Salmonella is the chief causative agent to cause mortality and reduced production in poultry industry. Fowl typhoid and pullorum disease are the two main bacterial diseases which is caused by Salmonella gallinarum and Salmonella pullorum respectively and having zoonotic importance. Enteritis, bacteremia, reduced egg production, diarrhea, inappetance are the main signs and symptoms caused by the...

Mycoplasmas were isolated from chickens with respiratory problems during field investigations of a concentrated respiratory disease outbreak in western Cuba, 1997. A high percentage of mycoplasma cultures from tracheas and air-sac lesions yielded pure cultures of Mycoplasma pullorum. The aim of the present work was to investigate the heterogeneity among M. pullorum isolates from Cuba and strain...

Salmonellosis is a very important disease of avian species because of its huge economic impact, worldwide distribution and difficulty posed in its control. Fowl typhoid and pullorum disease, is caused by Salmonella enterica subsp enterica serovar Gallinarum biovar Gallinarum and Pullorum. The purpose of this study was to investigate the biochemical characteristics and antimicrobial susceptibili...

When 11-day mice are fed with homologous or heterologous antibodies or with heterologous y-globulin, the maximum concentration of these proteins in their sera is reached 2 h later, irrespective of the amount or specificity of the proteins administered, or of the final con­ centration achieved. The relation between y (= relative titre of antibody, or concentration of heterologous y-globulin, att...

Many regulatory and diagnostic programs for the detection of Salmonella enterica serotype Enteritidis infection in commercial poultry flocks have relied on rapid Pullorum agglutination tests to screen birds because of the shared antigens of S. enterica Enteritidis and S. enterica Pullorum and Gallinarum; however, the use of the enzyme-linked immunosorbent assay (ELISA) format affords better ana...

S. Pullorum (SP) and S. Gallinarum (SG) are very similar. They are the agents of pullorum disease and fowl typhoid, respectively, and the two diseases are responsible for economic losses in poultry production. Although SP and SG are difficult to be differentiated in routine laboratory procedures, the ability to metabolize ornithine is a biochemical test that may be used to achieve this aim. Whi...
