Provedor de dados: 77
Autores: Mutua,P. M; Gicheru,M. M; Makanya,A. N; Kiama,S. G.
In mammals, surface respiratory macrophages (SM) are known to play a foremost role in protecting the respiratory system by providing first line of defense through engulfing pathogens and particulate matter respired with air. It has been reported that the pulmonary cellular defense system of domestic birds is inadequate. In particular, low number of SM and even lack of the cells in a healthy avian respiratory system have been associated with susceptibility of domestic birds to respiratory diseases. In an endeavor to resolve the existing controversy, the quantitative and qualitative attributes of the surface respiratory macrophages of the domestic duck and of the domestic rabbit were compared under similar experimental conditions. Quantitatively, the rabbit...

Autores: Catroxo,M. H. B; Martins,A. M. C. P. F; Petrella,S; Milanelo,L; Aschar,M; Souza,F; Nastari,B.D.B; Souza,R.B.
Diseases caused by avian paramyxovirus (APMV) occur in commercial, captive and wild birds worldwide, demonstrating the significant economic and ecological importance of these agents. Paramyxoviruses belong to the Paramyxoviridae family, Paramyxovirinae subfamily and Avulavirus genus. During the period 2000 to 2011, stool and small intestine samples of 1647 birds species were sent to the Laboratory of Electron Microscopy, Biological Institute of São Paulo, Brazil, for diagnosis of viral agents. The samples were processed by negative staining (rapid preparation) and resin embedding techniques. Under the transmission electron microscope by negative staining technique, in 294 (17.8%) samples of 1647 were visualized paramyxovirus particles pleomorphic, roughly...

Oology and the evolution of thermophysiology in saurischian dinosaurs: homeotherm and endotherm deinonychosaurians?
Provedor de dados: 84
Autores: Grellet-Tinner,Gerald.
The origin of avian endothermy is a long-held question the answer of which cannot be provided by first level observations. Oological and reproductive characters have collectively provided a new source of data useful for phylogenetic analyses and paleobiological inferences. In addition, the observations of reproductive and oological evolutionary trends in saurischian dinosaurs lead to the interpretation that not only, the thermophysiology of these dinosaurs progressively became more avian-like but after re-examination allows to infer that deinonychosaurians represented here by three troodontids and one dromaeosaurid might already have developed an avian-like endothermy, thus predating the rise of avians. These results based on reproductive traits are...

Provedor de dados: 89
Autores: Pacheco,BHC; Nakagi,VS; Kobashigawa,EH; Caniatto,ARM; Faria,DE; Faria Filho,DE.
ABSTRACT The objective of this study was to determine the optimal dietary concentration of zinc and manganese on the performance characteristic and the requirement of these trace minerals derived from organic sources for broilers from 1 to 42 days of age. In experiment 1, zinc was evaluated, whereas manganese was evaluated in experiment 2. In each experiment, 320 males chicks were distributed in iron mesh metabolic cages (0.9m x 0.7m x 0.5m), according to a completely randomized experimental design in eight treatments with five replicates of eight birds each. In experiment 1, zinc sulfate was included at 0,60 and 100mg/kg and zinc methionine at 20, 40, 60, 80 and 100mg/kg. In experiment 2, manganese sulfate was added at 0, 65 and 105mg/kg and manganese...

Ovarian radiographic and direct measurements of Japanese Quail ( Coturnix coturnix japonica ) submitted to light restriction
Provedor de dados: 45
Autores: Albuquerque,M.; Guedes,R.; Dornbusch,P.; Laskoski,L.; Mangini,P.; Lange,R.
ABSTRACT Often, in pet birds, any stimulus to lay eggs is unwanted in order to reduce reproductive diseases and disorders. The objectives of this study were: to determine the time necessary to promote ovary involution after an eight hour photoperiod using laying Japanese quails (Coturnix coturnix japonica); to connect the ovarian radiographic measurements with egg production; and to compare these measurements with direct ovary data obtained at necropsy. Birds were separated into three groups: 12h/24d (control group - 12h photoperiod for 24 days), 8h/24d and 8h/36d (8h photoperiod for 24 and 36 days). After euthanasia, all cadavers were x-rayed to measure ovary length and height. Birds were necropsied to measure ovarian length and weight. Results:...

ABSTRACT The aim of this study was to evaluate the use of polyamide 12 intramedullary rods in osteotomized humerus in cockerels (White Plymouth Rock) and analyze, by radiography and histopathology, bone consolidation and the formation of bone callus. Ten cockerels were subjected to transverse osteotomy of the right humeral diaphysis followed by the insertion of polyamide 12 locked rods, with two nails in each bone fragment. Radiographies obtained at the immediate pre and post-operative period, and every 7 days for 3 months revealed no perioperatory complications. Radiography revealed a radiopaque bone callus between the 4th and 5th week post-surgery. Histopathology detected an amphophylic material (polyamide 12 rod) in the intramedullary region and the...

Botulism in non-ruminants in Brazil
Provedor de dados: 65
Autores: Oliveira Júnior,Carlos Augusto de; Silva,Rodrigo Otávio Silveira; Olinda,Roberio Gomes; Lobato,Francisco Carlos Faria.
ABSTRACT: Botulism is an intoxication caused by the ingestion of neurotoxins secreted by Clostridium botulinum and characterized by progressive flaccid symmetrical paralysis. Among non-ruminant animals, avian species and dogs are the most commonly affected by botulism, while horses and pigs are less-commonly diagnosed with the disease. Despite the importance of this disease in animals, the Brazilian literature only includes case studies and outbreak descriptions. The aim of this study was to review the main features and to provide recent data on the occurrence of botulism in non-ruminants in Brazil.

Autores: Silva,Rodrigo Otávio Silveira; Ferreira Junior,Francisco Carlos; Marques,Marcus Vinícius Romero; Oliveira Junior,Carlos Augusto; Martins,Nelson Rodrigo da Silva; Lobato,Francisco Carlos Faria.
The aim of this study was to isolate, genotype and evaluate the antimicrobial susceptibility of Clostridium perfringens found in species Tinamidae, Cracidae and Ramphastidae in Brazil. C. perfringens was isolated in 13 (5%) out of 260 swab samples and five (8.3%) out of 60 stool samples. All strains were classified as C. perfringens type A, and nine (50%) were positive for the beta-2 toxin-encoding gene. No strains were positive for the necrotic enteritis toxin B-like (NetB)-encoding gene. All isolates were susceptible to penicillin, metronidazole and vancomycin, whereas four (22.2%), five (27.8%) and 13 (72.2%) strains were considered resistant to erythromycin, oxytetracycline and lincomycin, respectively.
