() from Zacatecas and Chihuahua Mexico: New Geographical Distribution and Altitude Records.

Adults and immatures of were collected in July and December 2022 at sites of high elevation in the states of Chihuahua (2300 masl) and Zacatecas (2182 and 2595 masl), Mexico, respectively. Mosquitoes were identified morphologically and sequenced for a DNA barcode of the cytochrome c oxidase I (COX1). This is the first distributional record of in Zacatecas and provides evidence of the highest altitude in the Americas, including Mexico.

Canine Distemper Virus: Origins, Mutations, Diagnosis, and Epidemiology in Mexico.

This review provides an overview of the canine distemper virus (CDV), a highly infectious pathogen causing severe disease in domestic dogs and wildlife. It shares genetic similarities with the human measles virus (HMV) in humans and the rinderpest virus (RPV) in cattle. The origin of CDV likely involves a mutation from human measles strains, possibly in the New World, with subsequent transmission to dogs.

Discovery of Novel Viruses in Biting Midges in Chihuahua, Mexico.

Biting midges () are vectors of many pathogens of medical and veterinary importance, but their viromes are poorly characterized compared to certain other hematophagous arthropods, e.g., mosquitoes and ticks.

Mosquito immune cells enhance dengue and Zika virus dissemination in .

Mosquito-borne viruses cause more than 400 million annual infections and place over half of the world's population at risk. Despite this importance, the mechanisms by which arboviruses infect the mosquito host and disseminate to tissues required for transmission are not well understood. Here, we provide evidence that mosquito immune cells, known as hemocytes, play an integral role in the dissemination of dengue virus (DENV) and Zika virus (ZIKV) in the mosquito .

Production of a chimeric flavivirus that contains the major structural glycoprotein genes of T'Ho virus in the genetic background of Zika virus.

T'Ho virus is a poorly characterized orthoflavivirus most closely related to Rocio virus and Ilheus virus, two orthoflaviviruses associated with human disease, suggesting that T'Ho virus could also be a human pathogen. The genome of T'Ho virus has been sequenced but an isolate has never been recovered, impeding its phenotypic characterization. In an attempt to generate recombinant T'Ho virus, the entire viral genome was synthesized as three overlapping DNA fragments, joined by Gibson assembly, and transfected into mosquito cells.
