Screening for Q Fever during Other Bacterial Endocarditis in Endemic Areas: Our Experience with Three Patients

Case Reports in Infectious Diseases, 2019
Endocarditis is not a usual manifestation of acute Q fever. There is an ongoing debate about the need to screen patients for valvular diseases after acute Q fever.

Porphyromonas gingivalis GroEL exacerbates orthotopic allograft transplantation vasculopathy via impairment of endothelial cell function

Molecular Oral Microbiology, EarlyView.
Abstract Orthotopic allograft transplantation (OAT) is a significant approach to addressing organ failure. However, persistent immune responses to the allograft affect chronic rejection, which induces OAT vasculopathy (OATV) and organ failure. Porphyromonas gingivalis can infiltrate remote organs via the bloodstream, thereby intensifying the severity ...

Bacterial evolution and the Bak-Sneppen model [PDF]

arXiv, 2001
Recently, Lenski et al \cite{Elena,Lenski,Travisano} have carried out several experiments on bacterial evolution. Their findings support the theory of punctuated equilibrium in biological evolution. They have further quantified the relative contributions of adaptation, chance and history to bacterial evolution.

Prevalence of Post‐Operative Infections Related to Third Molar Surgery at an Australian University Teaching Clinic: A 5‐Year Retrospective Study

Oral Surgery, EarlyView.
ABSTRACT Aim To assess the prevalence of post‐operative infection related to surgical third molar extractions at a university teaching hospital. The secondary outcome was to investigate risk factors relating to post‐operative infections, including the use of prophylactic antibiotics.

Analysis of bacterial population growth using extended logistic growth model with distributed delay [PDF]

arXiv, 2018
In the present work, we develop a delayed Logistic growth model to study the effects of decontamination on the bacterial population in the ambient environment. Using the linear stability analysis, we study different case scenarios, where bacterial population may establish at the positive equilibrium or go extinct due to increased decontamination.

Antibacterial Siderophores of Pandoraea Pathogens and Their Impact on the Diseased Lung Microbiota

Angewandte Chemie, Volume 137, Issue 24, June 10, 2025.
Genome mining of environmental and pathogenic Pandoraea species identified a conserved NRPS gene cluster and led to the discovery of novel siderophores, pandorabactins, which exert their antibacterial activity by depleting iron from competitors. Bioinformatic analysis of sputum from cystic fibrosis patients coupled with bioassays indicates that ...

Bacterial tracking of motile algae assisted by algal cell's vorticity field [PDF]

arXiv, 2008
Previously published experimental work by other authors has shown that certain motile marine bacteria are able to track free swimming algae by executing a zigzag path and steering toward the algae at each turn. Here, we propose that the apparent steering behaviour could be a hydrodynamic effect, whereby an algal cell's vorticity and strain-rate fields ...

Quantitative Aspects, Engineering and Optimization of Bacterial Sensor Systems [PDF]

arXiv
Bacterial sensor systems can be used for the detection and measurement of molecular signal concentrations. The dynamics of the sensor directly depend on the biological properties of the bacterial sensor cells; manipulation of these features in the wet lab enables the engineering and optimization of the bacterial sensor kinetics.

Bacterial cooperation leads to heteroresistance [PDF]

arXiv, 2017
By challenging E. coli with sublethal norfloxacin for 10 days, Henry Lee and James Collins suggests the bacterial altruism leads to the population-wide resistance. By detailedly analyzing experiment data, we suggest that bacterial cooperation leads to population-wide resistance under norfloxacin pressure and simultaneously propose the bacteria shield ...
