All adjusted models in multivariate analysis showed that these variables were the presence of agrIV type and sed gene for colonizing strains; the presence of sea, undisrupted hlb and isaB genes for CRB; sed, splE and fib genes for an endocarditis source; undisrupted hlb for the SSTI group; and finally, CC5, msrA resistance gene and hla gene with respect to bacteremia from an osteoarticular source (Table 5). The gene discussed is FBL; the disease is bacterial infectious disease with sepsis.
