FIGURE 1 Bar chart shows the mean of relative abundance of each taxa in both faecal and oral samples. Orange bars indicate faecal samples and blue bars indicate oral samples. Faecal bars represent the mean and error bars the standard error (n=31), while oral bars represent the mean and error bars the standard error (n=99). The most common abundance of bacteria in faecal sample were Bacteroides and while the most common abundance of bacteria in oral sample were Streptococcus. The mean of abundance is obtained by summing up the abundance of each taxa and divide it by the total number of samples in each faecal and oral samples respectively. Standard error is obtained by dividing standard deviation of each taxa with total number of samples that have been square rooted in each faecal and oral samples respectively. Result for culture dependent and independent in oral cavities: FIGURE 2 Bar chart represents the percentage of student cohort in each taxa for culture dependent and independent data. The orange bars indicate culture dependent data while the blue bars indicate culture independent data. Culture independent data detects all aerobic, anaerobic, facultative anaerobes as well as obligate anaerobes but culture dependent cannot identified any of these obligate anaerobes. However, culture independent data does not detect Staphylococcus. Percentage of student cohort is obtained by counting the amount of each taxon identified (only relative abundances of bacteria that are
