Evaluation of the filmarray blood culture identification panel on diagnosis of bacteremias in an MDRO-endemic hospital environment.

The aim of the study was to evaluate the performance of the BCID2 FilmArray panel in relation to blood culture. 162 positive blood cultures were subjected to both classical microbiology methods and the FilmArray nested multiplex PCR. The BCID2 panel showed 96.

Antimicrobial resistance rates of Streptococcus pyogenes in a Greek tertiary care hospital: 6-year data and literature review.

Streptococcus pyogenes is responsible for various clinical manifestations in patients of all ages worldwide. Worryingly, an increase in antibiotic resistance rates of S. pyogenes has been observed in many countries.

In Vitro Synergistic Activity of Antimicrobial Combinations against Carbapenem- and Colistin-Resistant and .

Polymyxins are commonly used as the last resort for the treatment of MDR and nosocomial infections; however, apart from the already known toxicity issues, resistance to these agents is emerging. In the present study, we assessed the in vitro synergistic activity of antimicrobial combinations against carbapenem-resistant and colistin-resistant and in an effort to provide more options for their treatment. Two hundred and one hundred and six single clinical isolates with resistance to carbapenems and colistin, recovered between 1 January 2021 and 31 July 2022,were included.

Microbiological characteristics of bacteremias among COVID-19 hospitalized patients in a tertiary referral hospital in Northern Greece during the second epidemic wave.

Northern Greece was struck by an intense second COVID-19 (coronavirus disease 2019) epidemic wave during the fall of 2020. Because of the coinciding silent epidemic of multidrug-resistant organisms, the handling of COVID-19 patients became even more challenging. In the present study, the microbiological characteristics of bacteremias in confirmed cases of hospitalized COVID-19 patients were determined.

In vitro activity of ceftaroline against methicillin-resistant and methicillin-susceptible Staphylococcus aureus clinical isolates from a tertiary hospital in Greece.

Ceftaroline is a novel cephalosporin able to bind to and inhibit PBP2a, and thus active against methicillin-resistant Staphylococcus aureus. In the present study we assessed the in vitro activity of ceftaroline and comparators against a large sample of methicillin-resistant and methicillin-susceptible S. aureus isolates collected at our hospital.

Performance evaluation of AlfredAST rapid susceptibility testing directly from positive blood cultures in the routine laboratory workflow.

The aim of this study was to evaluate the performance of the new automated system AlfredAST which is based on light scattering technology for rapid susceptibility testing directly from positive blood cultures as well as its applicability in the routine laboratory workflow. We evaluated 176 significant episodes of bacteremia due to 92 Gram-negative and 84 Gram-positive bacteria. The antimicrobial agents tested were ceftriaxone, ciprofloxacin, gentamicin, meropenem, piperacillin-tazobactam, and colistin for Gram negatives and cefoxitin, vancomycin, linezolid, and daptomycin for Gram positives.

Comparative evaluation of minocycline susceptibility testing methods in carbapenem-resistant Acinetobacter baumannii.

In this study, the performance of two commonly used routine antimicrobial susceptibility testing methods, the automated VITEK(®)2 system and Etest (bioMérieux, Marcy-l'Étoile, France), was compared with the standard broth microdilution (BMD) method on 87 multidrug- and carbapenem-resistant Acinetobacter baumannii clinical isolates. Clinical and Laboratory Standards Institute (CLSI) 2015 breakpoints (susceptible, ≤4 mg/L; intermediate, 8 mg/L; and resistant, ≥16 mg/L) were used. Minocycline showed excellent activity, with 94.

Candida albicans colonization on an intragastric balloon.

Here we present the case of Candida albicans colonization on an intragastric balloon placed for weight loss. A 52-year-old obese woman achieved a BMI reduction of 10.9 kg/m(2) within 7 months as a result of a BioEnterics Intragastric Balloon and a well-balanced, low-calorie diet.

Enterobius vermicularis: a rare cause of appendicitis.

Objective: Although appendicitis is one of the most common causes of emergency surgery, parasites are rarely found associated with inflammation of the appendix. The aim of this study is to establish the prevalence of Enterobius vermicularis in surgically removed appendices, as well as to determine its possible role in the pathogenesis of appendicitis.

Methods: A retrospective analysis of all the appendices removed during the last 20 years at a tertiary university hospital.
