Campylobacter coli bacteremia associated with diarrhea

open access: yesIDCases, 2023
Campylobacter coli (C. coli) is a gram negative, non-spore forming, mobile, curved, or spiral-shaped rod organisms and one of the most common gastrointestinal human pathogens. Campylobacter very rarely causes bacteremia.

Lectures on Elastic Curves and Rods [PDF]

open access: yesAIP Conference Proceedings, 2008
These five lectures constitute a tutorial on the Euler elastica and the Kirchhoff elastic rod. We consider the classical variational problem in Euclidean space and its generalization to Riemannian manifolds. We describe both the Lagrangian and the Hamiltonian formulation of the rod, with the goal of examining the (Liouville‐Arnol'd) integrability.

Morphological change of coiled bacterium Spirosoma linguale with acquisition of β-lactam resistance

open access: yesScientific Reports, 2021
Spirosoma linguale is a gram-negative, coiled bacterium belonging to the family Cytophagaceae. Its coiled morphology is unique in contrast to closely related bacteria belonging to the genus Spirosoma, which have a short, rod-shaped morphology.
