Canine influenza virus (CIV) subtypes H3N8 and H3N2 are endemic among domestic dog (Canis lupus familiaris) populations in the northeastern US. Infection of free-ranging carnivores with influenza virus has been sporadically reported. Generalist mesocarnivores that exploit anthropogenic, peri-urban habitats share a wide interface with domestic dogs that allows for the transmission of infectious disease. To investigate the potential exposure of free-ranging canids to CIV in Pennsylvania, US, serum samples were obtained from freshly killed coyotes (Canis latrans, n=67), grey foxes (Urocyon cinereoargenteus, n=8), and red foxes (Vulpes vulpes, n=5) from 24 counties. Animals were harvested during the January-February 2017 hunting season. We failed to detect antibodies to CIV subtypes H3N2 and H3N8 by using hemagglutination inhibition assays validated for domestic dogs. Results suggest CIV was not endemic in free-ranging canid populations in Pennsylvania or that prevalence was too low to be detected by our limited sample size. [ABSTRACT FROM AUTHOR]

The article presents research on prevalence of Hepatozoon parasite in wild canid and rodent species from remote areas in North Africa. It discusses research on the dynamics of trophic transmission of the parasite, prevalence in host species cluding African jerboa Jaculus jaculus, greater Egyptian jerboa Jaculus orientalis and golden jackal Canis aureus and implications of this mode of transmission studies in disease ecology and evolution.

The article reports the isolation and identification of the N gene of the rabies virus detected from a young red fox that had the vaccine strain Street Alabama Dufferin (SAD) B19. It mentions the Basic Logical Alignment Search Tool alignment conducted on 589 nucleotides, the determination of virus as identical to the GenBank reference SAD B19 strain, and the two nucleotide modifications identified during sequence analysis of the N and M genes.

The article presents a study which focuses on the importance of recognizing the risk of parasites shed by wild canids to human and domestic animal health. It aims to establish the prevalence of patent infections with Toxocara canis and other parasites in foxes (Vulpes vulpes) and coyotes (Canis latrans) in Prince Edward Island, Canada. It identified parasite species with the use of a sucrose fecal flotation method. It says that the study warrants the attention of public health professionals.

The article reports on a longitudinal epidemiologic survey of the possible role of red foxes from Southeastern France in the natural cycle of Leishmania. Using quantitative polymerase chain reaction (PCR) in screening 92 species, it was found that prevalence of Leishmania infantum infection was 9%. Red foxes may reportedly be considered a bioindicator of parasite circulation in this biotope.
