Junio 18, Aceptado: Maize is the major crop in Mexico according to the annually cultivated area and its per capita consumption.

The losses on grain production are associated with handling during field harvest, storage, transportation, and processing for either human or animal consumption.

The maize grain has antibioiss pests associated such as bacteria, insects and fungi that can cause damage. Among them, the fungal genus Aspergillus and particularly species A. Currently, Mexican regulations establish maximum limits of aflatoxins in cereal products, but other mycotoxins are excluded. The production conditions for maize in tropical and subtropical environments, particulary in northeastern Mexico, favor infections by toxigen fungi.

Symbiosis – Wikipedia

Therefore, it is necessary to identify and implement strategies that can reduce grain fungal contamination. Such measures will individual or together gradually reduce damage caused by potentially toxigenic fungi to the maize plant and ultimately to the consumer in Mexico. Here, we present an overview of current research about aflatoxigenic fungi in maize in Mexico, their implications on both human and cattle health, the tools phytopathology, genetics of both the host and the pathogen, biochemistry, among others to study this problem antibioiss well as those strategies for integrated management in order to date and to weight all data published until now, and then, establish essential points for further research.

Una de las particularidades de las especies de Aspergillus es su capacidad para producir micotoxinas, en este caso, aflatoxinas AF. Las aflatoxinas G 1 y G 2 se producen por A.

Meaning of “antibiosis” in the Spanish dictionary

Otra toxina producida por A. En contraste, especies como A. La especie productora de aflatoxinas que causa mayores contaminaciones es A.

El genoma de A. Un aspecto importante es que A. Por su parte, Montes et al. De las 41 muestras analizadas, Por su parte, Bucio et al.

Recientes estudios con microarreglos revelan que el genoma de A. Finalmente, Criseo et al. Las aflatoxinas exhiben baja solubilidad en agua, pero son solubles en cloroformo, soluciones acuosas de metano, acetonitrilo o acetona, debido a que los cristales de aflatoxinas no tienen las mismas propiedades de la aflatoxinas naturales.

Implicaciones en salud humana y animal. Resultados semejantes a nivel molecular se reportan en pacientes de Senegal Coursaget et al. Estrategias de manejo integrado. Las concentraciones mayores correspondieron a AFB 1 Este punto es de importancia: Sin embargo esta estrategia es relativamente costosa.

Aunado a lo anterior existen restricciones en el uso de plaguicidas dadas las regulaciones ambientales. Por su parte, Gao et al. Ello lleva a considerar esta estrategia como una alternativa promisoria en el manejo de aflatoxinas. Cada bolsa puede almacenar unas ton de grano.
