The Response of Normal and Iron Anemic Calves to Nasal Infection with an Attenuated Strain of Parainfluenza-3 Virus

Abstract

Calves with experimentally induced iron deficiency anemia and normal calves, both groups deprived of colostrum, were exposed to intranasal instillation of an attenuated parainfluenza-3 virus strain. The calves became infected, but there was no difference in the clinical picture between the 2 groups of calves. Neither was there a difference in the humoral or local immune response to parainfluenza-3 virus.
