Vaginal microbial dynamics and pathogen colonization in a humanized microbiota mouse model

open access: yesnpj Biofilms and Microbiomes, 2023
Vaginal microbial composition is associated with differential risk of urogenital infection. Although Lactobacillus spp. are thought to confer protection against infection, the lack of in vivo models resembling the human vaginal microbiota remains a ...

Interrelationship between Candida Colonization, Dentures, and Mucosal Tissue Inflammation in the Pathogenesis of Denture Stomatitis

open access: yesJournal of Pharmacy and Bioallied Sciences, 2023
Despite being common, the pathogenesis of denture stomatitis (DS) is poorly known; thus, this study was conducted to examine the relationship between candida, dentures, and mucosal tissue inflammation. One hundred and twenty edentulous patients wearing a

The fate of the missing spores [PDF]

open access: yes, 2012
It is well-known that many species with small diaspores can disperse far during extended temporal scales (many years). However, studies on short temporal scales usually only cover short distances (in, e.g., bryophytes up to 15 m).

Genetic drift at expanding frontiers promotes gene segregation [PDF]

open access: yes, 2007
Competition between random genetic drift and natural selection plays a central role in evolution: Whereas non-beneficial mutations often prevail in small populations by chance, mutations that sweep through large populations typically confer a selective ...

High-resolution mapping reveals that microniches in the gastric glands control Helicobacter pylori colonization of the stomach

open access: yesPLoS Biology, 2019
Lifelong infection of the gastric mucosa by Helicobacter pylori can lead to peptic ulcers and gastric cancer. However, how the bacteria maintain chronic colonization in the face of constant mucus and epithelial cell turnover in the stomach is unclear ...

Colony Dynamics and Persistence of Ivory Gull Breeding in Canada

open access: yesAvian Conservation and Ecology, 2007
Despite the importance of assessing the viability of small and endangered populations, often few demographic data are available. However, when counts are available from discrete sites, a colony- or site-based approach can be useful. We used recent counts

Bacterial Colonization in the Airways and Intestines of Twin and Singleton Preterm Neonates: A Single-Center Study

open access: yesCanadian Journal of Infectious Diseases and Medical Microbiology, 2023
Limited studies have investigated the microbial colonization of the airways and intestines in preterm neonates. We studied the composition of intestinal and airway bacterial colonies in several preterm twin pairs and singletons to explore the dominant ...
