摘要: The bacterial species have co-evolved with the human race and account for more than 3,000 distinct of which most are beneficial to humans. They a few micrometres in length outnumber eukaryotic cells by ratio 10,000:1. evolved their own strategies countering defences host. Pathogenicity microorganisms is through expression virulence factors, could be attributed genetic or biochemical structural features, responsible organism cause an infection host (Oelschlaeger et al. 2002). dynamic relationship between pathogen outcome resistance susceptibility invading (Casadevall Pirofski 2000).
