SALIVATION
Following challenge, the most common clinical signs were lethargy and respiratory abnormalities. The lone survivor from the IGIV treatment group presented with rapid respiration during the first observation on Day 4 and with reduced food consumption on Days 8 and 9.

Most of the surviving rabbits in the ANTHRASIL-treated group presented with respiratory abnormalities, which were resolved by Day 12. Three animals (one IGIV-treated and two ANTHRASIL-treated) were observed to have labored breathing, sneezing and salivation. These clinical signs were most probably the result of the
