Abstract

Cysticercosis zoonotic parasitic disesase caused by Taenia solium larva, is a major public healthproblem. Cysticercosis results from the development of larval tapeworms in humans harboring adult T.solium or from ingesting soil containing eggs shed in the feces of humans, in areas where there are nolatrines. Humans are accidental intermediate hosts and pigs are the normal intermediate hosts. Clinicallythey are most serious when located in the central nervous system or in the eye where they persist formonths to years. Cysticercosis occurs worldwide primarily in developing country where pigs are raised,pork consumed and poor sanitation allows pigs’ access to human faeces. The occurance of the diseases isexpected to increase in relation to the growing demand for pork in those countries. In Indonesia cyticercosisis still a very important health problem, especially in Bali and Papua. The majority of the populations inBali and Papua are Hindus and Protestants/Catholics, respectively, so pork widely consumed in thoseislands. This brief review summarizes the present situation and problems of cysticercosis in animal inBali and Papua. Epidemiological data of the diseases were obtained from several sources.

Abstract

Cysticercus bovis is the larval stage of Taenia saginata, the bovine tapeworm. The infection of thislarval in cattle musculature causes Bovine cysticercosis or Cysticercosis bovis.  Bovine cysticercosis is foundworldwide, but mostly in developing countries, where unhygienic conditions, poor cattle managementpractices, and the absence of meat inspection are common.  The adult Taenia infection in man is referredto as taeniasis.  Taenia saginata taeniasis is also found almost all over the world.  The prevalence ofTaenia saginata taeniasis has reported up to 27.5% in Gianyar Bali. In order to control the diseases,vaccination against the larvae stages in cattle of Taenia saginata may play an important role in controllingthe disease in the endemic regions.  The aims of the present study were to prepare and to investigate theimmunogenic protein as vaccine candidate for controlling  Cysticercus bovis infection in in Bali cattle.Cysticercus protein from the cyst fluid was firstly used to immunize mice and the mice sera were thencollected. Cysticercus proteins then analyzed using sodium dodecyl sulfate-gel electrophoresis (SDS-PAGE).All cysticercus proteins were then visualized by Commasie blue staining. The proteins were also transferredonto nitrocellulose membrane and the immunogenic proteins were visualized by Western Blotting usingimmune sera raised in mice.  By Commasie blue staining, a total of 17 proteins were detected with themolecular weight of 14,86 kDa -122,40 kDa from the smallest to the largest. As many as 7 immunogenicproteins with the molecular weights of 16.81 kDa; 19.22 kDa; 20.98 kDa; 27.41 kDa; 34.02 kDa; 38.31 kDa;and 54.94kDa were detected.

Abstract

The aim of this research was to determine immune response of mice against vaccines derived fromcyst fluid of Taenia saginata. The study was conducted using four BALB/c mice aged 6 weeks as experimentalanimals. All experimental animals were vaccinated intra peritoneal with Taenia saginata cyst fluidemulsified in Freund’s adjuvant. Immune response in the mice was determined by detecting antibodiesusing ELISA and by the presence of lymphocytes through evaluation of blood smear. The results showedthat the cyst fluid of Taenia saginata was antigenic and capable of inducing antibody responses that weredetected by ELISA. Mean antibody titers obtained in the results of the first, second, third, and fourth ofvaccination was 3.3 units; 17.9 units; 21.2 units; and 72.1 units; respectively. Evaluation of blood smear ofvaccinated mice showed an increase in the percentage of lymphocytes after vaccination with an average66.75%, compared with the average of lymphocytes before vaccination which was 40.75%. Further researchis still required in experimental animals by vaccination followed by challenge test with Taenia saginataeggs.

Abstract

The biological studies of Taenia saginata metacestoda development have been conducted in Bali cattle. Two Bali cattle were used as the samples; each was infected by 500.000 T. saginata eggs.  Cattle I and II were slaughtered and examined for the presence of T. saginata metacestodas,103 and 131 days post infection, respectively. All visceral organs and skeletal muscles were thoroughly inspected; incisions and inspection were done following the routine meat inspection.  In cattle I, was observed 534 metacestodas in the skeletal muscles, heart, and diaphragm.  The metacestodas had the form an oval bladder measuring around 3 x 2 mm. While, in cattle II was observed 2,249 metacestodas in the skeletal muscles, heart, diaphragm, and tongue measuring around 4 x 3 mm.  The finding of the present study may indicate that in Bali cattle the oncospheres of T. saginata might reach its optimal development (in to T. saginata metacestoda) in four months post infection.
