Dirofilaria immitis é um nematoide de ampla distribuição geográfica, que ocorre com maior frequência em áreas quentes e úmidas do planeta. O primeiro registro sua ocorrência na América Sul foi realizado 1878, no Brasil. Naquela época os registros eram poucos raramente fácil obtenção, razão pela qual reuni-los facilitará a recuperação da memória ao longo dos anos. Quatro bases dados (Scopus, MEDLINE, LILACS PubMed) foram estudadas utilizando-se as palavras-chave “Dirofilaria” ou “heartworm”,...

Transmissible venereal tumor (TVT) is a malignant round cell neoplasm that primarily affects the genital region of dogs. Despite being sexually transmitted, transmission can occur through contact with mucous membranes and cutaneous tissue. Although less routine, TVT has been described in several extragenital regions, such as nasal plane, oral cavity, eyeball, eyelid, anus. metastases are infrequent, they skin, inguinal lymph nodes, liver, kidneys, spleen, intestine, heart, brain, lungs,...

Dirofilaria immitis is a nematode that infects canids worldwide as well other mammalian species, including humans. Worms and dogs are adapted to one another, making the best urban host for parasite. Nevertheless, 30% of do not sufficiently present microfilaremia, is, low larval load impairs transmission by mosquitoes diagnosis its detection in blood samples. Therefore, canine must always include microfilaria test serological tests detect adult worm antigens. To describe clinical findings...

Dirofilaria immitis is a mosquito-borne nematode that often infects dogs worldwide and causes what commonly referred to as heartworm disease. The infection recognized being more prevalent in tropical subtropical coastal regions; however, due recent climate changes, it has been detected regions previously considered free of infection. asymptomatic animals presented this case report had their infections opportunistically. One was for routine checkup the other pre-operative evaluation. In case,...

Heartworm disease is caused by a mosquito-borne parasite that can affect many different mammalian species and has worldwide distribution. The agent, Dirofilaria immitis (Leidy 1856), infect mainly dogs but feline infection have been frequently reported in the last decade. Feline heartworm difficult to detect, therefore, low prevalence could reflect true or poor diagnostic efficiency. As mosquitoes are known be attracted differently species, were collected from both cattery contiguous home...

Dirofilariasis, a parasitic disease caused by the nematode Dirofilaria immitis, commonly known as heartworm, primarily inhabits pulmonary artery and right heart of dogs other animals. The is transmitted through diptera, predominantly from Culex, Aedes, Anopheles genera. Dirofilariasis cosmopolitan in nature, endemic coastal regions tropical climates. Factors such temperature, humidity, vector density, presence definitive hosts significantly contribute to spread this disease. In state Rio de...

Tricuspid valve dysplasia consists of morphological changes in the cusps, chordae tendineae and papillary muscles, which may present greater amplitude between these structures. It stands out as a common congenital heart disease felines rarely found dogs. In large pigs, few reports are literature about this agenesis, no pigs classified micropigs. A retrospective study carried by F.S. Hsu S.J. Du Taiwan, identified among 1,906 necropsied 83 animals that had some disease, with 42 (34%) affected...

Epistaxis is defined as bleeding from the nasal cavity and can be related to systemic causes leading coagulation disorders, most commonly hemoparasitosis, or localized changes in itself (e.g., intranasal neoplasms). Transmissible venereal tumors (TVT) are malignant round cell neoplasms characterized by an anomalous proliferation of tumor cells disseminated mainly direct contact between animals. Although transmitted sexually, transmission through with mucous membranes skin tissue also occur,...

Background: Brachycephalic dogs have several abnormalities in the airways, which generate clinical manifestations that impair quality of life these animals. Primary alterations promote airflow obstruction and increase intraluminal negative pressure, causing secondary due to a cycle inflammation with consequent obstruction. With onset other can be observed, such as snoring, reverse sneezing, coughing, dyspnea, cyanosis, syncope, vomiting. Endoscopic examination airways allows visualization...

 The aim of the present study was to differentiate hypertrophic cardiomyopathy (HCM) from concentric left ventricular hypertrophy (CLVH) and compare their echodopplercardiography measurements in random bred domestic cats. After owners consent cats any sex or age with no history heart disease were randomly submitted physical examination echocardiogram. When on echocardiogram, further examined by chest X-rays, ultrasonography laboratory work. Those presenting cardiac diagnosis that could...

Pulmonary atelectasis is a disease characterized by the collapse of pulmonary alveoli, leading to partial or total loss function in affected lung, and mostly described older dogs. It occurs due chronic inflammatory obstructive processes such as pneumonia. In infants who do not feed directly from mother, it common develop aspiration pneumonia inhalation milk replacer. Once aspirated, food generates an process airway that alters surfactant, increases mucus production, causes consequent...

To determine the M-mode echocardiography reference measurements for Brazilian random bred cats in Rio de Janeiro, Brazil, Cats presenting routine care were examined by echocardiography. Animals with free wall values ​​of left ventricle and/or interventricular septum above 5 mm not included. A total of 125 included study. The correlation body score condition (BSC) was positive systole (LVWs)  and ventricular diastole (LVWd) . LVWd BSCs 3 4 different , those also different. LVWs...
