Abstract: The objective of this study was to demonstrate iatrogenic transmission of small ruminant lentivirus (SRLV) from goats to sheep and horizontal transmission between sheep. The study was conducted on a farm with separate goat and sheep rearing, and animals were monitored for lentivirus occurrence by clinical examination and testing by immunoblotting (IB), agar gel immunodiffusion (AGID), and nested polymerase chain reaction (nPCR). Positive results had not been observed in the sheep flock until this study. Conversely, virus positive dairy goats were known. For this reason, the farm performed the caprine arthritis-encephalitis (CAE) control program. The study was designed with a sheep group that presented positive animals for SRLV by nPCR. It was verified that three newborn animals in this group were rejected by their mothers and consequently received milk from the goat herd. These three animals remained with another 20 sheep of the same age, totaling 23 animals. After one year, during monitoring, 11 of the 23 animals in the group presented positive results in the nPCR and three demonstrated seroconversion by IB. Of the animals that had received goat milk, two had positive results in the nPCR and IB. The 11 animals positive in the nPCR were followed and it was verified that five animals did not present further positive results in the nPCR, nor seroconversion; two continued presenting positive results in the nPCR but were negative in the IB and AGID and four were positive in the nPCR, IB, and AGID. Thus, it was possible to demonstrate iatrogenic interspecific infection and the occurrence of horizontal caprine lentivirus transmission among sheep. [Infecção de ovinos pelo lentivírus caprino]. Resumo: O objetivo foi demonstrar a transmissão iatrogênica de lentivírus de pequenos ruminantes (LVPR) de caprinos para ovinos e a transmissão horizontal entre ovinos. O estudo foi conduzido em propriedade com criação não consorciada de caprinos e ovinos, monitorada para ocorrência de lentiviroses, a partir de acompanhamento clínico e testes de immunoblotting (IB), imunodifusão em gel de agarose (IDGA) e reação em cadeia da polimerase do tipo nested (nPCR). Resultados positivos no rebanho ovino não haviam sido observados até então. Por outro lado, sabia-se que o rebanho caprino leiteiro era positivo. Por este motivo, a propriedade realizava programa de controle da artrite-encefalite caprina (CAE). O estudo foi delineado em um lote de ovinos que apresentou animais positivos para LVPR na nPCR. Verificou-se que três animais neonatos deste lote foram rejeitados por suas mães e por isso receberam leite do rebanho caprino. Estes três animais permaneceram com outros 20 ovinos de mesma faixa etária, totalizando 23 animais. Após um ano, durante a realização do monitoramento, dos 23 animais do lote, 11 apresentaram resultados positivos na nPCR e três demonstraram soroconversão por IB. Dos animais que haviam recebido leite do rebanho caprino, dois tiveram resultados positivos na nPCR e no IB. Os 11 animais positivos na nPCR foram acompanhados, verificando-se que cinco animais não apresentaram mais resultados positivos na nPCR, nem soroconverteram; dois continuaram apresentando resultados positivos na nPCR, mas negativos no IB e IDGA e quatro apresentaram-se positivos na nPCR, no IB e no IDGA. Dessa forma, foi possível demonstrar a infecção interespecífica de forma iatrogênica e a ocorrência de transmissão horizontal do lentivírus caprino entre ovinos.

Cattle imported from the Iberian Peninsula spread throughout America in the early years of discovery and colonization to originate Creole breeds, which adapted to a wide diversity of environments and later received influences from other origins, including zebu cattle in more recent years. We analyzed uniparental genetic markers and autosomal microsatellites in DNA samples from 114 cattle breeds distributed worldwide, including 40 Creole breeds representing the whole American continent, and samples from the Iberian Peninsula, British islands, Continental Europe, Africa and American zebu. We show that Creole breeds differ considerably from each other, and most have their own identity or group with others from neighboring regions. Results with mtDNA indicate that T1c-lineages are rare in Iberia but common in Africa and are well represented in Creoles from Brazil and Colombia, lending support to a direct African influence on Creoles. This is reinforced by the sharing of a unique Y-haplotype between cattle from Mozambique and Creoles from Argentina. Autosomal microsatellites indicate that Creoles occupy an intermediate position between African and European breeds, and some Creoles show a clear Iberian signature. Our results confirm the mixed ancestry of American Creole cattle and the role that African cattle have played in their development. |
