WebOct 15, 2014 · Investigating genome reduction of Bordetella pertussis using a multiplex PCR-based reverse line blot assay (mPCR/RLB) The mPCR/RLB assay offers an inexpensive and fast method of determining the gene content of B. pertussis strains and also confirms that gene losses are an ongoing feature of B. pertussis evolution. WebApr 4, 2024 · Abstract Bacteria that form long-term intracellular associations with host cells lose many genes, a process that often results in tiny, gene-dense, and stable genomes. Paradoxically, the same evolutionary processes that drive genome reduction and simplification may also sometimes cause genome expansion and complexification.
