Invasive aspergillosis (IA) is an important cause of morbidity and mortality among immunocompromised people. Imaging and specimen tests used in the clinical diagnosis of aspergillosis with weak and indistinct defects leads to delay in the treatment of early aspergillosis patients. The developing molecular techniques provide a new method for the aspergillosis diagnosis. However, the existing methods are complex, time-consuming and may even be potentially hazardous. In this study, we developed a simple and rapid Aspergillus fumigatus spores DNA isolation assay using synthesized zinc oxide (ZnO). ZnO nanoparticles were used to take the place of the traditional commercial lysis buffer. The quality and quantity of the extracted DNA were sufficient for further diagnostics with polymerase chain reaction (PCR) analysis. This method offers easy, green, and economic alternative DNA isolation for the diagnosis of invasive aspergillosis.

Strain NoAH (=KACC 23135=JCM 35999), a novel Gram-negative, motile bacterium with a rod-shaped morphology, was isolated from the zoo animal faecal samples, specifically the long-tailed goral species . The novel bacterial strain grew optimally in a nutrient broth medium under the following conditions: 1-2% (w/v) NaCl, pH 7-8 and 30 °C. The strain NoAH exhibited high tolerance to NaCl, with the ability to tolerate up to 7% (w/v) NaCl.

<b>Background and Objective:</b> It is well documented that Whole Genome Sequencing (WGS) has recently used to explore new resistance patterns and track the dissemination of extensive and pan drug-resistant microbes in healthcare settings. This article explores the link between traumatic infections caused by road traffic accidents (RTAs) leading to coma and the development of chest infections caused by extensively drug-resistant (XDR) <i>Klebsiella pneumoniae</i> and <i>Pseudomonas aeruginosa</i>. <b>Materials and Methods:</b> The study was carried out from March to December 2022 which included a 45-year-old male patient admitted to the ICU of Al Ramadi Teaching Hospitals following a severe RTA that resulted in a TBI and subsequent coma.

Objective: To isolate and quantify cell-free DNA, analysis for p53 mutations, and correlation with tumor burden in women with epithelial ovarian cancer compared with benign and borderline epithelial ovarian tumors.

Methods: In this case-control study, plasma samples of eligible women collected 1 hour before surgery and based on final histopathology, women with epithelial ovarian cancer recruited as cases and borderline, and benign ovarian tumors as controls. Cell-free DNA extracted from plasma serum and quantified using Nanodrop Spectrophotometer.

To ensure high quality of food and water, the identification of traces of pathogens is mandatory. Rapid nucleic acid-based tests shorten traditional detection times while maintaining low detection limits. Challenging is the loss of nucleic acids during necessary purification processes, since elution off solid surfaces is not efficient.

Sıtma, her yıl dünya nüfusunun yarısından fazlası için ciddi bir tehdit oluşturmaya devam etmektedir. Hastalığa neden olan Plasmodium parazitleri, yalnızca insanlarla sınırlı kalmayıp sürüngenlerden kuşlara, memelilerden diğer omurgalılara dek geniş enfeksiyon yelpazesine sahiptir. Plasmodium türleri, çevredeki değişikliklere uyum sağlamalarını sağlayan olağanüstü genetik esnekliğe sahiptir ve bu da onlara sıtma ilaçları gibi tedavi edici maddelere karşı hızla direnç geliştirme ve konakçı özgüllüğünü değiştirme potansiyeli verir.
