Short Communication<br />
A study was undertaken to know the prevalence of Cysiticercus tenuicollis infection in slaughtered sheep and<br />
goats at Kakinada, A.P. This was recorded to be 2.36% in sheep and 1.62% in goats with an overall<br />
occurrence of 2.34% in both the ruminants. <strong>The</strong> age wise percentage of occurrence recorded in animals<br />
below and above four years of age revealed slightly higher percentage in older animals.<br />

C<br />
ysticercus tenuicollis normally occurs in greater<br />
omentum, mesentry and serosal surface of organs<br />
of domestic as well as wild ruminants (Soulsby,<br />
1982). Prevalenc of C.tenuicollis, has been earlier<br />
recorded in sheep and goats in Tamilnadu<br />
(Jayathilakan et al., 2000 and Raman and Rajavelu,<br />
2000) and Orissa (Dash et al., 2000) states in India.<br />
In view of protecting sheep and goats from<br />
C.tenuicollis infection by taking necessary preventive<br />
measures a study was undertaken to determine the<br />
prevalence of C.tenuicollis infection in slaughtered<br />
sheep and goats at Kakinada, Andhra Pradesh.<br />
<strong>The</strong> prevalence of C.tenuicollis infection was<br />
ascertained by examination of cysts found in the<br />
omentum, mesentry, peritoneal cavity and liver in the<br />
carcasses of sheep and goats slaughtered at municipal<br />
house, Kakinada in the regular meat inspection and the<br />
identification of cysts of C.tenuicollis was done at<br />
Animal Health Center, Kakinada on the basis of<br />
morphology described by Soulsby (1982) during the<br />
year 2001-2001. <strong>The</strong> prevalence of C.tenuicollis<br />
infection in relation to species and age was analysed<br />
and presented in tables I and II respectively.<br />
Out of 20,888 sheep and 798 goat carcasses examined,<br />
495 and 13 were found positive <strong>for</strong> C.tenuicollis<br />
infection in sheep and goats respectively. <strong>The</strong> overall<br />
prevalence of C.tenuicollis infection was found as<br />
2.34% in sheep and goats during the study period.<br />

<strong>The</strong> age wise prevalence revealed higher infection in<br />
the age group above 4 years (2.42% in sheep and<br />
1.77% in goats) when compared to below 4 years<br />
(2.15% in sheep and 1.28% in goats), these, however,<br />
