Samples negative for bovine papillomavirus (BPV)-1/2/4 and therefore with genotype unknown A – sample from Emiliano Zapata, Tabasco; B – sample from Libertad, Chiapas. Samples had cauliflower morphology suggesting that they be considered BPV positive

Bovine papillomavirus (BPV)-1 phylogenetic tree of Mexican isolates (partial L1 sequence). Sequences were compared with sequences from different nationalities recorded in the NCBI database, of which the accession numbers are indicated. The comparison used a neighbour-joining method in MEGA 10.1. RS – representative sample

Geographical bovine papillomavirus (BPV) genotype localisation in Mexico. Tabasco, Chiapas, and Veracruz states are considered breeder states and cattle collection centres for Central America. Nuevo León is a final feedlot destination state for national consumption or international exportation. The intensity of grey indicates the percentage of co-infection A – Chiapas; B – Tabasco; C – Veracruz; D – Nuevo León

Sera reactivity against WWL/synthetic peptide and antibody specificity against BPV A – Anti-wart antibody reactivity against WWL at 1: 100 dilution on day 7 and 1:10,000 on days 14 and 35; B – Anti-peptide serum reactivity against synthetic peptide at a titre of 1:1,000,000 on days 7, 14 and 30. Cut-off points (horizontal solid line) were calculated at 0.087 and 0.053, respectively. **** – extremely significant difference (Tukey test P < 0.0001); *** – highly significant difference (Tukey test P < 0.0002) (n = 2); ** – significant difference (Tukey test P < 0.0021); * - significant difference (Tukey test P < 0.0332) (n = 2); C – Anti-wart serum reactivity against peptide at titres of 1 : 10,000–1 : 1,000,000 on day 14 and at a titre of 1 : 10,000 on day 35; D – Anti-peptide serum reactivity against WWL at a titre of 1 : 10,000 on days 7, 14 and 35, and at a titre of 1 : 1,000,000 on days 14 and 35.
