How C. parvum Works
The two most critical factors in
preventing C. parvum outbreaks
Nydam and Mohammed 2005
• Cannot grow or multiply in the
environment
• Needs host for oocytes to proliferate
• Hygiene of calf rearing area
• Prevent entry of newly infected calves in
high density areas

How does C. parvum survive in the
host animal? (cont)
• invagination of the host cell plasma
membrane, which extends along the
surface of the sporozoite and eventually
completely surrounds it,
• “Occupation": formation of a
“parasitophorus” vacuole where the
parasite undergoes further development in
a unique intracellular but extra-cytoplasmic
location.
How does C. parvum survive in the
host animal?
Crucial steps in the pathogenesis of
cryptosporidium
• Ingestion of oocyte
• Attachment to intestinal epithelial cells
• Invasion of host intestinal epithelial cells
(Sporozoites attach to host cells by their
anterior pole).

Preventative Dietary Therapy
• If attachment is critical to C parvum
survival:
• Then:
– Prevent attachment!
• Find something else that the bacteria like
to attach to that is:
– not part of the anatomy,
– inactivates the pathogen
– can be removed
Effect of Celmanax® on C. parvum infectivity in
bovine and porcine intestinal epithelial cells in-vitro
Rural Technologies, Brookings SD
• Sporozoites of C. parvum were pretreated with
Celmanax®, BSM or buffer and then allowed to infect
cells
• First slide shows the degree of attachment of treated
sporozoites to the intestinal cells
• Second slide shows the degree of infectivity of
intestinal cells by treated sporozoites

• 16 calves 10-12 days old randomly assigned to
treatments
• Treatments –
Control pasteurized whole milk

• Treatments fed for 5 days
• Fecal samples were taken at the start and finish of the

Conclusions
Celmanax® Liquid
On Farm Trial
• Calves supplemented with Celmanax® Liquid
demonstrated 3 fold less oocyte shedding within
5 days after supplementation.
• Fifteen day fecal and dehydration scores were
significantly less for calves supplemented with
Celmanax® Liquid.

• 17 calves on Celmanax® Liquid and 22 calves
on control treatment. Calves on Celmanax®
were lighter at the start of the trial compared to
control calves.
• Calves were fed 22-20 CMR plus free (amplifier
max) 18% starter and free choice water.
• Calves had tested positive for crypto at the start
of the trial. But no crypto related data was
collected.
• Mortality, and wt gain was recorded every week
and ADG at the end of the trial.

• Mortality was reduced in the Celmanax®
treatment.
• No significant wt. difference was observed
