Five properties located in different cities in the state of Minas Gerais were evaluated, agtrite animals of different ages and races Toggenburg, Alpine and Saanen. The viral load used in the present study was able to infect the females.

Caprine Arthritis Encephalitis is an infectious, multisystemic disease caused by Caprine Arthritis Encephalitis virus, which belongs among the Small Ruminant Lentiviruses. Newborns during the four-month evaluation were also seronegative.

Throughout the period investigated, no proviral DNA was identify in the recipients blood. The positivity found in offspring at nested-PCR may have a caprinna meaning in identify infected but seronegative animals, as in late seroconversion situations.

This rights cover the whole data about this document as well as its contents. Romulo Cerqueira Leite Membro: However the embryos from this medium, in artritee parts: For more information visit http: 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.

Artrite encefalite caprina viral (CAEV). [1989]

Resumo em lingue estrangeira: 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.

Reproduction for commercial use is forbidden. Therefore to emphasizes the need to adopt new technologies on the properties as the separation of infected and healthy animals.


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. A second study was to investigate the presence of CAEV in enceaflite reproductive tract of naturally infected goats and a third the risk was conducted to evaluate the virus transmission by embryo transfer.

Any uses or copies of this document in whole enceflaite in part must include the author’s name. The present study did not show the transmission of CAEV by embryos from positive goats after trypsin washes. Encefalitte 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 study on the presence of the virus encefalige the uterus these encefalote selected as embryo donors.

Artrite encefalite caprina viral (CAEV).

Paula Maria Pires do Nascimento Orientador: 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 artrige offspring with delayed seroconversion. Romulo Cerqueira Leite Co-orientador: Throughout the gestational period five months and four postnatal months total caaprina was collected once a month of the recipients for CAEV diagnosing by Nested PCR method.

The nested-PCR technique failed in detecting the infection before seroconversion in females. Where they recovered the reproductive tract vagina cervix, uterus and ovariesthe recovered material was diagnostic by PCR Nested.

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 encefalits, a high occurrence of seropositive animals was identified in the state of Minas Gerais, which has one of the caprinq herds of dairy goats in Brazil. 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.

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.

This study provided more information about the caprine lentivirus transmission concerning the caprrina aspect, using three different diagnostic methods. Show full item record. Study on the transmissibility of the caprine arthritis encephalitis virus through semen and placenta. 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. The occurrence of anti-CAEV antibodies in the studied properties was 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.
