“…At Cacha Pregos the presented positivity can be related to the contact with migratory birds as well as to the acquisition of birds from the aviary pole of Feira de Santana, city near Cacha Pregos. The serologic research at backyard chicken breeding shacks and ostrich related by SALES (2007), FERNANDES et al (2009 and MATTOS (2013), at the Feira de Santana/Bahia region, showed the presence of antibodies against the Newcastle disease virus, even without any report of the birds' vaccination, strengthening the hypothesis that the birds got in contact with the virus (low-virulence strains), representing a risk factor for the poultry culture at the studied region. Nonetheless, the RT-PCR and viral isolation results were negative, proving that the birds were not eliminating the virus at the moment of sample collection.…”

The poultry industry has been considered one of the most efficient agricultural activities, placing Brazil in the ranking of the largest producers of chicken meat. However, a threat to the poultry production chain is the entrance of Newcastle disease virus (NDV) in the country, which would bring huge economic and social losses. Monitoring of the virus was conducted in domestic poultry (Gallus gallus domesticus) farms on the migratory birds landing sites Mangue Seco and Cacha Pregos between 2013 and 2014 to control Newcastle disease (NCD) in these locations. Activities in health education, filling the questionnaire to define the sanitary profile of the farms, georeferenced registration and collection of blood samples, cloacal and tracheal swabs of the backyard birds were the epidemiological surveillance actions performed. A total of 133 serum samples were analyzed in Mangue Seco and 81 in Cacha Pregos. The results showed that both Mangue Seco (63.4%) and Cacha Pregos (88.9%) presented reactive animals for the NDV. The results of real-time polymerase chain reaction (RT-PCR) and viral isolation analyses were negative, proving that the domestic poultry were not eliminating the virus at the time of sample collection. The high percentage of reactive animals by indirect ELISA test in both epidemiological units studied suggests the presence of NDV circulating lentogenic strain, since there was no death registration and the birds did not have characteristic symptoms of the disease.

“…Many of these birds, being they migratory, wild or domestic, are natural hosts and transmit various infectious viruses, such as Influenza A, West Nile and Newcastle Disease (Fernandes et al, 2010, Flores & Weiblen, 2009.…”

“…The Newcastle Disease virus (NDV), which belongs to the family Paramyxoviridae and genus Avulavirus, has various pathogenic strains (Arns et al, 2007;Farkas et al, 2009;Fernandes et al, 2010). The history of Newcastle Disease began in 1926 with the description of a highly pathogenic disease in two geographical areas on opposite sides of the world, Newcastle-onTyne in England and the island of Java in Indonesia (Kraneveld, 1926;Doyle, 1927;Alexandre, 2001).…”

“…NDV infections have been detected in at least 241 avian species, representing 27 of the 50 orders of the class (Alexander & Manvell, 2004), and many serotypes have been isolated from asymptomatic wild aquatic birds (Alexander, 1995). Today this disease is distributed around the globe, since the lack of specific legislation on international trade in birds in the 90s enabled the worldwide dissemination of the virus (Farkas et al, 2009, Fernandes et al, 2010. Phylogenetic analysis has separated NDV into two sister clades, class I and II, which contain several genotypes each.…”

The Pantanal is the world's largest wetland biome with a seasonal flood pulse that attracts a great diversity of birds, many of which are migratory. Birds can be natural reservoirs Influenza A, West Nile and Newcastle Disease viruses. However, the occurrence of carriers for these viruses in the Pantanal was not verified yet. The present study evaluated the occurrence of natural infection by Influenza A, WN and ND virus of birds in the municipality of Poconé, a subregion of the Pantanal in the state of Mato Grosso, Brazil. A total of 76 birds belonging to 11 orders and 20 families were captured using mist nets. The most representative order was Passeriformes, followed by the other nine orders, which included Columbiformes, Psittaciformes, Charadriiformes and Anseriformes. The most representative family was Thamnophilidae, with 16 individuals (21.0%), followed by the family Tyrannidae with 10 individuals (7.6%) and the family Furnariidae, with eight individuals (10.5%). The bird species were identified, and cloacal and tracheal swab samples were collected. The samples were subjected to RNA extraction and tested for the presence of the three agents by real-time polymerase chain reaction (qRT-PCR). All the sampled birds were considered healthy, had no clinical sign of infection, and were tested negative for the three viruses. Based on our findings, we can conclude that Influenza, West Nile and Newcastle Disease viruses were absent from the samples in this region of the Pantanal wetlands during the period of this study.
