Human microbiota have a significant impact on the health of individuals, and reciprocally, lifestyle choices of individuals have an important effect on the diversity and composition of microbiota. Studies assessing microbiota knowledge among the public are lacking, although it is hypothesized that this knowledge can motivate healthier behavior. Hence, this study aimed to measure microbiota knowledge among university students, and the effect of this knowledge on behavioral beliefs. A descriptive cross-sectional study was conducted among students from various fields of study enrolled at the University of Jordan, using an online questionnaire. The questionnaire consisted of 3 parts: demographics, general knowledge of microbiota, and behavioral beliefs related to microbiota. Four hundred and two responses were collected from verified university students. Participants were divided into two groups depending on whether they took a formal microbiology course (45 h) or not. Results from those two groups were compared using appropriate statistical methods. Results showed that most participants, even those who did not take a formal microbiology course, displayed good knowledge of what microbiota is and how they can be influenced by personal and environmental factors. Participants who took a microbiology course had significantly higher microbiota knowledge scores and were more aware of the effect of antibiotics on microbiota. Participants’ behavioral beliefs regarding their antibiotic use, but not their diet and lifestyle choices, were affected by their knowledge of microbiota. The study indicates that disseminating knowledge regarding microbiota and microbiology in general, can improve behaviors related to antibiotic use.

Although COVID-19 vaccines have been available in Jordan for more than a year, Jordan suffers from a low vaccination rate. The aim of this study was to explore attitudes towards recent issues in vaccination among university students in Jordan. We adopted a cross sectional study design using an online questionnaire distributed in a Jordanian university with a medical school chosen at random. The survey asked about COVID-19 vaccine preferences, factors affecting COVID-19 vaccine preferences, child vaccination, and booster vaccines. A total of 417 students completed the survey. Most respondents (54.7%) preferred the Pfizer vaccine, and 6.2% refused to take any vaccine. Pfizer’s efficacy against new strains is a main factor in preferring Pfizer over other vaccines (p < 0.01). Most respondents (71%) believed that vaccination is crucial to prevent COVID-19 surges from new COVID-19 strains, while 44.6% of respondents believed that children should be included in vaccination campaigns, and 70% believed that booster vaccines required more studies to prove their efficacy. Students had mixed attitudes towards many recent issues concerning COVID-19 vaccination. Studying these factors and attitudes in more depth and in different populations can pave the way towards improving vaccination rates worldwide.
