Alternative career paths are also highlighted, opening first with hospital departments adjacent to the clinical microbiology laboratory, such as quality assurance and infection prevention and control. In addition, careers in public health laboratories, research laboratories, scientific communication, project management, government, and the food industry, as well as foundation and non-profit work, are highlighted. Various technical career pathways within the industry and biotechnology sectors are described. The review concludes by acknowledging that for some individuals, career goals may not be fully realized without the pursuit of higher education, and it provides some overarching career advice for taking the next step toward a new career pathway.</p></div>","PeriodicalId":39211,"journal":{"name":"Clinical Microbiology Newsletter","volume":"45 7","pages":"Pages 55-60"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44228918","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While many self-collection devices were evaluated for collection of specimens for SARS-CoV-2 testing, they can be used to collect samples for many other serologic, molecular, or other diagnostic methods following completion of necessary laboratory validation studies.

Current microbiological methods include culture, serology, and limited molecular panels. While helpful, these methods are unable to address the full range of potential pathogens (e.g., fastidious or noncultivable organisms or uncommon organisms not included in current panels). Metagenomic next-generation sequencing (mNGS) is a molecular technique that analyzes and compares the nucleic acid content in a patient sample to a reference database of organisms that may include bacteria, viruses, fungi, and/or parasites, depending on the mNGS technology used. By bypassing the limitations of culture and targeted molecular assays, mNGS offers the potential to identify countless organisms directly from a patient specimen to aid in the diagnosis of an infectious process. Although promising, mNGS does have considerable limitations related to cost, interpretation, standardization, clinical relevance, turnaround time (TAT), and widespread availability. Thus, these factors should be considered prior to implementing mNGS for clinical use. Moreover, additional studies are required to fully understand the clinical and epidemiological impact of mNGS for the diagnosis of infectious diseases, including respiratory infections.</p></div>","PeriodicalId":39211,"journal":{"name":"Clinical Microbiology Newsletter","volume":"45 3","pages":"Pages 19-27"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46966228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
