| dc.description.abstract | In Study 1 predilection sites for cysticerci of Taenia solium were determined by calculating relative cyst density for different carcass sites. The psoas muscle was found to be an important site for localization of cysliccrci in pig carcasses followed by muscles of Triceps brachii. tongue, internal masseters, external masseters, diaphragm and heart as important sites for localisation of cystcerci in pigs. Based on these findings, all of these muscle groups/organs are proposed as predilection sites of T. solium in Tanzanian pigs and thus their examination should be mandatory for efficient routine inspection of pig carcasses. Tongue examination survey results from Chunya and Iringa Rural Districts, (Study II), showed that the two districts are endemic for porcine cysticercosis with prevalences of 7.6% and 8.4%, respectively. Structured questionnaire interviews identified factors associated with the disease prevalence in both Chunya and Iringa Rural Districts were free- ranging of pigs, home slaughtering of pigs and pork not being inspected. While in Chunya and Iringa Rural Districts lack of latrine and barbecuing were found a risk factor, respectively. In Study III, conducted in Mgeta Division, ante mortem tongue examination of 609 pigs and post mortem pork inspection of 124 carcasses found that they were all negative. These results instigated the interview study of relevant local parties, the findings of which were, none of the respondents reported having ever seen any cysts in pork or pigs. Availability, maintenance and use of latrines was found to be very high throughout Mgeta Division (97.6%) and in every village pigs are required to be kept totally confined. Health Centre data indicated that there were no cases of taeniosis, cholera or shigellosis reported during the last five years (1998 - 2002). There is an urgent need to transfer the important lessons from Mgeta districts such as Chunya and Iringa Rural. In Study IV sensitivity and specificity of the tongue examination and antigen ELISA [Ag-ELISA] tests were compared in local Tanzanian pigs and it was observed that Ag-ELISA was more sensitive [3.6 times] than tongue examination and therefore would be more appropriate for surveillance in Tanzanian pigs. | en_US |
