Seroprevalence of Corynebacterium pseudotuberculosis and Toxoplasma gondii in s...
Moura,Gabriela Hémylin Ferreira; Lelis,Ivana Cristina Nunes Gadelha; Rocha,Célio Souza da; Oliveira,Ilanna Vanessa Pristo de MedeirosABSTRACT: The present study was conducted to investigate in 20 extensive sheep farms for the seroprevalence of Corynebacterium pseudotuberculosis (n=402) and Toxoplasma gondii (n=228). Enzyme-linked immunosorbent assay (ELISA) was used for the detection of antibodies to C. pseudotuberculosis/T. gondii. It was observed that C. pseudotuberculosis showed the highest prevalence in the region (34.07%) with statistic...
Transmission of caprine arthritis encephalitis virus between sheep
Lima,Carla Caroline Valença de; Ayres,Maria Consuêlo Caribé; Pinheiro,Raymundo Rizaldo; Costa,Joselito Nunes; Souza,Thiago Sampaio deABSTRACT: This study was conducted to evaluate caprine arthritis encephalitis virus (CAEV) transmission among sheep using 15 lambs that were distributed in 2 experimental groups. The exposed group consisted of 10 lambs that remained with their mothers, who were experimentally infected with CAEV. The non-exposed group was characterized as the control group and was comprised of 5 lambs that remained with their CA...
Sheep infection by caprine lentivirus
Souza,Thiago Sampaio de; Pinheiro,Raymundo Rizaldo; Lima,Carla Caroline Valença de; Brito,Roberta Lomonte Lemos de; Azevedo,Dalva Alana Aragão deSUMMARY 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 polymer...
Evaluation of caprine arthritis-encephalitis virus transmission in newborn goat...
Rodrigues,Apoliana de Sousa; Pinheiro,Raymundo Rizaldo; Brito,Roberta Lomonte Lemos de; Oliveira,Leandro Silva; Oliveira,Eduardo Luiz deABSTRACT: Caprine arthritis encephalitis causes considerable losses in goat production. The main form of the caprine arthritis encephalitis virus transmission is through the ingestion of colostrum or milk from infected females. However, some transmissions cannot be explained in this manner. Therefore, this study aimed to evaluate transplacental transmission of caprine arthritis encephalitis virus. Blood samples...
Small ruminant lentiviruses: economic and productive losses, consequences of th...
Azevedo,Dalva Alana Aragão de; Santos,Vanderlan Warlington Souza dos; Sousa,Ana Lídia Madeira de; Peixoto,Renato Mesquita; Pinheiro,Raymundo RizaldoABSTRACT: Small ruminant lentiviruses, caprine arthritis encephalitis virus, and Maedi-Visna virus cause diseases that result in significant productive losses, mostly in dairy animals. These viruses belong to the Retroviridae family, Lentivirus genus, and constitute a heterogeneous group, which may generate implications for the diagnosis and control of small ruminant lentiviruses. Losses caused by them are asso...
In vivo evaluation of antiseptics and disinfectants on control of Caseous Lymph...
Santiago,Lauana Borges; Pinheiro,Raymundo Rizaldo; Alves,Francisco Selmo Fernandes; Santos,Vanderlan Warlington Souza dos; Rodrigues,Apoliana de SousaThe objective of this experiment was to evaluate the efficacy of iodine tincture at 10% and sodium hypochlorite at 2.5% applied into the abscess of animals affected by Caseous Lymphadenitis (CL). Eighteen ewes were used, assorted into three groups: one treated with iodine tincture at 10% (IT), another one with sodium hypochlorite at 2.5% (SH) and the last group underwent the conventional treatment (CT).
