a CL signal stability of the bioassay within dissimilar milk samples qualities (healthy, sub-clinical or clinical mastitis) and Hb-MNPs (control); b The corresponding CL values within different milk samples for two predominant pathogens (Strep. dysgalactiae and E. coli). Data are reported as mean ± SD (n ≥ 3). *Statistically different (t-test, p < 0.05)
