Associations between presence and integrity of O. ochengi adult worm sections in bovine nodules and degranulating eosinophil (DE) score at eight weeks post-treatment. (Bold type indicates statistical significance. The associations between degranulation and worm integrity were positive in all cases; i.e. DE scores were moderate and/or high where the sections exhibited normal structure. Sample sizes varied between analyses because only worm sections that could be scored unambiguously for each characteristic were included. Zone boundaries were measured in micrometres.)
