In Brazil there are few studies on the occurrence of the feline immunodeficiency virus (FIV) infection and its subtypes, which are essential for the development of vaccines and new diagnostic tests. The present study investigated the occurrence of the FIV infection between 2010 and 2011 in domestic cats submitted to medical attendance in the city of Pelotas and nearby area. Total blood samples of seventy cats, suspected (28) or not (42) of infection by FIV were analyzed by nested PCR in order to perform a diagnosis. The results pointed to a FIV infection frequency of 15.7% (11/70) and the analysis of the risk factors related to infection (sex, age and clinical condition) evidenced a greater occurrence in cats up to 10 years of age with chronic and recurrent infections. Eight samples found positive by nested PCR were submitted to DNA sequencing indicating that only the subtype B was detected in the studied region.

The feline leukemia virus (FeLV) was described in 1964 by William Jarrett and collaborators wen find viral particles attached to the membrane of lymphoblasts in cat with lymphoma. The virus belongs to the family Retroviridae, subfamily oncornavirus. With worldwide distribution, the occurrence of FeLV has 1.6% in healthy cats and 10.8% in sick cats in Brazil. The mortality of persistently viremic animals in catteries is about 50% in two years and 80% in three years. In catteries that have endemic feline Coronavirus (FCoV), FeLV and / or Feline Immunodeficiency Virus (FIV), the FeLV infection has greater contribution to mortality. The test for infection and FeLV positive cats segregation is the main way to prevent the spread of infection. The diagnostic methods are based on clinical signs and changes compatible with FeLV infection observed by physical examination, complete blood count, X-ray, bone marrow aspirate and biochemical. The viral p27 protein is produced in infected cells in high amounts and is found in abundance in the cytoplasm and in body fluids enabling diagnosed methods such as enzyme-linked immunosorbent assay - ELISA and direct immunofluorescence, detection of viral genome (Chain Reaction Polymerase - PCR) and detection of the virus by virus isolation. Although diagnostic tests are highly sensitive, it should be made more than a confirmatory test, especially serological due to variable characteristic of the progress of infection

In Brazil, the importance of leishmaniosis it is seen in its high incidence and huge distribution, as well as the possibility of became a lethal disease. It´s a zoonosis of canids, felines, rodents e marsupials, that is transmitted to men through vector bugs. Visceral leishmaniosis, the most serious and prevalent form, strongly became as an emergent and endemic disease, seeing in many Brazilian states, also bringing a lot of problems to public health. Because of this, it´s notable that the increase of urbanization in the last 20 years put in quest all the control strategies existent, the measures implanted until today were incapable to eliminate the transmission as to impede the occurrence of new epidemics. The prevention of dogs through imunoprophylaxis appear as an alternative, however to have a safe use it´s needed other studies, that can bring real results. The research below shows the increase of visceral leishmaniosis during the years, associated mainly to human cases, besides of dismember the tries used or that will be used with objective of dicrease the spread of leishmaniosis

Cholangiohepatitis is a common hepatic disorder in cats that is second only to hepatic lipidosis in frequency. The cholangitis-cholangiohepatitis complex is known as the diseases that involve the biliar tract inflammation and may extend to the liver. The classification of the cholangiohepatitis is still controversial, in this present study the following classification was used: Acute Cholangiohepatitis, Chronic Cholangiohepatitis, Lymphocitic Cholangitis. The cholangiohepatitis may be associated with pancreatitis and inflammatory bowel disease, this association is known as feline triaditis. The diagnosis is based on the clinical signs, alterations in laboratory exams and ultrasonography alterations, but the definitive diagnosis is only possible through liver biopsy. The treatment for each type of cholangiohepatitis differs, hence the importance of the right diagnosis. This study aimed to do a review over the ethiology, clinical presentation, diagnosis and treatment for this disease

Este trabalho teve como objetivo a realização de um levantamento bibliográfico da situação em que a cidade de Rio Claro, interior de São Paulo, se encontra em relação à Leishmaniose Tegumentar Americana, uma vez que, o município foi apontado como foco da doença no ano de 2000 por mídias regionais. O trabalho visa identificar o período de maior número de casos bem como a situação atual da doença na cidade. Este levantamento bibliográfico, contou com auxilio de agentes de saúde da Secretaria Municipal de Saúde e Instituto Adolfo Lutz presente na cidade, além de departamentos da prefeitura municipal envolvidos com tema. Ficou evidente que o município enfrentou períodos de surtos da doença, porém, atualmente a LTA está controlada, apresentando poucos casos em relação há anos anteriores. O atendimento aos doentes é oferecido gratuitamente na rede municipal de saúde. A cidade procura através dos órgãos envolvidos com o tema, conscientizar a população quanto ao risco e método de prevenção

Hypertrophic cardiomyopathy (HCM) is the most common heart disease in the feline specie, more frequently affecting pure-breed males such as Ragdolls and Maine Coons. HCM can be primary (idiopathic) or secondary, when other diseases such as hyperthyroidism are involved. The disease is characterized by an increase in the diameter and thickness of the left ventricular wall, with consequent diastolic dysfunction. Mitral regurgitation happens due to compromised ventricular filling, leading to an increased left atrium size and consequent cardiogenic pulmonary edema. Along with the progress of modern veterinary medicine, many diseases could be addressed more successfully on small animal internal medicine, such as feline HCM. This article brings a literature review of the feline hypertrophic cardiomyopathy, focusing on its etiology, physiopathology, clinical presentations, diagnostic methods, therapeutics and prognosis

A leishmaniose tegumentar é causada pela picada da fêmea dos insetos flebotomíneos. As lesões podem evoluir de pápulas para úlceras, que apresentam fundo granuloso e bordas infiltradas, as quais são indolores, podendo ser únicas ou múltiplas. Trata-se de uma doença negligenciada e o investimento em seu tratamento é desprezível. Até hoje, são empregados no tratamento medicamentos a base de antimonial pentavalente, além de outros fármacos como pentamidina, anfotericina B, paromomicina, imidazoquinolina, antifúngicos, como o fluconazol (FLU). As microemulsões (MEs) melhorarem a solubilidade e estabilidade dos fármacos, além de proporcionarem ação prolongada, vetorização diferenciada para determinados tecidos ou órgãos do organismo. Este trabalho teve como objetivos desenvolver e caracterizar MEs contendo FLU, caracterizar estruturalmente por meio de análises de microscopia de luz polarizada, análise do tamanho das gotículas, análise do perfil de textura e avaliação da bioadesão. Para o estudo de estabilidade foram empregados ensaios de avaliação visual e determinação do pH. Quanto aos ensaios biológicos in vitro, foram realizados ensaios colorimétricos das amostras visando verificar se o sistema desenvolvido permite a potencialização do poder leishmanicida do FLU contra as formas promastigotas da Leishmania amazonensis. Pelo diagrama de fases observou fases líquido-cristalinas confirmadas pela microscopia de luz polarizada, e foram selecionadas três formulações: uma SLT e duas SVT. Todos os ensaios de caracterização estrutural para a F2 sofreu variação quando acrescentou o fármaco, exceto para o potencial zeta, difração de raios X e bioadesão. Não houve alteração no ensaio estabilidade físico-química no período analisado. Os ensaios biológicos in vitro evidenciaram, nas condições metodológicas, inefetividade do sistema contra as formas promastigotas de L. amazonensis
