Enterococcus was chosen for these trials since it is a common urinary pathogen in patients with an indwelling urinary catheter.<h4>Materials and methods</h4>Each experiment tested 3 growth conditions. Group 1 or E. coli plus Enterococcus catheters were exposed to E. coli 83972 for 24 hours and then to Enterococcus for 30 minutes. Group 2 or E. coli alone catheters were incubated in E. coli for 24 hours and then in sterile broth for 30 minutes. Group 3 or Enterococcus alone catheters did not undergo the initial incubation with E. coli before the 30-minute incubation with Enterococcus: All catheters were then incubated in sterile human urine for 24 hours. Catheters were washed with saline and cut into 5, 1 cm. segments. Each segment was sonicated and the sonication fluid was diluted and plated. The results of each of the 5 segments were averaged and the set of experiments was repeated 7 times.<h4>Results</h4>A preexisting coating of E. coli 83972 reduced catheter colonization by E. faecalis 210 more than 10-fold. Enterococcus alone catheters had a median of 9.7 x 10(5) enterococci per cm., whereas E. coli plus Enterococcus catheters had a median of 0.38 x 10(5) enterococci per cm. (p = 0.016).<h4>Conclusions</h4>Pre-inoculating urinary catheters with E. coli 83972 significantly impedes catheter colonization by Enterococcus: These promising in vitro results prompt the clinical investigation of this particular application of bacterial interference.","is_dataset_classified":null,"base_score":0.0,"endowment":0.0,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"11743359","pmcid":"PMC2963589","openalex_id":null,"authors":[],"funders":[{"funder_name":"NICHD NIH HHS","grant_id":"K23 HD042014","title":null}],"total_grants":1,"fwci":null,"citation_percentile":null,"influential_citations":0,"citation_trend":[],"oa_status":"closed","license":"http://www.elsevier.com/tdm/userlicense/1.0/","oa_locations":[{"url":"http://api.elsevier.com/content/article/PII:S0022534705654717?httpAccept=text/xml","host_type":"publisher"},{"url":"http://api.elsevier.com/content/article/PII:S0022534705654717?httpAccept=text/plain","host_type":"publisher"},{"url":"http://www.jurology.com/doi/pdf/10.1016/S0022-5347%2805%2965471-7","host_type":"publisher"}],"fields_of_study":[],"mesh_terms":["Urine","Humans","Escherichia coli","Enterococcus faecalis","Urinary Catheterization","Catheters, Indwelling","Antibiosis","In Vitro Techniques"],"keywords":[],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-17T13:26:10.856740Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
