Abstract

A highly specific Salivaricin A (SalA) induction system is used to directly detect the presence of SalA in the saliva of humans who either harbor populations of SalA-producing Streptococcus Salivarius or who have been colonized with the SalA2-producing probiotic S. Salivarius K12. Four additional variants SalA2 to Sal A5 are identified.

Abstract

A study was conducted to analyze the activities of Bacillus thuringiensis insecticidal crystal proteins against three species of sheep blowfly. Results indicated that the susceptibility of insect larvae to B. thuringiensis crystal proteins correlated with their midgut environment. Findings also showed that its specificity correlated with the presence of specific toxin receptors on the insect midgut epithelium.
