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 ...
Inhibition of herpes simplex virus 1 (HSV-1) and poliovirus (PV-1) by bacterioc...
Cavicchioli, Valéria Quintana; Carvalho, Otávio Valério de; Paiva, Janine Cerqueira de; Todorov, Svetoslav Dimitrov; Silva Júnior, AbelardoBacteriocins have unusual inhibitory activity, including antiviral properties, and this can be exploited to give alternative applications. Semi–purified bacteriocins of six lactic acid bacteria (LAB) strains isolated from goat milk (two Lactococcus lactis: GLc03 and GLc05, and four Enterococcus durans: GEn09, GEn12, GEn14 and GEn17) were tested for cytotoxicity in Vero cells (50% Cytotoxicity Concentration: CC5...
Verification of natural infection of peridomestic rodents by PCV2 on commercial...
Pinheiro, Albanno Leonard Braz Campos; Bulos, Luiz Henrique Silva; Onofre, Thiago Souza; Gabardo, Michelle de Paula; Carvalho, Otávio Valério deThe porcine circovirus-2 (PCV2) is the main agent responsible for porcine circovirus associated diseases (PCVAD). Few studies have been done regarding PCV2 infection in other species. The purpose of this study was to investigate the occurrence of PCV2 infection in the peridomestic rodent species Mus musculus and Rattus rattus on commercial pig farms in Brazil. Immunohistochemistry assay demonstrated PCV2 in the...
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, ...
