de la polimerasa (PCR) y secuenciación mediante amplificación genómica de la región espaciadora interna transcrita (ITS-2) del ADN ribosómico, obteniendo Beauveria bassiana con un porcen-taje de similitud de la misma especie en GenBank del 99% (BLAST GU373855.1). Tras su identificación, y aun no habiendo suficientes pruebas que demostraran la infección fúngica, se decidió tratar al paciente con...

BACKGROUND Entomopathogenic fungi such as Beauveria bassiana are considered promising biological control agents for a variety of arthropod pests. Beauveria species, however, have the potential to elicit allergenic reactions in humans, although no specific allergens have been characterized to date. METHODS Four putative allergens were identified within B. bassiana expressed sequence tag (EST) ...

We have established the chemical structure of (+)-bassianolone (3), the antimicrobial compound precursor of cephalosporolides E and F, and that of the furan metabolite 4 from the entomopathogenic fungus Beauveria bassiana.

Beauveria spp. (one Beauveria sp., two B. brongniartii, and 47 B. bassiana) isolated from insects and soil from Kenya and other 16 different countries, were obtained from the CABI Bioscience Genetic Resource Collection. DNA was extracted from the 50 isolates and their genetic variability was investigated using restriction analysis of the internal-transcribed-spacer ribosomal region restriction ...

The aim of this study was to investigate whether S-(-)-10,11-dihydroxyfarnesic acid methyl ester produced by cell subtype Beauveria bassiana CS1029 causes acute toxicity when used for cosmetic purposes by performing an eye irritation test. New Zealand white (NZW) rabbits were treated with a 100 mg/dose of S-(-)-10,11-dihydroxyfarnesic acid methyl ester according to standard procedure guidelines...

Beauveria sinensis sp. nov. was isolated from a larva of Geometridae (Lepidoptera) collected from Tiantangzhai, Anhui province, China. It is characterized by elongated ellipsoidal to cylindrical conidia, solitary conidiogenous cells that are cylindrical or with slightly swollen bases, white to pale pink colony in culture, and small mycelial pellets consisting of curved hyphae. Phylogenetic anal...

The ending of dual nomenclatural systems for pleomorphic fungi in 2011 requires the reconciliation of competing names, ideally linked through culture based or molecular methods. The phylogenetic systematics of Hypocreales and its many genera have received extensive study in the last two decades, however resolution of competing names in Cordycipitaceae has not yet been addressed. Here we present...

Biomass yields and sporulation of Beauveria bassiana was concerned on culture conditions, environmental factors and cultivation method. We optimized the best culture conditions for biomass yields of B. bassiana IBC1201 with the novel "two-stage" cultivation method as well as orthogonal matrix method. Firstly, we cultured spore suspension on the basal medium (sucrose 19.00 g, soy peptone 4.06 g,...

The direct toxicity of insecticidal soap, horticultural oil, Azatin, an extract from the Neem tree containing azadiractin, and BotainiGard, a commercial formulation of the entomopathogenic fungus Beauveria bassiana, was assessed on adults of four species of coccinellids--Hippodamia convergens (Guérin-Ménéville), Coleomegilla maculata (DeGeer), Harmonia axyridis Pallas, and Cryptolaemus montrouz...

The objective of this study was to select strains of Beauveria bassiana for controlling Cosmopolites sordidus (Germ.) in plantain farms (cv. Terra) of the "Recôncavo" and southern regions in the state of Bahia, Brazil. The virulence of 32 B. bassiana isolates against C. sordidus was determined under laboratory conditions. Three isolates (CNPMF 407, CNPMF 218, and CNPMF 416) were selected for ev...
