Survival of Salmonella enterica in freshwater and sediments and transmission by the aquatic midge Chironomus tentans (Chironomidae:Diptera)

Article Abstract:

The auhtors have investigated nalidixic acid-resistant strain of Salmonella enterica serovar Typhimurium mr-DT-104. The survival of this strain in water, sediments and chironomid larvae has been tested in order to identify the possibility of chironomids as hosts for the movement of mr-DT-104, and the results are reported.
