Outbreak of healthcare-associated bacteremia caused by Burkholderia gladioli due to contaminated multidose vials with saline solutions in three Croatian hospitals.

Objectives: Burkholderia gladioli has been associated with infections in patients with cystic fibrosis, chronic granulomatous disease, and other immunocompromising conditions. The aim of this study was to better depict the outbreak of healthcare-associated bacteremia caused by B. gladioli due to exposure to contaminated multidose vials with saline solutions.

Live Intraoral of Lower Lip Mimicking Mucocele-First Reported Case from Croatia.

Dirofilariasis is an endemic infestation in tropical and subtropical countries caused by about 40 different species. It rarely occurs in the oral cavity and is mostly presented as mucosal and submucosal nodules. Differential diagnoses include lipoma, mucocele, and pleomorphic adenoma.

Prevention and control of meningococcal disease: Updates from the Global Meningococcal Initiative in Eastern Europe.

The Global Meningococcal Initiative (GMI) aims to prevent invasive meningococcal disease (IMD) worldwide through education, research and cooperation. In March 2019, a GMI meeting was held with a multidisciplinary group of experts and representatives from countries within Eastern Europe. Across the countries represented, IMD surveillance is largely in place, with incidence declining in recent decades and now generally at <1 case per 100,000 persons per year.

Identification of microorganisms on mobile phones of intensive care unit health care workers and medical students in the tertiary hospital.

Aim To identify and investigate a difference between microorganisms present on intensive care unit (ICU) health care workers' (HCW, doctors, nurses or medical technicians) and medical students' mobile phones as well as to investigate a difference between the frequency and the way of cleaning mobile phones. Methods Fifty swabs were collected from HCWs who work in the ICU (University Hospital Centre Osijek) and 60 swabs from medical students (School of Medicine, University of Osijek). Microorganisms were identified according to standard microbiological methods and biochemical tests to the genus/species level.

Molecular characterization of a collection of Neisseria meningitidis isolates from Croatia, June 2009 to January 2014.

In the last decade, the incidence of invasive meningococcal disease (IMD) in Croatia remained stable at approximately 1 case per 100 000 inhabitants, affecting mainly children aged ≤5 years. We report the molecular characterization of meningococci causing IMD occurring from June 2009 to January 2014 in Croatia. Genomic DNA from 50 clinical isolates was analysed for serogroup, multilocus sequence typing and allele type of the two outer membrane protein genes, porA and the iron-regulated fetA.

Septic abortion caused by Campylobacter jejuni bacteraemia.

A 20-year-old female patient, 14 weeks pregnant, was admitted to hospital with anamnestic and clinical features of acute pyelonephritis. Clinical signs of septic abortion developed and after obstetric examination the therapy was changed to ampicillin, gentamicin and clindamycin. Campylobacter jejuni was isolated from blood cultures.

Quantitative investigation of efficiency of ultraviolet and visible light in eradication of Candida albicans in vitro.

Objective: The aim of this study was to quantitatively investigate the efficiency of the ultraviolet (UV) and visible light in eradication of Candida albicans in vitro; in particular, to determine, for selected wavelengths, the specific eradication coefficients and thresholds in terms of energy density levels required to effect 3.0log10 and 4.0log10 reduction.

Meningococcal serogroup Y emergence in Europe: high importance in some European regions in 2012.

Neisseria meningitidis is differentiated into 12 distinct serogroups, of which A, B, C, W, X, and Y are medically most important and represent an important health problem in different parts of the world. The epidemiology of N. meningitidis is unpredictable over time and across geographic regions.

The polymicrobial Actinomyces naeslundii and Pseudomonas aeruginosa sepsis in a patient with ulcerative colitis 2 months after colonoscopy.

We describe a case of an abrupt onset of polymicrobial Actinomyces naeslundii/Pseudomonas aeruginosa sepsis in a patient with a previously silent abdominal actinomycosis, developed 2 months after colonoscopy when the diagnosis of a left-sided ulcerative colitis was established. Prolonged high-dose ceftriaxone therapy was clinically effective, albeit accompanied by the development of a reversible pseudocholelithiasis that persisted for 5 months.

Methicillin-susceptible Staphylococcus aureus endocarditis isolates are associated with clonal complex 30 genotype and a distinct repertoire of enterotoxins and adhesins.

Background: Using multinational collections of methicillin-susceptible Staphylococcus aureus (MSSA) isolates from infective endocarditis (IE) and soft tissue infections (STIs), we sought to (1) validate the finding that S. aureus in clonal complex (CC) 30 is associated with hematogenous complications and (2) test the hypothesis that specific genetic characteristics in S. aureus are associated with infection severity.

Heterogeneous vancomycin-intermediate susceptibility phenotype in bloodstream methicillin-resistant Staphylococcus aureus isolates from an international cohort of patients with infective endocarditis: prevalence, genotype, and clinical significance.

Background: The significance of heterogeneous vancomycin-intermediate Staphylococcus aureus (hVISA) is unknown. Using a multinational collection of isolates from methicillin-resistant S. aureus (MRSA) infective endocarditis (IE), we characterized patients with IE with and without hVISA, and we genotyped the infecting strains.

Listeria monocytogenes meningitis associated with rhabdomyolysis and acute renal failure.

Introduction: Numerous systemic infections are capable of inducing myositis and rhabdomyolysis. Clinical course of the disease is in the great majority of patients benign and without development of renal dysfunction. However, serious consequences are possible if acute renal failure (ARF) occurs, especially in critically ill patients.

Genotypic diversity of coagulase-negative staphylococci causing endocarditis: a global perspective.

Coagulase-negative staphylococci (CNS) are important causes of infective endocarditis (IE), but their microbiological profiles are poorly described. We performed DNA target sequencing and susceptibility testing for 91 patients with definite CNS IE who were identified from the International Collaboration on Endocarditis-Microbiology, a large, multicenter, multinational consortium. A hierarchy of gene sequences demonstrated great genetic diversity within CNS from patients with definite endocarditis that represented diverse geographic regions.

Moraxella lacunata: a rare cause of infective endocarditis.

We describe the first case of Moraxella lacunata definite native valve endocarditis in a patient with previously normal mitral valves. The disease was complicated with embolizations of the brain and spleen. After 6 weeks of antimicrobial treatment, valvular replacement was performed.

Target gene sequencing to characterize the penicillin G susceptibility of Neisseria meningitidis.

Clinical isolates of Neisseria meningitidis with reduced susceptibility to penicillin G (intermediate isolates, Pen(I)) harbor alterations in the penA gene encoding the penicillin binding protein 2 (PBP2). A 402-bp DNA fragment in the 3' half of penA was sequenced from a collection of 1,670 meningococcal clinical isolates from 22 countries that spanned 60 years. Phenotyping, genotyping, and the determination of MICs of penicillin G were also performed.
