A global regulatory system links virulence and antibiotic resistance to envelope homeostasis in Acinetobacter baumannii. [PDF]
PLoS Pathogens, 2018 The nosocomial pathogen Acinetobacter baumannii is a significant threat due to its ability to cause infections refractory to a broad range of antibiotic treatments.

Electron microscopic, genetic and protein expression analyses of Helicobacter acinonychis strains from a Bengal tiger. [PDF]
PLoS ONE, 2013 Colonization by Helicobacter species is commonly noted in many mammals. These infections often remain unrecognized, but can cause severe health complications or more subtle host immune perturbations.

Solitons and Physics of the Lysogenic to Lytic Transition in Enterobacteria Lambda Phage [PDF]
arXiv, 2011 The lambda phage is a paradigm temperate bacteriophage. Its lysogenic and lytic life cycles echo competition between the DNA binding CI and CRO proteins. Here we address the Physics of this transition in terms of an energy function that portrays the backbone as a multi-soliton configuration.

Structural and functional analysis of SleL, a peptidoglycan lysin involved in germination of Bacillus spores. [PDF]
, 2015 A major event in the germination of Bacillus spores concerns hydrolysis of the cortical peptidoglycan that surrounds the spore protoplast, the integrity of which is essential for maintenance of dormancy.

A Lytic Transglycosylase of Neisseria gonorrhoeae Is Involved in Peptidoglycan-Derived Cytotoxin Production [PDF]
Infection and Immunity, 2002 ABSTRACT Neisseria gonorrhoeae releases soluble fragments of peptidoglycan during growth. These molecules are implicated in the pathogenesis of various forms of gonococcal infection. A major peptidoglycan fragment released by gonococci is identical to the tracheal cytotoxin of Bordetella pertussis
