In the original version of this article, in the “Materials and methods” section, under the subsection “Animal experimentation and preparation of sera from NCTD-treated rabbits”, the third sentence currently reads:

‘NCTD was given via the intravenous injection to the rabbits once daily at a dose of 10 mg mL−1 100 g−1 body weight for 3 days’

Should read:

‘NCTD was given via the intravenous injection to the rabbits once daily at a dose of 1 mg 0.2 mL−1 kg −1 body weight for 3 days’.
