The appearance of Candida albicans in three patients made physicians investigate an outbreak. Outbreak description and microbiologic screening: Case 1 developed C. albicans in the placenta culture and in the blood culture carried out on the 8th day of birth. Four days after this candidemia, C. albicans was recovered in a catheter tip of a second neonate (case 2) and finally five days later other newborn (case 3) developed C. albicans in the hemoculture. After that, the hands of all caregivers as well as case 3's incubator, case 1's mother, and from all nine neonates in the unit were studied with swabs. A wet mount was done to all swabs and then they were cultured in Chromagar Candida and SDA. All C. albicans were studied by RAPD. RAPD study showed that C. albicans recovered from placenta and blood cultures of case 1, the catheter tip of case 2 and the blood culture of case 3, resulted to be identical and these yeasts were related to the C. albicans from the mouth of case 1 mother and the mouth of another colonized newborn. C. albicans was not found in the others swabs. The isolations of identical C. albicans allowed to suppose the horizontal transmission from the case 1, that had acquired it congenitally. Not only isolation of unusual Candida species would be an alert. Despite patients' personal factors to justify a fungal infection, the recovery of C. albicans in a short period of time should warn physicians about the possibility of a horizontal transmission.

The study examines the chemical composition and antimicrobial properties of petroleum ether and hydro-methanolic extracts of Achillea santolina(A. santolina) from Algeria. Chemical profiling was performed using High-Performance Liquid Chromatography with Diode Array Detection (HPLC-DAD) for the hydro-methanolic extract and Gas Chromatography-Mass Spectrometry (GC-MS) for the petroleum ether extract.

Innovations in nanostructured surfaces have found a practical place in the medical area with use in implant materials for post-operative infection prevention. These textured surfaces should be dual purpose: (1) bactericidal on contact and (2) resistant to biofilm formation over prolonged periods. Here, hydrothermally etched titanium surfaces were tested against two highly antimicrobial resistant microbial species, methicillin-resistant and .

Inborn errors of immunity (IEI) disorders, formerly primary immune deficiency diseases, are a heterogeneous group of disorders with variable hereditary transitions, clinical manifestations, complications and varying disease severity. Many of the clinical symptoms, signs and complications in IEI patients can be attributed to inflammatory and immune dysregulatory processes due to loss of microbial diversity (dysbiosis). For example, in common variable immunodeficiency patients, the diversity of bacteria, but not fungi, in the gut microbiota has been found to be reduced and significantly altered.

This study investigates the optical, mechanical, and antimicrobial properties of polypropylene (PP) fibers enhanced with titanium dioxide (TiO) and zinc oxide (ZnO) nanoparticles. Using a Mach-Zehnder interferometric system, we examined the refractive indices, birefringence, and opto-mechanical behavior of blank PP, PP/TiO, and PP/ZnO nanocomposite fibers under various conditions, including different polarization orientations and during cold drawing processes. The 2D Fourier transform algorithm is employed to analyze interferometric data, enabling precise measurements of refractive index profiles and birefringence.

The current comprehensive study showcases a meticulous synthesis of novel class of α-benzilmonoxime thiocarbohydrazide (BMOTC) derivatives, and manifesting their multifaceted potential as antibacterial, antifungal, and anticancer agents. The synthesis of target compounds was performed in three phases using literature methods. In the first step, benzilmonoxime is synthesized using benzil and hydroxyl amine hydrochloride, followed by benzilmonoxime imine using thiocarbohydrazide.
