a
The results are for individual flies recovered from rooms housing hens challenged with Salmonella serovar Enteritidis on day 3 postchallenge.
b
The salivary gland, crop, and then the gut were aseptically dissected out from exteriorly disinfected individual flies and cultured. The results represent the presence (+) or absence (−) of Salmonella serovar Enteritidis cells in each tissue from each fly.
c
P < 0.001 versus results for the crop and salivary gland.
