African swine fever is one of the most dangerous diseases swine. We confirmed 2019 outbreak in Vietnam by real-time reverse transcription PCR. The causative strain belonged to p72 genotype II and was 100% identical with viruses isolated China (2018) Georgia (2007). International prevention control collaboration needed.
African swine fever virus (ASFV) is the cause of a highly contagious and fatal disease in domestic swine, but no vaccine or effective medicine available so far, therefore, looking for novel anti-ASFV agent very imperative mission. Silver nanoparticles (SNPs) have been recently emerged as antiviral agents against numerous viruses, but, their activity ASFV has not investigated. In this study, ability SNPs was reported. The microbial contamination pig house significantly reduced by spraying SNP...
African swine fever virus (ASFV) genotype II is endemic to Vietnam. We detected recombinant ASFV genotypes I and (rASFV I/II) strains in domestic pigs from 6 northern provinces The introduction of rASFV I/II could complicate ongoing control measures the region.
African swine fever virus (ASFV) recombinant strains pose new challenges for diagnosis and control. This study characterizes genotype I II ASFV identified in northern Vietnam 2023 through whole-genome sequencing comparative genomic analysis. Seven ASFV-positive samples from six provinces were analyzed, with detected Bac Giang, Phu Tho, Vinh Phuc provinces. Isolates showed hemadsorption positivity despite having B646L, indicating their nature. Genome-wide analysis revealed 19 recombination...
In this paper, we report the characterization of a genetically modified live-attenuated African swine fever virus (ASFV) field strain isolated from Vietnam. The isolate, ASFV-GUS-Vietnam, belongs to p72 genotype II, has six multi-gene family (MGF) genes deleted, and an Escherichia coli GusA gene (GUS) inserted. When 6–8-week-old pigs were inoculated with ASFV-GUS-Vietnam oro-nasally (2 × 105 TCID50/pig), they developed viremia, mild fever, lethargy, inappetence, shed in their oral nasal...
Canine parvovirus type 2 (CPV-2) was first identified in the late 1970s; it causes intestinal hemorrhage with severe bloody diarrhea kennels and dog shelters worldwide. Since its emergence, CPV-2 has been replaced new genetic variants (CPV-2a, CPV-2b, CPV-2c). Currently, information about genotype prevalence of Vietnam is limited. In present study, we investigated distribution three regions Vietnam. Rectal swabs were collected from 260 dogs suspected infection northern, central, southern...
African swine fever (ASF) is a devastating disease of and the most important for pork industry. Since outbreaks in 2007 Caucasian region, it has been spreading to West East quite swiftly. In this study we have analysed clinical signs pathological features first on ASF Vietnam 2019, caused by an isolated with 100% similarity genotype II (p72) isolates from Georgia China 2018. The onset peracute acute course high mortality. Some animals showed very unspecific other showing severe hyperthermia,...

African swine fever virus (ASFV) causes a highly contagious and fatal disease affecting both domesticated wild pigs. Substandard therapies inadequate vaccinations cause severe economic damages from pig culling removal of infected carcasses. Therefore, there is an urgent need to develop rapid point-of-use approach that assists in avoiding the spread ASFV reducing loss. In this study, we developed colorimetric sensing platform based on dual enzymatic amplification combined clustered regularly...
African swine fever virus (ASFV) continues to spread globally causing severe economic losses the pig farmers. Vietnam licensed two live attenuated vaccines based on ASFV strains ASFV-G-ΔI177L and ASFV-G-ΔMGF, control ongoing ASF outbreaks. In 2023, newly emerging highly virulent recombinant viruses containing genetic elements from both p72 genotype I II (rASFV I/II) were reported Northern Vietnam. This study evaluated if vaccine able protect pigs against rASFV I/II strain...
Abstract Swine acute diarrhea syndrome coronavirus (SADS-CoV) is a novel porcine that was recently identified in southern China 2017. At present, there lack of nationwide epidemiological investigations the newly emerged SADS-CoV. Because Vietnam geographically adjacent to China, many diseases have spread from Vietnam. To assess SADS-CoV transmission Vietnam, we conducted retrospective study detect samples collected pig farms northern Among 69 fecal tested, 5 were positive for The spike gene...
Abstract Five hundred four fecal specimens, collected between 2004 and 2006 from young children with acute diarrhea, were screened for rotavirus by ELISA VP6‐specific antibody. Of these samples, 394 (78.2%) confirmed as group A they underwent G‐ P typing using a combination of ELISA, RT‐PCR, sequence analysis methods. The dominant circulating G serotype was G1 (35.6%) followed G3 (26.4%), G4 (14.7%), G2 (11.9%). There low prevalence G9 (1.0%) unusual type rotavirus, in particular, G12 (0.5%)...
: African swine fever virus (ASFV) continues to spread globally, causing severe economic losses pig farmers. Vietnam licensed two live attenuated vaccines based on the ASFV strains ASFV-G-ΔI177L and ASFV-G-ΔMGF control ongoing ASF outbreaks. In 2023, newly emerging highly virulent recombinant viruses (rASFV I/II) containing genetic elements from both p72 genotype I II were reported Northern Vietnam.
The human rotavirus G1P[8] strain is one of the most common rotaviruses worldwide, including Korea. Six Korean rotaviruses, isolated using cell culture techniques, were characterized on basis sequence differences in VP7, VP4, VP6, and NSP4 genes to elucidate evolutionary relationships community. All strains had a long RNA electropherotype, supported by VP6 gene analysis, clearly associated with subgroup II specificity. phylogenetic analysis VP7 sequences showed that they all clustered into...
African swine fever (ASF) has spread across the globe and reached closer to North America since being reported in Dominican Republic Haiti. As a result, surveillance measures have been heightened utility of alternative samples for herd-level monitoring dead pig sampling investigated. Passive based on investigation pigs, both domestic wild, plays pivotal role early detection an ASF incursion. The World Organization Animal Health (OIE)-recommended pigs are spleen, lymph nodes, bone marrow,...
