Bacterial delivery vehicles comprising tracer nucleic acid sequences

Abstract

The present disclosure relates generally to genetically tagged bacterial delivery vehicles comprising unique tracer nucleic acid sequences (herein referred to as “tracers”) for use in detecting and/or quantitating the presence of two or more different said bacterial delivery vehicles within a mixture of vehicles. The present disclosure relates to methods wherein the bacterial delivery vehicles are detected through, for example, performance of multiple cycles of amplification using primers that bind to sequences within the unique tracer. Such methods can be advantageously used in quality control to detect and quantitate mixtures of bacterial delivery vehicles within a pharmaceutical composition.
