EXPERIMENTAL INFECTION OF CATTLE WITH EGGS OF Taenia solium (Infecção experimental de bovinos com ovos de Taenia solium)
A study was performed in Piraquara, Parana, Brazil during 1994-1996 to evaluate the possibility of bovines participation in the epidemic chain of the Taenia solium. Six gravid segments of T. solium were obtained from a non medicated patient. Holstein bovines were infected with 40,000 eggs of T. solium. The infection rate was 100%. A total of 44 cysticerci were recovered: 18 (40.9%) alive and 26...
متن کاملCalculation of the efficacy of vaccines against tick infestations on cattle† Cálculo de eficácia de vacinas contra a infestação de carrapatos nos bovinos
Cattle ticks are responsible for great economic losses in cattle farming worldwide, and their main control method, chemicals, has been showing problems, whether resulting from the development of resistant strains of ticks or environmental contamination. Research studies directed toward developing vaccines against ticks are emerging. One way to evaluate those vaccines is to calculate the percent...
متن کاملBovine in vitro embryo production protocol: does it really influence embryo cryotolerance? Protocolo de produção in vitro de embriões bovinos: este realmente influencia a criotolerância dos embriões?
The protocol of in vitro production (IVP) of bovine embryos is one of the critical factors determining embryo viability after cryopreservation. In this study were used two differents protocols to produce IVP bovine embryos, with variations in protein source, oocyte/zygote density per media volume, with the aim to determine the in vitro and in vivo embryo survival after vitrification using hand-...
متن کاملTransplacental transmission of Anaplasma marginale in beef cattle chronically infected in southern Brazil Transmissão transplacentária de Anaplasma marginale em bovinos de corte cronicamente infectados no sul do Brasil
In this study, we have investigated the incidence of transplacental transmission of Anaplasma marginale in chronically infected cows with no history of acute anaplasmosis during gestation. In addition, we evaluated various techniques for detection of transplacental transmission of A. marginale. Blood samples were collected from 30 cows at three different periods: at the time of artificial insem...
متن کاملUsefulness of serological ELISA assay for Taenia saginata to detect naturally infected bovines Utilização de teste sorológico ELISA para a detecção de bovinos naturalmente infectados por Taenia saginata
Bovine cysticercosis, a cosmopolitan disease caused by Taenia saginata, leads to economic losses due to carcass devaluation at slaughter. Sanitary inspection at slaughterhouses, the routine diagnostic method in Brazil, lacks the necessary sensitivity to detect the mildly infected cattle that are typically encoutered in Brazil. In this study we have tested cattle sera from animals diagnosed as p...
