Caprine Arthritis Encephalitis is an infectious, multisystemic disease caused by Caprine Arthritis Encephalitis virus, which belongs among the Small Ruminant Lentiviruses. According the results, a caaprina occurrence of seropositive animals was identified in encsfalite state of Minas Gerais, which has one of the largest herds of dairy goats in Brazil.
Therefore to emphasizes the need to adopt new technologies on the properties as the separation of infected and healthy animals. For more information visit http: Reproduction for commercial use is forbidden.
The present study did not show the transmission of CAEV by embryos from positive goats after trypsin washes. Show full item record. This document is only for encefalige use for research and teaching activities.
Paula Maria Pires do Nascimento Orientador: 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. 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 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. Newborns during the four-month evaluation were also seronegative.
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 of intact zone pellucida and transcervical flushing can reduce the risk of virus transmission. Study on the transmissibility of the caprine arthritis encephalitis virus through semen and placenta.
The occurrence of anti-CAEV antibodies in the studied properties was 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.
Romulo Cerqueira Leite Membro: The viral load used in the present study was able to infect the females. The study on the presence of the virus in the uterus these being selected as embryo donors.
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 argrite viral inoculum.
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. 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. Where they recovered the reproductive tract vagina cervix, uterus and ovariesthe recovered material was diagnostic by PCR Nested.
The nested-PCR technique failed in detecting the infection before seroconversion in females. 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.

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.

However the embryos from this medium, in two parts: According to the results, encefallte 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 rights cover the whole data about this document as well as its contents. Romulo Cerqueira Leite Co-orientador: The positivity found in offspring at nested-PCR may have a particular meaning in identify infected but seronegative animals, as in late seroconversion enceefalite.
The monitoring was also performed by the same method of diagnosis in animals born during the first four months of life. The two parties of the embryos were individualized. Throughout the period investigated, no proviral DNA was identify in the recipients blood. Embryos recovered through transcervical flushing were subjected to inner cell mass puncture using a micromanipulador.
