Steered molecular dynamics simulations of a type IV pilus probe initial stages of a force-induced conformational transition. [PDF]
PLoS Computational Biology, 2013 Type IV pili are long, protein filaments built from a repeating subunit that protrudes from the surface of a wide variety of infectious bacteria. They are implicated in a vast array of functions, ranging from bacterial motility to microcolony formation ...

Cystitis in guinea pigs (Cavia porcellus): Clinical findings and treatment outcomes
Veterinary Record, EarlyView.Abstract Background This retrospective study examined the incidence, diagnostic methods, bacterial isolates, treatments and outcomes associated with cystitis in guinea pigs presented at a single clinic between 2009 and 2022. Methods The clinic's medical records database was reviewed using easyvet software to identify cases eligible for inclusion in the

Nature CommunicationsType IV pili are filamentous appendages found in most bacteria and archaea, where they can support functions such as surface adhesion, DNA uptake, aggregation, and motility. In most bacteria, PilT-family ATPases disassemble adhesion pili, causing them to

Journal of Forensic Sciences, EarlyView.Abstract Postmortem decomposition changes of bodies in aquatic environments may offer valuable insights into the postmortem submergence interval (PMSI) for medicolegal death investigators. However, the effects of immersion on the onset of such changes are poorly understood.

The role of the motility of Methylobacterium in bacterial interactions in drinking water [PDF]
, 2018 Bacterial motility is one important factor that affects biofilm formation. In drinking water there are key bacteria in aggregation, whose biology acts to enhance the formation of biofilms. However, it is unclear whether the motility of these key bacteria

Archaeal type IV pili stabilize Haloferax volcanii biofilms in flow
Current Biology, 2023 AbstractBiofilms represent a prevalent lifestyle of unicellular organism that confers protection to external challenges. The mechanisms by which archaea form biofilms are however not entirely clear.H. volcaniiis an extremely halophilic euryarchaeon that commonly colonizes salt crust surfaces.H.

Beyond the next step: A multi‐criteria generative validation framework for step selection functions
Methods in Ecology and Evolution, EarlyView.Abstract Step‐selection functions (SSFs), typically fitted using step‐selection analysis (SSA) or integrated step‐selection analysis (iSSA) are widely used to infer habitat selection and movement kernels from high‐frequency telemetry data, but most standard validation tools focus on one‐step‐ahead prediction and do not guarantee that fitted models ...

Type IV pili mechanochemically regulate virulence factors in Pseudomonas aeruginosa [PDF]
Proceedings of the National Academy of Sciences, 2015 Significance In their natural environments, bacteria frequently transition from a free-swimming state to a surface-associated state, attached to a substratum. As they encounter a surface, they may initiate developmental programs to optimally colonize this new environment and induce pathways such as virulence.

Structure of the Neisseria meningitidis Type IV pilus
Nature Communications, 2016 Type IV pili are present on a wide range of bacterial pathogens and mediate diverse functions. Here the authors report a high resolution crystal structure of the pilin subunit PilE, and a cryoEM reconstruction of the Type IV pilus filament from N ...
