Since 2000, Macrorhabdus ornithogaster "megabacteriosis" has been diagnosed in the avian diseases laboratory in a diversity of avian species and varied spectrum of disease. The disease in some species (chickens, turkeys, guinea fowls) was clinically characterized by emaciation, prostration, loss of appetite, cachexia and death, with a typically chronic course. A more acute disease was observed in finches (canary-Serinus and zebra-Taeniopygia) and budgerigars (Melopsittacus undulatus). The large rod shaped organism, visible from 100 times magnification, with and without staining, could be detected in sick and also in reasonably normal individuals of some species, such as chickens, turkeys, quails and pigeons. In rheas (Rhea americana), ostriches (Struthio camelus), canaries, zebra-finches, guinea-fowl (Numida meleagris) and budgerigars. The disease was severe, causing to up to 100% mortality. The infection could be detected in some species along with other infectious or disease problems, such as endoparasites (helminths, coccidia) and ectoparasitism (order Mallophaga or/and order Acarina). The cultivation of M. ornithogaster was successfully achieved in solid and liquid media, originated from chickens (four isolates), guinea fowl (1 isolate)...

In this paper is reported the first avian tumor that has proved transplantable to other individuals. It is a spindle-celled sarcoma of the hen, which thus far has been propagated into its fourth tumor generation. This was accomplished by the use of fowls of pure blood from the small, intimately related stock in which the growth occurred. Market-bought fowls of similar variety have shown themselves insusceptible, as have fowls of mixed breed, pigeons and guinea-pigs. The percentage of successful transplantations has been small, but in the individuals developing a tumor its growth has been fairly rapid. Young chickens are more susceptible than adults. The reinoculation of negative fowls has never resulted in a growth. Throughout, the sarcoma has remained true to type. It is infiltrative and destructive. Metastasis has been observed once (to the heart). Experiments to determine whether the growth may be transmitted by cell-fragments have not yet been made. Repeated bacteriological examinations have yielded negative results. In its general behavior, so far as tested, this avian tumor closely resembles the typical mammalian neoplasms that are transplantable.

The problem of eradicating ovarian infection in the domestic fowl assumes still greater importance than heretofore, in the light of data recently acquired. Not only is it of great significance to eliminate the permanent carriers of Bacterium pullorum from all flocks of fowls from the standpoint of successful poultry breeding, but also because they constitute a possible source of danger to man. Eggs which harbor Bacterium pullorum in the yolk in large numbers may produce abnormal conditions, when fed, not only in young chicks, but in adult fowls, young rabbits, guinea pigs, and kittens. The toxicity for young rabbits is most pronounced, the infection usually resulting in the death of the animals. In kittens the most prominent symptoms are those of severe food-poisoning with members of the paratyphoid group of bacteria. The possibility of infected eggs causing serious disturbances in young children and in the sick and convalescent of all ages must therefore receive serious consideration. Ovarian infection of fowls is very common throughout this country. Hence, a large proportion of the marketed eggs are infected with Bacterium pullorum. When such eggs are allowed to remain in nests under broody hens, or in warm storage places, for comparatively few hours...

It is possible by means of curves to depict graphically the behavior of the various antibodies under various conditions. Logarithmic curves based on the data presented in the tables are submitted in Text-fig. 1. In general it is evident that antibody destruction goes on gradually as the temperature is increased. Thus 65°C. for 20 minutes diminishes the activity of all the antibodies with the exception of red cell agglutinin, and in this case although the final titer was the same evidently some of the antibody was inactivated, since the reaction was weaker in the higher dilutions. It can, then, be said that 65°C. for 20 minutes appreciably affects the activity of all the antibodies tested. When the temperature is increased to 70°C. more marked differences are apparent. Here both types of the bacterial agglutinin and the precipitin are fairly stable when compared with hemolysin and red cell agglutinin. In both instances there is a sharp decline in the activity of the antibody. 75°C., however, is even a more critical temperature since at this point the somatic bacterial agglutinin and the precipitin are completely inactivated. The hemolysin and hemagglutinin behave alike. The flagellar agglutinin is the most resistant of the group to this temperature. When the temperature is increased to 80°C. the red cell agglutinin is completely inactivated...

Tuberculin from the human and from the bovine type of tubercle bacilli inhibits the growth of cells from explants of bone marrow, spleen and testes of tuberculous guinea pigs, and is toxic for these cells, but has no effect on explants of the same tissues from non-tuberculous animals. "Tuberculin" from other acid-fast bacteria has no inhibitory or toxic action on explants of tissues from either tuberculous or non-tuberculous guinea pigs. Tuberculins from the avian, bovine and human types of tubercle bacillus as well as "tuberculin" prepared from the Duval and from the Kedrowsky strains of M. leprae inhibit the growth of the cells of explants of the spleen and bone marrow of tuberculous fowls and are toxic for these cells, but have no effect on the explants from tissues of non-tuberculous chickens. "Tuberculins" from other acid-fast bacteria have no effect on the growth of explants of tissues from tuberculous or from non-tuberculous fowls. Tissue culture methods indicate that the sensitivity of tuberculous tissues to tuberculin is inherent in the cell, and that it cannot be passively transferred.

1. Of three species of mammals tested by peripheral inoculation (guinea pig, cat, and horse) none showed viremia under conditions which suggested that any of these species would serve as a frequent source of mosquito infection. 2. Of the birds tested (chicken, duck, and dove) all developed viremia and might readily serve as natural sources of mosquito infection. Chickens were shown to be very highly susceptible to infection by minute amounts of virus inoculated subcutaneously. 3. Virus may appear in the blood of chickens within 16 hours after inoculation and it has persisted till at least the 120th hour. No fowl showed any sign of illness as a result of the infection.

