Staphylococcus spp. play an important role in the etiology of bovine mastitis. Staphylococcus aureus is considered the most relevant species due to the production of virulence factors such as slime, which is required for biofilm formation. This study aimed to evaluate biofilm production and its possible relation to beta-lactamic resistance in 20 S. aureus isolates from bovine mastitic milk. The...

ABSTRACT Bacterial spot caused by Xanthomonas spp. (X. vesicatoria, X. euvesicatoria pv. euvesicatoria, perforans, and hortorum gardneri) may result in significant losses for tomato crops. Simonkolleite nanoparticles (SK-NPs) has been indicated as a novel approach plant disease control. The objective of this work was to evaluate SK-NPs (ZnOCl, ZnOCl:Ag, ZnOCl:Cu at different concentrations) the...

Bacterial cells exhibit a wide variety of shapes. Recent results indicate that the characteristic crescent shape of Caulobacter crescentus depends upon an inter-mediate filament-like protein that localizes to the concave side of the cell.

microbe-associated molecular patterns (mamps) play key roles as activators of the innate immune response in animals and, analogously, as elicitors of defense responses in plants. however, there are not much investigations concerning their real importance in plant resistance against pathogens. here we used derivatives of flagellin and ef-tu as two well-known mamps against some important fungal a...
