For these antibacterial drugs, drug susceptibility has been correlated with clinical response in MAC diseases. We have previously demonstrated the correlation between drug susceptibility and mutations in the 23S rRNA gene, which confers resistance to macrolides. Herein, we developed a rapid detection method using the amplification refractory mutation system (ARMS)\u2013loop-mediated isothermal amplification (LAMP) technique to identify mutations in the 23S rRNA gene of\n              <jats:italic>M. avium<\/jats:italic>\n              . We examined the applicability of the ARMS\u2013LAMP method to genomic DNA extracted from six genotypes of\n              <jats:italic>M. avium<\/jats:italic>\n              clinical isolates. The\n              <jats:italic>M. avium<\/jats:italic>\n              isolates were classified into 21 CLR-resistant and 9 CLR-susceptible strains based on the results of drug susceptibility tests; the 23S rRNA genes of these strains were sequenced and analyzed using the ARMS\u2013LAMP method. Sequence analysis revealed that the 9 CLR-sensitive strains were wild-type strains, whereas the 21 CLR-resistant strains comprised 20 mutant-type strains and one wild-type strain. Using ARMS\u2013LAMP, no amplification from genomic DNAs of the 10 wild-type strains was observed using the mutant-type mismatch primer sets (MTPSs); however, amplification from the 20 mutant-type strain DNAs was observed using the MTPSs. The rapid detection method developed by us integrates ARMS\u2013LAMP with a real-time turbidimeter, which can help determine drug resistance in a few hours. In conclusion, ARMS\u2013LAMP might be a new clinically beneficial technology for rapid detection of mutations.\n            <\/jats:p>\n            <jats:sec>\n              <jats:title>IMPORTANCE<\/jats:title>\n              <jats:p>\n                Multidrug therapy for pulmonary\n                <jats:italic>Mycobacterium avium<\/jats:italic>\n                complex disease is centered on the macrolide antibiotics clarithromycin and azithromycin, and resistance to macrolides is an important prognosticator for clinical aggravation. Therefore, it is important to develop a quick and easy method for detecting resistance to macrolides. Drug resistance is known to be correlated with mutations in macrolide resistance genes. We developed a rapid detection method using amplification refractory mutation system (ARMS)\u2013loop-mediated isothermal amplification (LAMP) to identify a mutation in the 23S rRNA gene, which is a macrolide resistance gene. Furthermore, we examined the applicability of this method using\n                <jats:italic>M. avium<\/jats:italic>\n                clinical isolates. The rapid method developed by us for detection of the macrolide resistance gene by integrating ARMS\u2013LAMP and a real-time turbidimeter can help in detection of drug resistance within a few hours. Since this method does not require expensive equipment or special techniques and shows high analytical speed, it would be very useful in clinical practice.\n              <\/jats:p>\n            <\/jats:sec>\n          <\/jats:sec>","DOI":"10.1128\/spectrum.02339-23","type":"journal-article","created":{"date-parts":[[2024,2,16]],"date-time":"2024-02-16T13:36:47Z","timestamp":1708090607000},"update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":3,"title":["Development of a rapid detection method for the macrolide resistance gene in\n            <i>Mycobacterium avium<\/i>\n            using the amplification refractory mutation system\u2013loop-mediated isothermal amplification method"],"prefix":"10.1128","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-9147-556X","authenticated-orcid":false,"given":"Takayuki","family":"Inagaki","sequence":"first","affiliation":[{"name":"Division of Pharmaceutical Sciences I, Faculty of Pharmacy, Meijo University, Nagoya, Aichi, Japan"},{"name":"Department of Hospital Pharmacy, Nagoya University Hospital, Nagoya, Aichi, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shoki","family":"Asahi","sequence":"additional","affiliation":[{"name":"Department of Hospital Pharmacy, Japan Organization of Occupational Health and Safety, Chubu Rosai Hospital, Nagoya, Aichi, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenji","family":"Ogawa","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine, National Hospital Organization, Higashinagoya National Hospital, Nagoya, Aichi, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Taku","family":"Nakagawa","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine, National Hospital Organization, Higashinagoya National Hospital, Nagoya, Aichi, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Teruko","family":"Ohkura","sequence":"additional","affiliation":[{"name":"Department of Medical Technique, Nagoya University Hospital, Nagoya, Aichi, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yukari","family":"Osada","sequence":"additional","affiliation":[{"name":"Department of Medical Technique, Nagoya University Hospital, Nagoya, Aichi, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshiaki","family":"Nikai","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Faculty of Pharmacy, Meijo University, Nagoya, Aichi, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kiyofumi","family":"Yamada","sequence":"additional","affiliation":[{"name":"Department of Neuropsychopharmacology and Hospital Pharmacy, Nagoya University Graduate School of Medicine, Nagoya, Aichi, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tetsuya","family":"Yagi","sequence":"additional","affiliation":[{"name":"Department of Infectious Diseases, Nagoya University Graduate School of Medicine, Nagoya, Aichi, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9337-6354","authenticated-orcid":true,"given":"Kei-ichi","family":"Uchiya","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Faculty of Pharmacy, Meijo University, Nagoya, Aichi, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.200604-571ST"},{"key":"e_1_3_4_3_2","first-page":"83","article-title":"Opinions on chemotherapy of non-tuberculous acid-fast bacterial infection of the lung","volume":"87","author":"Committee on Management of Non-Tuberculous Acid-Fast Bacterial Infection, Japanese Society of Tuberculosis; Infection and Tuberculosis Section of Japanese Society of Respiratory Diseases","year":"2012","unstructured":"Committee on Management of Non-Tuberculous Acid-Fast Bacterial Infection, Japanese Society of Tuberculosis; Infection and Tuberculosis Section of Japanese Society of Respiratory Diseases. 2012.
