Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Staphylococcal enterotoxins (SEs) are the main reason for the pathogenicity of Staphylococcus aureus, and finding a suitable inhibitory agent against their production is necessary for the food industry. The aim of this study was the finding a mixture of Lactobacillus strains with the highest anti-enterotoxigenic activity (AEA) against the production of A and B enterotoxins from S. aureus grown on medium including sub-minimum inhibitory concentrations of cell-free supernatant (CFS) of three Lactobacillus species using by real-time PCR and statistical method of mixture design. Results showed the antibacterial activity (AA) of CFS of Lactobacillus strains on S. aureus was higher than their microbial suspensions. Among the Lactobacillus isolates evaluated in this study, CFS of L. brevis isolated from fermented olive had higher AA against S. aureus and its A and B enterotoxins production. A synergistic inhibitory effect was observed between CFSs of L. brevis isolated from fermented olive, L. plantarum isolated from fermented olive and L. brevis isolated from pickled garlic. The highest AEA was observed by treatment with a mixture containing 45% CFS of L. brevis isolated from fermented olive, 27% CFS of L. plantarum isolated from fermented olive, and 28% CFS of L. brevis isolated from pickled garlic.
