Los Hongos en la salud y la enfermedad. Parte I.

Los hongos son organismos eucariontes que tienen nutrición absortiva, con presencia en los más variados ambientes y sustratos. Han sido parte de la historia del hombre y su desarrollo, siendo útiles tanto en la alimentación como en la medicina, producción de enzimas, actividad industri...

Physiological response of Cucurbita pepo var. pepo mycorrhized by Sonoran desert native arbuscular fungi to drought and salinity stresses

Braz. j. microbiol; 49 (1), 2018
ABSTRACT Plants response to symbiosis with arbuscular mycorrhizal fungi (AMF) under water stress is important to agriculture. Under abiotic stress conditions native fungi are more effective than exotics in improving plant growth and water status. Mycorrhization efficiency is related to soil fungi develop...

Chromoblastomycosis: tissue modifications during itraconazole treatment

An. bras. dermatol; 92 (4), 2017
Abstract: Background: Histological and mycological changes during itraconazole use have not been totally established in chromoblastomycosis. Objectives: To evaluate tissue modifications in chromoblastomycosis carriers under itraconazole treatment. Methods: A histological retrospective study of 20 case...

Potential for biocontrol of melanized fungi by actinobacteria isolated from intertidal region of Ilha Do Mel, Paraná, Brazil

Braz. j. microbiol; 48 (1), 2017
Abstract Actinobacteria occur in many environments and have the capacity to produce secondary metabolites with antibiotic potential. Identification and taxonomy of actinobacteria that produce antimicrobial substances is essential for the screening of new compounds, and sequencing of the 16S region of rib...

Infectivity of housefly, Musca domestica (Diptera: Muscidae) to different entomopathogenic fungi

Braz. j. microbiol; 47 (4), 2016
Abstract The housefly Musca domestica is a worldwide insect pest that acts as a vector for many pathogenic diseases in both people and animals. The present study was conducted to evaluate the virulence of different local isolates of Beauveria bassiana, Metarhizium anisopliae and Isaria fumosorosea on M. ...

Is the emergence of fungal resistance to medical triazoles related to their use in the agroecosystems? A mini review

Braz. j. microbiol; 47 (4), 2016
Abstract Triazole fungicides are used broadly for the control of infectious diseases of both humans and plants. The surge in resistance to triazoles among pathogenic populations is an emergent issue both in agriculture and medicine. The non-rational use of fungicides with site-specific modes of action, s...

Detección de manganeso peroxidasa y otras exoenzimas en 4 aislamientos de Geastrum (Geastrales) en cultivo puro
Detection of manganese peroxidase and other exoenzymes in four isolates of Geastrum (Geastrales) in pure culture

Rev. argent. microbiol; 48 (4), 2016
Knowledge regarding the enzymatic machinery of fungi is decisive to understand their ecological role. The species of the genus Geastrum are known to grow extremely slowly in pure culture, which makes it difficult to evaluate physiological parameters such as enzyme activity. Qualitative assays were perfor...

Bases bioquímicas de la tolerancia al estrés osmótico en hongos fitopatógenos: el caso de Macrophomina phaseolina (Tassi) Goid
Biochemical basis of tolerance to osmotic stress in phytopathogenic fungus: The case of Macrophomina phaseolina (Tassi) Goid

Rev. argent. microbiol; 48 (4), 2016
El hongo Macrophomina phaseolina (Tassi) Goid., agente causal de la enfermedad denominada «pudrición carbonosa», provoca pérdidas significativas en la producción de cultivos como maíz, sorgo, soya y frijol en México. Este hongo, parásito facultativo, muestra amplia capacidad de adaptación a ambi...

Differences in the fly-load of Haematobia irritans (Diptera: Muscidae) on cattle is modified by endophyte infection of pastures

Electron. j. biotechnol; 16 (5), 2013
Background: The horn fly, Haematobia irritans, is an obligate bloodsucking ectoparasite of pastured cattle and is a major pest of livestock production in North and South America and Europe. In this study, we investigated the potential to use cattle pastures, infected with non-toxic, "friendly" fungal-end...
