InfecŃiile produse de virusuri din fam. Papillomaviridae 127 zile, după care crusta se elimină, lăsând o zonă denudată care se vindecă în 30-35 zile. FormaŃiunile apar ca proliferări neregulate, papiliforme, nedureroase, interesând uneori şi straturile mai profunde. Ele au dimensiuni variabile, de până la câŃiva milimetri diametru (14). Histopatologic, se constată prezenŃa, în celulele epidermice, a unor incluzii polimorfe intracitoplasmatice, de mărimi apreciabile. Ele se evidenŃiază numai până la 14 zile de la debutul bolii. În Ńesuturile subcutanate apar numeroase fibroblaste, histiocite, polimorfonucleare şi rare plasmocite. La periferia papilomului se constată o vascularizaŃie intensă (14). La elefant. S-au descris leziuni papilomatoase cutanate la elefanŃii captivi (African elephantus). Leziunile au aspectul unor formaŃiuni nodulare, care pot să progreseze în largi fibroame nodulare sau să regreseze. Histologic, în stadiile timpurii de dezvoltare a tumorilor papilomatoase, s-a evidenŃiat hiperplazia şi hipertrofia celulelor epiteliale, acestea conŃinând incluzii intranucleare amfoterice. În leziunile mai vechi s-au observat fibroblaşti, colagen, infiltrat inflamator celular mixt, fără a se mai evidenŃia incluzii. La examenul electronomicroscopic s-au evidenŃiat particule virale, cu dimensiuni de 95-103 nm. La testul peroxidază-antiperoxidază nu s-au detectat antigene specifice papilomavirusurilor (6). Polipi au fost evidenŃiaŃi şi în tractusul urogenital (10). La broaştele Ńestoase. Îmbolnăviri au fost semnalate la Ńestoasele boliviene, fără a se cunoaşte calea de transmitere. Papiloamele sunt frecvente la nivelul capului, iar la nivelul plastronului se manifestă prin leziuni ulcerative. Histopatologic, pe biopreparate din piele se constată hiperacantoză, iar prin microscopia electronică s-au evidenŃiat particule virale în structuri paracristaline, cu diametru de 42 nm (9). La şopârle. Au fost descrise papiloame la guşter (Lacerta viridis), transmiterea făcându-se prin muşcături în regiunea capului şi a cozii, în contextul comportamentului prenupŃial. Foarte rar se constată apariŃia de papiloame în alte regiuni corporale. Aspectul tumorilor este dens, au culoare cenuşie închisă spre negru, au dimensiuni variabile, de la 2 la 20 mm diametru. Histopatologic se observă hipertrofia nucleului cu hipercromatoză periferică şi incluzii intranucleare în celule epidermice (9). La alte specii. Papiloame au mai fost descrise la elani (virusul papilomatozei elanilor), hamsteri (virusul papilomatozei hamsterilor), şobolani (virusul papilomatozei multimamate), foci (virusul papilomatozei focilor), cimpanzei (virusul 1 al cimpanzeilor), şi la maimuŃele Rhesus (virusul papilomatozei Rhesus).
