Pullorum disease of chickens is a bacterial infection caused by Salmonella enterica subspecies enterica serovar Gallinarum biovar Pullorum
In its acute form, Pullorum disease is almost exclusively a septicaemic disease of young chickens. However, the organism may also be associated with disease in turkey poults and may be carried subclinically or lead to reduced egg production and hatchability plus a range of atypical signs in older birds. Ovarian transmission is a major route by which the organism can spread. Game birds and ‘back...
متن کاملAlterations in the nitrogen excretion pattern of chicks infected with Salmonella pullorum.
Investigations in our laboratory have established that infection with SalmoneUa pulorum strain CDC 3522/51 results in a decrease in arginine, methionine, glycine and tryptophan in the blood and liver of 1to 3-day old White Leghorn cockerels (Ross et al., 1955a). Subsequent experiments revealed that the administration of arginine within 24 hr following infection produced a marked increase in sur...
متن کاملEffects of methyltestosterone on immunity against Salmonella Pullorum in dwarf chicks.
This study was conducted to determine effects of methyltestosterone on innate immunity and adaptive immunity against Salmonella Pullorum in dwarf chicks. In vivo experiment, comparisons of pathological sections, viable counts of bacteria, specific antibody levels, and subsets of T lymphocytes were set forth between chicks with or without 10(-7) M methyltestosterone treatment (2 d of age through...
متن کاملSynthesis of glutamic acid and alanine by Salmonella pullorum.
The literature reveals many references to transamination by bacteria. Two well substantiated works are those of Cutinelli (1945) and Lichstein and Cohen (1945). Goodlow, Mika, and Braun (1950) and Altenbern and Housewright (1951) have demonstrated synthesis of alanine by BruceUa abortus involving this method. Altenbern and Housewright also showed that their organism was capable of direct or red...
متن کاملThermolabile Sulfite Reductase from Salmonella pullorum'
The biochemical basis for sulfite accumulation by sulfate-using revertants of Salmonella pullorum was determined. All of the sulfate-using mutants isolated from wild-type S. pullorum accumulated sulfite when grown at 37 but not at 25 C. The specific activity of reduced nicotinamide adenine dinucleotide (NADPH)-dependent sulfite reductase (H2S-NADP oxidoreductase, EC 1.8.1.2) and of reduced meth...
