Successful colonization in the small intestines is indicated by prolonged shedding of vibrios in coproculture. Therefore, to test for colonization, we tested for shedding of vibrios in coproculture. We found that there was a significant difference in shedding between P-5 and the positive control. The coproculture of the rabbits vaccinated with P-5 had a shedding time of 8 days, whereas the shedding time in the rabbits vaccinated with the positive control was 5.5 days.

Which sentences should be omitted from the below Results section?
Biofilm growth. Biofilm formation starts with bacterial attachment to the surface, then progresses to auto-aggregation, micro-colonies formation, maturation, and eventually cell detachment. To determine the dynamics of the biofilm growth and the effect on membrane performance in reverse osmosis, biofilm was grown on membranes for 6, 12, 24, or 48 hours post inoculation. Subsequently, specific biovolumes of the viable cells and dead cells were determined (Table 1). Micro-colonies of bacteria were observed 6 hours after inoculation. After 12 hours some dead cells were observed. 24 hours after inoculation, more dead cells were found, and crevices and holes appeared in the biofilm, probably due to detachment of cells and small ag-gregates from the biofilm. These rapid changes in biofilm structure do not follow the previously reported biofilm formation stages (12, 43). Possible reasons for this rapid change in biofilm structure could be a depletion of nutrients after 24 hours. In addition, previous studies used rich growth me-dia (12, 43), whereas in our study minimal media was applied.
