Article Synopsis
- The study explores host specificity in parasites, particularly focusing on the relationship between single-host (specialist) and multiple-host (generalist) parasites using the sucking lice Polyplax serrata and its rodent hosts Apodemus.
- Findings reveal that the S lineage of lice, which exclusively inhabits Apodemus flavicollis, shows higher prevalence and intensity on its specific host compared to the more generalist N lineage that can inhabit multiple Apodemus species.
- The research suggests that the "choice" of the parasite, rather than host accessibility or interspecific competition, primarily influences prevalence, and discusses how historical geographic distribution may explain differences in parasitic strategies, while unexpected fitness drops in hybrids remain unresolved.
Sucking lice of the parvorder Anoplura are permanent ectoparasites with specific lifestyle and highly derived features. Currently, genomic data are only available for a single species, the human louse Pediculus humanus. Here, we present genomes of two distinct lineages, with different host spectra, of a rodent louse Polyplax serrata.

A total of 377 (23.3%) birds representing 15 species were parasitized by 26 species of chewing lice of 12 genera.

It is one of the most prominent genetic contributors to type 1 diabetes mellitus outside the HLA region, and prevalence of its risk variants is subject to enormous geographic variability. Here, we address the genetic background of patients with type 1 diabetes mellitus of Armenian descent.

Wolbachia supergroup F is a particularly interesting clade as it gave rise to symbionts of both arthropods and nematodes, and some of its members are obligate mutualists. Investigations on evolutionary transitions among the different symbiotic stages have been hampered by a lack of the known diversity and genomic data for the supergroup F members.
