INTRODUCTION: Contamination of the preservation solution may contribute to septic complications that can occur after transplantation and cause higher morbidity and mortality among recipients. The aim of this study was to determine potential donor-related predictors of positive microbiological findings in the preservation solution. DESIGN: We retrospectively studied 16 donor parameters on data from our center for microbiological findings in the preservation solution used in solid-organ recovery...

INTRODUCTION: The two-stage revision protocol is the gold standard for controlling and treating low-grade prosthetic joint infections of total hip and total knee arthroplasty. The antibiotic pause for diagnostic reasons before reconstruction (stage two) is discussed in relation to the persistence of the infection and the development of resistant bacterial strains. Serological markers and a synovial analysis are commonly used to exclude the persistence of infection. Therefore, we asked (1) is the serological testing of C-reactive protein and leucocytes a valuable tool to predict a persistence of infection? and (2) what is the role of synovial aspiration of Plymethylmethacrylat (PMMA) spacers in hip and knee joints? MATERIALS AND METHODS: One hundred twelve patients who were MSIS criteria-positive for a prosthetic joint infection were studied, including 45 total hip arthroplasties (THA) and 67 total knee artrhoplasties (TKA) patients...

Infections with coagulase-negative staphylococci (CoNS) can involve the production of toxins such as superantigens, which contribute to tissue degradation and inflammatory immune responses. The accessory gene regulator (agr) quorum sensing system coordinates the expression of most S. aureus virulence factors. Therefore, the aim of this study was to investigate the expression of these superantigens and the presence of the agr locus in CoNS strains isolated from blood cultures. PCR was used to detect enterotoxin and agr genes and expression was analyzed by RT-PCR...

AIM: The present study aimed to investigate the impact of the educational intervention for hand hygiene (HH) on knowledge, attitude, and mean colony-forming bacterial counts and type of bacteria on hands of undergraduate dental students. MATERIALS AND METHODS: A total of 86 dental students from different clinical grades were included in the study. They were divided into two groups, group I (55 students) received onetime educational session for HH at the start of the academic year and group II (31 students) received an extra reenforce-ment session 6 months later...

Coagulase-negative staphylococci (CoNS) and Staphylococcus aureus are part of the natural flora of humans and other mammals. We found that spent media from the CoNS species Staphylococcus caprae can inhibit agr-mediated quorum sensing by all classes of S. aureus. A biochemical assessment of the inhibitory activity suggested that the S. caprae autoinducing peptide (AIP) was responsible, and mass spectrometric analysis identified the S. caprae AIP as an eight-residue peptide (YSTCSYYF). Using a murine model of intradermal MRSA infection, the therapeutic efficacy of synthetic S...

In the last few years, the demand for the tremendous therapeutic applications of indigenous probiotic bacteria from diversified fermented food products has surged. In view of this, the present study was documented to evaluate the anti-tubercular and probiotic properties of coagulase-negative staphylococci (CNS) indigenous to Koozh, a traditional fermented food product of South India. A total of 18 isolates were purified from Koozh, and tested for anti-tubercular activity against Mycobacterium tuberculosis H37Rv using luciferase reporter phage (LRP) assay...

BACKGROUND: Central line-associated bloodstream infections (CLABSIs) account for significant morbidity and mortality in patients with long-term central venous catheters (CVCs). This study was performed to identify the characteristics and risk factors of CLABSIs among children with long-term CVCs. METHODS: A retrospective review of children who had a long-term CVC in Seoul National University Children's Hospital between 2011 and 2015 was performed. Data on patient demographics, the isolated pathogens, and the status of CVC placement were collected...

INTRODUCTION: Analysis of joint aspirate is the standard preoperative investigation for diagnosis of periprosthetic joint infection (PJI). We compared the diagnostic performance of culture and multiplex polymerase chain reaction (PCR) of synovial fluid for diagnosis of PJI. PATIENTS AND METHODS: Patients in whom aspiration of the prosthetic hip or knee joint was performed before revision arthroplasty were prospectively included. The performance of synovial fluid culture and multiplex PCR was compared by McNemar's chi-squared test...

BACKGROUND: Bacterial colonization of spinal implants may cause severe complications in patients with early-onset scoliosis. Correct diagnosis and detection of microbiologic formation is crucial to prevent delayed infections caused by bacterial colonization. The purposes of this study were to estimate the rate and risk factors of colonization of vertical expandable prosthetic titanium rib (VEPTR) implants in children and to compare the different methods for detecting microbiologic formation on the spinal implants...

Aggregated data from the Polish Point Prevalence Survey of Healthcare Associated Infections and Antimicrobial Use (PPS HAI&AU) collected between 2012 and 2015 were used to describe the epidemiology of healthcare associated bloodstream infections (BSI) in Polish hospitals, in order to assess the rationale for introducing a BSI surveillance programme in our country and analyse selected risk factors. Data were collected according to the ECDC PPS HAI&AU protocol. Within four years, records for 71,039 patients were collected in 36 (2012), 32 (2013), 112 (2014), and 158 (2015) hospitals; representativeness was evaluated as good in 2012-2013, and excellent from 2014...

A 77-year-old man visited our hospital with unstable gait following 2 months of anorexia. Brain MRI showed multiple infarcts; cardiac echocardiography revealed mitral-valve vegetation; and blood culture revealed methicillin-resistant coagulase-negative staphylococci. The patient was diagnosed with infective endocarditis (IE). Subarachnoid hemorrhage (SAH) developed ten days after antibiotic treatment. Intracranial aneurysm was not found. We speculated that chronic inflammation of the cerebral arterial walls by bacteria of low virulence was associated with SAH complication...

Staphylococcus schleiferi is a beta-hemolytic, coagulase-variable colonizer of small animals that can cause opportunistic infections in humans. In veterinary isolates, mecA-mediated oxacillin resistance is significant, with reported resistance rates of >39%. The goal of this study was to evaluate oxacillin and cefoxitin disk diffusion (DD) and minimum inhibitory concentration (MIC) breakpoints for detection of mecA-mediated oxacillin resistance in 52 human and 38 veterinary isolates of S. schleiferi Isolates were tested on multiple brands of commercial media following Clinical and Laboratory Standards Institute (CLSI) methods...

Dalbavancin is a lipoglycopeptide with a very prolonged half-life that enables treatments with a single IV administration that has been approved to treat complicated skin and soft tissue infections. Information on the efficacy and safety of Dalbavancin in other situations is very scarce. This retrospective study includes adult patients who received at least one dose of Dalbavancin between 2016 and 2017 in 29 institutions in Spain. Primary objective was to report the use of Dalbavancin in clinical practice including its efficacy and tolerability...

BACKGROUND: Mycoplasma mastitis is increasingly posing significant impact on dairy industry. Although the effects of major conventional mastitis pathogens on milk components has been widely addressed in the literature, limited data on the effects of different Mycoplasma and Acholeplasma spp. on milk quality and quantity is available. The aim of this study was to determine the casual relationship of Mycoplasma spp. and A. laidlawii to mastitis and compare them to subclinical mastitis caused by conventional mastitis pathogens from a single dairy herd in South Australia; Mycoplasma spp...

BACKGROUND: Bacteria are the major contributor of ocular infections worldwide. Ocular infections, if left untreated, can damage the structures of the eye with possible blindness and visual impairments. This work was aimed to review the bacterial profile of ocular infections. METHODS: Literature search was made in different electronic databases; the review was systematically made to get concrete findings. RESULTS: As far as this review, Staphylococcus aureus, Coagulase negative Staphylococci, Streptococcus pneumoniae and Pseudomonas aeruginosa are the leading isolates in ocular infections...
