Birds of prey have carnivorous habits, and they have specialized anatomical and physiological characteristics that give them great hunting capacity (Sick, 1997). These characteristics vary depending on the lifestyle of the bird (Tully, Dorrestein, & Jones, 2000). The caracara (Caracara plancus) is a predatory bird that belongs to the Daptriidae Family, which belongs in the Falconiform Order (Cubas, Silva, & Catão-Dias, 2014). It is an opportunistic bird that has omnivorous habits (Sick, 1997), feeds mainly on carrion and arthropods, but it also hunts live prey, such as rodents and lagomorphs (Travaini, Donazar, Ceballos, & Hiraldo, 2001). This species inhabits open fields, occurring from Florida to South America (Sick, 1997). The great egret (Ardea alba) is a pelecaniform bird that belongs to Ardeidae Family (Cubas et al., 2014). They have long pelvic limbs and toes, a thin neck and a long and pointed beak (Sick, 1997). Generally, there is no evident sexual dimorphism and there is a distinction in plumage between young and adults (Cubas et al., 2014). Their diet includes fish, insects, mollusks, crustaceans, amphibians and reptiles

Background The maintenance of marmosets in captivity may trigger various disorders. The objective of this study was to provide a radiographic evaluation of the forelimbs and hind limbs of marmosets rescued from illegal wildlife trade and maintained in captivity. Methods Fourteen marmosets were studied. Results and conclusions Three marmosets were apparently normal. Of the eleven marmosets with radiographic changes in the hind limbs, five had pelvic narrowing and bilateral varus deviation of the femur, with one suggestive of rickets and another of osteomalacia. The other marmosets showed changes such as malunion of acetabular fracture, transtibial amputation, tibial antecurvatum, and knee osteoarthritis. Six marmosets showed alterations in the forelimbs such as radius fracture, scapulohumeral subluxation, and elbow joint incongruence. In conclusion, 78.57% of the marmosets had bone and/or joint changes detected by plain radiography, which were found predominantly in the hind limbs and without impediment to locomotion in captivity.

Hemoparasites are vector-borne parasites that infect wild carnivores worldwide. Since data on hemoparasite infections in Nasua nasua from Brazil are lacking, the aim of this study was to investigate the occurrence of hemoparasites and ectoparasites in N. nasua from different areas of Brazil. Blood samples and ectoparasites from 83 N. nasua were collected in Botucatu, Palmital, and São Paulo municipalities. Samples were screened via microscopy and molecular methods to detect hemoparasites. Tissues from two N. nasua were obtained for histopathological and molecular analyses. All 83 samples were negative for piroplasms on morphological and molecular examination. Thin blood smears of nine animals were positive for Hepatozoon gamonts. The gamonts shared morphological characteristics of Hepatozoon procyonis. Meronts were detected in the liver and spleen tissue of one animal. Twenty-one blood samples and four tissue samples were PCR positive for Hepatozoon sp. The sequences obtained were 97% identical to those of Hepatozoon felis, Hepatozoon ursi, and Hepatozoon sp. Based on searches for similarity and morphology, we identified the sequences as belonging to H. procyonis. This study provides epidemiological data on hemoparasite infections and redescribe H. procyonis based on morphological, morphometrical, and molecular analyses.

Background: Chrysocyon brachyurus is a South American wild canid considered a species near threatened by the International Union for Conservation of Nature and is classified as vulnerable in the National List of Endangered Species. With the increase of the contact between domestic animals, human population and wild animals, there was a greater exposure of the maned wolf to pathogens. Due to the importance of its conservation, the knowledge of emerging infectious diseases that affect this species becomes essential. This report aims to describe the first diagnosed case of dermatophytosis caused by Microsporum canis in a maned wolf.Case: A free-living female maned wolf (Chrysocyon brachyurus), approximately 60 days old, was rescued with presence of alopecia, non-pruritic lesions, one of circular shape located in the nasal plane and the other with signs of scaling and crusts in the region of the left pina. The animal was active, in good general condition and without other significantchanges to clinical examination. Skin scraping was performed for mycological culture of both lesions. Fungal growth on Sabouraud’s agar identified Microsporum canis. Topical therapy with ketoconazole ointment and cleaning of lesions with 0.2% chlorhexidine was instituted. After 20 days of treatment, remission of clinical signs and repilation of affected areas were observed. New mycological cultures of both areas were carried out, which were negative for Microsporum canis.Discussion: Although Microsporum canis is described as causing dermatophytosis in several animal species, it has apparently not yet been reported in maned wolves. Microsporum canis is one of the most isolated zoophilic dermatophytes in domestic cats and is also cited in reports of symptomatic wild felids, such as tigers, in which it has been identified as either the only agent of infection or in association with Trichophyton mentagrophytes. The occurrence is also high in domestic dogs. In the wild canids, Microsporum gypseum has been described in the gray wolf, Trichophyton mentagrophytes in wild foxes, and Microsporum canis in red fox, among others. The finding of zoophilic and geophilic dermatophyte fungi in healthy, free-living and captive wild animals confirms their role as carriers, probable reservoirs and disseminators of these organisms in the environment, and the potential risk they represent as causes of zoonoses. Zoophilic dermatophytes are usually transmitted by contact between individuals and contaminated fomites. In the case of M. canis in the red fox the contact was an asymptomatic domestic cat. In the present case the transmission was not determined, since the animal was rescued from the wild. Regarding the age group, young animals are more susceptible to dermatophytes than adults, probably related to the greater immunity of adults due to previous contacts or even the immaturity of the immune system of the young. The dermatophytosis diagnosis is generally based on anamnesis, physical examination of the lesion, Wood’s lamp examination, microscopic skin scraping, fungal culture, or even histology and PCR tests. In the present case, the final diagnosis was based upon by fungal culture in Sabouraud agar, which allowed to identify the dermatophyte species and,thus, the possible source of infection. Dermatophyte infections can be treated with systemic or topical antifungal medications. Because it was a young animal, it was chosen in the present case only for topical use, which proved to be adequate, probably due to the action of the drug in the areas of alopecia skin and the improvement of the systemic condition of theanimal. Knowing that the maned wolf is considered as a vulnerable species, it is important to know the diseases that affect this species, in order to carry out, when necessary, disease monitoring programs, preventive and therapies, which is essential for its preservation.Keywords: wild animal, disease, skin, dermatophyte.
