| the influence of protein source and basal dietary component on survival in acute experimental fowl typhoid in the chick (gallus domesticus). | 1. the influence of diet on the survival of chicks inoculated orally at 15 d of age with salmonella gallinarum was determined, and in the first experiment the numbers of salmonellae were counted in blood 5 or 7 d after inoculation to assess their value in predicting survival. 2. significantly more chicks survived among those given beef powder as the protein supplement in a starch-based diet than among those where fish flour replaced beef powder. the number of salmonellae in blood was significant ... | 1977 | 588545 |
| [changes in the toxic, antigenic and immunogenic properties of the o-antigen of salmonella gallinarum-pullorum irradiated with gamma rays]. | studied was the effect of gamma-rays at rates of 1 to 20 mr on the toxic, antigenic, and immunogenic properties of the o-antigen extracted from salmonella gallinarum-pullorum by the method of boivin. it was found that the irradiation of aqueous solutions of the o-antigen lowered the toxic, antigenic, and immunogenic capacity with the increase in the dose of treatment. strongest detoxication of the endotoxin was produced through irradiation at the rate of 10 mr, and especially at 20 mr. the antig ... | 1977 | 595373 |
| increased survival from acute salmonella gallinarum infection in chicks given diets with high levels of some forms of iron. | amounts exceeding 100 ppm of extra dietary iron as the ferric salts of ethylenediaminetetra-acetic acid (fee) or nitrilotri-acetic acid (fen) produced highly significant increases in survival among chicks infected with 10(6.4) living salmonella gallinarum strain 9. additional dietary iron (400 ppm) as the sulphate or chloride salts (or as ferric fructose) lacked activity comparable with fee or fen except when 0.2 per cent of nae was also present in the diet. fee iron (600 ppm) also diminished th ... | 1977 | 605293 |
| a fowl typhoid outbreak in a chicken breeder flock. | fowl typhoid was diagnosed in a 1-year-old light-breed brown-egg-laying chicken breeder flock and in a 16-week-old progeny pullet flock on the same farm. salmonella gallinarum was cultured from chickens in both flocks. signs and lesions were typical. the disease was confined to the one farm. the source was suspected to have been a grossly contaminated well. | 1977 | 606229 |
| [diagnostic value of serological methods and of the allergy method in studying pullorum disease-fowl typhoid in poultry]. | it was established that the positive allergy reaction was best expressed at the forty-eighth hour following the introduction of the allergen. the diagnostic value of the allergy reaction was not shown to surpass that of the serum agglutination reaction. it proved to be close to the value of the other serologic methods of examination (the whole-serum and whole-blood agglutination tests). the allergy method of investigation could be used as a tentative method, resp., reaction test for the detectio ... | 1977 | 607558 |
| experimental induction of an immunohaemolytic anaemia in the chicken with salmonella gallinarum endotoxin. | the possibility that the extreme refractoriness of the chicken to injected endotoxin would permit the buildup of sufficient free endotoxin in the circulation to immunologically modify the erythrocytes in vivo and thereby cause them to be eliminated from the circulation was investigated. it was shown that a moderately severe immunohaemolytic anaemia accompanied by a mild spenomegaly could be induced in chickens by single (large) or multiple injections of salmonella gallinarum endotoxin (sge). var ... | 1978 | 647450 |

| [dynamics of agglutination in birds artificially infected with salmonella gallinarum-pullorum and salmonella typhimurium and treated with sulfaguanidine and furazolidone]. | canadian leghorn chickens were used to study the effect of sulfaguanidine and furazolidon on the dynamics of blood agglutinin formation. the birds were artificially infected with salmonella gallinarum-pullorum and salmonella typhimurium. at various intervals following infection they were treated with sulfaguanidine 1% tablets and 0.04% furazolidon. the level of agglutinins was determined by the methods of huddleson (whole blood agglutination reaction), the fast serum agglutination, the method af ... | 1976 | 797104 |
| experimental fowl typhoid in chicks impaired immunologically by treatment with cyclophosphamide. | male chicks were injected intramuscularly with 6 mg of cyclophosphamide daily for three consecutive days, the initial dose being given on the day of hatching. this treatment impaired bursal development and lymphopoiesis and no circulating antibodies appeared after such chicks were injected with salmonella gallinarum antigens at 19 and again at 26 days of age. in impaired chicks which were infected orally when 15 days old with s gallinarum the level of mortality was essentially the same as that i ... | 1977 | 841202 |
| enhancement of survival in acute experimental fowl typhoid in chicks by the administration of iron dextran. | chicks aged 15 days were infected orally with 10(6-4) living salmonella gallinarum. iron from iron dextran or ferric ammonium citrate (dfe and cfe respectively), in doses of 2-0 or 0-4 mg/kg given intramuscularly at the time of infection, had no effect on subsequent mortality compared with infected controls. increasing the amount of cfe to the maximum (20 mg/kg) that was non-toxic intramuscularly was also ineffective but when the dose of dfe was increased to 20 or 50 mg/kg the survival rate rose ... | 1977 | 870957 |
| altered absorption and regulation of iron in chicks with acute salmonella gallinarum infection. | chicks aged 15 days were infected orally with salmonella gallinarum. during the six-day period immediately following infection the absorption of 59fe from the gut fell progressively to be eventually about half that in noninfected chicks. this reduced uptake was accompanied by a shift in the distribution of the 59fe absorbed, more occurring in the spleen and less in the liver and blood. during the eight-day period that immediately followed infection in another experiment, serum iron concentration ... | 1977 | 877434 |
| [age-related dynamics of agglutinin formation in poultry experimentally infected with salmonella gallinarum-pullorum]. | agglutinin production in birds experimentally infected with salmonella gallinarum-pullorum directly correlates with age. the older the birds, the earlier setting on of agglutinogenesis, and the better the immune response. along with this agglutinins persist longer in the blood serum. it is suggester to carry out the first serologic examination in infected flocks of the leghorn breed when the birds are aged 50-55 days. this term may be essential only in cases where the birds have been infected at ... | 1977 | 919340 |
| [antibody dynamics in growing birds experimentally infected or naturally sick with white diarrhea]. | serologic studies were carried out with growing birds, aged 37-70 days, experimentally and spontaneously infected with salmonella gallinarum and salmonella pullorum, respectively. more positively reacting birds were found by means of the whole-blood agglutination reaction with typhoid-pullorum test than in the study of the same birds when aged 6-7 months. the investigation of birds when young is also advantageous in that there are no losses of eggs, it is more readily carried out, and the infect ... | 1977 | 929972 |
