From the approximately 10% of men having prostatitis, 7% experience a bacterial prostatitis. The purpose of this study was to investigate the prevalence of uropathogens associated with UTIs in older patients with benign prostatic hyperplasia and to assess their susceptibility to commonly prescribed antibiotics as well as the relationships between microbial virulence and resistance features. Uropathogenic Escherichia coli was found to be the most frequent bacterial strain isolated from patients with benign prostatic hyperplasia, followed by Enterococcus spp., Enterobacter spp., Klebsiella spp., Proteus spp., Pseudomonas aeruginosa, and Serratia marcescens. Increased resistance rates to tetracyclines, quinolones, and sulfonamides were registered. Besides their resistance profiles, the uropathogenic isolates produced various virulence factors with possible implications in the pathogenesis process. The great majority of the uropathogenic isolates revealed a high capacity to adhere to HEp-2 cell monolayer in vitro, mostly exhibiting a localized adherence pattern. Differences in the repertoire of soluble virulence factors that can affect bacterial growth and persistence within the urinary tract were detected. The Gram-negative strains produced pore-forming toxins\u2014such as hemolysins, lecithinases, and lipases\u2014proteases, siderophore-like molecules resulted from the esculin hydrolysis and amylases, while Enterococcus sp. strains were positive only for caseinase and esculin hydrolase. Our study demonstrates that necessity of investigating the etiology and local resistance patterns of uropathogenic organisms, which is crucial for determining appropriate empirical antibiotic treatment in elderly patients with UTI, while establishing correlations between resistance and virulence profiles could provide valuable input about the clinical evolution and recurrence rates of UTI.<\/jats:p>","DOI":"10.3390\/pathogens6020022","type":"journal-article","created":{"date-parts":[[2017,5,31]],"date-time":"2017-05-31T10:41:04Z","timestamp":1496227264000},"page":"22","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Antibiotic Resistance and Virulence Phenotypes of Recent Bacterial Strains Isolated from Urinary Tract Infections in Elderly Patients with Prostatic Disease"],"prefix":"10.3390","volume":"6","author":[{"given":"Cristina","family":"Delcaru","sequence":"first","affiliation":[{"name":"Earth, Environmental and Life Sciences Section, Research Institute of the University of Bucharest (ICUB), 91\u201395 Independen\u0163ei Avenue, 0500088 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paulina","family":"Podgoreanu","sequence":"additional","affiliation":[{"name":"Iancului Private Laboratory, 060101 Bucharest, Romania"},{"name":"Department of Microbiology &amp; Immunology, Faculty of Biology, University of Bucharest, 1\u20133 Portocalelor Lane, Sector 6, 060101 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ionela","family":"Alexandru","sequence":"additional","affiliation":[{"name":"Iancului Private Laboratory, 060101 Bucharest, Romania"},{"name":"Department of Microbiology &amp; Immunology, Faculty of Biology, University of Bucharest, 1\u20133 Portocalelor Lane, Sector 6, 060101 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nela","family":"Popescu","sequence":"additional","affiliation":[{"name":"Iancului Private Laboratory, 060101 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lumini\u0163a","family":"M\u0103ru\u0163escu","sequence":"additional","affiliation":[{"name":"Department of Microbiology &amp; Immunology, Faculty of Biology, University of Bucharest, 1\u20133 Portocalelor Lane, Sector 6, 060101 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Coralia","family":"Bleotu","sequence":"additional","affiliation":[{"name":"\u015etefan S.
