Balantioides coli is a zoonotic protozoan parasite whose main reservoir pigs. Recent studies have shown that B. variant A but not B has potential. While infection been reported in different animals and countries, the prevalence of limited due to lack molecular information. Therefore, this study investigated domestic pigs Korea assessed its total 188 pig fecal samples were collected from slaughterhouses Korea. was identified by microscopy methods. 79 (42.9%) 174 (94.6%) polymerase chain...
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 describe for the first time detection of Coxiella-like bacteria (CLB), Theileria luwenshuni, and T. ovis endosymbionts in blood-sucking deer keds. Eight keds attached to a Korean water were identified as Lipoptena fortisetosa (Diptera: Hippoboscidae) by morphological genetic analyses. Among assessed, CLB, L. PCR nucleotide sequencing. Based on phylogeny, CLB 16S rRNA sequences classified into clade B, sharing 99.4% identity with from Haemaphysalis longicornis South Korea. Although...
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...
The beneficial health promoting effects of ginseng from vitalizing the body to enhancing long life have been well explored very rapidly in past few years. Up till now many ginsenosides discovered for their marvelous therapeutic effects. However during three years, a novel compound has discovered, called gintonin, that differs other on basis its signal transduction and chemical nature. Gintonin widely studied anti-Alzheimer's disease activities neuropathies. However, anti-inflammatory...
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...
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...
Abstract Coal fly dust (CFD)-induced asthma model is used as an ambient particulate matter of serious pulmonary damage. We aimed to evaluate the effects a combination ginseng and Salvia plebeia R. Br extract (KGC-03-PS; KG3P) its individual components (hispidulin, nepetin rosmarinic acid) in CFD-induced mouse airway inflammation (asthma). also evaluated signal transduction by KG3P alveolar macrophage cell line, MH-S cells. In vitro, inhibited nitric oxide production expression...
The glyoxalase pathway, which includes two enzymes, 1 and 2 (Glo1 Glo2), is a ubiquitous cellular system responsible for the removal of cytotoxic methylglyoxal produced during glycolysis. Protozoan parasites, including Toxoplasma gondii (T. gondii) tachyzoites, produce because increased glycolytic fluxes. A Glo1 inhibitor such as curcumin could be considered drug candidate anti-protozoan, anti-inflammatory, anti-cancer therapy.The T. gene (TgGlo1) was cloned recombinant protein produced....
Lyme disease is a tick-borne zoonotic infectious caused by Borrelia burgdorferi. The present study assessed the infection status of B. burgdorferi among horses reared in Korea using ELISA and PCR. Between 2009 2013, blood samples were collected from 727 throughout Korea. Data for each animal including age, gender, breed, region sample collection used epidemiological analysis. Overall, 38 (5.2%; true prevalence: 5.5%) seropositive ELISA. There statistically significant differences according...
We developed a qPCR assay based on the β-tubulin gene sequence for shrimp microsporidian parasite Enterocytozoon hepatopenaei (EHP). This reacted with hepatopancreas (HP) of EHP-infected shrimps, and highest copy numbers were found in HP feces samples from Southeast Asian countries (106-108 copies mg-1), while Latin America, Artemia, EHP-contaminated water showed lower amounts (101-103 mg-1 or mL-1 water). No false positive was normal genome, live feeds, other parasitic diseases. tool will...
Ticks are blood-sucking ectoparasites that act as vectors for transmission of various pathogens. The purpose this study was to assess tick-borne bacteria, whether pathogenic or not, in ticks distributed Korea using 16S rRNA metabarcoding and confirm the results by PCR. Questing were collected from four provinces 2021 flagging method. After pooling DNAs 61 tick pools (including 372 ticks), bacterial V3–V4 hypervariable region amplified sequenced MiSeq platform. Rickettsia, Ehrlichia,...
Enterocytozoon bieneusi, which has recently been re-classified as a fungus, was identified in 5.2% (3/58) bat intestinal tissues and 1.9% (4/210) feces collected South Korea. The positive cases were classified into six genotypes including four novel genotypes, KBAT1-KBAT4, based on sequence analysis of the E. bieneusi internal transcribed spacer (ITS) region. In addition, genotype, KBAT3, belonged to group 1, is considered having zoonotic potential by phylogenetic ITS This study expands our...
