Although fluoroquinolones are first-line agents for the treatment of National Institutes of Health (NIH) category II chronic bacterial prostatitis (CBP), therapy with these agents is not always feasible due to the increasing worldwide resistance of causative uropathogens. New therapeutic options are urgently required, as drugs such as β-lactam antibiotics distribute poorly to prostatic sites of infection and trimethoprim therapy is often unfeasible due to high resistance rates. The present study aimed to analyze the efficacy of aminoglycosides, administered to a cohort of 78 patients affected by fluoroquinolone-resistant CBP, or excluded from fluoroquinolone therapy due to various contraindications...

Adherent/invasive Escherichia coli (AIEC) strains are recently receiving increased attention because they are more prevalent and persistent in the intestine of Crohn (CD) patients than in healthy subjects. Since AIEC strains show a high percentage of similarity with ExPEC NMEC and UPEC, here we compared AIEC strain LF82 with a UPEC isolate (strain EC73) to assess whether LF82 could be able to infect prostate cells, as an extra-intestinal target. The virulence phenotypes of both strains were determined by using the RWPE-1 prostate cell line...

Basic applications in cancer therapy may fail to eradicate cancer cells completely, they can show toxic affects to healthy cells and development of resistance to antitumor agents may increase tendency to metastasis. Bacterial therapies have the advantage of specific targetting of tumors by selective toxicity, responsiveness to external signals, self-propelling capacity, and the sense of microenvironment. The most interest on the bacterial cancer therapy is about Salmonella spp. with a special emphasis of S...

BACKGROUND: Prostate abscess is usually a complication of acute urinary tract infection. Invasive liver abscess syndrome is characterized with Klebsiella pneumoniae related multiple organ metastasis. Concomitant pyogenic liver abscess and prostate abscess have rarely been reported. Recurrent episode of liver abscess is even rarer. CASE PRESENTATION: We report a 71-year-old male with acute bacterial prostate abscess and urinary tract infection caused by K. pneumoniae associated with multiple liver abscess, psoas muscle abscess and osteomyelitis...

Attenuated Salmonella typhimurium injected in the circulatory system of mammals selectively targets tumors. Using weekly intraperitoneal injections of attenuated Salmonella strain CRC2631, we tested for regression and/or inhibition of tumor development in the TRAMP prostate tumor mouse model, which utilizes SV40 early region expression for autochthonous formation of prostate tumors that progress into metastatic, poorly differentiated prostatic carcinomas in an immunocompetent murine model. Thirteen weekly intraperitoneal administrations of 105-107 CFU CRC2631 into 10 week old mice were well tolerated by the TRAMP model...

BACKGROUND: In most cases, prostatitis can be caused by a bacterial agent such as Ureaplasma urealyticum. Considering to the cumbersome of the culture method for the detection of Ureaplasma species in clinical samples such as prostate; PCR method that is faster and more appropriate than the cultivation methods, can be utilized for the detection of U. urealyticum and U. parvum. PCR-RFLP method can differentiate both biovars and assist in studies of the clinical diagnosis, epidemiology and pathology of this species in human...

Fluoroquinolones are considered as gold standard for the prevention of bacterial infections after transrectal ultrasound guided prostate biopsy. However, recent studies reported that fluoroquinolone- resistant bacterial strains are responsible for gradually increasing number of infections after transrectal prostate biopsy. In daily clinical practice, antibacterial efficacy is evaluated only in vitro, by measuring the reaction of bacteria with an antimicrobial agent in culture media (i.e. calculation of minimal inhibitory concentration)...

Urinary tract infections caused by uropathogenic Escherichia coli (UPEC) pathovars belong to the most frequent infections in humans. In men, pathogens can also spread to the genital tract via the continuous ductal system, eliciting bacterial prostatitis and/or epididymo-orchitis. Antibiotic treatment usually clears pathogens in acute epididymitis; however, the fertility of patients can be permanently impaired. Because a premature acrosome reaction was observed in an UPEC epididymitis mouse model, and sialidases on the sperm surface are considered to be activated via proteases of the acrosome, we aimed to investigate whether alterations of the sialome of epididymal spermatozoa and surrounding epithelial cells occur during UPEC infection...
