Background: A stable and reproducible experimental bacterial pneumonia model postintracerebral hemorrhage (ICH) is necessary to help investigating the pathogenesis and novel treatments of Stroke-associated pneumonia (SAP).
Aim: To establish a Gram-negative bacterial pneumonia-complicating ICH rat model and an acute lung injury (ALI)-complicating ICH rat model.
Methods: We established two standardized models of post-ICH pneumonia by nasal inoculation with () or intratracheal inoculation with lipopolysaccharide (LPS).

Green synthesis of metal nanoparticles using plant extracts has emerged as an eco-friendly alternative to conventional methods, offering potential applications in biomedicine and environmental remediation. This study demonstrates the successful biosynthesis of silver nanoparticles (SNPs) and gold nanoparticles (GNPs) using Euphorbia acaulis leaf extract as a reducing and capping agent. The nanoparticles were thoroughly characterized using UV-Vis spectroscopy, HR-SEM, EDX, TEM, AFM, XRD, and FTIR analyses, confirming their successful synthesis and revealing their predominantly spherical morphology with sizes ranging from 1 to 100 nm.

Department of Micrology, College of Medicine, Taif University, Taif, 21944, Egypt.
Foot-and-mouth disease (FMD) continues to pose a significant threat in Egypt, necessitating thorough analyses of FMD virus (FMDV) outbreaks. This study analyzed 144 suspected FMD cases across 52 animal collections during the years 2017-2018 and 2022. Recurrent FMD outbreaks in vaccinated dairy cattle were investigated.

Background And Objective: Multiplex polymerase chain reaction (PCR)-based targeted next-generation sequencing (tNGS) is a promising tool for distinguishing lower respiratory tract infections (LRTIs) in clinical practice, and its detectable pathogen spectrum can cover more than 95% of clinical cases. but there is limited information on systematic evaluation of the clinical use of multiplex PCR-based tNGS (mp-tNGS) in IPA cases. We aim to assess mp-tNGS in bronchoalveolar lavage fluid (BALF) for Aspergillus detection in suspected IPA patients, and to provide a reliable basis for initiating antifungal therapy without microbiological or histopathological evidence.
