AI Article Synopsis
Article Abstract
The antibacterial activity of marine fungi extracts was evaluated by a test of efficiency. The fungi were previously inoculated in Malt Agar (EMA) extract with 50% of seawater and growth for 60 days. Triplicate antibiograms were carried out with the extracts. An ANOVA I with a posteriori Duncan test were applied to the diameters of inhibition zones. The extracts of Aspergillus ochraceus 3MCMC3 and Penicillium citrinum (14) 4MCMC16 present wide spectral antibacterial properties, inhibiting 100% and 80% of the developing germs, especially Pseudomonas aeruginosa 9027. The extract of Penicillium (1) 3MLLC5 had the highest efficiency on this strain; P. aeruginosa 9027 and Escherichia coli 10536 were the most sensitive germs when treated with these extracts. These marine fungi can be an important source of antibacterial secondary metabolites.

A new hydrindane derivative, asperhydrindane A (), along with two known sterol analogues [isocyathisterol () and ganodermasides D ()] were isolated from the mangrove-derived fungus GXIMD 03158 attaching to the mangrove L. The structure of was elucidated based on extensive spectral analysis, HRESIMS, and calculated ECD methods. All compounds were evaluated for antibacterial activity.

The first marine pestivirus, Phocoena pestivirus (PhoPeV), isolated from harbor porpoise, has been recently described. To further characterize this unique pestivirus, its host cell tropism and growth kinetics were determined in different cell lines. In addition, the interaction of PhoPeV with innate immunity in porcine epithelial cells and the role of selected cellular factors involved in the viral entry and RNA replication of PhoPeV were investigated in comparison to closely and distantly related pestiviruses.

Highly pathogenic avian influenza (HPAI) epizootics have caused repeated mass mortality events among wild birds. The effect of the infection is potentially detrimental for a variety of bird species, including the Peregrine Falcon (). The numbers of wintering and breeding Peregrine Falcons in the Netherlands have recently declined.

Globally, forests are constantly threatened by a plethora of disturbances of natural and anthropogenic origin, such as climate change, forest fires, urbanization, and pollution. Besides the most common stressors, during the last few years, Portuguese forests have been impacted by severe decline phenomena caused by invasive pathogens, many of which belong to the genus . The genus includes a large number of species that are invading forest ecosystems worldwide, chiefly as a consequence of global trade and human activities.
