| Coronaviruses are enveloped, positive-stranded RNA, belongs to the Nidovirales order, Coronaviridae family and are classified into three groups. Groups 3a and 3c comprising the avian coronaviruses. They are worldwide in distribution and can cause respiratory, enteric and in some cases hepatitis and neurological diseases in a wide variety of animals, resulting in economic losses to breeders and breeding. In this study, we describe an outbreak of diarrhea in a herd of capybaras found in the city of Piracicaba, São Paulo, Brazil. The animals had sudden symptoms of anorexia, profuse and watery diarrhea, yellowish or greenish, dehydration, weight loss, sharp and twisting of limbs leading to death in less than a week, mostly weaned and with an age of three... |

| Avianpox is a highly contagious disease infecting both commercial and wild birds, causing great damages to breeders and breeding. Caused by DNA viruses of the family Poxviridae, genus Avipoxvirus, if manifest through 3 forms, cutaneous, diphtheric and septicemic. In June 2003, during illegal commercialization of Brazilian birds, 800 wild birds (Paroaria dominicana, Sporophila caerulescens and Sporophila albogularis) were apprehended and being forwarded to the CRAS (Wild Animals Recovery Center), Tietê Ecological Park. After one month, birds presented cutaneous lesions in the beak and feet and anorexia, emaciation, locomotion difficulties, diarrhea, dehydration and death. Among the 800 birds, 500 died and 40 these (15 Paroaria dominicana, 15 Sporophila... |

| Circovirus are viral agents that cause disease in avian species. The main clinical symptoms of the disease are immunosuppression and, in young birds feather disorders. In neonates, the disease is known as "black spot" and characterized by abdominal enlargement, hepatobiliar congestion and failure to thrive. Also, it wasobserved in adult infected birds with other symptoms and clinical signs, such as enteritis, sinusitis, rhinitis, tracheitis, bronchopneumonia, myocarditis, nephritis, splenitis, dyspnea, anorexia, depression leading to high mortality. In April 2008, 317 saffron finch were apprehended during an illegal commercialization and were forwarded to the Wild Animals Recovery Center of the Tiete Ecological Park. Subsequently, 101 (31.66%) died and 20... |

| The barn-owl (Tyto Alba) and striped-owl (Rhinoptynx clamator) belong respectively to the families Tytonidae and Strigidae. Avian paramyxoviruses have been isolated from a variety of species of wild and domestic birds wordlwide causing diverse clinical symptoms and signs. Paramyxoviruses belong to the family Paramyxoviridae and Avulovirus genus, including nine serotypes (APMV 1 to 9). The lymphoid leukosis is a retrovirus-induced neoplasia. The avian retroviruses belong to the Retroviridae family and to the Alpharetrovirus genus. Coronaviruses can cause respiratory and enteric disease in several species of birds. They belong to the Coronaviridae family and to the groups 3a e 3c. In this study, we describe the presence of viruses in four owls, two barn owls... |
