M. hyopneumoniae has also been shown to bind and colocalize with fibronectin at the site of infection (Burnett et al., 2006; Jenkins et al., 2006; Wilton et al., 2009; Deutscher et al., 2010; Seymour et al., 2010, 2011, 2012; Bogema et al., 2011, 2012; Raymond et al., 2013, 2015; Tacchi et al., 2014, 2016; Jarocki et al., 2015) however, little is known about receptors that may be conducive to facilitating chronic infection such as those that are expressed on the surface of denuded epithelium. The gene discussed is FN1; the disease is infection.
