EmaA is an adhesin and involved in autoaggregation. (A) Mean adherence to human epithelial cells by A. aphrophilus with the wild-type emaA gene, an interrupted emaA gene, and the interrupted emaA gene reverted to the wild type. (B) Mean autoaggregation of A. aphrophilus with the wild-type emaA gene, an interrupted emaA gene, and the interrupted emaA gene reverted to the wild type. Each graph shows data from biological replicates performed in triplicate. Error bars represent standard errors. An asterisk denotes a P value of <0.05 obtained from a paired t test.
