Impact of climate- and urbanization-driven environmental change on Aedes aegypti susceptibility to Zika virus
… mosquito infection dynamics. Survival under desiccation stress is correlated with ZIKV infection rates in genetically diverse lines of Ae. aegypti originating from Senegal. Here, we investigated the genetic relationship between desiccation tolerance and ZIKV susceptibility by identifying …

Molecular analysis of the responses of Caenorhabditis elegans (Bristol N2), Panagrolaimus rigidus (AF36) and Panagrolaimus sp. (PS 1579) (Nematoda) to water stress
… and genetic analysis of the responses to water stress in desiccation-tolerant and desiccation-sensitive nematodes. Caenorhabditis elegans, a model organism for the study of development, aging, and cell biology was shown to be a desiccation-sensitive organism that survives relative humidities …

Identification of strains of Rhizobium leguminosarum
… important to understand what effect desiccating stress can have and whether there is natural variation in the ability of individual strains to tolerate such stress. This could inform the development of better commercial inoculants and enable them to persist better in dry soils. Numerous …

The resilience of Polar Collembola to climate change
… than -10 ℃). Survival rates in response to a desiccation stress were also variable among individuals (range: 1.0-13.5 hrs). This indicated that Arctic Collembola may be pre-adapted to a level of climate warming. I also explored the specific relationship between two populations of the Antarctic …

The effects of an invasive species on the structure of native ecosystems
… playing an important role in the north and desiccation stress at the cypris stage controlling populations in the south. A. modestus was the dominant barnacle species within Lough Hyne marine reserve and on artificial structures surveyed in south-west Ireland. Despite this dominance, native …

A proteomic investigation of the rhizomes of the resurrection fern Mohria caffrorum L. (Desv.) in response to desiccation
… information on the mechanisms of vegetative desiccation-tolerance in resurrection plant rhizomes, this work was undertaken to study the mechanisms of desiccation-tolerance in Mohria caffrorum rhizomes. Fronds of this plant have been previously characterized as being desiccation-tolerant in …

Genetic Determinants of Salmonella and Campylobacter Required for In Vitro Fitness
… 14028S (S. Typhimurium) to the mimicked host stressors in vitro conditions. Such as low acidic pH (pH 3) found in the stomach, osmotic (3% NaCl) and short chain fatty acid (SCFAs, 100 mM Propionate) found in intestine, and oxidation (1mM H2O2) and starvation (12-day survival in PBS) found in …

Physiological characterisation of the neonatal meningitic bacterium Cronobacter sakazakii
… MLST analysis, physiological characterisation of stress responses along with genomic analysis associated genes. In the first part of the study, MLST was used to analyse three collections of environmental bacterial isolates. The isolates were from powdered infant formula, milk powder factory …

The Proteomic Responses of Gill Tissue in Tidally and Subtidally-Acclimated Mussel Congeners (Mytilus trossulus and Mytilus galloprovincialis) to Acute Aerial-Emersion Hypoxia
… environments, making it one of the most stressful marine habitats. It is characterized by a 24 hr light: dark cycle and a 12.4 tidal ebb and flow that exposes animals inhabiting this habitat to a wide array of aerial-associated stressors such as changes in temperature, aerial exposure, …

The functional role of root-associated microbiome and metabolome of myrothamnus flabellifolia
… mechanisms these plants employ to adapt during desiccation. Despite this, the role of the microbiome in desiccation tolerance, particularly in resurrection plants, remains a relatively unexplored area. Myrothamnus flabellifolia, a resurrection plant, stands out for its remarkable ability to …

Analysis of the nuclear proteome of the resurrection plant Xerophyta viscosa (Baker) and its response to dehydration stress
… can survive extremes of dehydration (desiccation), down to 5% relative water content (RWC) and resumes full physiological activity within 80 h of rehydration. A thorough understanding of this phenomenon may provide further insight into possible mechanisms for improving drought …

Influence of Physiological State, Prolonged Dry Storage, and Passage through Simulated Digestion on the Survival and Gene Expression of Salmonella enterica sv. Tennessee
… if biofilms will also improve survival to desiccation and gastric stresses. The purpose of this study was to quantify the effect of physiological state (planktonic versus biofilm) and prior exposure to desiccation on Salmonella survival and gene expression after passage through an in-vitro …
