Abstract
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.

Abstract
INTRODUCTION Otoacariasis is a rare infestation of the ear canal, which affects the quality of life especially in rural areas. Different types of ticks and mites may cause otoacariasis. Although treatment of otoacariasis is simple, diseases transmitted through ticks and mites should be considered during diagnosis and treatment. Both local and systemic signs and symptoms of such diseases should be followed up.A literature review was conducted in PubMed using the following terms: "otoacariasis," "ticks," "mites," and "outer ear canal infestations." Demographic, radiologic, and treatment options were discussed. Treatment hints and pitfalls were also discussed with the literature review. CONCLUSION In this paper, we describe otoacariasis in humans and discuss the appropriate interventions.

Ear Mite Removal in the Santa Catalina Island Fox (Urocyon littoralis catalinae): Controlling Risk Factors for Cancer Development. PLoS One 2015; 10:e0144271.

Abstract
Ear mites (Otodectes cynotis) and ear canal tumors are highly prevalent among federally endangered Island foxes (Urocyon littoralis catalinae) living on Santa Catalina Island off the coast of Southern California. Since studies began in the 1990s, nearly all foxes examined were found to be infected with ear mites, and ceruminous gland tumors (carcinomas and adenomas) were detected in approximately half of all foxes ≥ 4 years of age. We hypothesized that reduction of ear mite infection would reduce otitis externa and ceruminous gland hyperplasia, a risk factor for tumor development. In this study, we conducted a randomized field trial to assess the impact of acaricide treatment on ear mite prevalence and intensity of infection, otitis externa, ceruminous gland hyperplasia, and mite-specific IgG and IgE antibody levels. Treatment was highly effective at eliminating mites and reducing otitis externa and ceruminous gland hyperplasia, and mite-specific IgG antibody levels were significantly lower among uninfected foxes. Ceruminous gland hyperplasia increased in the chronically infected, untreated foxes during the six month study. Our results provide compelling evidence that acaricide treatment is an effective means of reducing ear mites, and that mite removal in turn reduces ear lesions and mite-specific IgG antibody levels in Santa Catalina Island foxes. This study has advanced our understanding of the underlying pathogenesis which results in ceruminous gland tumors, and has helped inform management decisions that impact species conservation.

Abstract
Intra-aural ticks were present in 870 (15.2%) of 5714 patients who reported with ear-related complaints to the ear, nose and throat ward at Ratnapura Hospital, Sabaragamuwa Province, Sri Lanka, from January 2000 to December 2001. A retrospective study of 383 of these otoacariasis cases showed that the majority (70.8%) of surgically-removed ticks were nymphal Amblyomma integrum, together with nymphal and adult Rhipicephalus haemaphysaloides, R. sanguineus, Hyalomma brevipunctata, H. marginatum, and unidentified (damaged) ticks (collectively, 29.2%). Tick infestations peaked during the period November-February. More female than male patients reported with otoacariasis, and more children (aged 0-10 years) and adults (aged >/=21 years) than adolescents. There was no evidence of age-dependent differences in infestation among male and female patients. The tick-infested cases were widespread, spanning 75 km on a north-south axis and 55 km on an east-west axis within Sabaragamuwa Province. The present report represents the largest episode of human otoacariasis recorded in the literature, and may be indicative of a wider, but little-reported, human tick problem in Sri Lanka.
