Atividade de nucleação de gelo e densidade populacional do patógeno podem ser fatores que contribuem para o progresso da doença mancha branca do milho

A Mancha Branca do Milho (MBM) é uma doença foliar que tem causado perdas apreciáveis, tanto qualitativas como quantitativas para a produção de milho. Seu agente etiológico, a Pantoea ananatis, é uma bactéria epifítica, Gram-negativa formadora de colônia amarela, capaz de formar gelo, mesmo ...

Study of tissue inflammatory response in different mice strains infected by dematiaceous fungi Fonsecaea pedrosoi

An. bras. dermatol; 94 (1), 2019
Abstract: Background: Diseases caused by melanized fungi include mycetoma, chromoblastomycosis and phaeohyphomycosis. This broad clinical spectrum depends on the dynamic interactions between etiologic agent and host. The immune status of the host influences on the development of the disease, as, an exem...

Subcutaneous phaeohyphomycosis due to cladophialophora bantiana: a first case report in an immunocompetent patient in Latin America and a brief literature review

Abstract We report a rare case of subcutaneous phaeohyphomycosis caused by Cladophialophora bantiana in an immunocompetent patient in Amazonas, Brazil. This dematiaceous fungus has been mainly associated with life-threatening infections affecting the central nervous systems of immunosuppressed patients. ...

Combining Ability for Resistance to White Mold in a Diallel Cross of Soybean

Abstract The white mold, caused by Sclerotinia sclerotiorum (Lib.) de Bary, is one of the most important diseases of soybean. The objective of the present work was to evaluate the soybean reaction to the fungus S. sclerotiorum, which causes white mold, in a partial diallel with 50 crosses. The Group I of...

La infección fúngica invasora ha aumentado en frecuencia a lo largo de la última década, y la sinusitis fúngica es cada vez más habitual. Los hongos del género Exserohilum (familia Pleosporaceae, orden Pleosporales) son filamentosos y dematiáceos, de localización ubicua. Se trata de patógenos e...

The improvement of bioactive secondary metabolites accumulation in Rumex gmelini Turcz through co-culture with endophytic fungi

Braz. j. microbiol; 49 (2), 2018
Abstract Aspergillus sp., Fusarium sp., and Ramularia sp. were endophytic fungi isolated from Rumex gmelini Turcz (RGT), all of these three strains could produce some similar bioactive secondary metabolites of their host. However the ability to produce active components degraded significantly after cultu...

Validación de una técnica de Dot blot para la detección de Cercospora kikuchii en plantas de soja

Rev. argent. microbiol; 50 (2), 2018
Cercospora kikuchii, fitopatógeno usual en plantas de soja, ocasiona deterioro en la scosechas. Su identificación precoz y correcta evitaría el uso indebido de plaguicidas y permitiría iniciar un tratamiento adecuado. Una técnica rápida, económica y de fácil ejecución es el Dot blot, capaz de re...

Effects of essential oils from two Lippia species on growth of phytopathogenic fungi

Chemical characterization of the essential oils of two Lippia species by GC-MS and NMR spectroscopy revealed that limonene (84.3%) and β-caryophyllene (6.1%) were the most abundant components in Lippia turbinata while (6S,7S,10S)-trans-davanone (99.1%) predominated in Lippia integrifolia. Antifungal act...

Comparative proteomic analyses of Hyphozyma roseonigra ATCC 20624 in response to sclareol

Braz. j. microbiol; 49 (supl.1), 2018
Abstract Sclareol is an important intermediate for ambroxide synthesis industries. Hyphozyma roseonigra ATCC 20624 was the only reported strain capable of degrading sclareol to the main product of sclareol glycol, which is the precursor of ambroxide. To date, knowledge is lacking about the effects of scl...
