Data Availability StatementThe datasets analysed during the current study are available at National Center for Biotechnology Information (NCBI) repository, (accession numbers; “type”:”entrez-nucleotide”,”attrs”:”text”:”KU519285″,”term_id”:”1009021919″,”term_text”:”KU519285″KU519285, “type”:”entrez-nucleotide”,”attrs”:”text”:”KU519286″,”term_id”:”1009021921″,”term_text”:”KU519286″KU519286, “type”:”entrez-nucleotide”,”attrs”:”text”:”KU519287″,”term_id”:”1009021923″,”term_text”:”KU519287″KU519287, “type”:”entrez-nucleotide”,”attrs”:”text”:”JQ622144″,”term_id”:”385282656″,”term_text”:”JQ622144″JQ622144, “type”:”entrez-nucleotide”,”attrs”:”text”:”KJ677106″,”term_id”:”677570380″,”term_text”:”KJ677106″KJ677106 and “type”:”entrez-nucleotide”,”attrs”:”text”:”KT986059″,”term_id”:”1004642887″,”term_text”:”KT986059″KT986059). to the Chosun University Hospital, Korea, outpatient clinic on June 19, 2018, for a second opinion. The patient was not sure of when she had been bitten by the tick. On the basis of her statement, that she had worked in fields 10C15?days prior to the medical center go to, we suspected the fact that tick have been on her behalf for ~?10?times. Through the physical evaluation, a tick was found by us bite site on the low component of her best clavicle. However the tick was removed after it had been taken out, she brought an image from the tick following the removal (Fig.?1). Open up in another home window Fig. 1 The tick picture captured using the sufferers cellular phone (a). The tick bite lesion located under the right clavicle (b) Although we could not accurately classify the tick morphologically or genetically, it was highly likely a nymph of either spp. or spp., which are common in Korea. All the laboratory test results were within reference ranges: the first blood test results revealed a white blood cell (WBC) count of 5.1??103/L, hemoglobin of 13.8?g/dL, and a platelet count of 2.47??105/L; the blood biochemical test results showed aspartate aminotransferase (AST) at 17.9?U/L, alanine aminotransferase (ALT) at 17.1?U/L, -glutamyltransferase Rictor at 21?U/L, total bilirubin at 0.48?mg/dL, alkaline phosphatase (ALP) at 56?U/L, glucose of 86?mg/dL, blood urea nitrogen of 13.3?mg/dL, creatinine at 0.66?mg/dL, cholesterol at 211?mg/dL, and triglycerides at 98?mg/dL. Although the patient was asymptomatic, we tested for tick-borne infectious diseases, e.g., anaplasmosis and rickettsiosis, by nested PCR (nPCR) LEQ506 and serological assays. nPCR After extracting genomic DNA from your patients blood sample using the QIAamp Tissue and Blood Mini Kit (Qiagen, Hilden, Germany), nPCR was conducted using (warmth shock protein chaperone) gene; primer pairs ANK-F1/ANK-R1 and ANK-F2/ANK-R2 [11], which target the (ankyrin-repeat protein) gene; and primer pairs AE1-F/AE1-R and AP-F/AP-R, which target the 16S ribosomal RNA (rRNA) gene [12]. To detect SFG rickettsiosis, nPCR was carried out using primer pairs sca1-6545F/sca1-7360R and sca1-6647F/sca1-7354R, which target the (rickettsial surface protein) gene, and primers RR190.70F, RR190.602R, and RR190.701R [13], which are specific to the gene. All primers that target the gene were designed after sequence alignment to amplify this genomic region of all spp. The PCR products were separated by electrophoresis on a 1.2% agarose gel. In each PCR run, the reaction combination without the template DNA served as a negative control. The genomic DNAs of KZ_A3 and were employed as positive controls for nPCR for Anaplasmataceae (external primers) GRO607F (GAAGATGCWGTWGGWTGTACKGC) GRO1294R (AGMGCTTCWCCTTCWACRTCYTC) 539nPCR for Anaplasmataceae (internal primers) GRO677F (ATTACTCAGAGTGCTTCTCARTG) GRO1121R (TGCATACCRTCAGTYTTTTCAAC) 45016S rRNA nPCR for and species (external primers)AE1-F (AAGCTTAACACATGCAAGTCGAA) AE1-R (AGTCACTGA CCCAACCTTAAATG) 140616S rRNA nPCR for nPCR for nPCR LEQ506 for nPCR for SFG (external primers) sca1-6545F (ATTCGTAACAGATTAGATRC) sca1-7360R (TTATAGGATGTTTTCGGTTG) 815nPCR for SFG (internal primers)sca1-6647F (TGGATGCGTGSTATGTACG) sca1-7354R (GATGTTTTCGGTTGYTTCGG) 707nPCR for SFG (external primers)R190.70F (ATGGCGAATATTTCTCCAAAAA) RR190.701R (GTTCCGTTAATGGCAGCATCT) 634nPCR for SFG (internal primers)R190.70F (ATGGCGAATATTTCTCCAAAAA) RR190.602R (AGTGCAGCATTCGCTCCCCCT) 535 Open in a separate window aankyrin-repeat protein gene, heat shock protein chaperone gene, ribosomal RNA, surface cell antigen 1 (rickettsial surface protein) gene, outer membrane protein A gene Serological screening An indirect immunofluorescence assay (IFA) was performed for the serological diagnosis of the patient. To detect antibodies to SFG strain. A four-fold or greater increase in the antibody titer in the acute-phase and convalescent-phase serum samples was LEQ506 assumed to be a positive indication of SFG rickettsiosis and anaplasmosis [1]. The nPCR that was performed around the patients first visit (June 19) yielded a positive result around the and genes; however, the nPCR targeting the 16S rRNA gene gave a negative result. DNA sequencing of the positive-result PCR products from the individual showed the fact that gene series was a 100% match (332 out of 332?bp) for isolates S-DD-21, D-SE-63, D-GB-39, and lp11C2 (GenBank accession quantities “type”:”entrez-nucleotide”,”attrs”:”text”:”KU519285″,”term_id”:”1009021919″,”term_text”:”KU519285″KU519285, “type”:”entrez-nucleotide”,”attrs”:”text”:”KU519286″,”term_id”:”1009021921″,”term_text”:”KU519286″KU519286, “type”:”entrez-nucleotide”,”attrs”:”text”:”KU519287″,”term_id”:”1009021923″,”term_text”:”KU519287″KU519287, and “type”:”entrez-nucleotide”,”attrs”:”text”:”JQ622144″,”term_id”:”385282656″,”term_text”:”JQ622144″JQ622144, respectively). Genotype S-DD-21, D-SE-63, and D-GB-39 had been discovered in Korean dogs and cats originally, and isolate lp11C2 hails from a Japanese tick. Isolate gw1, that was gathered from a Korean individual originally, acquired the second-highest homology with this stress, and phylogenetic-tree evaluation showed our strain is one of the same group as (Fig.?2a).
