“…In cattle tuberculosis (Cassidy et al, 1999), and cattle spongiform encephalopathy (Caramelli et al, 2003;Wells et al, 2005), tonsils are strategic entry points for pathogens. Therefore, increasing researchers to enter the field of mucosal immunology were interested in the morphological characteristics of tonsils in various species, including the humans (Nave et al, 2001;Idris et al, 2013;Jovi c et al, 2015), ovine (Cocquyt et al, 2005;Casteleyn et al, 2007Casteleyn et al, , 2008Casteleyn et al, , 2010, camels (Zidan and Reinhard, 2009;Jia et al, 2017), cattles (Manesse et al, 1998;Velinova et al, 2001;Palmer et al, 2009Palmer et al, , 2011Zidan and Pabst, 2011), pigs (Belz and Heath, 1996;Williams and Rowland, 1972;Liu et al, 2012), horses (Kumar and Timoney, 2005), dogs Heath, 1995a, 1995b), and rabbits (Harrison et al, 1970;Oláh and Everett, 1975). Unfortunately, as a special plateau animal, there are no detailed anatomical or histological dates of yak tonsils.…”
