Antimicrobial activity in methanolic extracts of several plant species from northern Argentina.
Thirty-nine native plant species were collected from the provinces of Chaco and Formosa, in northern Argentina, and were screened for antimicrobial activity, finding that some extracts were able to reduce the initial number of viable counts by at least one order of magnitude in 10 hours, indicating the possible presence of bactericidal components.

Outbreak of Ataxia in Pigs Associated With Consumption of Piquillín (Condalia microphylla)
Results of this investigation indicate that C microphylla toxicosis can affect pigs under natural conditions and should be included in the differential diagnosis for porcine ataxia and leukomyelopathy in regions where the plant grows. Expand

The method was applied to 15 tall fescue samples with varying degrees of fungal infection, and ergovaline was identified in all contaminated samples with endophyte infection above 15%. Expand
Antifungal activity of Parastrephia quadrangularis (Meyen) Cabrera extracts against Fusarium verticillioides
The aim of the present study was to describe the antifungal activity of extracts of Parastrephia quadrangularis, a species from northern Argentina, against Fusarium verticillioides M7075. Expand
In Vitro Antifungal Activity of Peltophorum dubium (Spreng.) Taub. extracts against Aspergillus flavus
The antifungal activity of extracts of Peltophorum dubium, a species from northern Argentina (Oriental Chaco), against A. flavus is described and hyphae treated with the extracts stained blue with Evans blue showed alterations in the membrane and/or cell wall, allowing the dye income. Expand
Suppression of spore germination and aflatoxin biosynthesis in Aspergillus parasiticus during and after exposure to high levels of phosphine
Results strongly suggest that exposure to PH3 levels of 1000 ppm or higher could bring about persistent metabolic changes in surviving Aspergillus organisms. Expand
Zearalenone content in animal fodder samples in relation to weather conditions in Colonia Benítez, northeastern Argentina
The high concentration of ZEA found in many of the forage samples collected in July 2012 was preceded by autumn weather conditions that were exceptionally conducive to plant stress, likely favoured the sharp increase in ZEA content in these pastures when compared to the other two seasons. Expand
