Phase and Antigenic Variation In Mycoplasmas
Future Microbiology, 2010 With their reduced genome bound by a single membrane, bacteria of the Mycoplasma species represent some of the simplest autonomous life forms. Yet, these minute prokaryotes are able to establish persistent infection in a wide range of hosts, even in the presence of a specific immune response.

Frontiers in Microbiology, 2020 Evolution experiments in the laboratory have focused heavily on model organisms, often to the exclusion of clinically relevant pathogens. The foodborne bacterial pathogen Campylobacter jejuni belongs to a genus whose genomes are small compared to those ...

Variational Hilbert Quantitative Phase Imaging [PDF]
Scientific Reports, 2020 AbstractUtilizing the refractive index as the endogenous contrast agent to noninvasively study transparent cells is a working principle of emerging quantitative phase imaging (QPI). In this contribution, we propose the Variational Hilbert Quantitative Phase Imaging (VHQPI)—end-to-end purely computational add-on module able to improve performance of a ...

Riboregulation in the Major Gastric Pathogen Helicobacter pylori
Frontiers in Microbiology, 2021 Helicobacter pylori is a Gram-negative bacterial pathogen that colonizes the stomach of about half of the human population worldwide. Infection by H.

mSphere, 2017 Streptococcus pneumoniae (pneumococcus) is a leading human pathogen that can cause serious localized and invasive diseases. Pneumococci can undergo a spontaneous and reversible phase variation that is reflected in colony opacity and which allows the ...

mSphere, 2019 Most urinary tract infections (UTIs) are caused by uropathogenic Escherichia coli (UPEC), which depends on an extracellular organelle (type 1 pili) for adherence to bladder cells during infection.

A collective mechanism for phase variation in biofilms [PDF]
Proceedings of the National Academy of Sciences, 2008 Understanding how microbes gather into biofilm communities and maintain diversity remains one of the central questions of microbiology, requiring an understanding of microbes as communal rather then individual organisms. Phase variation plays an integral role in the formation of diverse phenotypes within biofilms.

Pneumococcal Phasevarions Control Multiple Virulence Traits, Including Vaccine Candidate Expression
Microbiology Spectrum, 2022 Streptococcus pneumoniae is the most common cause of bacterial illness worldwide. Current vaccines based on the polysaccharide capsule are only effective against a limited number of the >100 capsular serotypes.
