Sixty coagulase-negative staphylococcus (CNS) isolates were recovered from the blood cultures or peritoneal dialysate effluent of 43 @entity1 on renal dialysis. The @entity1 had either renal dialysis @entity1212 ( @entity1212 ) or continuous ambulatory peritoneal dialysis (CAPD)-associated @entity298 . Isolates were characterized by biotyping, and genotyped by pulsed-field gel electrophoresis (PFGE). Phenotypic properties of the strains were also investigated. Several genotypes were identified with no one specific strain of CNS being associated with @entity1212 . However, closely related strains were isolated from several @entity1 within the units studied, suggesting horizontal transfer of micro-organisms. Genotypic macro-restriction profiles did not concur with phenotypic profiles or biotypes, confirming that genotyping is required for epidemiological studies. All staphylococcal strains were investigated for the production of phenotypic characteristics. Significant differences were predominantly seen in the production of lipase, esterase and elastase in strains isolated from the renal @entity1 with @entity1212 and CAPD-associated @entity298 , compared with a non-septic control group. These phenotypic characteristics may therefore have a role in the maintenance of @entity1212 in renal @entity1 .
