Abstract During October 2022–March 2023, highly pathogenic avian influenza (HPAI) A(H5N1) clade 2.3.4.4b virus caused outbreaks in South Korea, including 174 cases wild birds. To understand the origin and role of birds evolution spread HPAI viruses, we sequenced 113 isolates from performed phylogenetic analysis. We identified 16 different genotypes, indicating extensive genetic reassortment with viruses Phylodynamic analysis showed that were most likely introduced to southern...
We isolated novel reassortant avian influenza A(H5N6) viruses containing genes from clade 2.3.4.4b H5N1 virus and low pathogenicity in carcasses of whooper swans bean geese South Korea during December 2023. Neuraminidase gene was a H5N6 infecting poultry humans China.
The African swine fever virus (ASFV) was first detected in wild boar the Demilitarized Zone, a bordered area between South and North Korea, on 2 October 2019. Phylogenetic analyses of ASFV genes encoding p72 CD2v indicated that causative strain belongs to genotype II serogroup 8, respectively, contained additional tandem repeat sequences I73R I329L protein genes.

Highly pathogenic avian influenza (HPAI) subtype H5Nx viruses of the A/Goose/Guangdong/1/1996 (Gs/Gd) lineage have led to substantial economic losses within poultry industry and represent an ongoing public health threat [1]. The Gs/Gd H5 not only evolved into ten primary clades 0-9 with their subclades but also reassorted other A [2; 3; 4]. Notably, since 2020, clade 2.3.4.4b HPAI H5N1 caused outbreaks across a broad geographic range, including Asia, Europe, Africa, North America, South...
Yakutia, the largest breeding ground for wild migratory birds in Northeastern Siberia, plays a big role global ecology of avian influenza viruses (AIVs). In this study, we present results virological surveillance conducted between 2018 and 2023, analyzing 1970 cloacal swab samples collected from 56 bird species. We identified 74 AIVs H3N6, H3N8, H4N6, H5N3, H7N7, H10N3, H11N9 subtypes Anseriformes order. Phylogenetic analysis showed that isolates belong to Eurasian lineage have genetic...
Ticks are major vectors of numerous pathogens, and their public health significance is increasing due to climate change the expanding involvement wildlife hosts. In Korea, Korean water deer (KWD, Hydropotes inermis argyropus) widely distributed considered a key wild host for ticks, potentially serving as reservoir diverse tick-borne diseases (TBDs). To examine geographical temporal distribution TBDs in this species, 1035 spleen samples were collected from KWDs across 12 regions between April...
Blastocystis is a genus of parasitic protozoans that live in humans, mammals, and birds which has been widely studied due to its low host specificity. Limited data are available, however, regarding presence wildlife, particularly South Korea. Contact between wild boars (Sus scrofa) livestock or humans steadily increased as venture down from the mountains farms residential areas. In this study, we examined status subtypes (STs) Korea confirmed zoonotic potential. From March 2016 November...
African swine fever virus variants with different numbers of a 10-bp tandem repeat were isolated in South Korea soon after being identified wild boar. The short emergence periods and sympatric distributions within narrow geographical region suggest that the sporadically generated pre-existing viral population.
Bats are hosts for many ectoparasites and act as reservoirs several infectious agents, some of which exhibit zoonotic potential. Here, species bats bat flies were identified screened microorganisms that could be mediated by flies. Bat on the basis their morphological characteristics. associated with initially morphologically further at genus level analyzing cytochrome c oxidase subunit I gene. Different vector-borne pathogens endosymbionts using PCR to assess all possible relationships among...
Severe fever with thrombocytopenia syndrome virus (SFTSV) is a zoonotic, tick-borne RNA of the genus Bandavirus (Family Phenuiviridae), mainly reported in China, Japan, and Republic Korea (Korea). For purpose this study, total 3,898 adult nymphal ticks species Haemaphysalis longicornis (94.2%), flava (5.0%), Ixodes nipponensis (0.8%), 1 specimen ovatus, were collected from Deogyusan National Park, Korea, between April 2016 June 2018. A single-step reverse transcriptase-nested PCR was...
Severe fever with thrombocytopenia syndrome virus (SFTSV) is tick-borne and causes this disease (SFTS) in humans. We determined the complete genome sequences of two SFTSV strains isolated from serum a human SFTS dog asymptomatic infection using reverse transcription rapid amplification cDNA ends PCR.
Blastocystis is a protozoan parasite commonly detected in the intestinal tract of humans and animals. It has been actively studied worldwide; however, information on limited Korea. Because there an increasing concern about contact between wildlife domestic animals or humans, we assessed infection status zoonotic potential Korean water deer (KWD, Hydropotes inermis argyropus) using genotyping phylogenetic analysis. A total 125 fresh fecal samples were collected from KWD which killed by...
Highly pathogenic avian influenza (HPAI) subtype H5Nx viruses of the A/Goose/Guangdong/1/1996 (Gs/Gd) lineage have caused substantial economic losses in poultry industry and represent a significant public health concern (1). Since its first detection 1996, it has diverged into 10 genetically distinct hemagglutinin (HA) clades (0-9) subclades (2). Of these, clade 2.3.4.4b HPAI H5N1 outbreaks wild birds, poultry, mammals broad geographical regions including Asia, Europe, Africa, North America,...
Abstract The activated methyl cycle (AMC) is responsible for the generation of S -adenosylmethionine (SAM), which a substrate N -acylhomoserine lactone (AHL) synthases. However, it unknown whether AHL-mediated quorum sensing (QS) plays role in metabolic flux AMC to ensure cell density-dependent biosynthesis AHL cooperative populations. Here we show that QS controls homeostasis critical and cellular methylation Burkholderia glumae , causal agent rice panicle blight. Activation genes encoding...
Enterocytozoon bieneusi, an important microsporidian fungus, causes chronic diarrhea in humans and animals worldwide. Out of the 502 fecal samples from wild boars, 13 were positive for E. bieneusi internal transcribed spacer region, with a prevalence 2.6%. Six genotypes, D, EbpC, four novel KWB1-KWB4, identified zoonotic potential. Genotypes D (subgroup 1a) EbpC 1d) first reported Korean swine Korea, respectively; KWB1-KWB4 1e) most prevalent this study. Because genotypes have been...
Toxoplasma gondii is a ubiquitous zoonotic parasite with wide range of warm-blooded animals as intermediate hosts, where the transmission primarily occurs through ingesting T. oocysts in environment. Hence, inhabiting geographical can be sentinels for environmental contamination oocysts. The aim this study was to determine seroprevalence two generalist ungulates Republic Korea (ROK), wild boar (Sus scrofa) and Korean water deer (Hydropotes inermis argyropus), identify risk factors associated...
