“…The pathognomonic histopathological features of straelensiosis, including pseudoepitheliomatous follicular hyperplasia and abundant perifollicular mucinosis (Le Net et al 2002, Seixas et al 2006, Ramirez et al 2009) were noted in the present cases. A blood-packed mass of irregular squamous epithelial cells with surrounding tissue neovascularisation was noted in one case.…”

“…Albeit, it is noteworthy that other investigators proposed that remission of clinical signs occurs regardless of the treatment protocol, corresponding to the larva detaching from the stylostome upon completion of feeding (Fain and Le Net , Seixas et al . ).…”

“…Straelensia cynotis was shown to cause a distinctive nodular dermatitis in hunting and outdoors dogs in France, Portugal and Spain (Fain & Le Net 2000, Le Net et al 2002, Seixas et al 2006, Ramirez et al 2009. The biology and life cycle of this newly-recognised parasite is currently unknown, but the dogs' lifestyle seemingly has a major role in this accidental infection, as the disease occurs in rural and hunting dogs (Le Net et al 2002, Ramirez et al 2009).…”

Straelensiosis is uncommonly described outside Europe. This report describes straelensiosis in two cats and in ten dogs diagnosed with the disease outside Europe. Both cats displayed erythematous macules or nodules on the abdominal skin. One cat was extremely pruritic, while in the other the lesions were incidental findings when the cat was presented for neutering. The mites were noted in skin scrapings in both cats and histopathologically in one cat. All dogs showed a general distribution of papules, and intense pruritus was noted in six dogs. The diagnosis in all dogs was based on histopathology. Treatment of the animals in this study varied, and among the various administrated treatments, amitraz showed promising results.

“…The mites attach themselves to the skin and make a stylostome, a channel through which salivary enzymes are injected and digested tissue fluids are withdrawn (Ginn et al 2007). Although lesions associated with trombiculid mite infestations are usually mild, some authors reported grossly apparent skin lesions in wild and domestic mammals (Lowenstine et al 1979;O'Callaghan et al 1994;Little et al 1997;Cunningham et al 2001;Seixas et al 2006). We report a case of dermatitis caused by trombiculid mite infestation in an Amami rabbit (Pentalagus furnessi), an endangered leporid that lives only on two islands (Amami-Oshima Island and Tokunoshima Island) of the Ryukyu Archipelago, Japan.…”

We read with interest the case report by Seixas F, Travassos P, Pinto ML et al . Dermatitis in a dog induced by Straelensia cynotis ( Veterinary Dermatology 2006, 17, 81-84), 1 in which they described one dog with a highly pruritic, papular and crusted dermatitis induced by Straelensia cynotis in Portugal. The response to the treatment in that case with systemic ivermectins and oral antibiotic therapy was poor and the dog was euthanized. We are writing to document a similar case of dermatitis without pruritus in one dog with a good prognosis without treatment and long-term follow up. 2 In September 2002, a 4-year-old male wire-haired dachshund (9 kg) presented to Hospital Ars Veterinaria with a 2-week history of erythematous papules. These lesions measured less than 1 mm in diameter and were localized to the frontal, periocular, periauricular, cervical, dorsal and lumbar regions; they did not appear to bother the patient and were nonpruritic. The clinical examination was otherwise normal. The dog lived in the city of Barcelona but had visited a rural area in La Bisbal (north-east of Spain, approximately 40 km from the French border) 14 days before showing the first lesions. The initial treatment included a benzoyl peroxide shampoo once a day (Paxcutol, Virbac Laboratories SA, Carros, France) and amoxycillin/clavulanic acid (Synulox, Pfizer, Alcobendas, Spain) 12 mg kg − 1 twice a day per os for 1 week). After 45 days, the lesions had not improved with the treatment and these had become 2-3-mm-diameter papules (Fig. 1). The lesions were not associated with pruritus or discomfort for the dog. The histopathological examination of lesions from the occipital and dorsal areas showed a basophilic material surrounded by an intensely eosinophilic capsule, consistent with a parasitic structure. The epidermis showed mild hyperplasia with hyperkeratosis and mild inflammatory infiltrate by degenerate neutrophils, some macrophages and eosinophils without mast cells. The diagnosis was parasitic dermatitis caused by S. cynotis (Fig. 2).Our findings are consistent with the description of dermatitis induced by S. cynotis in the south of France by Le Net et al ., 3 although our case did not show discomfort or pruritus, and there were no crusts or suppuration as described by Le Net et al . 3 Our case was otherwise healthy and there was no appetite loss. The hypersensitivity reaction seen in trombiculidiasis is usually not described with S. cynotis , and therefore the lesions are rarely pruritic. 3 Seixas et al . 1 suggested that the pruritus was due to the severe perifollicular infiltration of mast cells, and they did not rule out a secondary bacterial infection. In contrast to Le Net et al . 3 the only case with pruritus was attributed to flea and lice infestation. Figure 1. Papular lesions in the dorsal region.Figure 2. Skin biopsy.
