There is a global trend toward intensive livestock breeding, which tends to increase the microbial load in environment as well presence of volatile compounds and dust that can cause health issues. Cattle major producer Escherichiacoli (E. coli), group foodborne bacteria associated with severe human diseases, Neuquén province Argentina has one highest rates uremic hemolytic syndrome incidence wo...
That the adenyl lipoate (AMP-lipoate) is the product of activation of lipoate was demonstrated by using the apopyruvate dehydrogenase system of Streptococcus jaecalis as well as Escherichiacoli. Pyruvate dismutation assay was used to demonstrate the activation of apoenzyme with either a mixture of ATP and lipoate or adenyl lipoate alone. That an active intermediate was formed was demonstrated b...
Single particle cryo-electron microscopy (cryo-EM) is an emerging powerful tool for structural studies of macromolecular assemblies (i.e., protein complexes and viruses). Although single particle cryo-EM requires less concentrated and smaller amounts of samples than X-ray crystallography, it remains challenging to study specimens that are low-abundance, low-yield, or short-lived. The recent dev...
Aminopeptidase H11 present in the surface of intestine microvilli in Haemonchus contortus was identified as the most effective antigen candidate. However, its recombinant forms produced in Escherichiacoli, insect cells and yeast could not provide promising protection against H. contortus challenge, probably due to the inappropriate glycosylation and/or conformational folding. Herein, partial H1...
A DNA microarray was developed to detect plasmid-mediated antimicrobial resistance (AR) and virulence factor (VF) genes in clinical isolates of Enterobacteriaceae and non-Enterobacteriaceae. The array was validated with the following bacterial species: Escherichiacoli (n=17); Klebsiellapneumoniae (n=3); Enterobacter spp. (n=6); Acinetobacter genospecies 3 (n=1); Acinetobacterbaumannii (n=1); Ps...
Functional amyloids are important structural and functional components of many biofilms, yet our knowledge of these fascinating polymers is limited to a few examples for which the native amyloids have been isolated in pure form. Isolation of the functional amyloids from other cell components represents a major bottleneck in the search for new functional amyloid systems. Here we present a label-...
