Comparative analysis of Wolbachia maternal transmission and localization in host ovaries

The paper examines how temperature affects Wolbachia maternal transmission and localization across diverse strains and hosts.

Rapid host switching of Wolbachia and even more rapid turnover of their phages and incompatibility-causing loci

The paper quantifies the rapid host switching and molecular evolution of Wolbachia and their associated phages and incompatibility genes across insect species.

Aedes albopictus is present in the lowlands of southern Zambia

This paper confirms the presence of Ae. albopictus in rural areas of southern Zambia using DNA barcoding and reports its population dynamics over time.

A simulation framework for modeling the within-patient evolutionary dynamics of SARS-CoV-2

This study develops a simulation framework to model SARS-CoV-2 evolutionary dynamics within patients, identifying plausible models with severe infection bottlenecks and high rates of deleterious mutations.

Distinct Wolbachia localization patterns in oocytes of diverse host species reveal multiple strategies of maternal transmission

The paper identifies three distinct Wolbachia localization patterns in Drosophila oocytes, revealing strategies for maternal transmission through germline and somatic routes.

Hidden endosymbionts: A male-killer concealed by another endosymbiont and a nuclear suppressor

The paper identifies a male-killing Wolbachia strain in Drosophila pseudotakahashii, hidden by a cytoplasmic incompatibility Wolbachia and a nuclear suppressor, revealing complexities in endosymbiont detection and host interactions.

Patterns of and processes shaping population structure and introgression among recently differentiated Drosophila melanogaster populations

The paper examines population structure and introgression in Drosophila melanogaster, finding cryptic diversity and polygenic mate choice in Subtropical Africa.

Male age and Wolbachia dynamics: Investigating how fast and why bacterial densities and cytoplasmic incompatibility strengths vary

The paper investigates how quickly and why Wolbachia-induced cytoplasmic incompatibility (CI) strength declines with male age in two Drosophila species, finding different patterns in Wolbachia density and CI gene expression.

Postzygotic isolation is stronger between sympatric species of three divergent taxa

The paper compares postzygotic and premating reproductive isolation across sympatric species pairs in Drosophila, lepidopterans, and toads, finding stronger postzygotic isolation and divergence time-dependent patterns.

Wolbachia in the spittlebug Prosapia ignipectus: Variable infection frequencies, but no apparent effect on host reproductive isolation

The paper investigates Wolbachia infection frequencies and effects on reproductive isolation in spittlebug populations, finding high but variable frequencies and no apparent impact on reproductive isolation.

Pervasive effects of Wolbachia on host activity

This study investigates how 14 Wolbachia strains affect the locomotor activity of nine Drosophila species, finding that Wolbachia alter activity in six genotypes, with effects varying by host sex and Wolbachia strain.

Divergent effects of Wolbachia on host temperature preference

This study investigates how different Wolbachia strains affect host temperature preference in Drosophila species and finds divergent effects that may influence bacterial transmission.

Environmental and genetic contributions to imperfect wMel-like Wolbachia transmission and frequency variation

The paper investigates factors influencing wMel-like Wolbachia frequency variation in D. yakuba and D. santomea on Sao Tome, finding that temperature affects transmission and fitness, while CI and spatial variation play roles in frequency dynamics.

Dissemination routes of the carbapenem resistance plasmid pOXA-48 in a hospital setting

This study characterizes the dissemination routes of the carbapenem resistance plasmid pOXA-48 in a hospital setting using mechanistic models and genomic data.

Introgressive and horizontal acquisition of Wolbachia by Drosophila yakuba-clade hosts and horizontal transfer of incompatibility loci between distantly related Wolbachia

The paper investigates Wolbachia acquisition modes in Drosophila yakuba-clade hosts, finding introgression and horizontal transfer of incompatibility loci between Wolbachia strains.

Loss of cytoplasmic incompatibility and minimal fecundity effects explain relatively low Wolbachia frequencies in Drosophila mauritiana

The paper investigates Wolbachia variant wMau in Drosophila mauritiana, finding no cytoplasmic incompatibility or significant fecundity benefits, explaining its low infection frequencies.
