Assessment of Caenorhabditis elegans Competitive Fitness in the Presence of a Bacterial Parasite
Authors:  McKenna. J. Penley and Levi T. Morran, date: 08/20/2018, view: 246, Q&A: 0
Accurate measurements of an organism’s fitness are crucial for measuring evolutionary change. Methods of fitness measurement are most accurate when incorporating an individual’s survival and fecundity, as well as accounting for any ecological ...

Structural Analysis of Bordetella pertussis Biofilms by Confocal Laser Scanning Microscopy
Authors:  Natalia Cattelan, Osvaldo Miguel Yantorno and Rajendar Deora, date: 08/05/2018, view: 268, Q&A: 0
Biofilms are sessile communities of microbial cells embedded in a self-produced or host-derived exopolymeric matrix. Biofilms can both be beneficial or detrimental depending on the surface. Compared to their planktonic counterparts, biofilm cells ...
