Resumen
RESUMEN: El virus de la leucemia felina (FeLV) es un gammaretrovirus que afecta a felinos domésticos de todo el mundo y esporádicamente a felinos salvajes. La forma más común de contagio es la transmisión horizontal, siendo más frecuentes las infecciones por contacto con saliva y por consumo de leche de una gata infectada. Recientemente se han logrado grandes avances en la comprensión y la clasificación de los gatos infectados por el FeLV, reconociéndose en la actualidad cuatro diferentes tipos de infección. Clínicamente, la enfermedad se caracteriza por el desarrollo de enfermedades neoplásicas, no neoplásicas y enfermedades reproductivas; su diagnóstico definitivo se puede realizar por medio de pruebas como ELISA, inmunocromatografía y PCR. El tratamiento en los animales clínicamente enfermos se basa principalmente en el manejo sintomático, aunque se han logrado progresos en el uso de medicamentos antivirales. Dada su fácil transmisión, es de suma importancia la prevención del contagio en gatos sanos a través del aislamiento de animales enfermos y la vacunación. En Colombia se han realizado algunos estudios exploratorios que han demostrado prevalencias superiores al 20% en gatos domésticos; sin embargo, a la fecha no se han realizado estudios moleculares que permitan la caracterización del FeLV circulante en el país ni se ha logrado la implementación de medidas más enfocadas de prevención y control.
