Transport media are basically buffer solutions that contain carbohydrate, peptones, along with other nutritional elements (excluding growing factors) that are designed to protect the health of bacteria during transport, without allowing for their multiplicity. The main goal of utilization of the medium is to keep the sample as close to its original condition as is possible.
Burkholderia cepacia can be viewed as an opportunity-based bacterium that is associated with nosocomial illnesses caused by contamination of medical equipment and disinfectants.
