House Mice in the Atlantic Region: Genetic Signals of Their Human Transport.

Background/objectives: The colonization history of house mice reflects the maritime history of humans that passively transported them worldwide. We investigated western house mouse colonization in the Atlantic region through studies of mitochondrial D-loop DNA sequences from modern specimens.

Methods: We assembled a dataset of 758 haplotypes derived from 2765 mice from 47 countries/oceanic archipelagos (a combination of new and published data).

Whole genome sequence-based association analysis of African American individuals with bipolar disorder and schizophrenia.

In studies of individuals of primarily European genetic ancestry, common and low-frequency variants and rare coding variants have been found to be associated with the risk of bipolar disorder (BD) and schizophrenia (SZ). However, less is known for individuals of other genetic ancestries or the role of rare non-coding variants in BD and SZ risk. We performed whole genome sequencing of African American individuals: 1,598 with BD, 3,295 with SZ, and 2,651 unaffected controls (InPSYght study).

Occurrence of Taenia species and Toxoplasma gondii in pigs slaughtered in Bujumbura city, Kayanza and Ngozi provinces, Burundi.

Background: Taenia spp. and Toxoplasma gondii are foodborne parasites affecting humans and pigs. The magnitude of the burden of these parasites in pigs in Burundi is not known.

Unveiling the Colors of Mustelids: A Historical Review on the Emergence of Chromatic Disorders and Their Ecological Effects in Mustelids Worldwide with Report of the First Case of Erythrism in Eira barbara (Carnivora, Mustelidae).

Mustelidae is the largest and most diverse family within the order Carnivora, encompasses 65 species and 22 genera, and is widely distributed around the world. Mustelids exhibit a multiplicity of coloration patterns, ranging from darker tones, such as black and brown, to lighter tones, such as pale yellow and white. Anomalous colorations in wild mustelids are occasionally reported, but these records are still poorly discussed in the scientific literature and are often subject to misidentification and/or incorrect terminology.
