Viral type characterization and clinical aspects of canine parvovirus in natura...
Monteiro,Kyssia; Allendorf,Susan D.; Vicente,Acácia F.; Appolinário,Camila M.; Peres,Marina G.; Cortez,Adriana; Heinemann,Marcos B.; Megid,JaneABSTRACT: Since the first isolation of canine parvovirus type 2 (CPV-2) in late 70’s new virus types as CPV-2a and CPV-2b have been emerged and becoming prevalent in natural canine population and more recently, a third subtype was identified , CPV-2c. The main purpose of this study was to detect and characterize canine parvovirus currently present in Central-West region of São Paulo state, in Brazil. Fecal samp...
Bovine herpesvirus type 1 in cumulus-oocyte complexes collected from naturally ...
Oliveira,Andre Penido; Heinemann,Marcos Bryan; Cortez,Adriana; Nascimento,Paula Maria Pires do; Leite,Romulo Cerqueira; Viana,João Henrique MoreiraAbstract: The objective of this work was to investigate the presence of bovine herpesvirus type 1 (BoHV-1) in follicular fluid and in cumulus-oocyte complexes (COC) recovered from naturally infected cows but with no clinical signs of the disease. Cows that were seropositive (n=38) or seronegative (n=8, control) to infectious bovine rhinotracheitis were selected after a serum neutralization test in microplates. ...
Canine distemper virus infection in a lesser grison (Galictis cuja): first repo...
Megid,Jane; Teixeira,Carlos R.; Cortez,Adriana; Heinemann,Marcos B.; Antunes,João M.A.P.; Fornazari,Felipe; Rassy,Fabricio B.; Richtzenhain,Leonardo J.Infectious diseases in wild animals have been increasing as a result of their habitat alterations and closer contact with domestic animals. Canine distemper virus (CDV) has been reported in several species of wild carnivores, presenting a threat to wildlife conservation. We described the first case of canine distemper virus infection in lesser grison (Galictis cuja). A free-ranging individual, with no visible c...
Etiologic diagnosis of bovine infectious abortion by PCR
Silva,Teane Milagres Augusto da; Oliveira,Raquel Gonzaga de; Mol,Juliana Pinto da Silva; Xavier,Mariana Noyma; Paixão,Tatiane Alves da; Cortez,AdrianaInfectious abortion is a significant cause of reproductive failure and economic losses in cattle. The goal of this study was to detect nucleic acids of several infectious agents known to cause abortion including Arcanobacterium pyogenes, Bovine Herpesvirus 1, Brucella abortus, Campylobacter fetus subsp. venerealis, Chlamydophila abortus, Leptospira sp., Listeria monocytogenes, Salmonella sp., Mycoplasma bovis, ...
Genetic characterization of Brazilian bovine viral diarrhea virus isolates by p...
Cortez,Adriana; Heinemann,Marcos B; Castro,Alessandra Marnie M.G. de; Soares,Rodrigo M; Pinto,Ana Maria V.; Alfieri,Amauri A.; Flores,Eduardo F.Nineteen isolates of bovine viral diarrhea virus (BVDV) from Brazil were genetically characterized through partial nucleotide sequencing and analysis of the 5'UTR region. The isolates were grouped as BVDV-1 (11/19), BVDV-2 (6/19) or "atypical" pestivirus (2/19). Among the BVDV-1, eight isolates were classified as subgenotype BVDV-1a, whereas most (4 out of 6) BVDV-2 belonged to subgenotype 2b. Two isolates from...
Comparison of four antibiotics for inactivating leptospires in bull semen dilut...
Miraglia,Fabiana; Morais,Zenaide Maria; Cortez,Adriana; Melville,Priscilla Anne; Marvullo,Maria Fernanda Vianna; Richtzenhain,Leonardo JoséInactivation of leptospires in pools of semen from three Holstein Friesian bulls, collected in an artificial vagina, was investigated. Spermatic concentration was adjusted in egg yolk citrate extender, submitted to the following treatments: A (control; without antibiotics); B (penicillin, 1,000 UI/mL - streptomycin, 1,000 µg/mL); C (amoxicillin, 1,000 µg/mL); D (ceptiofur sodium, 1,000 µg/mL); E (amoxicillin 1,...
Characterization of Aujeszky's disease virus isolates from South and Southeast ...
Piatti,Rosa Maria; Ikuno,Alice Akimi; Cunha,Elenice Sequetin; D'Ambros,Régia; Gregori,Fábio; Soares,Rodrigo Martins; Cortez,AdrianaThe genomic DNA of thirty strains of Aujeszky's disease virus (ADV) isolated in the South and Southeast regions of Brazil from 1982 to 1996 were characterized by restriction endonuclease analysis with BamHI. Twenty seven strains were isolated from pigs, 1 from cattle, 1 from cat and 1 from dog. Using a systematization previously described, the 30 ADV strains could be classified as genomic types I (n = 2) and II...
