TL;DR: In this article, the authors evaluated SARS-CoV-2-specific antibody responses after Sputnik V vaccination of healthcare workers in Argentina, measuring IgG anti-spike titers and neutralizing capacity after one and two doses in a cohort of naive or previously infected volunteers.
Journal ArticleDOI
Adhesins of Brucella: Their Roles in the Interaction with the Host

TL;DR: Adhesin-based vaccines may be useful to prevent brucellosis, as intranasal immunization in mice with BtaF conferred high levels of protection against oral challenge with B. suis.
Journal ArticleDOI
Longitudinal Study after Sputnik V Vaccination Shows Durable SARS-CoV-2 Neutralizing Antibodies and Reduced Viral Variant Escape to Neutralization over Time

TL;DR: It is found that while anti-spike antibodies wane over time, the neutralizing capacity to viral variants of concern and local variants of interest is maintained within 4 months of vaccination.
Journal ArticleDOI
MapB, the Brucella suis TamB homologue, is involved in cell envelope biogenesis, cell division and virulence
Magalí G. Bialer,Verónica Ruiz-Ranwez,Gabriela Sycz,Silvia M. Estein,Daniela Marta Russo,Silvia Altabe,Rodrigo Sieira,Angeles Zorreguieta,Angeles Zorreguieta +8 more
TL;DR: The results indicate that the role of B. suis TamB homologue is not restricted to participating in the translocation of autotransporters across the OM but that it is essential for OM stability and protein composition and that It is involved in cell envelope biogenesis, a process that is inherently coordinated with cell division.
Journal ArticleDOI
Combinatorial control of adhesion of Brucella abortus 2308 to host cells by transcriptional rewiring of the trimeric autotransporter btaE gene.
Rodrigo Sieira,Magalí G. Bialer,Mara S. Roset,Verónica Ruiz-Ranwez,Tomás Langer,Gastón Maximiliano Arocena,Estefania Mancini,Angeles Zorreguieta +7 more
TL;DR: Analysis of BtaE promoter sequences of different species indicated that sequences upstream of btaE display high variability probably associated to intrinsic promoter structural features, which may serve as a substrate for reciprocal selection during co‐evolution between this pathogen and its mammalian host.
