Figure 6

A proposed model for the dissemination and transmission of Staphylococcus saprophyticus in the community. The arrows represent the dissemination and transmission of S. saprophyticus isolates that belonged to lineage G (green) and lineage S (yellow). Lineage G S. saprophyticus strains are of animal origin and enter the slaughterhouse through production animals, such as pigs, persist on the equipment, and contaminate the meat in processing chain. Lineage G strains could enter the community through contaminated meat and workers colonized in the slaughterhouse. Lineage S strains most likely are of humans and primate origin and probably are disseminated by person-to-person contact within the community.
