Abstract

New molecular diagnostic tools have recently allowed the discovery of human rhinovirus species C (HRV-C) that may be overrepresented in children with lower respiratory tract complications. Unlike HRV-A and HRV-B, HRV-C cannot be propagated in conventional immortalized cell lines and their biological properties have been difficult to study. Recent studies have described the successful amplification of HRV-C15, HRV-C11, and HRV-C41 in sinus mucosal organ cultures and in fully differentiated human airway epithelial cells. Consistent with these studies, we report that a panel of clinical HRV-C specimens including HRV-C2, HRV-C7, HRV-C12, HRV-C15, and HRV-C29 types were all capable of mediating productive infection in reconstituted 3D human primary upper airway epithelial tissues and that the virions enter and exit preferentially through the apical surface. Similar to HRV-A and HRV-B, our data support the acid sensitivity of HRV-C. We observed also that the optimum temperature requirement during HRV-C growth may be type-dependent.
