Severe COVID-19 patients complicated with aspergillosis are increasingly reported. We present a histopathological proven case of fatal COVID-19-associated pulmonary aspergillosis (CAPA), due to Aspergillus flavus. This report and existing published literature indicate diagnostic challenges and poor outcomes of CAPA in ICU patients.

Most African research reports on the frequent aflatoxin contamination of various foodstuffs, with few reports giving details of the Aspergillus species present in these commodities. Numerous research works provide evidence of the ability of fungi to grow, thrive, and interact with other crop species and focus on the fact that these processes are largely affected by climatic variables. As opposed to the attention directed to the above-mentioned themes, information on the biodiversity of Aspergillus species in maize in most African countries, including South Africa, is lacking.

The increasing global demand for food and the adverse environmental impacts of excessive agrochemical use highlights the urgent need for sustainable and scalable seed treatment technologies. This paper reports a novel photothermal seed coating (QC@SCCNTs) with high biocompatibility, exceptional photothermal efficiency, and notable reusability, serving as an effective alternative to conventional chemical treatments. The coating consists of sericin-functionalized carboxylated carbon nanotubes (SCCNTs) electrostatically complexed with quaternary ammonium chitosan (QC), forming a composite film (QS film).

species play an important role in agriculture and human health, however their detection, distribution and research in Saudi Arabia have not yet been fully described. For this reason, the objective of this study was to review the progress, places where research is being carried out and its long-range strategies in Saudi Arabia over the last 54 years. Applying advanced bibliometric processes, we analyzed a 520 scientific articles recorded a 108 different species from 275 diverse environments.

Background: Chronic pulmonary aspergillosis (CPA) is most commonly caused by Aspergillus fumigatus (AF-CPA). Serum A. fumigatus-IgG, a pivotal investigation for diagnosing CPA, misses 10%-15% of CPA cases.

Ustiloxin analogs, including ustiloxins and phomopsins, are a group of cyclopeptide mycotoxins produced by fungi. They are a 13-membered macrocyclic ring and an ether linkage between tyrosine and isoleucine as the core structure. They are ribosomally synthesized and post-translationally modified peptides.
