ABSTRACT
Resumen El virus de la leucemia felina (ViLeF) es una de las principales enfermedades retrovirales de la familia Felidae que causan la muerte de sus individuos; de ahí interés diagnóstico y preventivo para la salud animal. El propósito de este artículo es determinar la prevalencia de infección por el ViLeF por serodiagnóstico del antígeno p27, en cuatro municipios del sur del valle de Aburrá, Colombia, usando los registros de los centros de diagnóstico del área. Se realizó un estudio descriptivo, transversal y retrospectivo, entre los años 2013-2015, que incluyó la revisión de 1718 pruebas diagnósticas de felinos domésticos del área urbana de Medellín, Envigado, Sabaneta y Caldas, procedentes de los centros de diagnóstico clínico del valle de Aburrá. El diagnóstico de ViLeF se realizó en muestras de suero por el inmunoensayo comercial Elisa (Idexx Laboratories©, Snap Combo Plus®, Maine, EUA). Los datos se procesaron en Statgraphics Centurión XVy se realizaron las pruebas estadísticas de Ji2 y Tukey. Del total de muestras, 376 (21,89 %) fueron positivas a la presencia del antígeno p27 de ViLeF. La edad de infectados osciló entre los 2 a 36 meses, hubo una mayor prevalencia en raza doméstica de pelo corto (DPC) y en machos. El porcentaje la prevalencia de ViLeF en el estudio fue de 21,88 %, siendo de importancia epidemiológica en el sur del Valle de Aburrá, Antioquia, Colombia.
Abstract Feline Leukemia Virus (FeLV) is one of the main retrovirus diseases of the Felidae family causing the death to the subjects. Therefore, there is a diagnostic and preventive interest regarding the animal health. This article aims to determine the infection prevalence due to FeLV after a p27 antigen serodiagnostic test applied in four towns in the southern Valle del Aburrá, Colombia, using the records of the diagnostic centers in each area. A descriptive, cross-sectional and retrospective study was conducted for the period 2013-2015, in which 1718 diagnostic tests from home felines were reviewed. These cases were from the urban area of Medellín, Envigado, Sabaneta and Caldas making part in the clinical diagnostic centers of the Valle de Aburrá. The FeLV diagnosis was conducted in serum samples with commercial immunoessay ELISA (IDEXX Laboratories©, Snap Combo Plus®, Maine, EUA). Data were processed in Statgraphics Centurión XV and statistical tests Ji2 and Tukey were conducted. Out of the total samples, 376 (21.89 %) were positive to p27 antigen for FeLV. The infected animals were from 2 to 36 months old. There was a higher prevalence among home races with short hair (SHR) and males. The FeLV prevalence percentage in the study was 21.88%, a figure with epidemiological significance in the southern Valle de Aburrá, Antioquia Province, Colombia.
ABSTRACT
A cross-sectional study was carried out on cats attending the Small Animal Hospital at the Faculty of Veterinary Sciences of the University of Buenos Aires to assess the prevalence and associated risk factors of Feline immunodeficiency virus (FIV) and Feline leukemia virus (FeLV) in the city of Buenos Aires, Argentina. Blood samples from 255 cats with symptoms compatible with FIV or FeLV infection, collected between 2009 and 2013 were analyzed by serology (immunochromatography, IA) and by hemi-nested PCR (n-PCR). The IA and n-PCR assays showed similar percentages of positivity for FIV while the n-PCR test was more sensitive for FeLV. Differences between the diagnostic tests and their choice according to the age of the animal are discussed. The clinical histories of ninety of the 255 cats showed blood profiles similar to others previously reported and revealed a higher risk of infection in male adult cats with outdoor access.
Para determinar la prevalencia en la ciudad de Buenos Aires del virus de la inmunodeficiencia felina (FIV) y del virus de la leucemia felina (FeLV), y analizar los factores de riesgo que pudieran estar asociados a ellos, se realizó un estudio transversal en gatos atendidos en el Hospital de Pequeños Animales de la Facultad de Ciencias Veterinarias de la Universidad de Buenos Aires. Se analizaron por serología (inmunocromatografía --#91;IA--#93;) y por hemi-nested PCR (n-PCR) 255 muestras de sangre de gatos con síntomas compatibles con infección por FIV o FeLV. La IA y la n-PCR revelaron porcentajes similares de animales positivos para FIV, mientras que para FeLV el diagnóstico por n-PCR resultó más sensible. Se discuten las diferencias halladas entre los métodos diagnósticos y su elección según la edad del animal. Las historias clínicas de 90 de los 255 gatos mostraron perfiles sanguíneos similares a otros ya reportados y revelaron el mayor riesgo de infección con ambos virus en machos adultos con acceso al exterior.
