Health assessment of captive tinamids (Aves, Tinamiformes) in Brazil.
Ninety-five (95) captive tinamids (Aves, Tinamiformes) of species Crypturellus obsoletus (brown tinamou), Crypturellus parvirostris (small-billed tinamou), Crypturellus tataupa (Tataupa tinamou), Crypturellus undulatus (undulated tinamou), Rhynchotus rufescens (red-winged tinamou), and Tinamus solitarius (solitary tinamou) were evaluated for diseases of mandatory control in the Brazilian Poultry Health Program (PNSA). Antibodies were detected by serum agglutination test (SAT) in 4 birds for Mycoplasma gallisepticum (MG) and in 27 birds for Salmonella Pullorum (SP) and Salmonella Gallinarum (SG). However, by hemagglutination inhibition (HI), sera were negative to MG and Mycoplasma synoviae (MS). Bacteriology was negative for SP and SG. No antibody was detected by HI to avian paramyxovirus type 1. However, antibodies to infectious bursal disease virus were detected in 9.4% (9/95) by ELISA. Fecal parasitology and necropsy revealed Capillaria spp. in 44.2% (42/95), Eimeria rhynchoti in 42.1% (40/95), Strongyloides spp. in 100% (20/20), Ascaridia spp., and unknown sporozoa in small-billed tinamou. Ectoparasites were detected in 42.1% (40/95) by inspection, and collected for identification. The louse Strongylocotes lipogonus (Insecta: Phthiraptera) was found on all Rhynchotus rufescens. An additional four lice species were found on 14 individuals. Traumatic lesions included four individual R. rufescens (4/40, 10%) with rhinotheca fracture, one with mandible fracture and three with posttraumatic ocular lesions (3/40, 7.5%). One C. parvirostris had phalangeal loss, another had tibiotarsal joint ankylosis and another had an open wound on the foot. Results suggest that major poultry infections/ diseases may not be relevant in tinamids, and that this group of birds, as maintained within distances for biosecurity purposes, may not represent a risk to commercial poultry. Ecto- and endoparasites were common, disseminated, and varied; regular monitoring of flocks is recommended for best performance.
