This list of laboratory biosecurity incidents includes accidental laboratory-acquired infections and laboratory releases of lethal pathogens, containment failures in or during transport of lethal pathogens, and incidents of exposure of lethal pathogens to laboratory personnel, improper disposal of contaminated waste, and/or the escape of laboratory animals.
Unsolved problems relating to the structure and function of non-human organs, processes and biomolecules include: Korarchaeota (archaea). The metabolic processes of this phylum of archaea are so far unclear. Glycogen body. The function of this structure in the spinal cord of birds is not known. Arthropod head problem. A long-standing zoological ...
Prior to 1950, few reports were made on laboratory-acquired infections, due to the lower level of awareness concerning the problem. In 1951, a paper from Sulkin and Pike presented data on viral infections contracted in laboratories, which advised caution on handling viruses in laboratory environments and brought public awareness to the issue.
Microbial cultures on solid and liquid media. A microbiological culture, or microbial culture, is a method of multiplying microbial organisms by letting them reproduce in predetermined culture medium under controlled laboratory conditions.
One use of the concept of biocontainment is related to laboratory biosafety and pertains to microbiology laboratories in which the physical containment of pathogenic organisms or agents (bacteria, viruses, and toxins) is required, usually by isolation in environmentally and biologically secure cabinets or rooms, to prevent accidental infection ...

Examining colonial morphology is the first step in the identification of an unknown microbe. The systematic assessment of the colonies' appearance, focusing on aspects like size, shape, colour, opacity, and consistency, provides clues to the identity of the organism, allowing microbiologists to select appropriate tests to provide a definitive ...
For example, you could pour some popcorn into a bowl instead of bringing the whole bag to the sofa. You could also buy single-serve bags of chips instead of family-size bags. nortonrsx/istockphoto
