"Clinical Aspects of Chronic Granulomatous Disease in Upper Egypt". Immunol Invest. 2020 Jan 22;:1-13 Authors: El-Mokhtar MA, Salama EH, Fahmy EM, Mohamed ME Abstract Chronic granulomatous disease (CGD) is a rare inherited primary immunodeficiency disorder that affects phagocytes and is characterized by a marked increased susceptibility to severe bacterial and fungal infections. We aimed to describe the clinical presentations of pediatric patients with CGD in Upper Egypt and to identify the defective component of NADPH oxidase. Pediatric patients diagnosed with CGD within one year from January 2018 to January 2019 were enrolled in the study. Patient history, clinical and laboratory investigations were carried out, including nitroblue tetrazolium test and flow cytometry DHR analysis. Infectious microorganisms were isolated from infected sites to identify the causative agents and their resistance profile. A total of 15 patients were diagnosed with CGD. Failure to thrive and lymphadenopathy were the most common presentations. The median age of clinical onset was 1.17 years of age. The most common gene mutations were observed in the CYBA gene. All cases showed pulmonary infections followed by abscesses. Staphylococcus aureus and Klebsiella pneumoniae were the most frequently isolated bacterial pathogens, Aspergillus spp and Candida spp were isolated from fungal infections. 4/15 (26.7%) children died due to severe serious infections. We conclude...

Thus, it is urgent to develop efficient antibacterial agent with excellent wound healing capability. In this research, a two-step strategy was employed for the development of novel chitosan scaffold reinforced by strontium doped TiO2 nanoparticles (CS/Sr-TiO2). The antibacterial activity of CS/Sr-TiO2 against Escherichia coli, and Staphylococcus aureus were evalua...

ConclusionMucormycosis is a rare, but well recognized fungal infection typically spreading by direct tissue invasion or hematogenously after angioinvasion. Few case reports highlight perineurial Mucor spreading and none detail dissemination along peripheral nerves as seen here. In light of the high morbidity and mortality of these infections, the importance of timely diagnosis and thorough imaging investigations including MR neurography is emphasized.

As Iranian bioethanol plants often face the problem of high color content, therefore, an efficient decolorization process is required to determine the quality of effluent so as to meet demanded standards. The existing color in effluent is identified as Melanoidins, which is adsorbed by fungal mycelia or biodegraded. In ...

Therefore, antimicrobial peptides (AMPs) have emerged as a promisingly new group of therapeutic agents for managing infectious diseases. This research was designed to explore the potency of antimicrobial peptides from Omani Juniperus seravschanica plant and their mode of action. The isolated AMPs showed to have inhibitory activity towards pathog...
