The Relationship of the Chicken Egg to Selected Paratyphoids

Abstract

SPECIES of Salmonella occur in poultry flesh (Galton et al., 1955) and are the causative agents of the paratyphoid disease4 in chickens (Darby and Stafseth, 1942; Edwards and Bruner, 1943; Edwards et al., 1948; Hinshaw et al., 1944; Jungherr and Clancy, 1939; and Schalm, 1937). They also occur in egg products (Solowey et al., 1947Solowey et al., 1948; cf. Byrne et al., 1955). The relationship between the carrier hen and the transmission of the organism to the egg product has, however, been studied only to a limited extent. Following an outbreak of disease among sailors, Watt (1945) recovered S. Montevideo from 11 of 14 shell eggs from a stock of eggs remaining aboard ship. He also recovered S. derby and S. choleraesuis during the culture of shell eggs from Iowa farms. Felsenfeld et al. (1950) recovered S. typhimurium once, and S. bareilley twice during the culture of 500 market eggs. Recoveries of . . .
