In microbiology, the term isolation refers to the separation of a strain from a natural, mixed population of living microbes, as present in the environment, for example in water or soil, or from living beings with skin flora, oral flora or gut flora, in order to identify the microbe(s) of interest.

In microbiology, streaking is a technique used to isolate a pure strain from a single species of microorganism, often bacteria. Samples can then be taken from the resulting colonies and a microbiological culture can be grown on a new plate so that the organism can be identified, studied, or tested.
An inoculation loop (also called a smear loop, inoculation wand or microstreaker) is a simple tool used mainly by microbiologists to pick up and transfer a small sample of microorganisms called inoculum from a microbial culture, e.g. for streaking on a culture plate.
Medical aseptic techniques also includes curbing the spread of infectious diseases through quarantine, specifically isolation procedures based on the mode of disease transmission. [12] Within contact, droplet and airborne isolation methods, two different procedures emerge: strict isolation vs. reverse isolation. [12]
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 ...
Bile esculin agar is used for the isolation of Enterococcus and group D Streptococcus species. CLED agar – cysteine, lactose, electrolyte-deficient agar is used to isolate and differentiate urinary tract bacteria, since it inhibits Proteus species swarming and can distinguish between lactose fermenters and nonfermenters.
A close up of an inoculation needle. An inoculation needle is a laboratory equipment used in the field of microbiology to transfer and inoculate living microorganisms. [1] [full citation needed] It is one of the most commonly implicated biological laboratory tools and can be disposable or re-usable. [1]
