Here we report for the first time, a detailed characterization of a variant of the SCCmec element, in a methicillin-resistant Staphylococcus intermedius human isolate. S. intermedius is a coagulase-positive zoonotic microrganism, recently classified as a separate species. In routine clinical laboratory practice, the coagulase production is used as criterion of pathogenicity related to S. aureus, but S. intermedius is frequently misidentified-being mistaken for S. aureus-and consequently its real incidence underestimated. S. intermedius have been found only occasionally in human beings, and methicillin-resistance is very rare for this organism. Even if the genetic element responsible for methicillin-resistance--the mecA gene carried by diverse staphylococcal chromosomal cassettes--has been described in various staphylococcal species, the current literature doesn't report any case of S. intermedius isolate carrying SCCmec-like elements. Our study could be useful to explain the mechanism and routes of transfer of the chromosomal cassette carrying the mec complex, among staphylococci.

Tangier disease is an extremely rare autosomal recessive monogenic disorder caused by mutations in the ATP binding cassette transporter A1 gene (ABCA1). It is characterized by severe deficiency or absence of high-density lipoprotein cholesterol (HDL-C) and apolipoprotein A-1 (ApoA1), with highly variable clinical presentations depending on cholesterol accumulation in macrophages across different tissues. We report a case of a 47-year-old man with very low HDL-C and very high triglyceride levels, initially attributed to the patient's metabolic syndrome, alcohol abuse, and splenomegaly.

Mitochondria derive the majority of their lipids from other organelles through contact sites. These lipids, primarily phosphoglycerolipids, are the main components of mitochondrial membranes. In the cell, neutral lipids like triacylglycerides (TAGs) are stored in lipid droplets, playing an important role in maintaining cellular health.

Increased incidence of Clostridioides difficile infections were documented in Bulgarian hospitals during COVID-19. WGS was performed on 39 isolates from seven hospitals during 2015-2022. Antimicrobial resistance and toxin genes were inferred from genomes.

The Acinetobacter baumannii is a member of the "ESKAPE" bacteria responsible for many serious multidrug-resistant (MDR) illnesses. This bacteria swiftly adapts to environmental cues leading to the emergence of multidrug-resistant variants, particularly in hospital/medical settings. In this work, we have demonstrated the outer membrane protein 33-36 (Omp33-36) porin as a potential therapeutic target in A.

Introduction: Kabuki Syndrome (KS) is a rare genetic disorder characterized by distinctive facial features, intellectual disability, and multiple congenital anomalies. It is caused by pathogenic variants in the and genes. Despite its significant disease burden, there are currently no approved therapies for KS, highlighting the need for advanced research and therapeutic development.
