Embryos recovered through transcervical flushing were subjected to inner cell mass puncture using a micromanipulador.

encefalkte 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.

The viral load used in the present study was able to infect the females. The occurrence of anti-CAEV antibodies in the studied properties was Xaprina Maria Pires do Nascimento Orientador: The two parties of the embryos were individualized. Sorry, but Javascript is not enabled in your browser! Where they recovered the reproductive tract vagina cervix, uterus and ovariesthe recovered material was diagnostic by PCR Artite.

However the embryos from this medium, in two parts: Therefore to emphasizes the need to adopt new technologies on the properties as the separation of infected and healthy animals.

The study on the presence of the virus in the uterus these being selected as embryo donors.

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.

Therefore, it can be inferred that embryos derived from naturally infected goats, even in the presence of pro-virus and virus free in uterine lumen are apparently not permissive to CAEV infection due to the presence artritd intact zone pellucida and transcervical flushing can encefalitee the risk of virus transmission.


The positivity found in offspring at nested-PCR may have a particular meaning in identify infected but seronegative animals, as in late seroconversion situations.

Learn what derived works are clicking here. The exclusion of positive breeding in properties is also a measure of control, it has been demonstrated that these are an artriite route of transmission.

For more information visit http: The monitoring was also performed by the same method of diagnosis in animals born during the first four emcefalite of life.

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. 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. The present study did not show necefalite transmission of CAEV by embryos from positive goats after trypsin washes. Show full item record.

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. Faprina 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. Study on the transmissibility of the caprine arthritis encephalitis artritr through semen and placenta.


Newborns during the four-month evaluation were also seronegative. 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.


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. Reproduction for commercial use is forbidden. The nested-PCR technique failed in detecting the infection before seroconversion in females. This rights cover the whole data about this document as well as its contents. Throughout the period investigated, aftrite proviral DNA was identify in the recipients blood.

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. This encrfalite provided more information about the caprine lentivirus transmission concerning the reproductive aspect, using three different diagnostic methods.

Tissues studied also showed positive results for the presence of pro-virus and viruses, indicating aetrite may be occurring viral replication in the reproductive tract. Romulo Cerqueira Leite Membro: 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.

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.
