Background: , although remarked as harmless commensals of the intestinal tract of humans and animals, have become a significant source of infection in hospitalized patients worldwide.The present study aimed to isolate and identify enterococci from clinical samples and to determine the genotypic characteristics of vancomycin-resistant enterococcus isolates.
Materials And Methods: A total of 774 isolates of enterococci from clinical samples were identified to the species level, and their anti-microbial susceptibility pattern was determined by Kirby Bauer Disk Diffusion method and Vitek 2 automated system. Screening for vancomycin resistance was performed by using brain heart infusion agar containing 6 micrograms/ml of vancomycin. The minimum inhibitory concentration (MIC) of vancomycin was determined by the agar dilution method and Epsilometer test (E test). Genotyping was carried out for resistant isolates by multiplex polymerase chain reaction.
Results: Thirty (3.88%) isolates were resistant to vancomycin by agar screen method. Five isolates showed intermediate resistance with anMIC of 8-16 micrograms/ml for vancomycin by agar dilution. By the E test, two isolates displayed an MIC of ≥32 micrograms/ml for vancomycin and one isolate showed an MICof ≥32 micrograms/ml for teicoplanin.Van A was the common genotype isolated. The present study reports isolates of with a susceptible MIC for glycopeptide and the presence of the Van A gene.
Conclusion: Heterogeneous resistance among clinical isolates of was observed in our study. The predominant phenotype and genotype detected among clinical isolates were Van A.

Purpose: CytoSorb® (CS) adsorbent is a hemoadsorption filter for extracorporeal blood purification often integrated into continuous kidney replacement therapy (CKRT). It is primarily used in critically ill patients with sepsis and related conditions, including cytokine storms and systemic inflammatory responses. Up to now, there is no evidence nor recommendation for the use of CS filters in sepsis (22).

This study aimed to investigate the role of transforming growth factor-beta 3 (TGF-β3) secreted by adipose-derived stem cells (ADSCs) in suppressing melanin synthesis during the wound healing process, particularly in burn injuries, and to explore the underlying mechanisms involving the cAMP/PKA signaling pathway. ADSCs were isolated from C57BL/6 mice and characterized using flow cytometry and differentiation assays. A burn injury model was established in mice, followed by UVB irradiation to induce hyperpigmentation.

The study was conducted to detect the occurrence and phenotypic resistance pattern of ESBL-producing Enterobacteriaceae in livestock using docking based analysis to reveal the classes of antibiotics against which ESBL-producers are active. Rectal swabs from healthy cattle (n=100), goats (n=88), pigs (n=66) were collected from backyard farms in Andaman and Nicober island (India). In total, 304 isolates comprising E.

Background: Carbapenem-Resistant Gram-Negative Bacteria, including Carbapenem-Resistant Enterobacterales (CRE) and Carbapenem-Resistant Pseudomonas aeruginosa (CRPA), are common causes of infections in intensive care units (ICUs) in Italy.
Objective: This prospective observational study evaluated the epidemiology, management, microbiological characterization, and outcomes of hospital-acquired CRE or CRPA infections treated in selected ICUs in Italy.
Methods: The study included patients with hospital-acquired infections due to CRE and CRPA treated in 20 ICUs from June 2021 to February 2023.
