INTRODUCTION: the purpose of this retrospective multicenter study was to assess whether the risk of developing bloodstream infections (BSI) due to carbapenem-resistant Klebsiella pneumoniae (CRKP) in colonized patients is influenced by the occurrence of BSI due to other pathogens. METHODS: from January 2012 to March 2014, all patients with at least one rectal swab positive for CRKP and at least 30 days of previous hospital stay were included in the study. The primary outcome measure was CRKP BSI, defined as a time-to-event endpoint...

Periodontal disease (PD) is generated by microorganisms. These microbes can enter the general circulation causing a bacteraemia. The result can be adverse systemic effects, which could promote conditions such as cardiovascular disease. Level A evidence supports that PD is independently associated with arterial disease. PD is a common chronic condition affecting the majority of Americans 30 years of age and older. Atherosclerosis remains the largest cause of death and disability. Studies indicate that the adverse cardiovascular effects from PD are due to a few putative or high-risk bacteria: Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola or Fusobacterium nucleatum There are three accepted essential elements in the pathogenesis of atherosclerosis: lipoprotein serum concentration, endothelial permeability and binding of lipoproteins in the arterial intima...

Extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-PE) are endemic pathogens worldwide. Infection with ESBL-PE may be associated with inadequate antibiotic therapy and a poor outcome. However, risk factors for ESBL-PE community-acquired infections are ill-defined. An observational multicentre study was performed in 50 hospitals to identify the prevalence of and risk factors for community-acquired ESBL-PE bacteraemia. All patients presenting with community-onset Enterobacteriaceae bacteraemia were recorded over a 2-month period (between June and November 2013)...

INTRODUCTION: Presepsin (sCD14-ST) is an emerging biomarker for infection. We hypothesized that presepsin could specifically increase during acute pyelonephritis and correlate with severity. METHODS: We compared presepsin values in patients with acute pyelonephritis and controls, and we assessed its capacity to predict bacteraemia and admission in patients. RESULTS: In 312 patients with acute pyelonephritis (median age 33years), presepsin concentrations were higher than in controls (476 vs 200ng/L, p<0...

This review is the result of discussions that took place at the 5th MRSA Working Group Consensus Meeting and explores the possible treatment options available for different types of infections due to methicillin-resistant Staphylococcus aureus (MRSA), focusing on those antibiotics that could represent a valid alternative to vancomycin. In fact, whilst vancomycin remains a viable option, its therapy is moving towards individualised dosing. Other drugs, such as the new lipoglycopeptides (oritavancin, dalbavancin and telavancin) and fifth-generation cephalosporins (ceftaroline and ceftobiprole), are showing good in vitro potency and in vivo efficacy, especially for patients infected with micro-organisms with higher vancomycin minimum inhibitory concentrations (MICs)...

Clostridial soft tissue infections are infrequent, but can be life-threatening when associated with certain underlying conditions, such as immunosuppression or malignancy. When bacteraemia occurs, it can be accompanied by haemolysis. Only surgical removal of the focus of infection and early onset of antibiotic therapy can prevent a very poor outcome. We describe the case of a man aged 65 years who presented with sepsis, haemolysis and rapid worsening. The identification of a gas-forming liver abscess, the early percutaneous drainage and the prompt initiation of antibiotic treatment were the key factors in the outcome of this patient...

BACKGROUND: Health care-associated infections (HAI) have been shown to increase length of stay, the cost of care, and rates of hospital deaths (Kaye and Marchaim, J Am Geriatr Soc 62(2):306-11, 2014; Roberts and Scott, Med Care 48(11):1026-35, 2010; Warren and Quadir, Crit Care Med 34(8):2084-9, 2006; Zimlichman and Henderson, JAMA Intern Med 173(22):2039-46, 2013). Importantly, infections acquired during a hospital stay have been shown to be preventable (Loveday and Wilson, J Hosp Infect 86:S1-70, 2014)...

BACKGROUND: Melioidiosis, infection by Burkholderia pseudomallei, is an important but frequently under-recognised cause of morbidity and mortality in Southeast Asia and elsewhere in the tropics. Data on the epidemiology of paediatric melioidosis in Cambodia are extremely limited. METHODS: Culture-positive melioidosis cases presenting to Angkor Hospital for Children, a non-governmental paediatric hospital located in Siem Reap, Northern Cambodia, between 1(st) January 2009 and 31(st) December 2013 were identified by searches of hospital and laboratory databases and logbooks...

A man aged 53 years was admitted to our hospital due to general malaise, fever and chills for the past 24 hours. He had a history of chronic alcoholic liver disease. The blood tests showed leucocytosis with neutrophilia, lactic acidosis and acute-phase reactants. The blood cultures were positive for Parvimonas micra, an anaerobic pathogen which is part of the flora of the oral cavity. There was no evidence of abscess formation in either the examination or the imaging tests, but in the work-up that followed, a gastroscopy showed a stenotic oesophageal mass that turned out to be an invasive squamous cell carcinoma...

PROBLEM: Complement is a central defence against sepsis, and increasing complement insufficiency in neonates of greater prematurity may predispose to increased sepsis. Ureaplasma spp. are the most frequently cultured bacteria from preterm blood samples. METHOD OF STUDY: A sheep model of intrauterine Ureaplasma parvum infection was used to examine in vivo Ureaplasma bacteraemia at early and late gestational ages. Complement function and Ureaplasma killing assays were used to determine the correlation between complement potency and bactericidal activity of sera ex vivo...

We describe the investigation and management of a pseudo-outbreak of Bacillus spp. bacteraemia associated with construction work in an emergency department (ED). During the pseudo-outbreak period 59 out of 3469 (1.7%) blood cultures yielded Bacillus spp. versus 24 out of 7628 (0.31%) in 2012. Material, surfaces, and air samples showed environmental contamination. Cases rapidly declined following the implementation of infection control measures and the end of construction. Construction works at the ED caused environmental contamination that most probably led to the pseudo-outbreak of Bacillus bacteraemia...

PURPOSE: Although there have been many publications regarding the risk factors for implant-associated orthopaedic infections, none have investigated how clinical presentations and epidemiology may differ between infections with and without osteosynthetic material. METHODS: We pooled clinical data from several databases of adult patients with orthopaedic infections hospitalized at Geneva University Hospitals from January 2004 to December 2014. RESULTS: Among 2740 episodes of orthopaedic infections, 76% were implant-free osteoarticular or soft tissue infections...

This paper describes an elderly male patient, living in the Veneto Region, Italy, who developed Vibrio cholerae bacteraemia and pneumonia. Some days previously, while on holiday in the Lagoon of Venice, he had been collecting clams in seawater, during which he suffered small abrasions of the skin. On admission to hospital, he was confused, had fever and a cough, but neither diarrhoea nor signs of gastroenteritis were found. Both blood and stool cultures grew V. cholerae of non-O1 non-O-139 type, and the patient recovered after prompt administration of intravenous ceftriaxone for 2 weeks...

Detection of carbapenemase-producing bacteria directly from blood cultures is a major challenge, as patients with bacteraemia are critically ill. Early detection can be helpful for selection of the most appropriate antibiotic therapy as well as adequate control of outbreaks. In the current study, a novel matrix-assisted laser desorption/ionisation time-of-flight (MALDI-TOF)-based method was developed for the rapid, automated detection of carbapenemase-producing Enterobacteriaceae, Pseudomonas aeruginosa and Acinetobacter baumannii directly from blood cultures...
