Introduction: Salmonellosis, which is caused by nontyphoid salmonella bacteria, is one of the most common foodborne diseases, and it causes gastrointestinal infections worldwide, most of which are limited gastroenteritis that requires antimicrobial treatment. The aim of this study was to investigate the effects of echinophora platyloba extract on inhibiting the growth of Salmonella typhi, Salmonella enteritidis, and salmonella choleraesuis.
Methods: Echinophora Platyloba extract was collected in the East Azarbaijan Province in Iran in June 2015. Weeds, infected plants, and dried roots were separated and removed. After drying and grinding the plant, 100 grams of powder were weighed, and the extraction of the plant was carried out by percolation. This study tested the Minimum Inhibitory Concentration (MIC) by the broth micro dilution method and Minimum Bactericidal Concentration (MBC). All of the data were analyzed by SPSS statistical software, version 22.0. One-Way ANOVA and the Duncan test were used to compare the effect of various concentrations of the extract on each type of bacteria.
Results: Our results indicated that, in 250 mg/ml of extracts discs, the largest growth inhibition zones were formed, and they were 26.11 ± 1.16, 21.23 ± 0.89, and 19.65 ± 0.60 in S. enteritidis, S. typhi, and S. choleraesuis groups, respectively. The statistical results indicated that, in each type of bacteria, there was a statistical difference (p < 0.01) between the various concentrations of the extracts and the chloramphenicol discs. Also, it was indicated that this extract at a concentration of 150 mg/ml had a germicidal effect on S. enteritidis and S. typhi bacteria and that 250 mg/ml had a bactericidal effect on S. choleraesuis.
Conclusion: The results of this study indicated that E. platyloba extract has potential effects as antimicrobial agents.

Ethics of Publishing Case Reports: Do We Need Ethics Approval and Patient Consent?
An editorial by Dr. Mehrdad Jalalian
The worldwide spread of COVID-19 as an emerging, rapidly evolving situation, and the dramatic need of urgent medicine or vaccine, has rapidly brought new hypotheses for pathophysiology and potential medicinal agents to the fore. It is crucial that the research community provide a way to publish this research in a timely manner.
To contribute to this important public health discussion, the Electronic Physician Journal is excited to announce a fast-track procedure to help researchers publish their articles on COVID-19 related subjects that fall under the broad definition of public health, internal medicine, and pharmacology. We are especially welcome to all hypotheses about the pathological basis of the COVID-19 infection and the possible characteristics of potential medicine and vaccine. Submit your manuscript here
