Associations of virulence genotype and phylogenetic background with epidemiological factors (primary source of bacteremia, host compromise status, and hospital versus community origin) were assessed among 182 Escherichia coli blood isolates from adults with diverse-source bacteremia in comparison with fecal controls from the E. coli Reference collection. A continuum of virulence was found, from...

In a retrospective study, 80 episodes of nontyphoid salmonella (NTS) bacteremia in children were compared with 55 episodes in adults over a 10-year period. The study disclosed major differences in the predisposition, clinical presentation, and outcome as well as the microbiology of NTS bacteremia in relation to age. Adults were more likely than children to have predisposing diseases (95% vs. 15...

BACKGROUND To elucidate the clinical presentation, antimicrobial susceptibility, and prognostic factors of monomicrobial Aeromonas bacteremia in order to determine the most effective optimal therapy. MATERIALS AND METHODS We reviewed the medical records of Aeromonas bacteremia patients for the period January 2000 to December 2013 in a retrospective multi-center study. RESULTS A total of 336...

morganella morganii is rarely isolated from nosocomial infections. however, postoperative infections due to morganella spp. were documented in literature and eye involvements of the infections usually result in severe sequels.  we present a severe case infection, which was caused by m. morganii subsp . morganii, firstly appearing as conjunctivitis and complicated by bacteremia. the infectious a...

BACKGROUND/PURPOSE Nosocomial bacterial resistance has been advanced and well studied in Taiwan, but there were few reports describing the antibiotic susceptibility of community-acquired pathogens. Through collecting data from those who received blood cultures in emergency department, we presented an epidemiological study to analyze appropriate empirical therapy for the community-acquired bacte...

BACKGROUND The primary aim of this study was to describe the frequency of pulmonary infiltrates on chest X-ray (CXR) during community acquired Gram-negative bacteremia at a single centre in Denmark. METHODS The patients were retrospectively identified from the laboratory information system and clinical and radiological data were retrieved from the electronic health records. Overall 114 patien...

INTRODUCTION Enterobacter cloacae is responsible for 65-75% of all Enterobacter infections, bacteremia being the most common syndrome. The majority of infections are nosocomially acquired and in patients with predisposing factors. CASE PRESENTATION We present a case of E. cloacae bacteremia secondary to acute cholecystitis in a 60-year-old man with recent diagnosis of cholelithiasis. The diag...

One case of primary Desulfovibrio desulfuricans bacteremia in an immunocompetent man is presented, and 15 other reported cases are reviewed. While most isolates have not been identified to the species level, Desulfovibrio fairfieldensis and D. desulfuricans have been associated with incidents of bacteremia and D. vulgaris has been associated with intra-abdominal infections. In vitro studies sug...

Methods For a 3 months period we have studied all cases of primary and secondary bacteremia occurred in patients hospitalized in ICU of KAT Hospital in Athens. The patients’ demographic data, the reason of admission, the day when bacteremia occurred, the cultured microbe and its resistance to antibiotics as well as the duration of patients’ hospitalization in ICU have been recorded. The statist...

Vibrio cholerae are Gram-negative bacteria that are differentiated into O1/O139 and non-O1/non-O139 serogroups depending on their ability to agglutinate with specific antiserum. In contrast to non-O1/non-0139 Vibrio cholerae, which are more prone to invade the bloodstream, Vibrio cholerae O1 is rarely the cause of bacteremia. We report a case of O1 Vibrio cholera bacteremia and primary peritoni...
