Honey bees play an important role in the pollination of crops and wild plants provide products to humans. Pathogens parasites are main factors that threaten beekeeping South Korea. Therefore, a nationwide detection 14 honey bee pathogens, including (phorid flies, Nosema ceranae, Acarapis woodi mites), viruses, bacteria, fungal was conducted from 2017 2021 country. The infection rate trend each pathogenic agent were determined. A total 830 samples Apis cerana (n = 357) A. mellifera 473)...
Lake Sinai Virus (LSV) is an emerging pathogen known to affect the honeybee ( Apis mellifera ). However, its prevalence and genomic characteristics in Republic of Korea (ROK) remain unexplored. This study aimed assess analyze LSVs by examining 266 samples from ROK. Our findings revealed that LSV exhibited highest infection rate among pathogens observed Korean apiaries, particularly during reported period severe winter loss (SWL) A . apiaries 2022. Three genotypes– 2, 3, 4 –were identified...
Apis mellifera filamentous virus (AmFV) is a double-stranded DNA that infects bees. To our knowledge, this the first comprehensive study aiming to detect and analyse genetic diversity prevalence of AmFV in Korean honeybee colonies. Phylogenetic analysis based on baculovirus repeat open reading frame-N gene (Bro-N) sequences revealed isolates from Republic Korea (ROK) fell into two distinct lineages, with origins Switzerland China, nucleotide similarities 98.3% 98.2%, respectively. Our...
The honey bee is an important pollinator of wild plants and crops provides various useful products for humans. Infestations by mites damage the bees' health, decrease their lifespan, increase viral susceptibility. In this study, surveys were conducted throughout South Korea in 2019 to investigate status mite infestation. Mite samples collected species identification, estimation infestation levels from 47 apiaries 12 regions was conducted. identified morphological characteristics genetic...
The poultry red mite (PRM), Dermanyssus gallinae, significantly impacts the health of egg-laying hens. Mites feed on blood infested chickens and have a great economic impact industry. Chemical treatment mites raises concerns about their resistance to miticides residues in eggs poultry. Biocontrol using entomopathogenic fungi is expected be chemical-free strategy for reducing PRM infestations. Therefore, present study aimed investigate effects various fungal species collected South Korea...
Background The microsporidian parasite Nosema ceranae is a global problem in honeybee populations and known to cause winter mortality. A sensitive rapid tool for stable quantitative detection necessary establish further research related the diagnosis, prevention, treatment of this pathogen. Objectives present study aimed develop method that incorporates ultra-rapid real-time polymerase chain reaction (UR-qPCR) enumeration N. infected bees. Methods procedure UR-qPCR was developed, advantages...
Abstract Honey bees are important pollinators for the conservation of ecosystem and agricultural products provide a variety human use, such as honey, pollen, royal jelly. Sacbrood disease (SD) is devastating viral in Apis cerana ; an effective preventive measure SD urgently needed. In this study, relationship between gut microbiome honey was investigated by pyrosequencing. Results revealed that sacbrood virus (SBV)-resistant A. strains harbour unique acetic acid bacterium, Bombella intestini...
Abstract Background American foulbrood (AFB) disease caused by Paenibacillus larvae is dangerous, and threatens beekeeping. The eco-friendly treatment method using probiotics expected to be the prospective for controlling this pathogen in honey bees. Therefore, study investigated bacterial species that have antimicrobial activity against P. . Results Overall, 67 strains of gut microbiome were isolated identified three phyla; isolates had following prevalence rates: Firmicutes 41/67 (61.19%),...
Abstract Migratory birds disperse ticks and associated tick-borne pathogens along their migratory routes. Four selected of medical importance ( Coxiella burnetii, Rickettsia spp., Francisella tularensis, Toxoplasma gondii ) were targeted for detection in 804 (365 pools) collected from at Hong Heuksan Islands the Republic Korea (ROK) 2010 to 2011 2016. detected 1/365 (0.27%) 34/365 (9.32%) pools ticks, respectively. T. five rickettsial species recorded first time ROK. The R. monacensis,...
