Phylogenetic Analysis of Escherichia coli Isolated from Australian Feedlot Cattle in Comparison to Pig Faecal and Poultry/Human Extraintestinal Isolates

Antibiotics, 2023
The similarity of commensal Escherichia coli isolated from healthy cattle to antimicrobial-resistant bacteria causing extraintestinal infections in humans is not fully understood.

Parasite infections in a social carnivore: Evidence of their fitness consequences and factors modulating infection load [PDF]

, 2019
There are substantial individual differences in parasite composition and infection load in wildlife populations. Few studies have investigated the factors shaping this heterogeneity in large wild mammals or the impact of parasite infections on Darwinian ...

Ecological feedbacks and the evolution of resistance [PDF]

Journal of Animal Ecology, 2009
Summary 1.  The idea that parasites can affect host diversity is pervasive, and the possibility that parasites can increase host diversity is of particular interest. In this review, we focus on diversity in the resistance of hosts to their parasites, and on the different ways in which parasites can increase or decrease this ...

The ecology and evolution of tetracycline resistance [PDF]

Trends in Ecology & Evolution, 1992
The use of tetracycline over the past few decades has been accompanied by a drastic increase in the frequency of tetracycline resistance in a wide range of bacterial species and genera. A diversity of resistance determinants is found in the microbial world, coding for markedly different mechanisms of resistance.

Resilience trinity: safeguarding ecosystem functioning and services across three different time horizons and decision contexts [PDF]

, 2020
Ensuring ecosystem resilience is an intuitive approach to safeguard the functioning of ecosystems and hence the future provisioning of ecosystem services (ES). However, resilience is a multi‐faceted concept that is difficult to operationalize.

Conserved and specific features of Streptococcus pyogenes and Streptococcus agalactiae transcriptional landscapes

BMC Genomics, 2019
Background The human pathogen Streptococcus pyogenes, or group A Streptococcus, is responsible for mild infections to life-threatening diseases. To facilitate the characterization of regulatory networks involved in the adaptation of this pathogen to its ...

Long-Distance Wind-Dispersal of Spores in a Fungal Plant Pathogen: Estimation of Anisotropic Dispersal Kernels from an Extensive Field Experiment [PDF]

, 2014
Given its biological significance, determining the dispersal kernel (i.e., the distribution of dispersal distances) of spore-producing pathogens is essential. Here, we report two field experiments designed to measure disease gradients caused by sexually-

Patient colonization with Phytobacter spp. co-harboring blaIMP-4, blaSHV-12, and mcr-9.1 highlights its role as an under-recognized reservoir of antimicrobial resistance

International Journal of Infectious Diseases
We report two uncommon cases of patient colonization with multidrug-resistant, carbapenemase-encoding Phytobacter species in Ireland. Phytobacter is a recently delineated genus within the Enterobacterales that is commonly misidentified in clinical ...
