PUBLIC HEALTH AND PREVENTION STRATEGIES

B. hominis is often associated with other pathogens—recently researches have suggested that the increase in bacteria during diarrhea might enhance the growth of B. hominis (Leder, Zierdt). If this is in fact the case, techniques to manage other GI parasites (including sanitation, water treatment, antiobiotic regimens) would also effectively combat B. hominis (Blastocystis hominis Infections). However, the thick-walled B. hominis cysts have shown resistance to chlorine, so heat inactivation and filtration are likely to be more effective (Amin, Diaz, John, 36).

Prior to any large-scale measures, however, the medical community must come to a consensus about the organism itself—whether it is a pathogen or mere commensal. At this point, experts generally agree that a thorough search must be made to exclude other pathogens and other known causes of gastrointestinal disease before prescribing medication for B. hominis. Given our current knowledge, the public health community stands to achieve more measurable gains by focusing on pathogens more pressing than Blastocystis hominis.
