Il virus della leucemia bovina viene trasmesso a livello di mandria per via orizzontale attraverso sangue infetto. Un studio giapponese di campo sviluppato durante l’arco di tre anni (2013-2016) ha voluto confermare quale potenziale fattore di rischio di trasmissione del virus della leucemia bovina la presenza stabile di mosche succhiasangue e determinare l’efficacia del controllo dei vettori della patologia nella prevenzione della trasmissione del VLB.
