Evaluating the capacity of human gut microorganisms to colonize the zebrafish larvae (Danio rerio) [PDF]

open access: yes, 2018
Indexación: Scopus.In this study we evaluated if zebrafish larvae can be colonized by human gut microorganisms. We tested two strategies: (1) through transplantation of a human fecal microbiota and (2) by successively transplanting aerotolerant anaerobic

Shedding light on bacteria–host interactions with the aid of TnSeq approaches

open access: yesmBio
Bacteria are highly adaptable and grow in diverse niches, where they often interact with eukaryotic organisms. These interactions with different hosts span the entire spectrum from symbiosis to pathogenicity and thus determine the lifestyle of the ...

Japan’s Karafuto Governorate (1905-1945): History and Social Memory

open access: yesRussian Japanology Review, 2019
The history of colonies under the rule of the Japanese Empire in the first half of the 20th century has not been explored well enough so far. For example, the history of Karafuto Governorate (1905-1945), which existed in southern Sakhalin, is covered ...

Pneumococcal surface adhesion A protein (PsaA) interacts with human Annexin A2 on airway epithelial cells

open access: yesVirulence, 2021
Streptococcus pneumoniae (pneumococcus) is a normal colonizer of the human nasopharynx capable of causing serious invasive disease. Since colonization of the nasopharynx is a prerequisite for progression to invasive diseases, the development of future ...

Effects of diversity on community assembly in newly formed pond communities

open access: yesEcosphere, 2016
Theory suggests that in a new habitat, initial levels of genetic or species diversity can influence subsequent community assembly. Nevertheless, empirical investigations of these diversity effects in newly created habitats remain rare at both the genetic

Flexible males, proactive females: increased boldness/exploration damping with time in male but not female colonists

open access: yesRoyal Society Open Science
Individuals colonizing new areas during range expansion encounter challenging and unfamiliar environments, suggesting that colonists should differ in behavioural traits from residents of source populations.

Lower Density and Shorter Duration of Nasopharyngeal Carriage by Pneumococcal Serotype 1 (ST217) May Explain Its Increased Invasiveness over Other Serotypes

open access: yesmBio, 2020
Streptococcus pneumoniae is a frequent colonizer of the human nasopharynx and a major cause of life-threating invasive infections such as pneumonia, meningitis and sepsis.

Photosynthesis under far‐red light—evolutionary adaptations and bioengineering of light‐harvesting complexes

open access: yesFEBS Letters, EarlyView.
Phototrophs evolved light‐harvesting systems adapted for efficient photon capture in habitats enriched in far‐red radiation. A subset of eukaryotic pigment‐binding proteins can absorb far‐red photons via low‐energy chlorophyll states known as red forms.

Epidemiology of Methicillin-resistant Staphylococcus aureus Colonization in Neonates within Neonatal Intensive Care Units: A Systematic Review and Meta-analysis

open access: yesJournal of Global Infectious Diseases
Introduction: Methicillin-resistant Staphylococcus aureus (MRSA) colonization in neonatal intensive care units (NICUs) is a significant global health concern, leading to severe infections, extended hospital stays, and substantial economic burdens on ...