Although silver is known to be a broad-spectrum biocidal agent, the effects of this metal against Sacbrood virus have not yet been investigated.In study, we evaluated efficacy ions natural Korean sacbrood (KSBV) infection Apis (A.) cerana.Ten KSBV-infected colonies containing A. cerana with similar strength and activity were selected from an apiary located in Bosung-gun (Korea).Among these, five randomly assigned treatment group that was fed sugar syrup 0.2 mg/L ions.The other untreated...
There is a lack of comprehensive studies on the seroprevalence tick-borne pathogens in Republic Korea. Therefore, aim this study was to investigate seroprevalences Anaplasma spp. (A. phagocytophilum/A. platys), Borrelia burgdorferi sensu lato, Babesia gibsoni, Ehrlichia (E. canis/E. ewingii), and chaffeensis dogs across Korea 2017 2018. A total 2215 serum samples collected from 938 companion dogs, 969 shelter 308 military working were examined using commercial enzyme-linked immunosorbent...
Mites of the genus Tyrophagus (Acari: Acaridae) are among most widely distributed mites. The species in this cause damage to stored products and crops, pose a threat human health. However, influence spp. apiculture remains unknown. In 2022, study focusing on identification within five apiaries was conducted Chungcheongnam Province, Republic Korea. Its specific objective investigate presence mites response reported high mortality honey bee colonies area. Morphological phylogenetic analysis...
Apis mellifera, especially weak ones, are highly vulnerable to Carpoglyphus lactis mites, which can rapidly infest and consume stored pollen, leading weakened colonies potentially colony collapse. This study aimed ascertain investigate the prevalence of this mite in honeybee across 9 provinces Republic Korea (ROK). A total 615 were collected, from 66 apiaries during spring 58 summer 2023. 1,242 bp segment Cytochrome c oxidase subunit 1 (COI) gene was amplified using polymerase chain reaction...
In this study, we identified a new strain of the genus Neocypholaelaps from beehives Apis mellifera colonies in Republic Korea (ROK). The Neocypholaelap sp. KOR23 mites were collected hives honeybee apiaries Wonju, Gangwon-do, May 2023. Morphological and molecular analyses based on 18S 28S rRNA gene regions conclusively that these belong to , closely resembling APGD-2010 was first isolated United States. presence 9 25 pathogens mite samples suggests may act as an intermediate vector carrier...
Background: Tick-borne diseases (TBDs) can be fatal to humans as well animals causing severe economic losses globally livestock industries. Many countries conduct regular surveillance of TBDs in livestock. Serological and molecular was carried out the Republic Korea. However, there are not a lot data on analyses anaplasmosis Korean native goats correlation with rearing methods seasons. Methods: In this study, Ulsan city were tested for by PCR 16S rRNA sequencing. A total 452 goat blood...
Acarapis mites, including woodi, externus, and dorsalis, are parasites of bees which can cause severe damage to the bee industry by destroying colonies decreasing honey production. All 3 species prevalent throughout many countries UK, USA, Iran, Turkey, China, Japan. Based on previous reports mites occurring in northeast Asia, China Japan, we investigated a survey mite infestations Korean apiaries. A total 99 Apis mellifera were sampled from 5 provinces. The head thorax 20 each colony...
The outbreak of human toxoplasmosis can be attributed to ingestion food contaminated with Toxoplasma gondii. Toxoplasmosis recently increased in domestic and stray dogs cats. It prompted studies on the zoonotic infectious diseases transmitted via these animals. Sero- antigen prevalences T. gondii cats were surveyed using ELISA PCR, B1 gene phylogeny was analyzed this study. antibodies measured sera 403 cats, 947 dogs, 909 2,412 collected at nationwide regions, Korea from 2017 2019.
