaridia galli, considered not

Effect of vaginal discharge in sows on diarrhea in sucking piglets

The present study was conducted to investigate the effect of postparturient vaginal discharge in sows on the diarrhea in sucking piglets. In total, 67 sows and 762 sucking piglets of Landrace x Yorkshire breed were enrolled in this study. Duration of
