Bipolaris australiensis is recorded as an opportunistic pathogen of humans. The fungus was recovered from a biopsy specimen of skin taken from an area of viral vesicular dermatitis on the scalp. Hyphal elements of B. australiensis were seen in the tissues. The taxonomy of the genera Bipolaris, Drechslera, Exserohilum and Helminthosporium is discussed with particular reference to published case reports.

Rhazya stricta, a perennial shrub native to the Middle East and South Asia, has been used in traditional medicine for various therapeutic purposes, including antimicrobial action. The current study aimed to compare the antifungal properties of 96% and 50% ethanolic extracts of R. stricta leaves and their biogenic silver nanoparticles (AgNPs).

One of the most promising, non-toxic, and biocompatible developments for many biological activities is the green synthesis of nanoparticles from plants. In this work, we investigated the antifungal activity of silver nanoparticles (AgNPs) biosynthesized from Rhazya stricta aqueous extract against several plant pathogenic fungi. UV-visible spectroscopy, Zeta potential analysis, Fourier-transform infrared spectroscopy (FTIR), and transmitted electron microscopy (TEM) were used to analyze the biosynthesized AgNPs.

The search for natural therapeutic agents has intensified due to their potential to treat various diseases. Bioactive secondary metabolites from endophytes offer high therapeutic profiles and can be mass-produced after optimizing medium parameters and purification. This investigation aimed to maximize crude pigmented secondary metabolite (CPSM) production from Curvularia australiensis FC2AP by optimizing fermentation conditions statistically.

The endophytic fungi that reside inside medicinal plants have the potential to produce various pharmaco-potential bioactive compounds. The endophytic fungi , and were isolated from different medicinal plants. The GC-MS analysis of intra- and extracellular products of endophytic fungi revealed the presence of various bioactive metabolites, such as Anthracene, Brallobarbital, Benzo [h] quinolone, Ethylacridine, 2-Ethylacridine, Cyclotrisiloxane, 5 methyl 2 phenylindolizine, and 1,4-Cyclohexadien-1-one, etc.
