Prevalence and antimicrobial resistance profiles of Salmonella serotypes isolated from 7 chicken meat brands produced by different integrated broiler operations in Korea were determined. In total, 210 samples collected retail supermarkets Seoul, South Korea, analyzed for the presence Salmonella. Of samples, overall prevalence was 22.4%. Enteritidis dominant serovar, with an isolation rate 57.4% Salmonella-positive chickens, followed Montevideo. isolates frequently resistant to various...
Abstract A reassortant clade 2.3.4.4 avian influenza A(H5N6) virus was isolated from a fecal sample of Mandarin duck (Aix galericulata) in South Korea during October 2016. This genetically similar to H5N6 subtype isolates China, Vietnam, Laos, and Hong Kong, including human isolates.
In 2014, the highly pathogenic avian influenza (HPAI) virus H5N8 triggered outbreaks in wild birds and poultry farms South Korea. present study, we investigated pathogenicity of HPAI virus, belonging to clade 2.3.4.4, different species poultry. For this, examined clinical signs viral shedding levels following intranasal inoculation 3-week-old commercial layer chickens quails, 10-week-old Korean native chickens, 8-week-old Muscovy ducks. Intranasal with 10(6.0) viruses at 50% egg-infective...
Highly pathogenic avian influenza A(H5N8) viruses were isolated from migratory waterfowl in South Korea during fall 2014-winter 2015, a recurrence after initial introduction winter 2014. These reappeared phylogenetically distinct isolates circulating poultry farms Korea.
ABSTRACT In this study, we developed Newcastle disease virus (NDV) virus-like particles (VLPs) expressing NDV fusion (F) protein along with influenza matrix 1 (M1) using the insect cell expression system. Specific-pathogen-free chickens were immunized oil emulsion VLP vaccines containing increasing dosages of VLPs (0.4, 2, 10, or 50 μg VLPs/0.5-ml dose). Three weeks after immunization, immunogenicity was determined a commercial enzyme-linked immunosorbent assay (ELISA) kit, and lethal...
The 3D8 single chain variable fragment (scFv) is a mini-antibody that causes unusual sequence-independent nuclease activity against all types of nucleic acids. We used recombinant lentiviruses to generate transgenic chickens expressing the scFv gene under control chicken β-actin promoter. From 420 injected embryos, 200 chicks (G0) hatched and were screened for using PCR, 15 identified as birds transgene in their semen. G0 founder mated with wild-type hens produce seven (G1). expression...
The H5 subtype highly pathogenic avian influenza virus (HPAIV) has been introduced to South Korea every 2 or 3 years via wild migratory waterfowls, causing devastating damages the poultry industry. Although most and economic losses by HPAIV are focused on chicken layers, domestic ducks known play a major role in farm-to-farm transmission. However, vaccine studies have performed with oil-emulsion inactivated vaccines. In this study, we developed live recombinant Newcastle disease...
The purpose of this study was to identify the microbial community raw milk samples before and after UV-C irradiation establish fundamental data on treatment improve safety shelf life milk. Metagenomic analysis revealed that Lactococcus spp., Lactobacillus Staphylococcus spp. were dominant genera in milk, while Pseudomonas became more prevalent 14 days refrigerated storage. microorganisms isolated using selective media identified as Serratia quinivorans 4364 Latilactobacillus curvatus DSM...
Influenza epidemics frequently and unpredictably break out all over the world, seriously affect breeding industry human activity. Inactivated live attenuated viruses have been used as protective vaccines but exhibit high risks for biosafety. Subunit enjoy biosafety specificity a few weak points compared to inactivated virus or vaccines, especially in low immunogenicity. In this study, we developed new subunit vaccine platform potent, adjuvant-free, multivalent vaccination. The ectodomains of...
Highly pathogenic avian influenza (HPAI) and Newcastle disease (ND) are considered as the most devastating poultry infections, owing to their worldwide distribution economical threat. Vaccines have been widely used control these diseases in industry endemic countries. However, vaccination policy without differentiating infected animals from vaccinated (DIVA) makes virus surveillance difficult. In this study, we developed a bivalent virus-like particle (VLP) vaccine that is composed of...
Interferon gamma (IFN-γ), an immunoregulatory cytokine, is known to control many microbial infections. In a previous study, chicken interferon (chIFN-γ) was found be up-regulated following avian influenza virus (AIV) infection in specific pathogen-free chickens. We aimed investigate whether the pre-immune state induced by chIFN-γ could generate antiviral response against virus. generated chIFN-γ-expressing plasmid and transfected it into embryo fibroblasts (CEFs) then infected cells with...
Highly pathogenic avian influenza (HPAI) is considered as one of the most devastating poultry diseases. It imperative to immediately report any known outbreaks World Organization for Animal Health. Early detection infected birds paramount importance control virus spread, thus minimizing associated economic loss. In this study, thermal imaging camera devices were used detect change in maximum surface temperature (MST) chickens ( n = 5) and ducks 2) an early indicator experimental HPAI...
