6. INVESTIGAÇÃODE Salmonella sp. EM PSITTACIFORMES MANTIDOS EM CRIATÓRIOS COMERCIAIS E CONSERVACIONISTAS DA REGIÃO METROPOLITANA DE FORTALEZA-CEARÁ / RESEARCH Salmonella sp. MAINTAINED IN Psittaciformes in commercial houses and conservationists THE METROPOLITAN REGION OF FORTRESS-CEARÁ
Psittaciformes are the most popular pet birds in the world. Direct contact between humans and Psittaciformes is very comprehensive and the analysis of the bacterial flora of these birds is poorly known, and it can be highly pathogenic. Bacterial infections represent a major cause of enteric diseases in poultry, being the Salmonella one of the main agents inv
