Summary For the first time a survey of the prevalence of bovine brucellosis in three regions of the Democratic Republic of Somalia has been carried out. Blood sera were tested by the SAT and CFT and milk samples by the MRT. An average prevalence rate of 9.5 per cent (SAT) and 12.0 per cent (MRT) was found. There were considerable differences between regions and the reasons for this are discussed.
Brucelosis Bovina En Las Regiones Meridionales De La Reúpblica Democrática De Somalía
Resumen Una encuesta epidemilógica sobre la prevalencia de brucelosis se Ilevó a cabo por primera vez en tres regiones meridionales de la república democrática de Somalía.El suero sanguíneo se analizó mediante las pruebas SAT y CFT y las muestras de leche mediante la prueba MRT. Se encontro una prevalencia promedia de 9.5 por ciento (SAT) y 12.0 por ciento (MRT). Se encontraron diferencias considerables entre regiones lo cual se discute en el trabajo.
La Brucellose Bovine Dans Les Régions Sud De La République Démocratique De Somalie
Résumé L'existence de la brucellose bovine est signalée pour la première fois en République démocratique de Somalie. Des échantillons de sang ont été testés par les techniques du SAT et du CFT et des échantillons de lait par le MRT. 9 p. 100 par le SAT et 12 p. 100 par le MRT ont été trouvés.Il existe entre les régions de larges différences dont les raisons sont discutées.相似文献

Epidemiological studies were made on 14 farms from which, during a 2 year period, 38 cattle had been condemned at slaughter, due to massive infections with Cysticercus bovis. By on-site investigations and interviews, attempts were made to identify the transmission routes of Taenia saginata eggs from human faeces into the environment and further on to cattle. The most frequent sources of infection were found to be sludge from septic tanks illegally applied on pasture or crops, in some cases after having been mixed with animal slurry. Animals in permanently housed herds were infected through the fodder or by contamination of the indoor environment by such slurry containing Taenia eggs. Other herds were infected by grazing pastures in close proximity to municipal sewage treatment plants. In contrast to earlier Danish observations, application on farmland of sewage sludge from municipal treatment plants was not involved in any of the reported outbreaks. This apparent change coincides with the implementation of more restrictive legislation for the agricultural use of sewage sludge in Denmark. 相似文献

In March, 1973, a large feedlot near Phoenix, AZ, reported an increased incidence of bovine cysticercosis. Approximately 10% of cattle sent to slaughter from January to April, 1973, were infected with the cysticercus stage of Taenia saginata. One employee who worked at the feed mill and loaded hay in the fields was also found to be infected with T saginata. Recommendations for control of similar epizootics included educating employees about mode of transmission and improved personal hygiene, the inauguration of a surveillance program that included examination of employees prior to employment and periodically thereafter, maintenance of animal source and destination records, restriction of unauthorized personnel to critical areas, and periodic microbiologic assay of water supply. 相似文献

Bovine cysticercosis: preliminary observations on the immunohistochemical detection of Taenia saginata antigens in lymph nodes of an experimentally infected calf 下载免费PDF全文

A newly developed immunohistochemical test was used for the first time to demonstrate the presence of Taenia saginata (Cysticercus bovis) antigens in the lymph nodes of a heifer calf experimentally inoculated with Taenia saginata eggs. The new test should aid in the differential diagnosis of eosinophilic lymphadenitis in cattle. 相似文献

Vaccines against cysticercosis and hydatidosis. 总被引:18,自引:0,他引:18
The recombinant vaccines that have been developed against cysticercosis and hydatidosis in sheep and cattle are remarkable for their effectiveness and are prominent as examples of the very few non-living vaccines against parasitic diseases. Their development has been through practical application of molecular parasitology, utilising immunochemical techniques in antigen identification and recombinant DNA methods in antigen production. This brief overview discusses the contribution of molecular techniques to the successful development of recombinant vaccines against Taenia ovis, Taenia saginata and Echinococcus granulosus as well as the immunological and genomic studies that have arisen from their development. 相似文献

A sero-epidemiological study of Taenia saginata cysticercosis was carried out in adult cattle in Zambia to determine the prevalence and study the influence of the farming system on the infection rate. Serum samples were examined for circulating parasite antigen by a monoclonal-based sandwich ELISA. Thirty-eight of 628 serum samples were found positive (prevalence 6.1%). Cysticercosis was significantly more prevalent in feedlots and in traditional farming systems than in dairy farms. It is suggested that the continuous man to animal contact and the use of casual workers in feedlots may be factors that are conductive to T. saginata transmission. 相似文献
