There are not many reports of "S. quinivoran" causing infection in humans. A homeless man in France was admitted to the hospital with a mouth abscess. The man developed pneumonia and respiratory issues. "S. quinivoran" was recovered from a sample and was later identified as the cause of his organ failure and death. "S. rubidaea, S. odorifera," and "S. plymuthica" are other "Serratia" species that are human pathogens. However, not all "Serratia" species are human pathogens. "S. entomophia" and "S. proteamaculans" are insect and plant pathogens.
