Steam treatment has been of practical interest, but information is needed on whether such treatment is able to inactivate the causative agent, Mycobacterium bovis. This study was to evaluate the use of pressurized steam for inactivation of Mycobacterium terrae, a surrogate for M. bovis on various surfaces.Methods: Carrier disks made of steel, wood, or rubber were inoculated with 6.32 ± 0.38 log10 M. terrae. While being held at background temperatures of -20°C, 4°C, or 21°C, these carrier disks were treated with pressurized steam (120°C ± 5°C) for 5, 10, 15, or 20 s. Reduction in colony forming units of M. terrae and temperatures on the top and bottom surfaces of the disks were determined.Results: Complete inactivation of 6 log10 M. terrae on steel and wood disks was achieved by 10 s of steam treatment at all three background temperatures. In comparison, 20 s of steam treatment was needed for the complete inactivation of mycobacteria on rubber disks. Corresponding to the longer treatment time required for mycobacterial inactivation, temperatures on the bottom surface of the rubber disks rose substantially slower than those of the steel and wood disks at all three background temperatures.Conclusion: The results suggested that treatment with pressurized steam has potential for efficient and effective disinfection of surfaces contaminated by mycobacteria at or below freezing temperatures in winter.","PeriodicalId":7962,"journal":{"name":"Applied Biosafety","volume":"28 3","pages":"192-198"},"PeriodicalIF":0.5,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10517315/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41102618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The principles of the downgrading process are based on the robust contamination controls in clinical and commercial manufacturing, which typically are not part of Research and Development processes. These strict requirements along with the application of current Good Manufacturing Practice (cGMP) principles provide a framework by which processes can be suitably managed and controlled to mitigate biohazard risk, specifically for cell lines that may be contaminated with human pathogenic viral agents.Purpose: We demonstrate how a risk assessment guide was used to define the risk profile of a theoretical process with a human cell line intended for clinical/commercial application. Based on the risk assessment, key BL2 elements were identified as suitable for downgrading, including facility containment controls, emergency spill response plans, and storage and shipping requirements. For various reasons, some aspects of the systems were deemed unsuitable for downgrading due to the severity of the control risk and, therefore, remained at BL2.Summary and conclusions: We have used an established risk assessment guide to show how cGMP compliments and augments biosafety containment. We provide justification for downgrading from BL2 to BL1 for clinical and commercial cell and gene therapy manufacturing with human cell lines.","PeriodicalId":7962,"journal":{"name":"Applied Biosafety","volume":"28 3","pages":"164-175"},"PeriodicalIF":0.5,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10510678/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41097542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, limited data are available on how frequently splashes occur when opening them. These data would be valuable for biorisk management in the laboratory.Methods: The frequency of splashes from opening snap-cap tubes using four different methods was tested. The splash frequency for each method was measured on the benchtop surface and on the experimenter's gloves and smock, using a Glo Germ solution as a tracer.Results: Splashes occurred very frequently when opening microcentrifuge snap-cap tubes, no matter which method was used to open the tube. The highest rate of splashes on all surfaces was observed with the one-handed (OH) opening method compared with two-handed methods. Across all methods, the highest rate of splashes was observed on the opener's gloves (70-97%) compared with the benchtop (2-40%) or the body of the researcher (0-7%).Conclusions: All tube opening methods we studied frequently caused splashes, with the OH method being the most error-prone but no two-handed method being clearly superior to any other. In addition to posing an exposure risk to laboratory personnel, experimental repeatability may be affected due to loss of volume when using snap-cap tubes. The rate of splashes underscores the importance of secondary containment, personal protective equipment, and good protocols for decontamination. When working with especially hazardous materials, alternatives to snap-cap tubes (such as screw cap tubes) should be strongly considered. Future studies can examine other methods of opening snap-cap tubes to determine whether a truly safe method exists.","PeriodicalId":7962,"journal":{"name":"Applied Biosafety","volume":"28 2","pages":"123-129"},"PeriodicalIF":1.5,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10278008/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9707697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Remaining viral RNA is used as such (naked replicon) or packaged into a viral replicon particle (VRP), whereby missing genes or proteins are supplied via production cells. Since replicons mostly originate from pathogenic wild-type viruses, careful risk consideration is crucial.Methods: A literature review was performed compiling information on potential biosafety risks of replicons originating from positive- and negative-sense single-stranded RNA viruses (except retroviruses).Results: For naked replicons, risk considerations included genome integration, persistence in host cells, generation of virus-like vesicles, and off-target effects. For VRP, the main risk consideration was formation of primary replication competent virus (RCV) as a result of recombination or complementation. To limit the risks, mostly measures aiming at reducing the likelihood of RCV formation have been described. Also, modifying viral proteins in such a way that they do not exhibit hazardous characteristics in the unlikely event of RCV formation has been reported.Discussion and conclusion: Despite multiple approaches developed to reduce the likelihood of RCV formation, scientific uncertainty remains on the actual contribution of the measures and on limitations to test their effectiveness. In contrast, even though effectiveness of each individual measure is unclear, using multiple measures on different aspects of the system may create a solid barrier. Risk considerations identified in the current study can also be used to support risk group assignment of replicon constructs based on a purely synthetic design.","PeriodicalId":7962,"journal":{"name":"Applied Biosafety","volume":"28 2","pages":"102-122"},"PeriodicalIF":1.5,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10278005/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10086654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
