Bordetella biofilms: a lifestyle leading to persistent infections.
TL;DR: The role of Bordetella factors in biofilm development in vitro and in the mouse respiratory tract is systematically discussed and the implications of biofilms to bacterial persistence and transmission in humans and for the design of new acellular pertussis vaccines are outlined.
Localization of adhesins on the surface of a pathogenic bacterial envelope through atomic force microscopy
Laura Arnal,Gabriel Sebastián Longo,Petar Stupar,Marcos F. Castez,Natalia Cattelan,Roberto Carlos Salvarezza,Osvaldo Yantorno,Sandor Kasas,María Elena Vela +8 more
TL;DR: A force induced reorganization of the adhesin on the surface of the cells, which could explain a reinforced adhesive response under external forces is shown, contributing to the understanding of basic molecular mechanisms used by bacterial pathogens to cause infectious disease.
Adhesin contribution to nanomechanical properties of the virulent Bordetella pertussis envelope.
Laura Arnal,Diego O. Serra,Natalia Cattelan,Marcos F. Castez,Luis Vázquez,Roberto Carlos Salvarezza,Osvaldo Yantorno,María Elena Vela +7 more
TL;DR: A nanoscale stiffness map is built that reveals an inhomogeneous spatial distribution of Young modulus as well as the presence of rigid nanodomains on the cell surface and a nanomechanical properties of the bacterial envelope obtained by AFM force-volume analysis.

Paraburkholderia tropica as a plant-growth–promoting bacterium in barley: characterization of tissues colonization by culture-dependent and -independent techniques for use as an agronomic bioinput
Sabrina Soledad García,Pamela Romina Bernabeu,Santiago Adolfo Vio,Natalia Cattelan,Julia E. García,Mariana Puente,Maria Lina Galar,Claudia Prieto,María Flavia Luna +8 more
TL;DR: Paraburkholderia tropica MTo-293 was characterized as an efficient biofilm-forming and barley-tissue–colonizing bacterium despite the presence of other microorganisms, but root endophytic colonization resulted dependent on the plant-growth system.

The Transcriptional Regulator BpsR Controls the Growth of Bordetella bronchiseptica by Repressing Genes Involved in Nicotinic Acid Degradation.
Manita Guragain,Jamie Jennings-Gee,Natalia Cattelan,Natalia Cattelan,Mary E. Finger,Matt S. Conover,Thomas Hollis,Rajendar Deora +7 more
TL;DR: BpsR, the previously described regulator of biofilm formation and Bps polysaccharide production, controls Bordetella bronchiseptica growth by regulating the expression of genes involved in the degradation of nicotinic acid (NA).
