13. Presence of antibodies against H5, H7 and H9 influenza A virus in wild birds in the State of São Paulo, Brazil
Although the natural reservoirs of the avian influenza (AI) virus have been extensively studied in many countries, there is a clear lack of information on this subject in South America, particularly in Brazil. The objective of this study was to conduct a serological survey for H5, H7 and H9 antibodies to AI-subtype viruses in wild birds in the state of São

14. Health assessment of raptors in triage in Belo Horizonte, MG, Brazil
Falconiformes (n=82), Strigiformes (n=84) and Cathartiformes (n=14) at a triage center (CETAS-Belo Horizonte, IBAMA, Brazil) were examined between 2008 and 2010 . No bird was reactive at hemagglutination-inhibition (HI) for antibodies against Mycoplasma gallisepticum (Mg). Two Caracara plancus (2/68) had HI titers (16-32) against Newcastle disease virus. No

16. Investigation on Newcastle Disease Virus (NDV), Infectious Bursal Disease Virus (IBDV) and Avian Poxvirus (APV) in magellanic penguins in Southern region of Brazil
To investigate the exposure of the Newcastle disease virus (NDV), infectious bursal disease virus (IBDV) and avian poxvirus (APV) in Magellanic penguins found on the beaches in Southern regions of Brazil, the frequency of serum antibodies was estimated in 89 samples taken during 2005 and 2006. All the penguins were negative for the presence of antibodies aga

17. Inquéritos soroepidemiológicos em eqüinos da região Sul do Brasil para detecção de anticorpos anti-flavivírus de interesse em saúde pública / Seroepidemiologic study in horses from southern Brazil to the detection of anti-flavivirus interest in public health
As arboviroses são enfermidades que acometem o homem, equinos e outras espécies animais causando na sua maioria das vezes infecções que vão desde assintomáticas até neurológicas. Os Flavivirus são importantes arbovírus encontrados no Brasil. Foi realizado um estudo descritivo a partir de inquéritos sorológicos em 1775 equinos para detecção de a

18. H9N2 avian influenza virus antibody titers in human population in fars province, Iran
Among the avian influenza A virus subtypes, H5N1 and H9N2 viruses have the potential to cause an influenza pandemic because they are widely prevalent in avian species in Asia and have demonstrated the ability to infect humans. This study was carried out to determined the seroprevalence of H9N2 avian influenza virus in different human populations in Fars prov

19. Seroprevalence survey of H9N2 avian influenza virus in backyard chickens around the Caspian Sea in Iran
Since 1998, an epidemic of avian influenza occurred in the Iranian poultry industry. The identified agent presented low pathogenicity, and was subtyped as an H9N2 avian influenza virus. Backyard chickens can play an important role in the epidemiology of H9N2 avian influenza virus infection. Close contact of backyard chickens with migratory birds, especially

The arboviruses are diseases that affect humans, horses and other animal species causing in the majority of cases an asymptomatic infection to neurological disorders. The Flaviviruses are important arbovirus found in Brazil. A descriptive study was conducted from serological surveys in 1775 horses for detection of anti-Flavivirus antibodies in the State of P

22. Níveis de anticorpos contra o vírus da cinomose canina e o parvovírus canino em cães não vacinados e vacinados
Antibody titres to canine distemper virus (CDV) and canine parvovirus (CPV) were measured in 132 dogs: 80 had been vaccinated at least once, 22 had not been vaccinated, and 30 had unknown vaccination history. Serum antibody titers were measured by means of serum neutralization (CDV) or hemagglutination inhibition (CPV). Serum CDV titers >20 and serum CPV tit

23. Síntese de derivados de D-galactose inibidores potenciais de interação lectina-carboidrato
Lectins are proteins involved in carbohydrate recognition and their interaction is important in many natural and pathogenic events, as immunological response, fertilization, embryogenesis, infection and cancer metastasis. Hence, studies aimed at antiadhesion therapy with natural and synthetic mono- or multivalent carbohydrate derivatives show promising resul

24. Detection of of porcine parvovirus (PPV) in swine fetal tissues / Pesquisa da presença de parvovirus suino (PVS) em tecidos de fetos de suinos
Swine female reproductive quality is mainly measured by return to estrus, litter size, abortion, stillbirth and mummies. Porcine parvovirus (PPV) transplacental infection is associated to fetal death at different gestacional age, and mostly with fetal mummification due to abscence of fetal immunecompetence in early pregnancy. In late gestational age, immunec
