Abstract
The present study determined the prevalence of Cysticercus cellulosae in pigs of Jammu region along with determining the role of porcine feed in disease development. A total 600 pork samples were examined and 7 (1.16%) were found positive. Association of porcine cysticercosis with different epidemiological factors was examined, breed and husbandry practices were observed to be statistically linked with disease in pigs. The cyst detected was morphologically analyzed to reveal a scolex with armed rostellum having 27 hooks and four suckers. The suckers and hooks, when subjected to micrometry revealed mean length and width of 273.33 ± 12.12µm and 228.31 ± 9.51µm, respectively, whereas the length of hooks (large and small) were 154.66 ± 10.72µm and 113.33 ± 9.84µm, respectively. Histopathologically the cyst revealed the infiltration of inflammatory cells (primarily lymphocytes) inside and in adjacent, along with marked fibrosis and vasculitis. A total of 25 porcine feed samples including 15 farm feed and 10 sewage samples were screened for Taeniid eggs. The observed results revealed that porcine feed is not the major root cause of infection of Cysticercus cellulosae for pigs, as only a single sewage sample was found positive for Taeniid eggs and egg size observed showed a size of 40.4 ± 4.26µm×28.8±3.02µm on micrometry.
