Pesky Parasite Is Target for New Treatment
One of the more difficult parasitic outbreaks to treat and prevent involves a single-celled protozoa. This parasite, called C. parvum, has given the medical and scientific communities a run for their money. C. parvum is a tough parasite that often settles into freshwater supplies, which are the areas where they are most comfortable and also where they do the most damage. Outbreaks of C. parvum are not just hard to stop; they’re also hard to treat. Thousands can get infected when in or near a public water supply. The good news is that scientists have recently discovered some factors that may make targeting the parasite and treating it not as complex as previously thought.
Infection with C. parvum causes symptoms like diarrhea, muscle or weight loss and malnutrition. These are particularly dangerous in the elderly or in very young children. Those who have weakened immune systems, like those with HIV/AIDS, are at risk as well. Scientists have researched some defenses that may protect people from the effects of this tiny menace.
C. parvum is not only strong but apparently pretty crafty as well: The parasite can live for a good amount of time outside the body. Parasites are not normally known to do this, or at least for not as long as this parasite does. It appears that this protozoan has a tougher exterior that protects it. Another defense mechanism it uses is its ability to hide from our immune systems, which allows it to go undetected in the intestines for longer periods of time. It destroys the natural bacterial colonies that protect our bodies. By doing this, it is able to multiply freely and continue on its destructive course.
Scientists have discovered an enzyme that allows the microbe to go undetected. By targeting this molecule, they may be able to disable C. parvum’s cloaking device. If this is the case, the immune system will then be able to spot the parasite and eradicate it. Further research and testing are still needed; however, scientists and health experts are positive that this approach will yield good results. It is possible that with this new information, we may have the upper hand against the small but terrible parasite.
