Objective: To present a more accurate method for diagnosis of Cysticercus bovis in slaughtered cattle. Project: Slaughterhouse study.
Animal: 3436 cattle.
Method: To present a more accurate method for diagnosis
of C.bovis in slaughtered cattle 1812 cattle were examined
at meat inspection using traditional method. Meanwhile by
using standard method for detection of c.bovis at meat
inspection in South Africa, Germany and England 145
cattle for each region were examined. In each method the
percentage of infection with C.bovis was determined. In
traditional method heart, external and internal master and
triceps muscles were inspected. Whereas for the method
used in Germany and England, heart, external and internal master, oesophagus, diaphragm, tongue and for that of
South Africa in addition to these, triceps was also inspected.
The best, among the method used, was selected and according to the latter 1189 carcasses were examined. If the
accuracy of selected method was statistically superior or
similar to the best method, thus it was considered as an
alternative or replacement method to the traditional
method.
Results: By examining of 1182 cattle at meat inspection
using traditional method 47 carcasses(2.6%) harboured
c.bovis in different organs, whereas using standard
method, used in Germany, England and South Africa 7.6%,
6.9% and 6.9% of examined cattle were found to be infected
with’ C.bovis. There was a significant differences between
traditional method and standard methods of three different
countries us in X2 test. Standard method used in Germany
was more accurate than the others, thus it was chosen as our
selected method by which 1189 cattle were examined of
which ninty cattle (7.6%) were found to be infected with
C.bovis, an infection rate comparable to German method.
Thus it could be suggested as an alternative or replacement to the traditional method. J.Fac.Vet.Med. Univ. Tehran.
