150 people had participated in the public survey, and their age ranges from 16 to 50 and the gender of the participants is relatively equal, making the statistical data relatively effective and reliable. According to the survey (Figure 1), only 25% of the patients with serious diarrhea caused by Staphylococcus aureus infection choose to go to hospital while the others just take some medicine by themselves.

For patients who take medicine by themselves, over 50% of them will take antibiotics as their first choice, Smecta being the second. This phenomenon revealed a widespread use of antibiotics in daily enteritis treatment, which may not be a wise option due to a series of side effects and the well-known existence of antibiotic resistance.

In addition to investigating the current condition of antibiotic overuse, we also asked what other measures people will take to prevent such diseases. For the majority of people, suggested by the data above, they tend to take yogurts as a preventive solution rather than Chinese medicine, giving us some clues to our project design. It is likely for us to insert the gene of antimicrobial peptides into a certain kind of probiotics. Thereafter, the genetically modified probiotics can be made into a daily yogurt product that can later be manufactured, which is likely to benefit thousands of patients who suffer from serious bacterial enteritis.
