The genus Otodectes Canestrini 1894, comprises an unique species, Otodectes cynotis (Hering, 1838), that is responsible for the 'ear mange' in terrestrial carnivores worldwide. Here we report its occurrence in four Brazilian host species from the southeastern region, based on records from Carnivora in the Acari Collection of the Butantan Institute, São Paulo state (IBSP). We also register a case report of a crab-eating fox, Cerdocyon thous L. 1758 found parasitized by this mite species.

Examination of the host-associated microbiome in wildlife can provide critical insights into the eco-evolutionary factors driving species diversification and response to disease. This is particularly relevant for isolated populations lacking genomic variation, a phenomenon that is increasingly common as human activities create habitat 'islands' for wildlife. Here, we characterised the gut and otic microbial communities of one such species: Channel Island foxes (Urocyon littoralis).

Article Synopsis
- Otodectes cynotis is a contagious ear mite causing ear infections in ferrets, and this study examines the effectiveness and safety of the medication lotilaner for treating infestations.
- Eleven ferrets were treated with oral lotilaner, showing significant reduction in mite populations and related symptoms after 28 and 56 days without any reported side effects.
- Owner satisfaction was high, with a notable improvement in the quality of life for both ferrets and their caregivers, indicating lotilaner is a safe and effective treatment option.

Article Synopsis
- Understanding the role of parasites in wildlife conservation is essential, yet studying ectoparasites in elusive species like the European wildcat poses challenges, particularly with live animals.
- In a study involving 131 deceased wildcats in Germany, a significant 84% were found infested with ectoparasites, with ticks being the most common, affecting 72.5% of the specimens.
- Despite the variety of ectoparasites identified, including fleas and mites, the overall health of the wildcats appeared unimpaired, suggesting that these infestations may not have a major negative impact on their populations.

This study was conducted to evaluate the prevalence of otitis externa (OE) in cats using cytology, direct otoscopic examination, and parasitological examination through swabs and curettage, and to compare the accuracy between collection methods for parasitological examination. Direct otoscopic evaluation of the external auditory canal (right and left), swabs for cytological examination of the external auditory canal, and collection of cerumen for parasitological examination through swabs and curettage of 137 cats from a veterinary hospital care were conducted between March 2021 and March 2022. The influences of age, sex, habitat, street access, and the presence of fleas on OE were evaluated.
