Objective/background: The present study was aimed at detecting Mycobacterium bovis in artisanal cheese using real-time quantitative polymerase chain reaction.
Methods: One hundred seven cheese samples (250g) were purchased in 107 commercial establishments including neighborhood grocery stores, bakeries, and open-air markets from 19 municipalities of the state of Pernambuco, Brazil. Ten grams of each cheese sample were macerated with sterile saline solution in a sterile bag and DNA was extracted from 20mg of the macerated material using the Wizard SV Genomic DNA Purification System.
