Pathogenesis
S. marcescens can cause conjunctivitis, keratitis, endophthalmitis, and tear duct infections. It is common in the respiratory and urinary tracts of adults and the gastrointestinal system of children.[3] Most S. marcescens strains are resistant to several antibiotics because of the presence of R-factors, which are a type of plasmid that carry one or more genes that encode resistance.
In coral, S. marcescens is the cause of the disease known as White pox.[citation needed] In silkworms, it sometimes occurs as a secondary pathogen in viral flacherie disease.
