Urinary tract infections (UTIs) are one of childhood’s most common bacterial infections. The study aimed to determine the clinical symptoms, laboratory tests, risk factors, and etiology different UTIs in children admitted pediatric hospitals for three years. Methods: Patients with positive urine cultures diagnosed acute pyelonephritis (APN) or cystitis (CYS) were analyzed etiology, depending on their age sex. Results: We studied 948 (531 girls 417 boys), a median 12 (IQR 5−48 months). A...
Since the SARS-CoV-2 outbreak, many countries have introduced measures to limit transmission. The data based on ICD-10 codes of lower respiratory tract infections and microbiological analysis gastrointestinal were collected. retrospective five-year medical records revealed a substantial decrease in during pandemic year (from April 2020 March 2021). We noted an 81% decline LRTI-associated hospital admissions mean 1170 per previous four years 225 between through According analysis, there 100%,...
Despite being implicated in a wide spectrum of community- and healthcare-acquired infections, anaerobes have not yet been incorporated into systematic surveillance programs Europe. We conducted multicentre retrospective observational study analysing all anaerobic strains isolated from blood cultures 44 European Hospital Centres over 4-year period (2020-2023). Diagnostic approach, epidemiology, antimicrobial susceptibility according to EUCAST v. 15.0 were investigated. Our included 14,527...
Ticks are recognized as the main vectors and reservoirs of spotted fever group rickettsiae. We searched for most prevalent Rickettsia spp. in Poland found R. slovaca helvetica bacteria ticks southern central Poland; raoulti was all parts Poland.
The presence of antibodies to Rickettsia conorii, R. helvetica, felis, slovaca, sibirica, and massiliae in sera 129 forest workers from northeastern southern Poland was assayed by indirect immunofluorescence. Previous environmental studies revealed spotted fever group (SFG) rickettsiae ticks collected these areas. Additionally, the were examinated for specific other tick-borne bacteria: Anaplasma phagocytophilum, Bartonella spp., B. burgdorferi. results have shown SFG 14.7% tested workers,...
Clinical data suggest that during the current COVID-19 pandemic, children are less prone than adults to SARS-CoV-2 infection. Our purpose was determine frequency of in vs. 2020 pandemic Warsaw, Poland, and investigate whether RSV and/or influenza A/B infections were associated with infections. We present results RT-PCR tests for performed Poland. Some pediatric subjects also PCR-tested RSV, A B influenza. compared test from four groups symptomatic asymptomatic subjects: 459 patients...
Abstract Shiga toxin-producing Escherichia coli (STEC) are zoonotic pathogens causing hemorrhagic colitis and hemolytic uremic syndrome (HUS) in children the elderly. Stool samples were collected from 180 hospitalized five pediatric centers Poland 2018–2022. Direct stx1 / stx2 gene detection by PCR feces E. isolates was performed. Antibiotic susceptibility tested according to EUCAST v.12. Randomly selected serotyped with O157 antiserum genotyped pulsed-field gel electrophoresis (PFGE). A...
Bartonella spp. is an etiologic agent of vector-borne infections. was searched for in adult Ixodes ricinus ticks removed from dogs and cats using specific polymerase chain reaction (PCR) sequence analysis gltA gene. henselae DNA detected 5 102 tested ticks. All PCR-positive were dogs. Four engorged, one unfed. The data demonstrate that B. able to inhabit This the first report about existence It is, however, open issue needs further investigation if consist a new competent vector involved...
Hematophagous Spinturnix myoti mites and their host, the greater mouse-eared bat (Myotis myotis), were tested for presence of Bartonella spp., Rickettsia Anaplasma phagocytophilum. In total, spp. DNA was amplified in 28% 134 mite pools 25% 59 bats by PCR targeting a fragment citrate synthase gltA gen. Adult at least threefold more frequently infected compared to immature stages. The overall infection prevalence among from cave-dwelling higher than those collected attic shelters. Three...
The objective of this work was to compare the quality FMT preparations made from fresh feces with those frozen at -30°C without any pre-processing or cryopreservation additives. research hypothesis that such preservation protocol (frozen whole stool, then thawed and processed) is equipotent classical preparation. For that, three complementary methods were applied, including: (i) culturing in aerobic anaerobic conditions, (ii) measuring viability by flow cytometry, (iii) next-generation...
Urinary tract infections (UTIs) remain the most common diagnosed in outpatients and hospitalized patients. This study was designed to determine patterns of antibiotic resistance prevalence uropathogens causing UTIs pediatric patients between 1 January 2020 31 December 2022 at Teaching Hospital Warsaw. The frequent species isolated from urine samples were E. coli (64.5%), Klebsiella spp. (11.6%), Enterococcus (6.1%). caused by Enterobacter spp., significantly more children younger than three...
To investigate the role of B. henselae in patients with symptoms suggesting neuroborreliosis, serum and cerebrospinal fluid samples were tested serological PCR methods. Among 17 examined patients, 12 cases Borrelia burgdorferi infections detected, 1 case Bartonella infection was ascertained, two mixed found. These results indicate that should be taken into consideration establishing diagnosis neurological disorders. Further study this conclusion is needed.
The aim of the study was to determine occurrence Bartonella henselae reservoir and vectors infection in close surroundings human beings urban areas central Poland. included mammals (54 dogs, 137 cats) 102 adult Ixodes ricinus ticks removed from cats dogs. Blood samples were drawn each animal cultured on chocolate agar plates mouse fibroblasts L-929 cell line culture. levels IgG antibodies determined by indirect immunofluorescence assay. spp. strains isolated blood 14 (10.2%). Isolates...
Abstract Purpose. There is increasing evidence that adventitial inflammation may participate in atherosclerosis development. The aim of this study was to investigate which atherosclerotic risk factors correlated with carotid thickness (AT) and compare them those associated intima‐media (IMT). We also set out test the hypothesis there a significant correlation between IMT AT arteries. Methods. far artery wall were measured by high‐resolution B‐mode ultrasound 128 persons (mean, 65 ± 8 years)....
Streptococcus intermedius is a commensal bacterium increasingly associated with brain abscesses. It can infect the through direct extension of an inflammatory process or hematogenous route. Meningitis due to this pathogen sporadic and has not been described in children before. We report case immunocompetent 6-year-old boy who developed bacterial meningitis S. .
Due to the fastidious nature of B. henselae and limited number available isolates worldwide, there are few data on its in vitro susceptibility antibiotics. We determined minimal inhibitory concentrations (MIC) ten antimicrobial agents against 11 feline by Etest method. The lowest MICs were obtained for rifampicin < or = 0.002 mg/L. all 0.016 mg/L ampicilin, amoxicillin/clavulanic acid, tetracycline ranged from 0.032 azithromycin. two tested fluoroquinolones: ciprofloxacin levofloxacin...
