Metric Options: CountsSelecting 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
Background: Yersinia enterocolitica is a gram-negative bacteria and one of the most important food-borne bacteria that causes yersiniosis. Several studies have investigated various species of this gastrointestinal pathogen in food and water sources. Although Olivier salad is a ready-to-eat and easily available cold food, it is highly susceptible to microbial contaminations. This study aims to investigate the presence of Yersinia spp., especially the pathogenic Yersinia enterocolitica in Olivier salad. Methods: In this cross-sectional descriptive study, 150 specimens (traditional and industrial Olivier salad) were collected and tested for the presence of Yersinia spp. Using the Iranian National Standard No. 4556. Obtained data were analyzed statistically using descriptive statistics in IBM SPSS. Results: Yersinia spp. contamination was found in only 6% of traditional specimens (6 out of 100). Based on biochemical reactions, four isolates of Yersinia enterocolitica and two isolates of Yersinia intermedia were identified from six Yersinia isolates. The biotype of Yersinia enterocolitica was investigated, and three strains of biotype 1A and one strain of biotype 1B were identified. The human pathogenic serotype was not found in the serotype analysis. Conclusion: The study results showed that specimens of traditionally prepared Olivier salad were contaminated with Yersinia spp. Yersinia enterocolitica is the most prevalent species as expected, and the analysis of the strains of this species revealed that it also contains other biotypes, including the highly pathogenic biotype 1B.
