Erratum: Assessing parallel testing to improve detection of bovine tuberculosis at a slaughterhouse in Lahore, Pakistan

Abstract

The article ‘Assessing parallel testing to improve detection of bovine tuberculosis at a slaughterhouse in Lahore, Pakistan’ (SAJAS volume 54, issue 4, DOI: http://dx.doi.org/10.4314/sajas.v54i4.02) was initially published with an error in the second paragraph of page 497.
The incorrect sentence:
‘The OD of bovine PPD (ODPPD-B) stimulated was subtracted from OD of avian PPD (ODPPD-A) stimulated (ODPPD-B - ODPPD-A) and the calculated value ≥ 0.1 was kept as cut off for a positive, whereas for a negative result, the subtracted value would be < 0.1.’
The corrected sentence:
‘The OD of avian PPD (ODPPD-A) stimulated plasma was subtracted from OD of bovine PPD (ODPPD-B) stimulated plasma (ODPPD-B - ODPPD-A) and the calculated value ≥0.1 was kept as cut off for a positive, whereas for a negative result, the subtracted value would be < 0.1.’

This correction is important for the clarity and accuracy of the methodology described in the
manuscript.
