Physiological responses of Brazilian amphibians to an enzootic infection of the chytrid fungus Batrachochytrium dendrobatidis.

Diseases of Aquatic Organisms, 2016
Pathophysiological effects of clinical chytridiomycosis in amphibians include disorders of cutaneous osmoregulation and disruption of the ability to rehydrate, which can lead to decreased host fitness or mortality.

Host‐feeding preferences of Culex pipiens and its potential significance for flavivirus transmission in the Camargue, France

Medical and Veterinary Entomology, Volume 39, Issue 3, Page 614-625, September 2025.
We identified Culex pipiens bloodmeals at the species level in natural, agricultural and peri‐urban habitats and calculated host preferences based on forage ratios. This analysis showed Passeriformes, and in particular Columba livia, Passer montanus and Turdus sp., to be the preferred Cx. pipiens hosts.

Venezuelan Equine Encephalitis, Peruvian Amazon, 2020

Emerging Infectious Diseases
We screened 1,972 febrile patients from the Peruvian Amazon in 2020–2021 for Venezuelan equine encephalitis virus (VEEV). Neutralizing antibody detection rate was 3.9%; 2 patients were PCR positive.

Borrelia bissettiae sp. nov. and Borrelia californiensis sp. nov. prevail in diverse enzootic transmission cycles

International Journal of Systematic and Evolutionary Microbiology, 2016
Two species of the genus Borrelia, Borrelia bissettiae sp. nov. and Borrelia californiensis sp. nov., were first described by Postic and co-workers on the basis of genetic analyses of several loci.

Oropouche Virus Importation in Southern Brazil and Emerging Concern Calling for Enhanced Public Health Surveillance

Journal of Medical Virology, Volume 97, Issue 8, August 2025.
ABSTRACT Oropouche virus (OROV), an arthropod‐borne virus transmitted by Culicoides paraensis, is an endemic arbovirus that historically circulates mostly in the Amazon basin. Between 2022 and 2024, it reemerged as a more widespread public health concern in South America.

Genetic evidence of enzootic leishmaniasis in a stray canine and Texas mouse from sites in west and central Texas

Memorias do Instituto Oswaldo Cruz
We detected Leishmania mexicana in skin biopsies taken from a stray canine (Canis familiaris) and Texas mouse (Peromyscus attwateri) at two ecologically disparate sites in west and central Texas using polymerase chain reaction (PCR).

Longitudinal monitoring of Culicoides in Belgium between 2007 and 2011: local variation in population dynamics parameters warrant cautious use of monitoring data

Parasites & Vectors, 2018
Background Several European countries suffered important economic losses during the past decade due to the emergence of bluetongue and Schmallenberg viruses. Both are viruses of veterinary importance and are spread by Culicoides spp.

Abundance, Diversity and Phenology of Mosquito Larvae in a Highly Anthropized Wetland: Health and Management Implications of Gándaras de Budiño (NW Spain)

Ecology and Evolution, Volume 15, Issue 7, July 2025.
The natural and anthropized wetland of Gándaras de Budiño (Galicia, Spain) hosts a great number of mosquito species. Culex pipiens s.l. and Culex torrentium pose an emerging risk for West Nile virus transmission. The temporary and polluted waters, as well as the summer and spring seasons, favor the larval proliferation of these vectors.

Exploring the Effects of Giraffe Skin Disease Limb Lesions on Locomotion

Ecology and Evolution, Volume 15, Issue 7, July 2025.
We found that giraffe skin disease lesions altered normal walking gait kinematics largely irrespective of lesion severity or number of limbs affected. Impaired movement due to GSD could negatively impact foraging efficiency, dispersal, and/or predator susceptibility; however, additional research is required to explicitly address these topics.

Triple reassortment increases compatibility among viral ribonucleoprotein genes of contemporary avian and human influenza A viruses.

PLoS Pathogens, 2021
Compatibility among the influenza A virus (IAV) ribonucleoprotein (RNP) genes affects viral replication efficiency and can limit the emergence of novel reassortants, including those with potential pandemic risks.
