Seasonal Patterns of Mpox Index Cases, Africa, 1970-2021.

Across 133 confirmed mpox zoonotic index cases reported during 1970-2021 in Africa, cases occurred year-round near the equator, where climate is consistent. However, in tropical regions of the northern hemisphere under a dry/wet season cycle, cases occurred seasonally. Our findings further support the seasonality of mpox zoonotic transmission risk.

Identifying the Most Probable Mammal Reservoir Hosts for Monkeypox Virus Based on Ecological Niche Comparisons.

Previous human cases or epidemics have suggested that Monkeypox virus (MPXV) can be transmitted through contact with animals of African rainforests. Although MPXV has been identified in many mammal species, most are likely secondary hosts, and the reservoir host has yet to be discovered. In this study, we provide the full list of African mammal genera (and species) in which MPXV was previously detected, and predict the geographic distributions of all species of these genera based on museum specimens and an ecological niche modelling (ENM) method.

Draft genome of the lowland anoa (Bubalus depressicornis) and comparison with buffalo genome assemblies (Bovidae, Bubalina).

Genomic data for wild species of the genus Bubalus (Asian buffaloes) are still lacking while several whole genomes are currently available for domestic water buffaloes. To address this, we sequenced the genome of a wild endangered dwarf buffalo, the lowland anoa (Bubalus depressicornis), produced a draft genome assembly and made comparison to published buffalo genomes. The lowland anoa genome assembly was 2.

Inferring the ecological niche of bat viruses closely related to SARS-CoV-2 using phylogeographic analyses of Rhinolophus species.

The Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2) is the causal agent of the coronavirus disease 2019 (COVID-19) pandemic. To date, viruses closely related to SARS-CoV-2 have been reported in four bat species: Rhinolophus acuminatus, Rhinolophus affinis, Rhinolophus malayanus, and Rhinolophus shameli. Here, we analysed 343 sequences of the mitochondrial cytochrome c oxidase subunit 1 gene (CO1) from georeferenced bats of the four Rhinolophus species identified as reservoirs of viruses closely related to SARS-CoV-2.

Genomic history of human monkey pox infections in the Central African Republic between 2001 and 2018.

Monkeypox is an emerging infectious disease, which has a clinical presentation similar to smallpox. In the two past decades, Central Africa has seen an increase in the frequency of cases, with many monkeypox virus (MPXV) isolates detected in the Democratic Republic of Congo (DRC) and the Central African Republic (CAR). To date, no complete MPXV viral genome has been published from the human cases identified in the CAR.

The genome of the lowland anoa (Bubalus depressicornis) illuminates the origin of river and swamp buffalo.

Two types of domestic water buffalo are currently recognized: the river buffalo from the Indian subcontinent and Mediterranean countries and the swamp buffalo from China and Southeast Asia. To test the hypothesis of two separate species of water buffalo, we sequenced the genome of the lowland anoa, Bubalus depressicornis, which is a dwarf wild buffalo endemic to Sulawesi, and two genomes of swamp buffalo, and made comparisons with 12 additional genomes. Three genomic data sets were constructed to infer phylogenetic relationships: the mitochondrial genome (15,468 bp; maternal transmission), two concatenated Y-chromosomal genes, AMELY and DDX3Y (20,036 bp; paternal transmission), and a selection of 30 nuclear genes representing all cattle chromosomes (364,887 bp; biparental transmission).

Haplotype diversity in the mitochondrial genome of the Egyptian river buffalo ().

Here, we sequenced the complete mitochondrial genome of 29 Egyptian river buffaloes collected in two breeding stations of Egypt. The genome is 16,357-16,359 base pairs in length and contains the 37 genes found in a typical mammalian genome. The overall base composition is A: 33.
