13. Efeito do enxerto ósseo córtico-esponjoso no reparo de falha cortical ulnar de Galinhas domésticas. 2010. / Effects of cortical-cancellous bone graft in repair of failed ulnar cortex of domestic chickens. 2010.
As fraturas em aves representam um desafio para os cirurgiões, pois suas características ósseas peculiares associadas ao tipo de trauma a que geralmente essas espécies são expostas determinam fraturas cominutivas ou até mesmo a perda de segmentos ósseos. O objetivo do presente estudo foi avaliar o efeito do enxerto ósseo córtico-esponjoso na osteog�

14. Etiology and immunology of infectious bronchitis virus
Infectious bronchitis virus (IBV) of chickens is currently one of the main diseases associated with respiratory syndrome in domestic poultry, as well as with losses related to egg production. The etiological agent is a coronavirus, which presents structural differences in the field, mainly in the S1 spike protein. The immune response against this virus is co

15. Evaluation of infectivity, potential of transmission, reservoirs state and humoral immune response of pigeon (Columba livia) experimentally infected with low and high pathogenicity strains of Newcastle Disease virus (N.D.V.) of high and low pathogenicity. / Avaliação da infectividade, transmissibilidade, estado de portador (reservatório) e da resposta imune humoral de pombos (Columba livia) submetidos à infecção experimental frente a estirpes do vírus da doença de Newcastle (V.D.N.) de alta e baixa patogenicidade.
Newcastle Disease (ND), is a highly contagious disease of viral etiology and several bird species are susceptible this disease. The domestic pigeon (Columba livia), has been regarded as a host and disseminating agent of ND. Therefore, a study was carried out in order to evaluate the responses of pigeons naturally or experimentally infected with this pathogen

16. Inheritance of a new albino mutation in Brazilian free-range black chickens
A genetically recessive albino mutation, which inhibits pigment development in the eyes, skin, and feathers of domestic chickens from Brazil, is described. This mutation appeared in a flock of completely black chickens of a private breeder. There are no information on the origin, breed, or specific line of the birds. Pigment inhibition is apparently complete

17. Isolamento e tipifícação genotípica de Clostridium Perfringens em frangos de corte.
Clostridium perfringens is an anaerobic Gram-positive bacterium which causes gaseous gangrene and enterotoxaemias in humans and domestic animals besides being the primary cause of necrotic enteritis in poultry. Clostridium perfringens strains were isolated 171/250 (68.4%) from the intestinal content of broiler chickens sampled in a slaughterhouse in Pará de

18. Estudo da Transmissão Experimental de Borrelia anserina (Sakharoff, 1891) por Argas (Persicargas) miniatus Koch, 1844 e Avaliação Comparativa de Parâmetros Clínicos e Hematológicos em Gallus gallus Linnaeus, 1758 / A Study on the Experimental Transmission of Borrelia anserina (Sakharoff, 1891) by Argas (Persicargas) miniatus Koch, 1844 and a Comparison of Clinical and Hematological Parameters
Avian spirochetosis is an acute septicemic disease, cosmopolite, of a variety of avian species caused by Borrelia anserina (Sakharoff, 1891). This spirochete is usually present in the blood of infected birds during the early stages of the disease. The present study assesses the experimental transmission of B. anserina by infected ticks Argas miniatus, observ

19. Serological evidence of hepatitis E virus infection in different animal species from the Southeast of Brazil
Serological evidence of hepatitis E virus infection (HEV) has been observed in both humans and different animal species living in non-endemic areas, suggesting that animals could be important reservoir for virus transmission to man. Antibodies to HEV have been detected in some Brazilian population groups. Nevertheless, sporadic cases of acute HEV infection h

20. Entomological aspects of Chagas' disease transmission in the domestic habitat, Argentina
OBJECTIVE: To study the risk of Trypanosoma cruzi domestic transmission using an entomological index and to explore its relationship with household's characteristics and cultural aspects. METHODS: There were studied 158 households in an endemic area in Argentina. Each household was classified according to an entomological risk indicator (number of risky bite

21. Triatoma infestans in Greater Buenos Aires, Argentina
The Health Administration Agencies of many municipalities in Greater Buenos Aires (GBA) receive frequent reports on triatomines in houses. The aim of this work was to identify and describe the dispersal foci of Triatoma infestans in an urban neighborhood of GBA, and contribute to the knowledge of the epidemiological situation in the region. In June 1998, pot

22. Phylogenetic distribution of the novel avian endogenous provirus family EAV-0.
A new family of related endogenous proviruses, existing at 50 to 100 copies per haploid genome and distinguishable by remarkably short long terminal repeats, has been described for domestic chickens (Gallus gallus subsp domesticus). In this communication, by using Southern blot analysis and probes derived from both internal viral sequences and locus-specific

23. Response of Ligated Intestinal Loops in Chickens to the Enterotoxin of Clostridium perfringens
Approximately 45-cm length of jejunoileum of 7-week-old chickens was found to be responsive and suitable for testing the enterotoxin of Clostridium perfringens by the ligated intestinal loop technique. Injections of 20 to 30 μg of enterotoxin per loop caused positive response of fluid accumulation. Chickens were found to be more convenient and economical fo
