Interactions
This parasite, Cryptosporidium parvum,
has interactions with many species with humans being greatly
affected. One main parasitic interaction this parasite has with
humans is that it can cause the disease Cryptosporidiosis. This
disease causes the human to have severe diarrhea, weight loss,
electrolyte imbalance, and abdominal pain that could be long
term depending upon your immune system’s status (Upton, 2008).
Individuals under the age of two are more likely to obtain this
disease, but everyone is potentially at risk (Virginia
Department of Health, 2013).
The disease can be found everywhere throughout the world and
even within our very own state. In fact, in Milwaukee,
Wisconsin, 403,000 cases were reported in 1993 with this
epidemic being one of largest waterborne outbreaks in the United
States ever recorded (NZFSA, 2010). This is crazy to think
about, right?
C. parvum is very common among animals such as
white or
black tailed deer, elk,
fish,
birds, domestic animals, and especially calves; also parasitic
interactions. In fact, one hundred and fifty five species of
mammals have been reported to have this parasite interaction
with Cryptosporidium parvum (NZFSA, 2010). This parasite has an
outer shell that protects it and keeps it alive outside the body
for some period of time, though it can’t replicate outside the
intestines.
This parasite is also found within various types of raw food
including fruits (such as
grapes or
cranberries which get washed before being eaten), vegetables, milk, and meat that can then
affect a potential host (Duffy and Moriarty, 2003). Though
Cryptosporidium parvum cannot grow within food, it will survive
and become harmful for consumers.
