ABSTRACT

Using a retrospective study, 493 cats tested for FeLV and FIV were selected for analysis of the association between hematologic findings and positivity at immunoassay test. Individual and hematologic variables were assessed considering the influence of results using univariate and multivariate logistic regression analysis. Out 153 of the 493 cats were positive for FeLV (31%), 50 were positive for FIV (10.1%) and 22 were positive for both FIV and FeLV (4.4%). Multivariate analysis detected significant associations between FeLV infection and age below 1 year (p=0.01), age from 1 to 10 years (p=0.03), and crossbreed (p=0.04). Male cats were more likely to be FIV-positive (p=0.002). Regarding hematological changes, FeLV-positive cats have higher odds to anemia, leukopenia and lymphopenia than FeLV-negative cats. FIV-positive cats are more likely to have anemia than negative. Identification of associated factors related to animal status and correlation of hematological disorders with infection by retroviruses in cats could be useful for detecting these retroviral diseases in cats.(AU)


Através de um estudo retrospectivo, 493 gatos testados para FeLV e FIV foram selecionados para análise da associação entre as alterações hematológicas e a positividade no teste imunoenzimático. Variáveis individuais e hematológicas foram consideradas para verificar a influência dos resultados utilizando análise de regressão logística univariada e multivariada. Um total de 153 de 493 gatos avaliados foram positivos para o FeLV (31%), 50 foram positivos para o FIV (10,1%) e 22 foram positivos para FIV e FeLV (4,4%). Análise multivariada detectou uma associação significativa entre a infecção pelo FeLV e a idade abaixo de 1 ano (P=0,01), idade entre 1 a 10 anos (P=0,03) e raça mista (P=0,04). Gatos machos foram mais predispostos a serem positivos para FIV (P=0,002). Com base nas alterações hematológicas, gatos positivos para o FeLV tem maior odds para apresentar anemia, leucopenia e linfopenia que os negativos. Gatos positivos para FIV possuem maiores chances de apresentarem anemia que os gatos negativos. A identificação dos fatores associados à infecção relacionados ao perfil do animal e a correlação com os distúrbios hematológicos com a infecção, pode ser útil para detecção das doenças retrovirais em gatos.(AU)

ABSTRACT

This search aimed to investigate FIV and FeLV infections in domestic cats, analysing the epidemiological profile of the disease as well as additional infection with Leishmania sp. We evaluated 88 domestic cats for the presence of FIV, FeLV and Leishmania sp. infection. Eleven (12.5%) cats were positive for FIV infection, four (4.5%) were positive for FeLV, and two were co-infected. However, none was infected with Leishmania sp. The prevalence for FIV infection was higher than FeLV, and those observed in other regions, but no factor was associated with the infection by FIV and FeLV in this study.(AU)


Esta pesquisa teve o objetivo de investigar a infecção em gatos domésticos por FIV e FeLV, analisando o perfil epidemiológico destas doenças, assim como a infecção por Leishmania sp. Oitenta e oito gatos domésticos foram avaliados pesquisando a infecção por FIV, FeLV e Leishmania sp. Onze (12,5%) gatos foram positivos para infecção por FIV, quatro (4,5%) para FeLV, e dois gatos apresentaram co-infecção pelos dois vírus. Entretanto, nenhum gato doméstico apresentou infecção por Leishmania sp. A prevalência da infecção para FIV foi maior que a observada para FeLV, e que a observada em outras regiões, mas nenhum fator teve associação à infecção neste estudo.(AU)

ABSTRACT

A 1.6-year-old male domestic short hair cat was brought to the Veterinary Medical Teaching Hospital, Kasetsart University, with signs of severe anemia, depression, and general lymph node enlargement. Complete blood count revealed leukocytosis and massive undifferentiated blasts. Testing for antibodies specific to feline leukemia virus (FeLV) was positive, and FeLV nucleic acid was confirmed by nested polymerase chain reaction. Base on cytochemistry and ultrastructure, the cat was diagnosed with acute monoblastic leukemia.

ABSTRACT

Investigou-se a ocorrência da infecção pelo vírus da imunodeficiência felina (FIV) e pelo vírus da leucemia felina (FeLV) em gatos domésticos, provenientes de dois abrigos, no município de Belo Horizonte. Amostras de sangue de 145 animais foram coletadas e testadas para detecção do FIV pela reação em cadeia da polimerase (PCR). Destas amostras, 40 foram testadas para o antígeno p26 de FeLV por meio de ELISA. Observaram-se duas fêmeas (1,4 por cento) e quatro machos (2,8 por cento) positivos para FIV e nove fêmeas (22,5 por cento) e quatro machos (10,0 por cento) positivos para FeLV


The occurrence of the feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV) was investigated in domestic cats from two shelters of Belo Horizonte. Samples from 145 cats were collected and tested for FIV by the polymerase chain reaction (PCR). Forty out of 145 samples were tested for FeLV p27 antigen by a commercial ELISA kit. Two females (1.4 percent) and four males (2.8 percent) were positive for FIV. For FeLV tests, 13 cats (32.5 percent) were positive, being nine females (22.5 percent) and four males (10.0 percent)
