Full Text Available Cacing pita ini adalah parasit dalam usus halusmanusia, dan sebagai inang antaranya adalah sapi. Penyakit infeksi yang disebabkan oleh cacing pitaTaenia saginata dikenal dengan nama Taeniasis. Investigations of the epidemiology of bovine cysticercosis and human taeniasis were carried out in the county of Wittstock from till The analysis was based on the examination of human faeces, sewage and sewage sludge, the registration of infested humans, anticestodica consumption, number of infested cattle, areas for squirting out sewage, fodder supply areas and location of cattle.
These data were mapped. There is a direct connection between the prevalence of Cysticercus bovis in more than 50 per cent of the infested cattle of the county of Wittstock and the squirting out of the sewage of the county town. The proportion of infested humans and infested cattle is 1: or 1: , respectively. The prevalence of adult tapeworms is 0. Performance of the ELISA test for the diagnosis of cysticercosis using experimentally and naturally cattle infected with metacestode of Taenia saginata.
Full Text Available The bovine taeniasis-cysticercosis complex can be defined as a set of pathological changes caused by the adult form of Taenia saginata in humans and their larval form in animals Cysticercus bovis. Data on the occurrence of bovine cysticercosis comes from the records of veterinary inspection of meat in slaughterhouses under fiscalization, where some positive cases may go unnoticed, especially in moderate infections. So, it is relevant the use of serological tests that have greater sensitivity than the post-mortem routine exams.
Studies have shown the possible application of the ELISA test as a tool for epidemiological studies of the parasitosis and in the identification of animals with cysts. The aim of this study is to determine the detection threshold of the indirect ELISA test, using experimentally and naturally infected animals in detecting cases of cysticercosis.
However, when using the cut-off of 1 and 2 added with 3 SD, the test sensitivity dropped, represented by As for the samples from experimentally infected animals, using the cut-off 1 and 2 added with 2 SD the sensitivity was It is important to take into account the right choice of control sera used in the ELISA test, whereas, according to its application, it is necessary to increase the sensitivity or specificity.

Full Text Available The epidemiology of Taenia saginata in some parts of Asia is confusing, in that beef does not appear to be the source of infection. In some areas, beef is either not available or not eaten raw, whereas pork at times is eaten uncooked. In light of this situation, we have exposed pigs and other animals to infection with strains of T. We also fed the eggs to 10 Holstein calves, 17 Sannean goats, and 4 monkeys Macaca cyclopis. Therefore, these strains of pig seem to be favorable animal models for experimental studies of T. Cysticercosis in cattle and its public health implications in Mekelle Key words: Cysticercosis, Cysticercus bovis , occurrence, taeniasis, Taenia saginata ,.
Bovine cysticercosis is the infection of the cattle caused by Cysticercus bovis and consumption of the raw or undercooked meat results in human taeniasis.
The Morphology and Pathogenicity of the Bladder Worms: Cysticercus cellulosae and Cysticercus bovis
Recent hybridization between Taenia asiatica and Taenia saginata. Five Taenia tapeworms collected from humans in Tibetan Plateau, Sichuan, China, where three species of human Taenia are sympatrically endemic, were examined for the mitochondrial cox1 gene and two nuclear genes, ef1 and elp. Phylogenetic analyses of these genes revealed that two adult worms showed nuclear-mitochondrial discordance, suggesting that they originated from hybridization between Taenia saginata and Taenia asiatica. One of two worms had T.
The worm having T. In another worm, the ef1 locus was heterozygous with a T. Self-fertilization is the main reproductive method of the genus Taenia. Since self-fertilization represents a type of inbreeding, each locus in the offspring would become homozygous over generations with genetic drift. The fact that some nuclear loci are still heterozygous means that hybridization might have occurred recently.

Partial sequences of the DNA polymerase delta pold gene from Taenia saginata -like adult worms were sequenced. Phylogenetic analysis revealed that pold gene sequences were clearly divided into two clades, differing from each other in five to seven nucleotides.

Experimental single and trickle infections of cattle with Taenia saginata : Studies of immunodiagnosis. Two groups of 12 calves were given either a single infection dose of 30, Taenia saginata eggs group A or trickle infected with 12 x T saginata eggs group B. The calves were killed 16, 22 or 54 weeks after infection and the numbers of viable and dead parasites were counted by slicing Characterization of immunogenic proteins of Cysticercus tenuicollis of goats.

Analysis of genetic diversity in different geographical populations of T. However, there are few reports of the genetic variability of T. We report the genetic diversity of T. Fifty-three haplotypes were identified from 98 sequences. Phylogenetic tree and haplotype network analyses revealed that global isolates of T. Taenia saginata from western Thailand clustered in groups C1, C2 and D, and populations from the northeast and western Thailand were found to be genetically distinct. Taenia saginata isolates in Lao PDR and Thailand were also found to be genetically diverse but the degree of genetic differentiation was low.
Taenia saginata populations from Lao PDR and northeastern Thailand are genetically distinct from the population in western Thailand and it is proposed that T.
