BACKGROUND Native vertebral osteomyelitis (NVO) is a common form of hematogenous osteomyelitis, with Staphylococcus aureus (S. aureus) being the most commonly isolated organism. Dalbavancin is approved by the US Food and Drug Administration (FDA) for the treatment of acute bacterial skin and skin structure infections (ABSSSI) and has a sufficiently promising pharmacokinetic and pharmacodynamic profile to be considered for the treatment of vertebral osteomyelitis. We describe here what is probably the first reported case of using multiple weekly dalbavancin to treat a complicated methicillin-resistant Staphylococcus aureus (MRSA) bacteremia and vertebral osteomyelitis...

BACKGROUND: For people requiring hemodialysis, infectious mortality is independently associated with geographic distance from a nephrologist. We aimed to determine if differential management of catheter-related blood stream infections (CRBSIs) could explain poorer outcomes. METHODS: We prospectively collected data from adults initiating hemodialysis with a central venous catheter between 2005 and 2015 in Alberta, Canada. We collected indicators of CRBSI management (timely catheter removal, relapsing bacteremia); frequency of CRBSIs; hospitalizations; predictors of CRBSIs, and bacteremia...

BACKGROUND: The route of Helicobacter cinaedi bacteremia has not yet been clarified. Although bacterial translocation from the intestinal tract into the circulation has been suggested, it has not been demonstrated thus far. The objective of this study was to investigate the port of entry of this bacterium. MATERIAL AND METHODS: We conducted a retrospective study on patients with H. cinaedi bacteremia between March 2009 and May 2013. Records of patients in whom H...

This article presents the case of a patient with newly developed skin erosions and ulcerations following an exanthematous drug eruption due to sultamicillin therapy. The skin lesions were treated topically with clobetasol and prednicarbate and orally with methylprednisolone. A skin smear revealed massive growth of Escherichia coli bacteria. Blood cultures were negative. The cause for developing ecthyma gangrenosum in our patient were iatrogenic immunosuppression and transient bacteremia.

Nontyphoidal Salmonellae commonly cause invasive disease in African children that is often fatal. The clinical diagnosis of these infections is hampered by the absence of a clear clinical syndrome. Drug resistance means that empirical antibiotic therapy is often ineffective and currently no vaccine is available. The study objective was to identify risk factors for mortality among children presenting to hospital with invasive Salmonella disease in Africa. We conducted a prospective study enrolling consecutive children with microbiologically-confirmed invasive Salmonella disease admitted to Queen Elizabeth Central Hospital, Blantyre, in 2006...

A 54-year-old woman with Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ALL) underwent hematopoietic stem cell transplantation from an HLA-matched sibling. Subsequently, she suffered from chronic graft versus host disease (GvHD) and received medical treatment. Fever developed on day 697 and resulted in a shock state at 10 h after the visit. Achromobacter xylosoxidans was detected in the initial blood culture on day 699. General conditions exacerbated even after the start of meropenem hydrate (MEPM, Meropen®) administration, with Corynebacterium striatum detected as an additional species in the initial blood culture on day 701...

OBJECTIVE: Single dose of systemic antibiotics and short-term use of mouthwashes reduce bacteremia. However, the effects of a single dose of preprocedural rinse are still controversial. This study evaluated, in periodontally diseased patients, the effects of a pre-procedural mouth rinse on induced bacteremia. MATERIAL AND METHODS: Systemically healthy individuals with gingivitis (n=27) or periodontitis (n = 27) were randomly allocated through a sealed envelope system to: 0...

Klebsiella pneumoniae is one of the most clinically relevant species in immunocompromised individuals responsible for community-acquired and nosocomial infections, including pneumonias, urinary tract infections, bacteremias, and liver abscesses. Since the mid-1980s, hypervirulent K. pneumoniae, generally associated with the hypermucoviscosity phenotype, has emerged as a clinically significant pathogen responsible for serious disseminated infections, such as pyogenic liver abscesses, osteomyelitis, and endophthalmitis, in a generally younger and healthier population...

