Introduction: Ecthyma gangrenosum is a cutaneous manifestation of Pseudomonas infections. This condition may be associated with bacteraemia but can also occur in the absence of bacteraemia.
Exegesis: The authors report the case of a 66-year-old woman presented with necrotic ulcerations on the face associated with fever, arthralgia, myalgia, fatigue and neutropenia. Blood cultures and skin cultures were positive for Pseudomonas stutzeri. Her condition improved under appropriate antibiotic therapy. However, the patient further developed clinical and biological symptoms of systemic vasculitis and mixed cryoglubulinemia. Complete healing was finally obtained after a course of corticosteroids.
Conclusion: Ecthyma gangrenosum should be suspected in people who have typical clinical presentation. This disease could sometimes be associated with systemic vasculitis.

Biosynthesis of silver nanoparticles from macroalgae Hormophysa triquetra and investigation of its antibacterial activity and mechanism against pathogenic bacteria.

Environmental Science Program, Department of Biological and Environmental Sciences, College of Arts and Sciences, Qatar University, P. O. Box: 2713, Doha, Qatar.
In this study, brown macroalgae Hormophysta triquetra (HT) collected from the Qatari coast is used to biosynthesize silver nanoparticles (AgNPs) from its aqueous (AQ), chloroform: methanol (MCF), and ethanolic extracts (ET). The NPs are characterized using Transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Gas chromatography/Mass spectrometry (GC/MS) and X-ray photoelectron spectroscopy (XPS). The NPs were evaluated for their antibacterial activities by disc-diffusion method and their minimum inhibitory concentrations (MIC) were assessed.

Increasing industrial pollution and certain hazardous agricultural practices have led to the discharge of heavy toxic metals into the environment. Among different bioremediation techniques, biomineralization is the synthesis of biomineral crystals extracellularly or intracellularly. Several bacteria, such as Bacillus cereus, Pseudomonas stutzeri, Bacillus subtilis, and Lactobacillus sphaericus have been found to induce heavy metal precipitation and mineralization for bioremediation.

The soil environment affected by plant roots and their exudates, termed the rhizosphere, significantly impacts crop health and is an attractive target for engineering desirable agricultural traits. Engineering microbes in the rhizosphere is one approach to improving crop yields that directly minimizes the number of genetic modifications made to plants. Soil microbes have the potential to assist with nutrient acquisition, heat tolerance, and drought response if they can persist in the rhizosphere in the correct numbers.
