Coxiella burnetii and Coxiella-like bacteria (CLB) are genetically ecologically distinct despite some genetic similarities. Furthermore, CLB exceptionally diverse widespread in ticks, but rarely detected domestic animals. Since can be transmitted from infected horses by inhalation or coming contact with ticks during activities such as horseback riding, it is necessary to study their prevalence. To the best of our knowledge, this first large-scale nationwide investigation prevalence C. among...
We identified the presence of Toxoplasma gondii in ticks and their host dogs, assess potential role as reservoirs for this pathogen. A total 1,230 feeding were collected from 340 dogs. The tick species included Haemaphysalis longicornis, H. flava, Ixodes nipponensis. Detection T. B1 gene occurred 2 dogs (0.6%) 4 pools (0.9%). Genotyping confirmed I/III genotype. This study is first to report molecular detection both canine hosts. Our findings offer important insights into dynamics...
Salmonella Infantis has recently been one of the most prevalent serotypes in poultry and identified human salmonellosis cases worldwide. Multidrug-resistant (MDR) emerged as a significant threat to both production public health due its increasing prevalence global dissemination. We occurrence an MDR clone broiler flocks Korea, was characterized explore potential genetic causes for high rapid spread production. In total, 220 strains isolated between 2020 2023 from were serotyped, 50 (22.7%)....
Since 2010, the Korea Disease Control and Prevention Agency has established centers at 16 locations to monitor disease vectors pathogens. Here, we examined tick populations understand geographical temporal distribution of severe fever with thrombocytopenia syndrome virus (SFTSV) in 2020. From April November, 63,376 ticks were collected from traps populations, a trap index 41.3. Tick incidence varied October, population peaks observed for nymphs May, adults July, larvae September. The...
There are seven antigenically distinct serotypes of foot-and-mouth disease virus (FMDV), each which has intratypic variants. In the present study, we have developed methods to efficiently generate promising vaccines against or subtypes. The capsid-encoding gene (P1) vaccine strain O1/Manisa/Turkey/69 was replaced with amplified synthetic genes from O, A, Asia1, C, SAT1, SAT2, and SAT3 serotypes. Viruses serotype were rescued successfully. Each chimeric FMDV a replacement P1 showed...
Members of the genus Coxiella can be transmitted from ticks to humans during contact with animals; may thus spread infected horses or humans. In this study, presence burnetii and Coxiella-like endosymbionts (CLE) in found on infested was determined using PCR genotyping. A total 213 were randomly collected 51 (4-5 per horse) raised Jeju Island, Korea, between 2009 2013. All morphologically identified as adult Haemaphysalis longicornis, a predominant tick species widespread Korea. Based...
Pathogenic Escherichia coli (E. coli)-associated infections are becoming difficult to treat because of the rapid emergence antibiotic-resistant strains. Novel approaches required prevent progression resistance and extend lifespan existing antibiotics. This study was designed improve effectiveness traditional antibiotics against E. using a combination gallic acid (GA), hamamelitannin, epicatechin gallate, epigallocatechin, epicatechin. The fractional inhibitory concentration index (FICI) each...
Feral cats that are roaming outside can serve as reservoirs for zoonotic pathogens, negatively impacting public health. They may experience high levels of parasitic infection. Some gastrointestinal protozoa and microsporidia possessing potential in include Cryptosporidium spp., Giardia duodenalis, Blastocystis sp., Enterocytozoon bieneusi, Toxoplasma gondii. Here, we show the infection rates risk factors intestinal detected from shelter on Jeju Island South Korea 2020. Among 158 cats, genes...
Despite nation-wide immunization with O, A, and Asia 1 type vaccines in Republic of Korea, foot-and-mouth disease O occurred again July 2014 after three years months. This virus was a Mya-98 strain the Southeast Asian topotype most similar to identified that circulated East 2014. new deletion 23 amino acids 3A/3B1 region low pathogenic property.
Because the currently available vaccines against foot-and-mouth disease (FMD) provide no protection until 4 to 7 days postvaccination, only alternative method halt spread of FMD virus (FMDV) during outbreaks is application antiviral agents. Combination treatment strategies have been used enhance efficacy agents, and such may be advantageous in overcoming viral mechanisms resistance treatments. We developed recombinant adenoviruses (Ads) for simultaneous expression porcine alpha gamma...
Five outbreaks of foot-and-mouth disease have occurred in South Korea during 2000-2011. Macro-analysis these showed a correlation with countries eastern Asia. Genetic analyses food-and-mouth viruses that are prevalent neighboring countries.
Tick-borne pathogens (TBPs) impose an important limitation to livestock production worldwide, especially in subtropical and tropical areas. Earlier studies Korea have examined TBPs residing ticks animals; however, information on multiple infesting cattle is lacking. This study assessed the prevalence of parasitizing cattle. A total 576 ticks, including 340 adults 236 nymphs, were collected from between 2014 2018. All identified as Haemaphysalis longicornis based their morphological molecular...
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...
The present study was performed to survey the dominant tick populations and molecularly determine pathogenic agents of anaplasmosis in ticks from Gyeongsang, Republic Korea. A total 3825 questing were collected by flagging method 12 sites near animal farms Gyeongsang March October 2021. molecular genomic with stored 70% ethanol detect Anaplasma genes previously described method. monthly incidence varied developmental stages, i.e., nymphs, adults, larvae, each their peaked May, March,...
