“…Numerous studies have been reported on developing ELISA methods for the detection of FQs, including CPFX (Mellgren and Sternesjö, 1998), enrofloxacin (Mellgren and Sternesjö, 1998;Watanabe et al, 2002), norfloxacin (Watanabe et al, 2002;Huet et al, 2006), pefloxacin (Mellgren and Sternesjö, 1998;Huet et al, 2006), and sarafloxacin (Lu et al, 2006). Moreover, Bucknall et al (2003) reported results concerning a polyclonal antibody against CPFX with a limit of detection (LOD) of 4 ng/ml (Bucknall et al, 2003).…”
