Salmonella enteritidis colonization in turkey poults. 1997

State Veterinary Laboratory Stuttgart, Germany.

An experimental trial on the colonization of two Salmonella enteritidis strains (phage types 4 and 8) originating from meat turkey flocks, were carried out. Three-day old poults were inoculated orally with approximately 10(6) cfu/bird (one group with PT8 and the other with PT4). clinical signs were not observed in any of the groups. The total reisolation rates from cloacal swabs in birds inoculated with PT4 was higher than from birds inoculated with PT8. The inoculated strains could also be detected in contact birds. Examination of internal organs 21 days p.i. revealed higher isolation rates in the group infected with PT4 than with PT8. The results indicate that both phage types of S. enteritidis were able to colonize the intestinal tract and the internal organs of turkey poults. However, the colonization and duration of shedding differed between the two phage types. This may be due to the fact that PT8 strain used was free from the S. e. virulence plasmid 37 MDa.

D002988	Cloaca	A dilated cavity extended caudally from the hindgut. In adult birds, reptiles, amphibians, and many fishes but few mammals, cloaca is a common chamber into which the digestive, urinary and reproductive tracts discharge their contents. In most mammals, cloaca gives rise to LARGE INTESTINE; URINARY BLADDER; and GENITALIA.	Cloacas
