Leaf spots and root rots are major fungal diseases in Camptotheca acuminata that limit cultivation of the plant for camptothecin (CPT), a promising anticancer and antiviral alkaloid. Bioassays showed that pure CPT and flavonoids (trifolin and hyperoside) isolated from Camptotheca effectively control fungal pathogens in vitro, including Alternaria alternata, Epicoccum nigrum, Pestalotia guepinii...

Four hundred bacterial isolates were isolated from rhizosphere of some plants collected from Egypt and screened for production of chitinase enzyme. Only four isolates designated MS1, MS2, MS3 and MS4 were the most potent chitinolytic bacterial species. SDS-PAGE analysis of vegetative and sporulated cells of the four isolates revealed that the protein profile of the four isolates were different ...

This paper deals with a case study of conformance testing and interoperability testing of ATM Adaptation Layer type 3/4 (AAL 3/4) implementations. A set of conformance test purposes for AAL 3/4 sublayers is developped. The implementation of these test purposes is analysed using the transverse conformance test method and the interoperability test method. This analysis leads to the identiication ...

The antifungal activity of zinc oxide (ZnO) and magnesium oxide (MgO) nanoparticles prepared by bio-safe method was evaluated for Alternaria alternate, Fusarium oxysporum, Rhizopus stolonifer and Mucor plumbeus. It was observed from the study that all the nanoparticles at different concentrations brought about significant inhibition in the germination of spores of Alternaria alternata, Fusarium...

BACKGROUND : Fungal allergens are ubiquitous; however, little progress has been made understanding fungal allergenic material removal from indoor environments. PURPOSE : We investigated removal of environmental allergenic material derived from Alternaria and Cladosporium using sodium hypochlorite in vivo and in vitro. METHODS : Freeze dried allergen extract from Alternaria alternata and Cla...

Biocontrol is considered as an effective alternative to the application of agrochemicals, which are harmful environment, human, and animal health. In this study, twenty-six strains actinomycetes were isolated from rhizospheric arid soil halophyte Atriplex halimus L. ῾Guettaf’ in Biskra province, Algeria. The six isolates that have inhibited at least three phytopathogenic fungi among five tested...

The ability of Bacillus subtilis, strain ALICA to produce three mycolytic enzymes (chitinase, β-1,3-glucanase, and protease), was carried out by the chemical standard methods. Bacillus subtilis ALICA was screened based on their antifungal activity in dual plate assay and cell-free culture filtrate (25%) against five different phytopathogenic fungi Alternaria alternata, Macrophomina sp., Colleto...

Alternariosis is a fungal infection usually described in immunodeficient patients. We report a case of cutaneous alternariosis in a renal transplant recipient caused by Alternaria alternata. The patient was treated with intralesional amphothericin B and surgical excision of one non-responding lesion was performed.
