Pneumoviridae (from Greek pneumo-'lung' + -viridae 'virus', from Latin, 'poison, slimy liquid') [2] is a family of negative-strand RNA viruses in the order Mononegavirales. [1] [3] Humans, cattle, and rodents serve as natural hosts. [4] Respiratory tract infections are associated with member viruses such as human respiratory syncytial virus.
Biosafety level 4 laboratories are designed for diagnostic work and research on easily respiratory-acquired viruses which can often cause severe and/or fatal disease. What follows is a list of select agents that have specific biocontainment requirements according to US federal law.
When control of plant virus infections is considered economical, for perennial fruits, for example, efforts are concentrated on killing the vectors and removing alternate hosts such as weeds. [13]: 802 Plant viruses cannot infect humans and other animals because they can reproduce only in living plant cells. [13]: 799–807
“While the overall risk of contracting a virus from frozen berries remains relatively low, the persistence of viruses like norovirus and hepatitis A in frozen conditions is concerning,” says ...
The study of viruses and virus-like agents, which seeks to understand and explain their structure, classification, evolution, and mechanisms of infection, as well as the diseases they cause, techniques to isolate and culture them, and their use in research and therapy. Virology is often considered a subfield of microbiology or of medical ...
RSV, respiratory syncytial virus, usually peaks in December and January while infecting the nose, throat and lungs, usually causing mild, cold-like symptoms, the CDC says. Those symptoms make it ...
It’s a common virus that causes illness in the upper and lower respiratory tracts, Dr. William Schaffner, a professor of infectious disease at the Vanderbilt University Medical Center, tells ...
A biofilm may also be considered a hydrogel, which is a complex polymer that contains many times its dry weight in water. Biofilms are not just bacterial slime layers but biological systems; the bacteria organize themselves into a coordinated functional community.
