In addition, this field of science studies various clinical ...
Infection prevention and control. Infection prevention and control is the discipline concerned with preventing healthcare-associated infections; a practical rather than academic sub-discipline of epidemiology. In Northern Europe, infection prevention and control is expanded from healthcare into a component in public health, known as "infection ...

His most important contribution, however, was recognising that putrefaction in wounds is caused by germs, in connection to Louis Pasteur's then-novel germ theory of fermentation. [ a ] [ 6 ] Lister's work led to a reduction in post-operative infections and made surgery safer for patients, leading to him being distinguished as the "father of ...
The idea of a link between parasite infection and immune disorders was first suggested in 1968 [13] before the advent of large scale DNA sequencing techniques.The original formulation of the hygiene hypothesis dates from 1989, when David Strachan proposed that lower incidence of infection in early childhood could be an explanation for the rise in allergic diseases such as asthma and hay fever ...
Microbiology (from Ancient Greek μῑκρος (mīkros) 'small' βίος (bíos) ' life ' and -λογία (-logía) 'study of') is the scientific study of microorganisms, those being of unicellular (single-celled), multicellular (consisting of complex cells), or acellular (lacking cells).

Microorganisms growing on an agar plate. Sterilization (British English: sterilisation) refers to any process that removes, kills, or deactivates all forms of life (particularly microorganisms such as fungi, bacteria, spores, and unicellular eukaryotic organisms) and other biological agents (such as prions or viruses) present in or on a specific surface, object, or fluid.
