Introduction Climate change forms one of the most dangerous problems that disturb earth today. It not only devastates environment but also affects biodiversity living organisms, including fungi. Macrophomina phaseolina (Tassi) Goid. is pervasive and destructive soil-borne fungus threatens food security, so predicting its current future distribution will aid in following emergence new regions taking precautionary measures to control it. Methods Throughout this work, there are about 324...

Mycoremediation is one of the most attractive, eco-friendly, and sustainable methods to mitigate toxic effects heavy metals. This study aimed determine mycoremediation capacity metallophilic fungi isolated from heavy-metal-contaminated soil containing a high Fe(III) concentration (118.40 mg/kg). Four common fungal strains were isolated, including Curvularia lunata, Fusarium equiseti, Penicillium pinophilum, Trichoderma harzianum. These exposed gradually increasing concentrations 100, 200,...

Fungi were used as one of the most common bioremediation methods. From this perspective, our study highlights optimization Alizarin Red S (ARS) dye adsorption performance for sodium alginate (SA) by using fungus Aspergillus terreus (A. terreus) to form a composite bead and possibility its reusability. This was accomplished mixing SA with different ratios biomass powder A. terreus, including 0%, 10%, 20%, 30%, 40%, beads terreus/SA-0%, terreus/SA-10%, terreus/SA-20%, terreus/SA-30%,...

Solanum tuberosum L. possesses economic properties and can host endophytic mycoflora. A total of 19 fungi were identified via morphological molecular methods. Among them, Trichoderma harzianum was the core-group fungus with a relative frequency 36.7%. In preliminary antimicrobial assay, all test pathogens inhibited by Alternaria tenuissima, Penicillium pinophilum rubens maximum inhibition zone 26 mm minimum 11 using agar-plug method. All isolated produced amylase, while cellulase tyrosinase...

ABSTRACT: Background: Hospital acquired infections caused by multi-drug resistant organisms are a significant health risk in Trauma and Surgical Intensive Care Units (TICU SICU), leading to increased morbidity, mortality, healthcare costs. The rise of multidrug-resistant (MDR) exacerbates these challenges, making effective infection control antimicrobial stewardship critical for improving patient outcomes. Objective: This study aimed investigate the microbial epidemiology prevalence SICU) at...

Nosocomial infections are more prevalent in the Intensive Care Unit (ICU) than other hospital departments. This study aimed to elucidate epidemiology and characteristics of ICU-acquired infections, with a focus on impact various risk factors. retrospectively analyzed data from 174 ICU patients admitted between December 2022 November 2023 Beni Suef Hospital, Suef, Egypt. The primary was bacterial including their incidence, causative organisms, infection sites. Additionally, identify factors...
