Rectification of Swimming Bacteria and Self Driven Particle Systems by Arrays of Asymmetric Barriers [PDF]

Phys. Rev. Lett. 101, 018102 (2008), 2007
We show that the recent experimental observation of the rectification of swimming bacteria in a system with an array of asymmetric barriers occurs due to the ballistic component of the bacteria trajectories introduced by the bacterial "motor." Each bacteria selects a random direction for motion and then moves in this direction for a fixed period of ...

Two mice models for transferability of zoonotic bacteria via tick vector

Acta virologica, 2017
Spotted fever and typhus-related diseases caused by rickettsiae, Lyme borreliosis induced by spirochetes from Borrelia burgdorferii sensu lato complex, and Q fever evoked by Coxiella burnetii, are important zoonoses occurring worldwide. In order to study the pathogenesis of these infections, the efficacy of vaccines from the perspective of protection ...

ZOONOTIC PARASITES AND MICROMAMMALS IN THE YUCATAN PENINSULA, MEXICO: CONTRIBUTIONS OF THE CCBA-UADY

Tropical and Subtropical Agroecosystems, 2021
Background. Micromammals are reservoirs of zoonotic parasites such as viruses, bacteria, protozoans and helminths. Objective. To present a review of the published literature on the study of zoonotic (or potential zoonotic) parasites of micromammals in ...

Formalin‐fixed paraffin‐embedded (FFPE) samples help to investigate transcriptomic responses in wildlife disease

Molecular Ecology Resources, EarlyView., 2023
Abstract Infectious diseases impact numerous organisms. Knowledge of host‐pathogen interactions and host responses to infection is crucial for conservation and management. Obtaining this knowledge quickly is made increasingly possible by a variety of genomic approaches, yet, for many species the bottleneck to understanding this, remains access to ...

O-Antigen Diversification Masks Identification of Highly Pathogenic Shiga Toxin-Producing Escherichia coli O104:H4-Like Strains

Microbiology Spectrum, 2023
Shiga toxin-producing Escherichia coli (STEC) can give rise to a range of clinical outcomes from diarrhea to the life-threatening systemic condition hemolytic-uremic syndrome (HUS).

Swimming statistics of cargo-loaded single bacteria [PDF]

arXiv, 2020
Burgeoning interest in the area of bacteria-powered micro robotic systems prompted us to study the dynamics of cargo transport by single bacteria. In this paper, we have studied the swimming behaviour of oil-droplets attached as a cargo to the cell bodies of single bacteria.

Effect of motility on the transport of bacteria populations through a porous medium [PDF]

Phys. Rev. Fluids 4, 013102 (2019), 2018
The role of activity on the hydrodynamic dispersion of bacteria in a model porous medium is studied by tracking thousands of bacteria in a microfluidic chip containing randomly placed pillars. We first evaluate the spreading dynamics of two populations of motile and non-motile bacteria injected at different flow rates.

The Induction and Characterization of a Potential Rough‐Type Brucella Vaccine Candidate Strain RA343, and Its Safety, Protective Efficacy in Mouse and Guinea Pig Models

Animal Research and One Health, EarlyView.
Brucellosis is a zoonotic disease caused by Brucella spp. which seriously jeopardize the health and safety of animals and human beings. In this study, a genetically stable Brucella rough RA343 strain was obtained by cross‐induction. The virulence and protective efficacy of RA343 were subsequently assessed. Overall, the RA343 strain is a promising novel

Bacteria colonies modify their shear and compressive mechanical properties in response to different growth substrates [PDF]

arXiv, 2023
Bacteria build multicellular communities termed biofilms, which are often encased in a self-secreted extracellular matrix that gives the community mechanical strength and protection against harsh chemicals. How bacteria assemble distinct multicellular structures in response to different environmental conditions remains incompletely understood. Here, we
