SARS-CoV-2 transmission and epidemic potential is related to the population's immunity levels. As such, assessing different regions' preexisting immune responses important understand of emerging variants.
This study aimed to investigate the effects of Clostridium butyricum as a dietary probiotic supplement in fishmeal based diet on growth, gut microbiota and immune performance marron (Cherax cainii). Marron were randomly distributed into two different treatment groups, control fed group. After 42 days feeding trial, results revealed significant (P < 0.05) increase growth due number moults probiotics. The also significantly enhanced total haemocyte counts (THC), lysozyme activity haemolymph...
Between 2016 and 2019, 265 cases of Zika virus (ZIKV) infection were reported in Vietnam, predominantly southern Vietnam. In 2016, a case ZIKV-associated microcephaly was confirmed the Central Highlands, several members infant's family to be infected with ZIKV. The study aims determine level immunity ZIKV general population epidemic region.A total 879 serum samples collected from 801 participants between January 2017 July 2018, during after tested for anti-ZIKV immunoglobulin M (IgM) G...
Abstract Computer vision has found many applications in automatic wildlife data analytics and biodiversity monitoring. Automating tasks like animal recognition or detection usually require machine learning models (e.g., deep neural networks) trained on annotated datasets. However, image datasets built for general purposes fail to capture realistic conditions of ecological studies, existing collected with camera-traps mainly focus medium large-sized animals. There is a lack small-sized the...
Dengue virus (DENV) is a member of insect vector-borne viruses, and it causes dengue fever. Southeast Asia the epi-center fever in world. The characterization essential to identify transmission evolution DENV.In 2017, there was an outbreak type 1 (DENV1) northern Vietnam neighboring countries. To genetic character area, we conducted whole-genome sequencing analysis on samples positive for DENV1 along with real-time PCR.In total, 1026 blood were collected from patients suspected Ha Nam Hai...
Dengue virus (DENV) replication between mosquito and human hosts is hypothesized to be associated with viral determinants that interact in a differential manner hosts. However, the understanding of inter-host drive DENV growth limited. Through use clinical isolates, we identified an amino acid variation Ala, Met Val at position 116 DENV-1 NS4B. While proportion NS4B-116V variant remained constantly high serial passages cell line, populations NS4B-116M NS4B-116A variants became dominant after...
Dengue virus (DENV) infection is a major cause of morbidity and mortality in Vietnam, the incidence higher more consistent southern part country. This study investigated circulation DENV serotypes, viremia levels, immunological status, cytokine with disease severities among children infected 2017 Ho Chi Minh City, Southern Vietnam. Acute convalescent serum samples were collected from clinically diagnosed dengue children. They confirmed to have by NS1 antigen, IgM IgG ELISAs, isolation,...
Antibodies are critical responses to protect the host from dengue virus(DENV) infection. target DENV by two pathologic mechanisms: virus neutralization and infection enhancement. In patients, absence of neutralizing activity in presence FcγR implies that infection-enhancing hampers antibodies, which could potentially lead symptomatic presentations severe clinical outcomes. A total 100 pair serum samples adult healthy volunteers were obtained during season Ha Noi 2015 for evaluation activity....
The World Health Organization has designated Zika virus (ZIKV) as a dangerous, mosquito-borne flaviviral pathogen that was recently found to be responsible for dramatically increased number of microcephaly cases and other congenital abnormalities in fetuses newborns. There is neither vaccine prevent nor drug treat ZIKA infections, at the present time. Berberine (BBR) promising approved by FDA against dengue virus, BBR derivatives are great interest antiviral development. In this study, we...
Herpesviruses exist in nature within each host animal. Ten herpesviruses have been isolated from bats and their biological properties reported. A novel bat alphaherpesvirus, which we propose to name "Pteropus lylei-associated alphaherpesvirus (PLAHV)," was urine of the fruit Pteropus lylei Vietnam characterized. The entire genome sequence determined be 144,008 bp length predicted include 72 genes. PLAHV assigned genus Simplexvirus with other alphaherpesviruses pteropodid Southeast Asia...
Infectivity and neutralizing antibody titers of flavivirus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are frequently measured using the conventional plaque assay. While assay is useful in determination infectivity, assays generally possess lower sensitivity time-consuming compared to nucleic acid amplification tests. In this study, a microcrystalline cellulose (MCC), Avicel, was evaluated as an alternative virus overlay medium, methylcellulose, for The performed dengue...
Japanese encephalitis virus (JEV) is classified into 5 genotypes (GI, GII, GIII, GIV, and GV), the GI GIII strains are most widely distributed in JE endemic areas. In recent years, GV JEV has been detected China Korea, suggesting that may invade other areas, including Vietnam, more attention should be paid to circulating these this study, we investigated neutralization ability of sera collected from 22 Vietnamese patients with who lived northern Vietnam against strains. cases, ratios titer...
Polychlorinated dibenzo-p-dioxins (PCDD) and polychlorinated dibenzofurans (PCDF) are the most toxic substances among group of unintentional persistent organic pollutants (U - POP) generated from many sources, in which domestic industrial waste incinerators highest emission risk. Assessment pollution potential dioxin/furan emissions developing countries, including Vietnam, is still limited; especially in-depth studies on content characteristics PCDD/PCDF emitted into atmosphere. Therefore,...
This study aims to identify medium components (carbon source, carbon concentration, nitrogen source) and fermentation conditions (temperature, pH) enhance the resistance against Fusarium oxysporum f. sp. cubenseTropical Race 4 (Foc Tr4), causing Panama wilt disease of Streptomyces VNUA116 (VNUA116). By using agar well diffusion method, it was determined that strain has strong anti-fungal pathogen activities FocTr4 under nutrients: YIM 301 medium, source CB1 (soluble starch 40 g/l: D-glucose...
The aim of the study is to optimize extraction process from Shengmai San using Response Surface Methodology (RSM). factors ethanol concentration, temperature, and time have an impact on performance (PE) anti-free radical activity DPPH %I (p<0.05). method used was regression analysis experimental data, resulting in a second-degree polynomial model with relatively strong correlation variance that statistically significant (p<0.05), high R2, R2adj values indicating reliable suitable for...
Phytochemical investigation of the leaves Pandanus amaryllifolius led to isolation three shikimate esters including methyl (1), n-butyl (2), and 5-epi-shikimate (3), together with vomifoliol (4), a megastigmane, D-galactopyranoside (5)-a glycoside. Structures isolated compounds were elucidated by spectroscopy data.
The RT-qPCR method remains the gold standard and first-line diagnostic for detection of SARS-CoV-2 flaviviruses, especially in early stage viral infection. Rapid accurate is a starting point containment COVID-19 pandemic flavivirus outbreaks. However, shortage reagents supplies, resource-limited countries that experience co-circulation are limitations may result lesser availability RT-qPCR-based tests. In this study, utility RNA-free extraction methods was assessed direct DENV-2...
