The lactic acid-induced acid tolerance response in Salmonella enterica serovar Typhimurium induces sensitivity to hydrogen peroxide

Article Abstract:

The study conducted identified genes involved in lactic acid-induced acid tolerance response of Salmonella serovar Typhimurium and related transcriptional changes in bacterial phenotypes, including resistance to acidity and sensitivity to oxidative stress. Adaptation of Salmonella serovar Typhimurium with HCI or mixtures of short-chain fatty acids induced resistance to hydrogen peroxide and opposing hydrogen peroxide phenotypes were the result of type of acidulants used in experiments.

Survival and transmission of Salmonella enterica serovar typhimurium in an outdoor organic pig-farming environment

Article Abstract:

A study was conducted to assess the Salmonella infection dynamics in organic outdoor pigs and to determine the level of Salmonella contamination in the paddock environment. The results suggests that isolation of animals as soon as a Salmonella infection is indicated by clinical symptoms of diarrhea could be a means of reducing and controlling the spread and persistence of Salmonella in outdoor organic pig production environments.

Verocytotoxin-producing Escherichia coli in wild birds and rodents in close proximity to farms

Article Abstract:

Wild birds and rodents may become infected from farm animals or vice versa, suggesting a possible role in verocytotoxin-producing Escherichia coli (VTEC) transmission. It is however possible that wild animals and birds act as vehicles for VTEC transmission between farms or supporting the persistence of VTEC infections in domestic animals.
