Surveillance of bulk raw and commercially pasteurized cow's milk from approved Irish liquid-milk pasteurization plants to determine the incidence of Mycobacterium paratuberculosis

Article Abstract:

The Food Safety Authority of Ireland (FSAI) carried out surveillance of Irish bulk milk and commercially pasteurized liquid-milk supplies to determine the incidence Mycobacterium paratuberculosis. The results show that M. paratuberculosis DNA is occasionally present at low levels in both raw and commercially pasteurized cow's milk, but as no viable M. paratuberculosis was isolated from commercially pasteurized cow's milk on retail sale in the Republic of Ireland.

Relating cell killing to inactivation of critical components

Article Abstract:

A study was conducted on the loss of CFU following a life-threatening treatment which is related to the inactivation of critical components. It was observed that the loss of CFU following heating may precede, lag behind, or coincide with the loss of the active critical component, depending on the form of the function and the number of copies of the critical component in each cell.

Specificity of a bacteroides thetaiotaomicron marker for human feces

Article Abstract:

The relative specificity of the reported marker was attempted and determined for the 542-bp amplicon in human feces, sewage and feces from nonhuman hosts and its specificity to a benchmark human Bacteroides primer set was compared. It was observed that the B. thetaiotaomicron primer set appeared to be more effective indicator of human feces than the benchmark primer set.
