Influence of Bacillus amyloliquefaciens subsp. plantarum IMV B-7404 strain exometabolites on phenylalanine ammonia-lyase (PAL, EC 4.3.1.24) activity in winter wheat seedlings has been studied. A significant increase of PAL activity at 4-6 hours after treatment of plant roots with Bacillus amyloliquefaciens subsp. plantarum IMVB-7404 strain exometabolites and in case of leaves infection with Bip...

Seed borne mycoflora associated with ten commercial varieties of wheat viz. Blue silver, Faisalabad 85, Manthar-3, Pak 81, Parwaz 94, Pirsabaq 2005, Punjnad-1, Sariab-92, Sh-2002 and Wafaq-2001 was investigated through standard blotter paper and agar plate method by using Mann-Whitney U test. At least eleven fungal genera were recovered from seeds. The most frequently isolated fungi were Bipola...

Allergic fungal sinusitis (AFS) is a non-invasive form of allergic sinusitis, resulting from the IgE-mediated hypersensitivity reaction to fungal antigen in atopic individuals. It was first described in 1983 by Katzenstein.1 It usually follows a slow, non-aggressive course, and a wide variety of fungal agents have been implicated, with the vast majority belonging to the Dematiaceae family, such...

A total of 33 taxa of scaled chrysophytes were observed from 50 localities in and around the delta region of the Parana River, situated in the subtropics of Argentina. The study sites were divided into five groups based on their physical and chemical characteristics and location within the delta complex. The five groups included waterbodies situated on the delta, channels of the river, tributar...

Ophiobolin A (OP-A), a fungal sesterterpene from Bipolaris oryzae, was recently shown to have anti-glioma activity. We show here that OP-A induces paraptosis-like cell death accompanied by dilation of the endoplasmic reticulum (ER) in glioma cells, and that CHOP-mediated ER stress plays a critical role in this process. OP-A-induced ER-derived dilation and cell death were found to be independent...

Antifungal activity of Bacillus coagulans creates the possibility to use this microorganism in biological control of fungal plant pathogens. Activity of Bacillus coagulans (No 6), isolated from lupine compost, against seven pathogenic species of indicator fungi: Bipolaris sorokiniana, Trichothecium roseum, Rhizoctonia solani, Sclerotinia sclerotiorum, Fusatium oxysporum, Fusarium solani and Fus...

Cancer patients, especially stem cell transplantation recipients and patients with leukemia, constitute a high-risk group for the development of life-threatening systemic fungal infections. Candidiasis represents the most commonly reported fungal infection in cancer patients. Candidemia alone is associated with a mortality rate above 50% in this patient population. Even more challenging than th...
