Natural infection in ovarian structures by bovine herpesvirus 1: molecular and ...
Pereira, Emílio César Martins; Costa, Eduardo Paulino da; Silva Júnior, Abelardo; Mendes, Vívian Rachel de Araújo; Santos, Giancarlo Magalhães dosNeste trabalho foi avaliada a presença do DNA viral, por meio da Reação em Cadeia da Polimerase (PCR), no tecido ovariano, nos oócitos, líquido folicular e sangue de vacas naturalmente infectadas. Também foi avaliado o perfil sorológico dos animais amostrados. Foram coletadas amostras de soro, sangue, tecido ovariano, líquido folicular e complexo cumulus-oócitos de 147 animais abatidos em frigorífico não vacina...
Evaluation of the antiviral activities of Bacharis dracunculifolia and querceti...
Ferreira, Caroline Gracielle Torres; Campos, Mateus Gandra; Felix, Daniele Mendes; Santos, Marcus Rebouças; Carvalho, Otávio Valério deEquid herpesvirus 1 (EHV-1) is a pathogen of high economic importance in equine breeding operations around the world. EHV-1 infection causes respiratory, neurologic and reproductive disease. The absence of an efficient therapy has caught the attention of the scientific community and the therapeutic activities of natural products with its antivirals effects might be effective for the disease's treatment. Herein ...
Gengivostomatite crônica felina com infecção por calicivirus: relato de caso
da Silva, Aline Silvestrini; Hertel, Fernanda Campos; Lotério, Mayara Pereira; Cota, Jéssica Miranda; Rodrigues, Bruna GiannakopoulosFeline chronic gingivostomatitis (FCGS) is an oral inflammatory condition that frequently affects felines. Its etiology is not well defined, but several viral agents are thought to be involved. Several therapeutic protocols have been described, yet treatment response is often variable, and the therapeutic success is transient with an unpredictable duration. Therefore, the therapeutic strategy needs to be tailor...
Antibodies against Bovine herpesvirus 1 in dairy herds in the state of Espirito...
Santos, Marcus Rebouças; Ferreira, Hanna Carolina Campos; Santos, Marcos Antônio dos; Saraiva, Giuliana Loreto; Tafuri, Natália FilardiO herpesvírus bovino 1 (Bovine herpesvirus 1 - BoHV-1) causa grandes prejuízos econômicos à pecuária bovina mundial, por comprometer os sistemas respiratório e reprodutivo de bovinos de corte e leiteiros. Nas últimas décadas, os registros de casos clínicos ocasionados pelo BoHV-1, no Brasil, mostram que têm aumentado gradualmente, o que torna importante o delineamento de estudos que mostrem a distribuição da in...
Evaluation of a synthetic peptide from the Taenia saginata 18 kDa surface/secre...
Guimarães-Peixoto, Rafaella Paola Meneguete; Pinto, Paulo Sérgio Arruda; Santos, Marcus Rebouças; Polêto, Marcelo Depólo; Silva, Letícia FerreiraBovine cysticercosis is a zoonotic infection widely spread throughout Brazil, creating a burden on hygiene maintenance and the economy. Diagnosis of cysticercosis usually relies on post mortem inspection of carcasses in slaughterhouses. This detection method provides only low sensitivity. Recent advancements have improved the performance of serologic tests, such as ELISA, providing greater sensitivity and speci...
Utilization of phage display to identify antigenic regions in the PCV2 capsid p...
Santos, Marcus Rebouças; Assao, Viviane Sisdelli; Salgado, Rafael Locatelli; Fietto, Juliana Lopes Rangel; Bressan, Gustavo CostaPorcine circovirus 2 (PCV2) is associated with a series of swine diseases. There is a great interest in improving our understanding of the immunology of PCV2, especially the properties of the viral capsid protein Cap-PCV2 and how they relate to the immunogenicity of the virus and the subsequent development of vaccines. Phage display screening has been widely used to study binding affinities for target proteins....
Evaluation of the genetic variability found in Brazilian commercial vaccines fo...
Saraiva, Giuliana Loreto; Santos, Marcus Rebouças; Pereira, Claiton Gonçalves; Vidigal, Pedro Marcus Pereira; Fietto, Juliana Lopes RangelInfectious bronchitis virus (IBV) is currently one of the most important pathogens in the poultry industry. The H120 and Ma5 are the only viral strains approved by the Brazilian government as the constituent of vaccines. Despite the systematic vaccination in Brazil, IBV has not yet been controlled and diseases associated with this virus have been reported in vaccinated chickens. Here, we investigated the geneti...
Surveillance of neutralizing antibodies against Bovine Herpesvirus 1 in cattle ...
Santos, Marcus Rebouças; Ferreira, Hanna Carolina Campos; Carvalho, Otávio Valério de; Bulos, Luiz Henrique Silva; Nascimento, Vinicio AraujoThe aim of this study was to investigate the presence of neutralizing antibodies against bovine herpesvirus 1 (BoHV-1) in 722 non-vaccinated animals from eight properties that use different farming systems (extensive, semi-confinement and confinement). Serum samples were subjected to neutralization tests in order to search for anti-BoHV-1 antibodies. Serological results were categorized as negative, low titer, ...
