Bacteriological Examination of Shells and Contents of Eggs Laid by Turkeys Naturally or Artificially Infected with Salmonella typhimurium

Abstract

EVIDENCE suggesting transmission of Salmonella typhimurium to turkey poults by means of infected eggs has been presented by Cherrington, Gildow, and Moore (1937) who recovered the organisms from ovaries of reacting turkeys and from “dead in shell” embryos. Lee, Holm and Murray (1936) reported the isolation of S. typhimurium from ovaries of artificially infected turkey hens. Hinshaw (1943) reported the recovery of the organisms from the ovary and oviduct of turkey hens. Pomeroy and Fenstermacher (1941) reported the isolation of parathyphoid organisms from 7 of 200 eggs that were incubated and failed to hatch, and they reported that S. typhimurium was isolated from the ovaries of 2 out of 9 reactors laying these eggs. These same workers (1941) showed that S. typhimurium passed through the unbroken shell and infected the embryos. Schalm (1937) showed that this same mode of infection can occur in chicken eggs.In the studies here presented .
