Definition of Latin terms used in this paper for the detection of NETs in viable or fixed samples and individuals.

Latin term	Translation	Definition used in this review	Examples
In vivo	Within the living organism	Effects analyzed on whole, living organisms	Detection of NETs in a living animal after an infection with bacteria
In situ	In the natural, correct position	Effects analyzed on whole or partial organisms that are dead	Detection of NETs in histological samples derived from infected animals
Ex vivo	Out of the living organism	Effects analyzed on live isolated cells or biopsies with a minimum of changes of the natural conditions (tissue or body fluid)	Detection of NETs in body fluids (cytospin) or in tissue without fixation directly after isolation from viable organism
In vitro	In a test tube	Effects tested under laboratory conditions in test tubes, for example, Petri dishes	Detection of NET formation in response to pathogens or chemicals by purified blood-derived neutrophils in tissue culture plates
Intravital	Occurring during life	Visualization of an event in the living organisms by microscopy, same as in vivo	See in vivo
