If pathogenic bacteria are identified in the culture, then it is likely that they are the source of the infection. An infection is typically caused by a single type of bacteria, but wounds may have two or more pathogens (aerobes and/or anaerobes) that are contributing to the infection. This may indicate a mixture of normal flora and pathogens from a contaminated sample or from a dirty wound.