1. The causative agent of infectious laryngotracheitis of chickens was found to be present in bacteriologically sterile tracheal exudate, spleens, and livers of diseased fowls. 2. The causative agent was present regularly in the tracheal exudate, in the spleens of about 60 per cent, and in the livers of about 30 per cent of chickens with active laryngotracheitis infection. 3. Suspensions of the spleen and liver were less effective in inducing the disease than those made from the tracheal exudate. This finding, together with the absence of pathological changes in the spleens and livers would seem to indicate that they are not actively involved but that the causative agent is carried to them by way of the blood. 4. The disease could, in our experience, be produced only in chickens Domesticated ducks and several wild and free-flying species of birds, including sparrows, crows, starlings, doves, and pigeons were found to be refractory, and so too were rabbits, guinea pigs, white rats, and one pig that was tested.

Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Pós-graduação em Cirurgia Veterinária - FCAV; Objetivou-se, com este estudo, determinar se o butorfanol modifica a concentração anestésica mínima do sevofluorano (CAnMSEV) em função do tempo e avaliar os efeitos cardiorrespiratórios e eletrolíticos causados por essa associação em galinhas d'angola. Dez galinhas d'angola foram anestesiadas com sevofluorano e mantidas sob ventilação mecânica para determinação da CAnMSEV individual pelo modelo bracketing. A porcentagem de redução da CAnMSEV após a administração intravenosa de 2 ou 4,0 mg/kg de butorfanol em função do tempo foi estimada por regressão logística pelo método up-and-down. Em etapa subsequente, foram avaliados os efeitos cardiorrespiratórios do sevofluorano (1,0 CAnM) e de uma dose equipotente do sevofluorano (0,8 CAnM) associado ao butorfanol (4,0 mg/kg). A CAnMSEV média foi de 2,86 ± 0,09V%. Após 15 minutos da administração de 2,0 mg/kg de butorfanol, a redução da CAnMSEV foi de 8,52 ± 3,11V%. Após 15 e 30 minutos da administração de 4,0 mg/kg de butorfanol, a redução da CAnMSEV foi de 20...

Devido à escassez de estudos sobre muda forçada em aves alternativas de produção, este experimento teve o objetivo de realizar a muda forçada em galinhas D'Angola avaliando as perdas de peso corpóreo (PPC) que promovessem os melhores índices produtivos pós-muda. Com este propósito foram utilizadas 110 galinhas D'angola alojadas individualmente em gaiolas de poedeiras comerciais e, posteriormente, submetidas à muda forçada com 20000 ppm de óxido de zinco na ração. Estas passaram 21 dias recebendo ração e água ad libitum. Para análise da PPC relacionada à produtividade pós-muda foram utilizados 60 aves organizadas nos seguintes grupos: 24% (n=18); 26% (n=18); 28% (n=12) e acima de 30% (n=12). As outras 50 aves foram sacrificadas para o estudo do aparelho reprodutor, onde se verificou o tamanho e peso do oviduto e peso do ovário com PPC de 0% e sua regressão à medida que atingiam os níveis de PPC: 24%; 26%; 28% e acima de 30%. A média de retorno produtivo foi 60%, sendo o grupo com PPC de 24% com o melhor índice (100%), no entanto, este apresentou índice de produção insatisfatório juntamente com o grupo de PPC acima de 30%. A muda forçada em Galinhas D'Angola foi viável com índices de PPC em torno de 26% a 28% e inviáveis com níveis abaixo de 24% e acima de 30%. Em relação à regressão do aparelho reprodutor...

Este trabalho descreve algumas propriedades de um reovírus que foi isolado de pâncreas e intestino de galinhasd’angolaque padeciam de uma enterite transmissível. Coronavírus foi isolado do rim das mesmas aves. O reovírusde galinhas-d’angola é patogênico para embriões de galinha-d’angola, de pata e de galinha mas não reproduziu osachados de campo, quando inoculado em angolinhas, e nem foi patogênico para pintos e patinhos inoculados experimentalmente.; This paper describes some properties of a reovirus isolated from the pancreas and intestines of guinea fowls suffering from a transmissible enteritis. Coronavirus was also recovered from kidneys of the same birds. The guinea fowl reovirus is pathogenic for guinea fowl, duck and chicken embryos, but it does not reproduce by itself the field findings when inoculated in day-old guinea poults, nor was it found to be pathogenic for chicks and ducklings on experimental infection..

Los autores hacen una revisión de la problemática referida a la fiebre Q, tanto desde el punto de vista clínico como epidemiológico. El primer caso nacional se comunicó en el año 1956, en un adulto, obrero de frigorífico. En 1966 se comunica el primer caso en un niño. A partir de esa fecha se realizan varias encuestas serológicas en humanos y en animales. En seres humanos los hallazgos varían entre 4.2% y 5.5% según el año estudiado. En animales se hallaron valores que oscilaron entre 0.9% (animal para abasto) y 30% (animal tipo industria) para bovinos. En ovinos, en el único estudio se halló un 10.3% de positivos. En equinos los valores de positividad variaron de 5.5% a 21.7%. En suinos se refiere un porcentaje de positividad del 21.2% en la primera encuesta, sendo en la más reciente del 0.0%. En aves y cobayos no se evidenciaron sueros positivos. Entre 1975 y 1985 los autores estudiaron 14 brotes en seres humanos en esta-blecimentos de procesamiento de carne, con un total de 1358 casos estudiados, habiéndose confirmado el 60% de ellos. Pasan revista a la sintomatologia común, así como el tipo de tarea de los pacientes. Para los estudios serológicos, como los diagnósticos de los casos clínicos, los autores utilizaron la fijación del complemento...
