The JSC Microbiology team addresses the benefits and risks related to microorganisms, including infectious disease, allergens, environmental and food contamination, and the impacts of changes in environmental and human microbial ecology aboard spacecraft. The team includes certified medical technologists, environmental microbiologists, mycologists, and biosafety professionals.<\/p>\n\n\n\n<p>The JSC Microbiology laboratory, a Biosafety Level 2 facility, is a critical component of the Human Health and Performance Directorate and is responsible for addressing crew health and environmental issues related to microbial infection, allergens, and contamination. This responsibility is achieved by operational monitoring and investigative research using classical microbiological, advanced molecular, and immunohistochemical techniques. This research has resulted in a significant number of presentations and peer-reviewed publications contributing to the field of Microbiology with articles in journals such as Infection and Immunity, Journal of Infectious Disease and Applied and Environmental Microbiology, Nature Reviews Microbiology, and Proceedings of the National Academies of Science.<\/p>\n\n\n<div id=\"\" class=\"nasa-gb-align-center padding-y-3 maxw-full width-full display-flex flex-align-center hds-module wp-block-nasa-blocks-blockquote\"><div class=\"grid-container grid-container-block display-flex flex-column flex-justify-center padding-0\">\n\t\t<div class=\"grid-col-12 desktop:display-flex mobile:display-block\">\n\t\t\t<div class=\"blockquote-icon margin-bottom-3\">\n\t\t\t\t<svg class=\"tablet:square-4 square-4 margin-right-3\" version=\"1.1\" aria-hidden=\"true\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" x=\"0px\" y=\"0px\" viewBox=\"0 0 3000 3000\" style=\"enable-background:new 0 0 3000 3000;\" xml:space=\"preserve\"> <g> <path d=\"M586.7,1429.7c-10.7,1.5-21.4,2.8-33.9,4.5c6.9-26.6,12.7-50.7,19.5-74.6c32.4-114.1,78.5-222.2,146.8-319.5 c90.2-128.5,202.5-235.3,327.7-329.1c8.4-6.3,16.7-12.6,25.3-19.1c-66.3-105.1-131.5-208.6-197.3-313.1c-3.5,1.2-5.5,1.6-7.2,2.6 C714.4,469,576.1,575.7,456,705.3c-126,135.9-226.2,289.1-303,457.8c-98.8,217.1-151.3,444-147.2,683.3 c1.7,100.5,12.9,199.6,41.1,296.3C93.7,2303,182.2,2433,326.7,2520.1c176.9,106.7,366.8,126.8,563.4,70.5 c150.9-43.2,260.9-138.9,327.2-282.5c33.4-72.5,47.8-149.4,52-228.7c6.5-122.8-14.1-239.5-74.3-348.1 C1074.6,1514.5,832.7,1394.2,586.7,1429.7z\"><\/path><path d=\"M2912.5,1722c-129.9-210.9-320.2-309.4-567.9-296c-22.1,1.2-44,5.1-67.4,7.9c2.2-9.6,4-17.9,6.1-26.2 c37.9-153.6,99.3-296,198.8-420.5c77.8-97.4,167.1-182.9,265.8-258.8c15.6-12,31.3-23.9,47.9-36.5 c-66.2-105.1-131.9-209.2-197.2-312.8c-3.5,1.1-5.1,1.2-6.4,2c-167.2,95.6-316.1,213.7-443.2,358.8 c-105.1,119.9-191.1,252.3-259.5,396.3c-95.5,201-152.1,411.6-159.1,634.8c-3.9,125.5,4.8,249.7,40.1,371 c46.7,160.8,135.7,290.9,280.5,378.7c165.7,100.5,344.8,123,531.2,78.8c172.4-40.8,296.4-143.9,366.3-308.5 c28.5-67.2,40.6-138,44.6-210.5C3000.2,1953.3,2979.9,1831.4,2912.5,1722z\"><\/path><\/g><\/svg>\n\t\t\t<\/div>\n\t\t\t<div class=\"blockquote-content\">\n\t\t\t\t<div class=\"margin-bottom-4\">\n\t\t\t\t\t<h2 class=\"font-weight-extralight line-height-sm margin-top-0 section-heading-sm\"><span class=\"section-heading-sm\">Fun Fact: Microorganisms display unexpected responses when grown in the spaceflight environment compared to otherwise identically grown microbes on Earth.<\/span><\/h2>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"display-flex\">\n\t\t\t\t\t<div class=\"blockquote-image hds-cover-wrapper margin-right-3\"><figure class=\"hds-media-background  \"><img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/07\/cropped-581097main_STS-1_Dust-it-Off-mp3-image.gif?w=150&h=150&crop=1\" class=\"attachment-thumbnail size-thumbnail\" alt=\"NASA\" style=\"transform: scale(1);

The BRB includes a team of microbiologists, cell biologists, physicians, industrial hygienists, and occupational health professionals to assess the wide range of biohazardous materials encountered. Biohazardous materials may consist of bacteria, fungi, viruses, protozoa, cell cultures, and other infectious agents. All biological payloads are assessed, and biohazardous materials identified are assigned a NASA biosafety level. Additional functions of the BRB include evaluating ground-based experiments using biohazardous materials, maintaining a current inventory of biohazardous materials stored at JSC facilities, and conducting an annual inspection of JSC facilities using biohazardous materials.<\/p>\n\n\n\n<p>For more information, contact <a
