Knowledge of the obligate intracellular bacteria from the Chlamydiaceae family has increased significantly in recent years. Not only new chlamydia species, such as Chlamydia avium or C. buteonis in birds have been described, but also known chlamydia in new host species, such as C. psittaci in...

The ongoing coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has caused a large global outbreak. The reports of domestic animals' infection with SARS-CoV-2 raise concerns about the virus's longer-lasting spread, the establishment of a new...

Waddycephalus is an understudied genus of pentastomids native to Australia and south-east Asia. The genus was recognized in 1922 but there has been little research on these pentastomid tongue worms over the last century. A few observations suggest a complex life cycle through 3 trophic levels. We...

With emerging diseases on the rise, there is an urgent need to identify and understand novel mechanisms of prophylactic protection in vertebrate hosts. Inducing resistance against emerging pathogens through prophylaxis is an ideal management strategy that may impact pathogens and their...

Naive multi-host communities include species that may differentially maintain, transmit and amplify novel pathogens; therefore, we expect species to fill distinct roles during infectious disease emergence. Characterizing these roles in wildlife communities is challenging because most disease...

The raccoon (Procyon lotor) is a North American half-bear that is present in much of Europe and Asia as a result of both accidental and planned releases. In Europe, raccoons were introduced primarily as a source of fur for the fur industry. In the 1930s, raccoons were released into the wild in...

To investigate animal reservoirs of monkeypox virus in Nigeria, we sampled 240 rodents during 2018-2019. Molecular (real-time PCR) and serologic (IgM) evidence indicated orthopoxvirus infections, but presence of monkeypox virus was not confirmed. These results can be used to develop public health...

In a "One Health" perspective, the global rise of drug-resistant bacterial infections in human medicine has been the major driver for limiting unnecessary use of antibiotics in veterinary medicine during the last 50 years. In France, national action plans set up early in 2010 in veterinary medicine ...

Experimental approaches are among the most powerful tools available to biologists, yet in many disciplines their results have been questioned due to an underrepresentation of female animal subjects. In parasitology, experiments are crucial to understand host-parasite interactions, parasite...

This special issue includes 30 articles that discuss behavior and chemical ecology, development and life history, myiasis and forensics, risk assessment and economic impact, morphology and systematics, vector control and pest management, host interactions and transmission, and vector-borne diseases.
