This pathogen is well known for its multidrug resistance and possible bioweapon potential. There is currently no report of the pathogen from clinical specimens in Nigeria, which might be due to misdiagnosis with phenotypic assays. This study aims to explore the accuracy of the use of phenotypic assays to diagnose\n \n \n B. pseudomallei<\/jats:ext-link>\n <\/jats:named-content>\n <\/jats:italic>\n in Nigeria. Two hundred and seventeen clinical samples and 28 Gram-negative clinical isolates were collected and analysed using Ashdown\u2019s selective agar and monoclonal antibody-based latex agglutination. Species-level identification was achieved using the analytical profile index (API) 20NE system. The susceptibility of the isolates to nine different antimicrobial agents was determined using the disc diffusion method. A total of seventy-four culture-positive isolates were obtained using Ashdown\u2019s selective agar. Twenty-two of these isolates were believed to be\n \n \n B. pseudomallei<\/jats:ext-link>\n <\/jats:named-content>\n <\/jats:italic>\n through the monoclonal antibody-based latex agglutination test and the API 20NE system subsequently identified 14 isolates as\n \n \n Burkholderia<\/jats:ext-link>\n <\/jats:named-content>\n <\/jats:italic>\n . The predominant\n \n \n Burkholderia<\/jats:ext-link>\n <\/jats:named-content>\n <\/jats:italic>\n species was\n \n \n B. cepacia<\/jats:ext-link>\n <\/jats:named-content>\n <\/jats:italic>\n with an isolation rate of 30.8\u200a% (8\/26). No isolate was distinctively identified as\n \n \n B. pseudomallei<\/jats:ext-link>\n <\/jats:named-content>\n <\/jats:italic>\n but five isolates were strongly suspected to be\n \n \n B. pseudomallei<\/jats:ext-link>\n <\/jats:named-content>\n <\/jats:italic>\n with similarity indices ranging from 81.9\u201391.3\u200a%. Other bacterial species with definitive identity include\n \n \n Aeromonas<\/jats:ext-link>\n <\/jats:named-content>\n <\/jats:italic>\n sp.,\n \n \n Sphingomonas<\/jats:ext-link>\n <\/jats:named-content>\n <\/jats:italic>\n sp. and\n \n \n Pseudomonas aeruginosa<\/jats:ext-link>\n <\/jats:named-content>\n <\/jats:italic>\n . The antibiotic susceptibility results revealed an overall resistance to amoxicillin\u2013clavullanic acid of 71.4\u200a%, to cefepime of 33.3\u200a%, to trimethoprim\u2013sulfamethoxazole of 38.1\u200a%, to piperacillin\u2013tazobactam of 33.3\u200a%, to imipenem of 66.7\u200a%, to doxycycline of 57.1% and to ceftazidime of 66.7\u200a%. The highest intermediate resistance was observed for cefepime and piperacillin\u2013tazobactam with a value of 66.7\u200a% each, while there was no intermediate resistance for gentamicin, colistin and imipenem. Our findings, therefore, show that phenotypic assays alone are not sufficient in the diagnosis of melioidosis. Additionally, they provide robust support for present and future decisions to expand diagnostic capability for melioidosis beyond phenotypic assays in low-resource settings.\n <\/jats:p>","DOI":"10.1099\/acmi.0.000604.v5","type":"journal-article","created":{"date-parts":[[2023,10,18]],"date-time":"2023-10-18T12:17:13Z","timestamp":1697631433000},"source":"Crossref","is-referenced-by-count":2,"title":["Showing the limitations of available phenotypic assays to detect Burkholderia pseudomallei from clinical specimens in Nigeria"],"prefix":"10.1099","volume":"5","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8905-9927","authenticated-orcid":false,"given":"Oluwatosin Qawiyy","family":"Orababa","sequence":"first","affiliation":[{"name":"Department of Microbiology, Faculty of Science, University of Lagos, Akoka, Nigeria"},{"name":"Present address: School of Life Sciences, Gibbet Hill campus, University of Warwick, Coventry, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Solayide A.","family":"Adesida","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Faculty of Science, University of Lagos, Akoka, Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rebecca F.","family":"Peters","sequence":"additional","affiliation":[{"name":"Department of Medical Microbiology and Parasitology, Lagos University Teaching Hospital, Idi-Araba, Lagos, Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zainab","family":"AbdulGanniyu","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Faculty of Science, University of Lagos, Akoka, Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Olawale","family":"Olakojo","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Faculty of Science, University of Lagos, Akoka, Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adefunke","family":"Abioye","sequence":"additional","affiliation":[{"name":"Lagos State Biobank, Mainland Hospital, Yaba, Lagos, Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"345","reference":[{"key":"R1","doi-asserted-by":"publisher","DOI":"10.12688\/f1000research.8221.1"},{"key":"R2","doi-asserted-by":"publisher","DOI":"10.1007\/s10295-020-02317-0"},{"key":"R3","doi-asserted-by":"publisher","DOI":"10.1128\/JB.00997-13"},{"key":"R4","doi-asserted-by":"publisher","DOI":"10.3390\/metabo11050321"},{"key":"R5","doi-asserted-by":"publisher","DOI":"10.1128\/AEM.00128-14"},{"key":"R6","doi-asserted-by":"publisher","DOI":"10.3389\/fmicb.2022.902996"},{"key":"R7","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-030-03071-1"},{"key":"R8","doi-asserted-by":"publisher","DOI":"10.3390\/ijerph192315475"},{"key":"R9","doi-asserted-by":"publisher","DOI":"10.3201\/eid0802.010164"},{"key":"R10","article-title":"Bioterrorism","year":"2021"},{"key":"R11","doi-asserted-by":"publisher","DOI":"10.4103\/0972-1282.116094"},{"key":"R12","doi-asserted-by":"publisher","DOI":"10.1016\/S0035-9203(08)70002-6"},{"key":"R13","doi-asserted-by":"publisher","DOI":"10.3201\/eid1906.120717"},{"key":"R14","doi-asserted-by":"publisher","DOI":"10.1038\/nmicrobiol.2015.8"},{"key":"R15","doi-asserted-by":"publisher","DOI":"10.3201\/eid1707.110502"},{"key":"R16","doi-asserted-by":"publisher","DOI":"10.19182\/remvt.31642"},{"key":"R17","doi-asserted-by":"publisher","DOI":"10.3201\/eid2905.221138"},{"key":"R18","doi-asserted-by":"publisher","DOI":"10.1128\/JCM.43.10.5359-5361.2005"},{"key":"R19","doi-asserted-by":"publisher","DOI":"10.1128\/9781555816728"},{"key":"R20","doi-asserted-by":"publisher","DOI":"10.1080\/00313029800169685"},{"key":"R21","doi-asserted-by":"publisher","DOI":"10.1513\/AnnalsATS.201906-443OC"},{"key":"R22","doi-asserted-by":"publisher","DOI":"10.3201\/eid2802.210945"},{"key":"R23","doi-asserted-by":"publisher","DOI":"10.1016\/j.cmi.2020.11.012"},{"key":"R24","doi-asserted-by":"publisher","DOI":"10.1186\/s13104-017-2626-5"},{"key":"R25","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.02230-20"},{"key":"R26","article-title":"The European Committee on Antimicrobial Susceptibility Testing.
