The consequences of partial clonality on the spatiotemporal genetic structure of the red alga Chondria tumulosa (Ceramiales, Rhodophyta)

Journal of Phycology, EarlyView.
Abstract The relative rates of sexual versus clonal reproduction partition genetic diversity, but the quantification of these rates remains limited in natural populations. This knowledge gap is particularly acute among tropical macroalgae. Chondria tumulosa is a red macroalga that has been documented at high abundance in the three northernmost atolls ...

Phylogeny and Disease Association of Shiga Toxin–producing Escherichia coli O91

Emerging Infectious Diseases, 2009
The diversity and relatedness of 100 Shiga toxin–producing Escherichia coli O91 isolates from different patients were examined by multilocus sequence typing. We identified 10 specific sequence types (ST) and 4 distinct clonal groups.

Genetic, phenotypic, and ecological differentiation indicate a new cryptic and threatened species in the orchid genus Epidendrum from Alcatrazes Island, southeastern Brazil

Journal of Systematics and Evolution, EarlyView.
Epidendrum insularis occurs on the remote Alcatrazes Island in the southeastern Brazilian coast. The description of this new cryptic species was only possible by the joint use of molecular markers, reproductive experiments, flower morphometry, functional traits, and community analysis.

Global and regional landscape of biogeographical diversity of Streptococcus mutans: Epidemiological insight from multilocus sequence typing

International Journal of Medical Microbiology
Streptococcus mutans (S. mutans) is a major cariogenic bacterium. However, its geographic population structure remains poorly characterized. This study included 728 clinical strains collected by our team (339 from Bengbu and 389 from Guangzhou), of which

Molecular characterization and epidemiology of cefoxitin resistance among Enterobacteriaceae lacking inducible chromosomal ampC genes from hospitalized and non-hospitalized patients in Algeria: description of new sequence type in Klebsiella pneumoniae isolates

Brazilian Journal of Infectious Diseases, 2015
In this study, 922 consecutive non-duplicate clinical isolates of Enterobacteriaceae obtained from hospitalized and non-hospitalized patients at Bejaia, Algeria were analyzed for AmpC-type β-lactamases production.

Predictive evolutionary genomics: principles, validation, and practice

New Phytologist, EarlyView.
Summary Climate change and habitat loss are driving rapid evolutionary responses in populations world‐wide, which creates an urgent need for evolutionary forecasting in conservation and agriculture. Such forecasting can be categorized into three time scales: trait‐based models that use multivariate quantitative genetic equations to project correlated ...

Exploring the Genetic Diversity of Candida albicans in Animal Hosts: A One Health Perspective

Zoonoses and Public Health, EarlyView.
ABSTRACT Introduction Candida albicans is an important priority fungal pathogen that commonly colonizes humans and a wide range of animal hosts, although its population structure in wildlife remains poorly explored. Methods In this study, 41 C. albicans isolates obtained from Italian wild animals (European hedgehogs, wolves, foxes, badgers, roe deer ...
