We describe the case of a previously healthy 7-month-old male infant with urinary tract infection due to Staphylococcus epidermidis grown from two separate urine cultures. Further evaluation showed severe bilateral vesicoureteral reflux. Physicians should not assume that S. epidermidis is always a contaminant in urine cultures.

Bacterial resistance is gaining ground and novel, unconventional strategies are required to improve antibiotic treatments. As a synthetic analog of planktonic bacilli, the natural bacterial swimmers that can penetrate bacterial biofilms, ultra-short propelling magnetic nanochains are presented as bioinspired magnetic nanorobots, enhancing the antibiotic treatment in biofilm-forming Staphylococcus epidermidis. Propelling nanochains, activated by a low intensity (<20 mT) and low frequency (<10 Hz) rotating magnetic field (RMF), prompt the otherwise resistant biofilm-forming bacteria to become sensitive to methicillin, resulting in the killing of 99.

Background: Periprosthetic joint infections (PJI) are one of the most devastating complications of total knee arthroplasty (TKA). Patients who have chronic kidney disease (CKD) are more vulnerable to PJI. We aimed to answer the following questions: 1) What are the commonly observed pathogens in PJI after TKA in CKD patients, and do they differ from those in non-CKD patients? and 2) What are the risk factors for PJI after TKA in CKD patients?
Methods: Patients who underwent surgery due to a chronic PJI of the TKA were retrospectively enrolled.

is known for its potential antioxidant and anti-inflammatory properties, attributed to triterpenes, flavonoids, and tannins. This study aimed to optimise the extraction process for aerial parts of using vortex extraction. A Box-Behnken experimental design coupled with response surface methodology was employed to evaluate the effects of three independent variables: sample-to-solvent ratio, velocity, and temperature.

In this present investigation, plant-mediated synthesis of titanium oxide (TiO) nanoparticles was synthesized from seagrass (Thalassia hemprichi) using the hot plate combustion method (HPCM). Synthesized TiO nanoparticles optical, functional, structural, and morphology properties were analyzed by UV-visible spectroscopy, Fourier transform infrared spectroscopy (FT-IR), powder X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX). SEM analysis confirmed the spherical shape of the TiO nanoparticles were observed in various sizes, viz.

Understanding the changes in the prevalence of common uropathogens is essential for early diagnosis and effective treatment of UTIs. This study aims to identify etiological agents and determine the local antibiotic susceptibility patterns of uropathogens causing UTIs.
