Reproduction for commercial use is forbidden. The two parties of the embryos were individualized.

However the embryos from this medium, in two parts: Throughout the gestational period five months and four postnatal months total blood was collected once a month of the recipients for CAEV diagnosing by Nested PCR method. Learn what derived works are clicking here. The nested-PCR technique failed in detecting the infection before seroconversion in females.
Therefore, it can be inferred that embryos derived from naturally infected goats, even in encefallte presence of pro-virus and virus free in uterine lumen are apparently not permissive to CAEV encecalite due to the presence of intact zone pellucida and transcervical flushing can reduce the risk of virus transmission.
However it is not possible to assume the CAEV transmission to offspring indisputably, though is not discarded the possibility of infection through semen and placenta in offspring with delayed seroconversion.

Show full item record. A second study was to investigate the presence of CAEV in the reproductive tract of naturally infected goats and a third the risk was conducted to evaluate the virus transmission by embryo transfer. The viral load used in the present study was able to infect the females.
Throughout the period investigated, no proviral DNA was identify in the recipients blood. Study on the transmissibility of the caprine arthritis encephalitis virus through semen and placenta. The present study did not show the transmission of CAEV by embryos from positive goats after trypsin washes. The positivity found in offspring at nested-PCR may have a particular meaning in identify infected but seronegative animals, as in late seroconversion situations.
Five properties located in different cities in the state of Minas Gerais were evaluated, totaling animals of different ages and races Toggenburg, Alpine and Saanen. Tissues studied also showed positive results for the presence of pro-virus and viruses, indicating that may be occurring viral replication in the reproductive tract.
As control group, two CAEV-free goats were artificially inseminated with semen from same buck without viral inoculum; and other two CAEV goats inseminated with the viral inoculum. Regarding the reproductive behavior in the transmission, the objective of the present study consists of experimentally evaluate the transmissibility of caprine lentivirus in goats and their offspring through the placenta and semen. For more information visit http: The exclusion of positive breeding in properties is also a measure of control, it has been demonstrated that these are an important route of transmission.
Therefore to emphasizes the need to adopt new technologies on the properties as the separation of infected and healthy animals. The transcervical washing proved to be potentially method to reduce the virus concentration in reproductive tract, since the amount of fluid infused in the uterus could reduce the concentration of free virus in reproductive tract. Resumo em lingue estrangeira: Paula Maria Pires do Nascimento Orientador: Embryos recovered through transcervical flushing were subjected to inner cell mass puncture using a micromanipulador.
The study was conducted in steps, first a serological survey in five major producing properties of goat milk in the state of Minas Gerais, to identify the occurrence of anti-CAEV antibodies. According to the results, a high occurrence of seropositive animals was identified in the state of Minas Gerais, which has one of the largest herds of dairy goats in Brazil.

This study provided more information about the caprine lentivirus transmission concerning the reproductive aspect, using three different diagnostic methods. According the results, a high occurrence of seropositive animals was identified in the state of Minas Gerais, which has one of the largest herds of dairy goats in Brazil.
The occurrence of anti-CAEV antibodies in the studied properties was Newborns during the four-month evaluation were also seronegative. Romulo Cerqueira Leite Co-orientador: Caprine Arthritis Encephalitis is an infectious, multisystemic disease caused by Caprine Arthritis Encephalitis virus, which belongs among the Small Ruminant Lentiviruses.
