Deviance analysis resulting from the generalized linear
model approach showed no significant differences
between years, between seasons, nor between seasons
within each year in terms of AST presence. However, there
were significant differences between seasons when the
presence of both EV and RV were considered. The presence
of these pathogens was significantly more frequent
during the cold-dry season (0.75 and 0.35, respectively)
than in the warm-rainy season (0.10 and 0.05, respectively)
(Figure 1).
