The individual-level apparent seroprevalence of animal brucellosis from 2019 to 2021. A The trends of apparent seroprevalence in four counties from 2019 to 2021; the Y-axis represents the average individual-level positive rate of the county with seroprevalence % ± SE (p), and the X-axis represents years. B Differential analysis of apparent seroprevalence in different counties; C Differential analysis of apparent seroprevalence in different species; D Differential analysis of apparent seroprevalence in small and large ruminants; E Differential analysis of apparent seroprevalence in different flock sizes; F Differential analysis of apparent seroprevalence in different sexes. ns: no significant difference at P > 0.05. *Significant difference at P < 0.05. ** Extremely significant difference at 0.01 < P < 0.05
