RATTUS NORVEGICUS RATS AS POSSIBLE CARRIERS OF ERYSIPELOTHRIX
Abstract
At the Leninakan meat canning plant, where it is possible for brown rats to have access to infected meat carcasses, erysipeloid infection of the mucous membrane of the pharyngeal ring in these rodents exceeded 30.7%, while infection of rats taken from other places did not reach 4%. Feeding brown rats material known to be contaminated with a culture of erysipelothrix var. suis did not cause their death and a clinically expressed disease was not even observed. However, 44% of all the infected animals remained erysipelothrix carriers for a certain period of time (10--25 days). Rats, under the conditions present in places dealing with food, may play a specific role in the spreading of erysipeloid infection by the mechanical route and as a result of being carriers. This again emphasizes the problem of the regular and organized eradication of rats.
