Fitness costs associated with chemical signaling [PDF]

open access: yesCommunicative & Integrative Biology, 2012
The production, maintenance and transmission of chemical signals often entail costs. Costs can arise, for instance, if signal production depends on the availability of limited nutritional resources or if signal transmission leads to attraction of predators.

A Small Multihost Plasmid Carrying erm(T) Identified in Enterococcus faecalis

open access: yesFrontiers in Veterinary Science, 2022
The aim of this study was to determine the mobile genetic elements involved in the horizontal transfer of erm(T) in Enterococcus faecalis, and its transmission ability in heterologous hosts. A total of 159 erythromycin-resistant enterococci isolates were

The fitness costs of antibiotic resistance mutations [PDF]

open access: yesEvolutionary Applications, 2014
AbstractAntibiotic resistance is increasing in pathogenic microbial populations and is thus a major threat to public health. The fate of a resistance mutation in pathogen populations is determined in part by its fitness. Mutations that suffer little or no fitness cost are more likely to persist in the absence of antibiotic treatment. In this review, we

A comparative analysis of Aedes albopictus and Aedes aegypti subjected to diapause-inducing conditions reveals conserved and divergent aspects associated with diapause, as well as novel genes associated with its onset

open access: yesCurrent Research in Insect Science, 2022
Aedes albopictus and Aedes aegypti are mosquito species that are distributed worldwide and transmit diverse arboviruses of medical importance, such as those causing yellow fever, dengue, chikungunya and Zika. A.

The fitness costs of developmental canalization and plasticity [PDF]

open access: yesJournal of Evolutionary Biology, 2009
AbstractOrganisms are capable of an astonishing repertoire of phenotypic responses to the environment, and these often define important adaptive solutions to heterogeneous and unpredictable conditions. The terms ‘phenotypic plasticity’ and ‘canalization’ indicate whether environmental variation has a large or small effect on the phenotype.

The Cost-effectiveness of Hearing-Aid Fitting in the Netherlands [PDF]

open access: yesArchives of Otolaryngology–Head & Neck Surgery, 2003
To determine the cost-effectiveness of hearing-aid fitting.Cost-effectiveness analysis using a Markov model based on aggregate data and results from a prospective intervention study.The cost-effectiveness study was based in the general community. The prospective study was hospital based, as 85% of the first-time hearing-aid users attend a hospital in ...

Conjugation dynamics depend on both the plasmid acquisition cost and the fitness cost [PDF]

open access: yesMolecular Systems Biology, 2021
Abstract Plasmid conjugation is a major mechanism responsible for the spread of antibiotic resistance. Plasmid fitness costs are known to impact long‐term growth dynamics of microbial populations by providing plasmid‐carrying cells a relative (dis)advantage compared to plasmid‐free counterparts.

Cost-Based Fitness in Conformance Checking

open access: yes2011 Eleventh International Conference on Application of Concurrency to System Design, 2011
Experience in business process analysis shows that operational processes often do not conform to process models. Although classical conformance checking techniques can identify deviations of process executions from predefined models, they may produce inaccurate results due to strong assumptions.

Fitness Cost of Resistance: Impact on Management [PDF]

open access: yes, 2015
Fungicides are important tools for the management of fungal diseases in many crops. But eventually, most fungicides fail because the treated pathogen population evolves resistance to the fungicide. This chapter focuses on how our knowledge of fitness costs associated with resistance informs strategies of fungicide deployment that help to avoid or delay

Fitness benefits in fluoroquinolone-resistant Salmonella Typhi in the absence of antimicrobial pressure

open access: yeseLife, 2013
Fluoroquinolones (FQ) are the recommended antimicrobial treatment for typhoid, a severe systemic infection caused by the bacterium Salmonella enterica serovar Typhi. FQ-resistance mutations in S.
