RESUMO

Pythiosis is caused by an aquatic fungus-like organism (Pythium insidiosum). It is considered an important public health issue as it can affect both animals and humans. This paper reports a case of gastrointestinal pythiosis in a dog. The patient was hospitalized for four days, during which the animal received supportive and symptomatic treatment. But the applied treatment was unsuccessful and the dog's clinical condition worsened, culminating in death. Complementary imaging tests such as radiography and ultrasonography, as well as hematological tests, were performed during the hospitalization period. The definitive diagnosis was reached in the postmortem as macroscopic and microscopic characteristics suggested the presence of intestinal granuloma and accentuated multifocal suppurative necrotic enteritis. Additionally, the histological evaluation revealed morphological structures compatible with P. insidiosum. Also, the results of nested PCR performed showed partial amplification (105 bp) of the ITS1 region of the ribosomal gene of P. insidiosum.(AU)

A pitiose é causada por um organismo aquático semelhante a um fungo (Pythium insidiosum) e considerada um importante problema de saúde pública, pois pode afetar animais e humanos. Este artigo relata um caso de pitiose gastrointestinal em um cão. O paciente ficou internado por quatro dias, período em que o animal recebeu tratamento de suporte e sintomático. No entanto, o tratamento aplicado não teve sucesso e o quadro clínico do cão piorou, culminando com a morte. Exames de imagem complementares, como radiografia e ultrassonografia, bem como exames hematológicos, foram realizados durante o período de internação. O diagnóstico definitivo foi feito na autópsia, pois as características macroscópicas e microscópicas sugeriam a presença de granuloma intestinal e acentuada enterite necrótica multifocal supurativa. Além disso, a avaliação histológica revelou estruturas morfológicas compatíveis com P. insidiosum. Além disso, a nested PCR foi realizada e mostrou amplificação parcial (105 pb) da região ITS1 do gene ribossomal de P. insidiosum.(AU)

RESUMO

Nocardia asiatica causing pyogranulomatous pleuropneumonia is reported for the first time in a dog coinfected with canine morbillivirus (CM), diagnosed based on epidemiological, clinical, haematological, images, microbiological, histopathological, polymerase chain reaction and hsp65 gene sequencing findings. The immunosuppression of CM probably favoured the opportunistic behaviour of N. asiatica. Despite the therapeutic measures, the animal died, mainly due to respiratory distress. The association of methods to improve early diagnosis, therapy procedures and prognosis of canine nocardiosis is discussed, as well as the close relationship between pets and their owners, which may favour the transmission of pathogens such as Nocardia from pets-to-humans, which poses an emerging public health issue.

RESUMO

Background: Adrenal incidentalomas are masses accidentally discovered during imaging examinations performed whenthere is no suspicion of adrenal disease. Even with a low prevalence, it is important to perform a reliable evaluation observing biological behavior and determining whether the hormonal activity is stimulated. Frequently, these masses are notfunctional, but in some cases, there is increased cortisol activity, and patients with adrenal incidentalomas may presenthyperadrenocorticism. This report aims to describe the clinical, tomographic, and histopathological aspects of a case ofadrenal incidentaloma detected in a routine abdominal ultrasound.Case: An 8-year-old, male, maltese dog with occasional emesis, halitosis, claudication of the left pelvic limb, and previous compensated and untreated cardiomyopathy was treated at the Veterinary Hospital of the Federal University of MatoGrosso (HOVET-UFMT). Physical examination revealed arterial hypertension and claudication, with the positive posteriordrawer test suggesting rupture of the cruciate ligament. The blood count showed no alteration, and the serum biochemistryrevealed a slight increase in the activity of alanine aminotransferase. In order to investigate this increase, an abdominalultrasound was performed. Slight hepatomegaly and a heterogeneous mass of irregular edges were observed with a moderate and difficult-to-delimit vascularization of the adrenal gland. Left knee radiography raised the suspicion of rupture ofthe cranial cruciate ligament due to the cranial displacement of the tibia in relation to the femur. Computed tomographywas performed to define the extent and delimitation of the mass, which was compatible with a tumor of the right adrenalgland characterized by the visualization of an abdominal mass...(AU)

RESUMO

La demodiciosis es una enfermedad causada por la proliferación excesiva de ácaros Demodex canis.La enfermedad puede clasificarse como adulto o juvenil localizada o generalizada, siendo identificada como una de las enfermedades de la piel más comunes en la clínica médica de rutina de los animales pequeños. El objetivo de este trabajo presentar dos casos de animales con demodiciosis generalizada, un juvenil y el otro adulto.(AU)

The demodicosis is a disease caused by the excessive proliferation of the mite Demodex canis. The disease can be classified as adult or juvenile and localized or generalized, being identified as one of the most common skin diseases in the routine of medical clinic for small animals.
