Afb Isolation Rapid Culture Sputum

Definition. Isolation refers to the precautions that are taken in the hospital to prevent the spread of an infectious agent from an infected or colonized patient to susceptible persons. There are many ways to do this, but one of the most often used is the method of pseudo-first order conditions. This method is sometimes also referred to as the method of isolation or the method of flooding. A microbiological culture, or microbial culture, is a method of multiplying microbial organisms by letting them reproduce in predetermined culture media under controlled laboratory conditions. Microbial cultures are used to determine the type of organism, its abundance in the sample being tested, or both. Recommendations for isolating potentially infectious tuberculosis (TB) patients differ depending on sputum smear results; level of clinical suspicion; drug sensitivity of the organism; type of setting; and the age, immune status and exposure status of household members. Tuberculosis is a chronic, granulomatous disease caused by M. tuberculosis. Identification, and, if appropriate, antibiotic sensitivity, is required to initiate necessary therapy.
