prevalence of C.tenuicollis infection in between sheep and goats for below 4 Years

(4) X test Calculated Value (0.99) is less than the table value at 5 percent level (3.84). of significance for 1 degrees of freedom for
species wise prevalence of C.tenuicollis infection in between sheep and goats for above 4 Years
C.tenuicollis infection between two animal species in
each age group of below 4Years and above 4Year
Lapage (1956) mentioned that C.tenuicollis infection
is often found in older sheep. This might be due to
decrease in resistance in older animals and increase in
the chances of exposure to infection with the
advancement of age.
Further studies are to be undertaken to determine the
extent of damage done i.e., pathogenecity in the organs
in which these cysts are present/attached particularly
the liver of these small ruminants. A study to be made
in human cases as well, simultaneously, to evaluate the
public health importance of this metacestode, if any, in
this region of A.P.
