The work was conducted to determine the incidence of microbial contaminants in two clones of taro (‘INIVIT MX-2007’ and ‘INIVIT MC-2012’) on the establishment and multiplication stages. The contaminated culture vials were counted and the percentage of microbial contamination was determined by clone in each subculture. Different contaminants were isolated and characterized morphologically and culturally. A high incidence of microbial contaminants in the two taro clones were found. Bacteria caused the greatest damage in the establishment and multiplication stages. Key words: bacteria, in vitro plants, taro
