avian spirochaetosis: enhanced recognition of mild strains of borrelia anserina with bursectomized- and dexamethasone-treated chickens. 1979528695
[effectiveness of sodium arsamilate and its effect on the immunity of hens experimentally infected with borrelia anserina].the toxicity of sodium arsanilate for chickens was determined following a six-day oral application. doses higher than 0.15/kg body weight led to symptoms of intoxication and death, especially when the intake of water was restricted. no spirochetemia, clinical signs of spirochetosis, and death cases were noted in birds infected subcutaneously with a lethal dose of borrelia anserina simultaneously treated (orally) in the course of three days with sodium arsanilate either in solution or in tablets ...19761030868
borrelia anserina in chickens previously exposed to borrelia theileri.exposure of 10-week-old white leghorn chickens to sheep blood containing borrelia theileri neither resulted in infection nor conferred protection against b. anserina.19751120034
sequential changes in tissue d-fructose-1,6-diphosphate aldolase activity in chickens experimentally infected with borrelia anserina.following experimental borrelia anserina infection of chickens, aldolase activity increased in the proventriculus, heart and bone marrow but declined in the kidney and cervical spinal cord.19892631380

enteritis and green diarrhoea in experimental avian spirochaetosis.chickens infected with a virulent strain of borrelia anserina showed acute enteritis, haemosiderosis in intestinal villi and green diarrhoea. although spirochaetes in the intestine had begun to disintegrate 96 hours after infection, enteritis and green diarrhoea continued. it is suggested that the greenish discoloration may be a consequence of enteritis and haemosiderosis.19846522838
observations on the pathology of experimental avian experimental infection of chickens with a virulent strain of borrelia anserina, peak spirochaetaemia was recorded from 72 to 96 hours. progressive enlargement of the spleen with mottling was the predominant gross finding. spleen, liver and small intestine showed extensive erythrophagocytosis, which continued even after the disappearance of spirochaetes from blood and tissues. while haemosiderosis was mild in the lungs, it was absent from the heart, kidney and brain. spirochaetes were demonstr ...19836635339
[clinical and pharmacological studies of technical tylosin phosphate from pharmachem in poultry diseases].investigations on the healing anbd prophylactic effectiveness of the technical tylosine phosphate "pharmachim" with 50 iu/mg activity (pharmazin t-50) in some bird diseases were carried out. it was established that a dose of 20 g/kg fodder pharmazin t-50 applied 2 days pre- and 3 days post chicken mycoplasma gallisepticum infection protects the chickens completely from respiratory mycoplasmosis. in order to attain a sure healing and prophylactic effect in hen spirohetosis control 10 g/kg fodder ...19806998102
[blood concentrations and anti-borrelia anserina activity of erythromycin salts in birds].tested was comparatively the antispirochaetal activity of erythromycin asparaginate (ea), thiocyanate (et), and lactate (el) in a total of 314 chickens, pullets and cockerels artificially infected with borrelia anserina (strains surnevo and pamoukchii). the antibiotics were applied via the crop, with the drinking water, and subcutaneously. the general status of the birds mortality rate, spirocheataemia, and the blood level of antibiotics were followed up along with the effect of ea and et on the ...19827112926
augmentation of haemo-tissue vaccine doses out-turn through blood transfusion in borrelia anserina infected chickens. 19827136369
a morphological characterization of borrelia anserina.the morphology and ultrastructure of two strains of borrelia anserina were investigated by electron microscopy of negatively stained and ultrathin sectioned cells. one was a cultivable strain originally isolated in the usa and the other was originally isolated in nigeria and maintained in chickens. the cells were regularly helical, 9-21 microns long and 0.22-0.26 microns wide with a helix wavelength of about 1.7 microns. the cells were surrounded by a surface layer and appeared to divide by bina ...19957894723

use of fluorescein-labeled antibody to study borrelia anserina infection (avian spirochetosis) in the chicken. 196414227179
changes in the biochemical composition of blood in chickens infected with borrelia anserina.three-month-old chickens were inoculated intramuscularly with blood infected with borrelia anserina. the serum levels of the enzymes alkaline and acid phosphatases (alp and acp), glutamate-oxaloacetate transaminase (got), proteins, lipids, uric acid, blood sugar and inorganic phosphate were measure. there was a decrease of alp and increase of got levels in the infected group. the level of acp was unchanged. the spirochaetosis was also accompanied by an increase of total protein, globulin and uri ...197718770344
the use of the indirect fluorescent antibody technique in avian spirochaetosis.the indirect fluorescent antibody technique was used for the detection of antibodies to borrelia anserina in chicken serum. sera from immunised and convalescent chickens, following experimental infection, gave specific fluorescence, whereas no such reaction could be observed with sera of healthy chickens with no history of the disease. this technique was also used in preliminary tests of two isolates with respect to strain differences.197818770395
avian spirochetosis in chickens following experimental transmission of borrelia anserina by argas (persicargas) miniatus.this study reports the experimental transmission of borrelia anserina to domestic chickens by infected argas (persicargas) miniatus. clinical alterations as well as prepatent and patent periods were evaluated. twenty-seven 67-day-old birds were divided into three groups in a randomized experimental design. the first group was exposed to ticks infected with b. anserina, the second group was exposed to noninfected ticks, and the third group was not exposed to ticks. blood smears from each bird of ...200919630219
