Biological hazard symbol design: A red on white or white-coloured background is used behind a black biohazard symbol when integrated with a DANGER sign, label or paragraph. An orange on black or white-coloured background is used behind a black biohazard symbol when integrated with a WARNING sign, label or paragraph.
The black rat is a reservoir host for bubonic plague. The rat fleas that infest the rats are vectors for the disease. In biology and medicine, a host is a larger organism that harbours a smaller organism; [1] whether a parasitic, a mutualistic, or a commensalist guest . The guest is typically provided with nourishment and shelter.
The reservoir contains the amount of material M under consideration, as defined by chemical, physical or biological properties. The source Q is the flux of material into the reservoir, and the sink S is the flux of material out of the reservoir. The budget is the check and balance of the sources and sinks affecting material turnover in a reservoir.
In supramolecular chemistry, [1] host–guest chemistry describes complexes that are composed of two or more molecules or ions that are held together in unique structural relationships by forces other than those of full covalent bonds. Host–guest chemistry encompasses the idea of molecular recognition and interactions through non-covalent ...
Cows are natural reservoirs of African trypanosomiasis. In infectious disease ecology and epidemiology, a natural reservoir, also known as a disease reservoir or a reservoir of infection, is the population of organisms or the specific environment in which an infectious pathogen naturally lives and reproduces, or upon which the pathogen primarily depends for its survival.
Host factor (sometimes known as risk factor) [1] is a medical term referring to the traits of an individual person or animal that affect susceptibility to disease, especially in comparison to other individuals. [2]
Biophysical organic chemistry is a term used when attempting to describe intimate details of molecular recognition by bioorganic chemistry. [ 3 ] Natural product chemistry is the process of Identifying compounds found in nature to determine their properties.
Integration host factor, IHF, is not a nucleoid-associated protein only found in gram negative bacteria. [15] It is a 20 kDa heterodimer, composed of α and β subunits that bind to the sequence 5' - WATCAANNNNTTR - 3' and bends the DNA approximately 160 degrees. [16] The β arms of IHF have Proline residues that help stabilize the DNA kinks.
