Mycotic Keratitis due to Beauveria alba

Cornea, 1984
A 70-year-old white man developed mycotic keratitis following phacoemulsification and intraocular lens implantation. Extensive therapeutic surgery was necessary to control the infection. Beauveria alba, a saprophytic fungus, was cultured and demonstrated in the corneal button by histopathologic examination.

Medical Management of Beauveria bassiana Keratitis

Cornea, 2000
To describe a case of Beauveria bassiana keratitis and to discuss the management of this rare condition.An 82-year-old woman underwent surgical repair of a graft wound dehiscence. Seven months later, shortly after the removal of sutures, the patient developed a fungal keratitis. B. bassiana was identified as the infecting organism.

Heterocaryons chez Beauveria tenella

Mycopathologia, 1977
Differentes methodes pour obtenir des heterocaryons entre mutants auxotrophes ont ete utilisees. Seule la methode de fusion par le polyethylene glycol a donne des heterocayons; ces heterocaryons ont un rapport nucleaire inferieur a 1 et sont instables.

Pigments of the genus Beauveria

Canadian Journal of Botany, 1968
Red coloring substances found in isolates of the imperfect fungus Beauveria were identified as the dibenzoquinone pigment oosporein. Yellow pigments were isolated from both B. bassiana and B. tenella cultures and found to be mixtures of similar compounds. Two types (designated tenellins and bassianins) occurred.

Serological classification of Beauveria bassiana

Journal of Invertebrate Pathology, 1988
Abstract Antigenic properties of blastospores of Beauveria bassiana and Beauveria brongniartii were analyzed by the slide agglutination and reciprocal absorption tests and the existence of at least three serotypes (B 1 , B 2 , and B 3 ) in B. bassiana was demonstrated.

Toxins of the entomophagous fungus Beauveria bassiana

Journal of Invertebrate Pathology, 1968
Abstract The toxic substances produced by submerged cultures of Beauveria bassiana in a medium containing glucose, starch, corn-steep liquor, CaCO3, and NaCl were examined. The high-molecular-weight compounds toxic for Galleria mellonella larvae were separated from the culture filtrate by means of precipitation by ammonium sulfate and desalting on ...

Physiological characteristics and virulence of auxotrophic and morphological mutants of Beauveria Brongniartii (sacc.) petch (= Beauveria tenella)

Mycopathologia, 1985
Various mutants have been obtained of B. brongniartii, a hyphomycete pathogenic for insects. Both one pigment less and two blastospore negative mutants retained their initial virulence. Thus neither the characteristic parasitic blastospore morphology nor the synthesis of the pigment appeared to be required for pathogenesis.

Characterization of Beauveria bassiana isolates from Kyrgyzstan

Journal of Invertebrate Pathology, 2019
We report on the enzootic foci of the insect pathogenic fungus, Beauveria bassiana, found in high meadows in the middle mountain steppes of Kyrgyzstan, at elevations from 1000 m to 2200 m. The growth characteristics of various B. bassiana isolates on different media and as a function of temperature were studied.