Lactobacillus species are a commensal flora of the human gastrointestinal and the female genitourinary tract. Lactobacilli especially the rhamnosus species, are common components of commercial probiotics. They are rarely associated with pathology in immunocompetent people, but they have been known to cause dental caries, bacteremia, and endocarditis in patients with suppressed immune function. Cases of Lactobacillus bacteremia have been reported in patients with acute myeloid leukemia, large granular lymphocytic leukemia, and in transplant recipients...

A carbapenem resistant but ceftriaxone and cefepime susceptible Klebsiella oxytoca was isolated from the blood of a patient with polymicrobial bacteremia after 2 weeks of ertapenem treatment. Whole-genome sequencing identified no carbapenemase gene nor plasmid, but only blaOXY-2-8 gene with a mutation in the promoter that's been reported to increase its expression. Two other specific carbapenem resistance mechanisms including mutated porin genes and the AcrAB-TolC efflux system genes were also identified. Clinicians need to be aware of such unusual antibiogram and should not assume carbapenems are always broader spectrum antibiotics than expanded-spectrum cephalosporins...

Carbapenem-resistant Enterobacteriaceae (CRE) infection is highly endemic in China, but estimates of infection burden are lacking. We established incidence of CRE infection from a multicenter study that covered 25 tertiary hospitals in 14 provinces. CRE cases defined as carbapenem non-susceptible C. freundii, E. coli, E. cloacae, or K. pneumoniae infections during January to December 2015 were collected and reviewed from medical records. Antimicrobial susceptibility testing and carbapenemase genes identification were performed...

Objective: It has been shown in previous studies that inadequate empirical treatment is associated with mortality in a variety of infections caused by Gram-negative bacteria. In this study, the clinical effect of discordance in empirical treatment was investigated in patients with urinary tract infection (UTI) accompanied by bacteremia. Material and methods: We retrospectively reviewed the files of adult (>18 years old) patients who were diagnosed with UTI in our clinic between January 2014 and December 2015...

Background: Clostridium perfringens is ubiquitous in nature. It is a normal inhabitant in the intestinal tract of animals and humans. As the primary etiological agent of gas gangrene, necrosis and bacteremia, C. perfringens causes food poisoning, necrotic enteritis (NE), and even death. Epidemiology research has indicated that the increasing incidence of NE in poultry is associated with the withdrawal of in-feed antibiotic growth promoters in poultry production in response to government regulations...

The aim of this study was to evaluate the procalcitonin (PCT) changes in two different high-dose colistin regimens in the treatment of multi-drug resistant MDR gram negative infections in ICU patients. This is a prospective study of adult ICU patients with bacteremia and ventilator associated pneumonia (VAP) caused by MDR gram negative pathogens. Patients were assigned to two colistin administration groups. Group A received 9 and group B received 3 million international units every 24 and 8 h respectively. Baseline characteristics and measurements of PCT concentrations at the start, the 3rd and the 5th day of the antibiotic therapy and their trends between the two groups were recorded and compared...

High-risk neuroblastoma is an aggressive childhood cancer with poor outcomes. Treatment begins with an induction phase comprised of intense multi-agent chemotherapy with the goal of maximally reducing tumor bulk. Given the high intensity of induction chemotherapy, neutropenic fever and infectious complications are common; however, the actual incidence is difficult to determine from clinical trial reports. We performed a retrospective review of infection-related complications in 76 children treated for high-risk neuroblastoma at Texas Children's Hospital...

BACKGROUND: In the eighties, a multidrug resistant clone of Salmonella Typhimurium DT104 emerged in UK and disseminated worldwide. This clone harbored a Salmonella genomic island 1 (SGI1) that consists of a backbone and a multidrug resistant region encoding for penta-resistance (ampicillin, chloramphenicol/florfenicol, streptomycin/spectinomycin, sulphonamides and tetracycline (ACSSuT)). Several authors suggested that SGI1 might have a potential role in enhancement of virulence properties of Salmonella enterica...
