Non-pathogenic intestinal protozoa are single-celled parasites commonly found in the intestinal tract but never associated with illness. They do not harm the body, even in people with weak immune systems.They are found only in lumen of the intestinal tract. They are not found in the cells that line the intestines, and they do not spread to other parts of the body. Every year there are thousands of cases of food-poisoning and gastroenteritis reported in Ireland although reported cases constitute only a small proportion of actual cases. These infections encompass pathogens from viral, bacterial and protozoan aetiologies. However, most reported cases are likely to be viral in origin. Very young children are especially prone to rotavirus infection. In the last two years, hundreds of cases of viral gastroenteritis were caused.
Several non-pathogenic protozoa inhabit the intestinal. The non-pathogenic protozoa can be divided into two groups: amebae and flagellates. Protozoa are a diverse group of unicellular eukaryotic organisms, many of which are motile. They are restricted to moist or aquatic habitats. That can be flagellates, ciliates, and amoebas. To help prevent the spread of the disease around the home:
•Wash hands thoroughly with soap and hot running water for at least 10 seconds after using the toilet or changing a baby's diaper, and before handling food.
•Clean bathrooms and toilets often; pay particular attention to toilet seats and taps.
•Avoid sharing towels or face washers.
