Chickens were experimentally infected with Salmonella thompson (serogroup C, paratyphoid) and Salmonella pullorum (serogroup D). Five serological methods and one cultural method were used in detecting the infections. The microantiglobulin test was superior to all other methods for detection of paratyphoid (S. THOMPSON) infection and was followed in efficacy by the microagglutination test, rapid...

The article provides data on the isolation and identification of pathogen S. Pullorum from pathological material chickens. With further study tinctorial, cultural-morphological biological properties pathogen. susceptibility Salmonella pullorum to broad-spectrum antibacterial drugs such as cephalosporins carbopenems was studied determine drug choice for improving treatment prevention avian bacte...

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...

Most species of Salmonella grow rapidly and luxuriantly on ordinary agar media. In contrast, Salmonella pullorum and a few other species or types such as Salmonella abortus-ovis, Salmonella sendai, and Salmonella typhi-suis develop slowly and sparsely (Kauffmann, 1954). The reasons for the poor growth of these strains are not known. Also, their sparse growth makes isolation more difficult. In t...

Salmonellae are gastrointestinal pathogens of man and animals. However, strains that are host-specific avian pathogens are often avirulent in mammals, and those which are nonspecific are commensal in poultry. The objective of this study was to determine whether host specificity was exhibited by bacterial abilities to invade epithelial cells or resist leukocyte killing. In this study, leukocytes...

Specific pathogen-free CD-1 and C57Bl mice were infected in a hind footpad with 5 x 10(4) viable Salmonella enteritidis cells or 10(7) viable S. pullorum cells. The resulting bacterial growth within the footpad, the draining lymph nodes, and the liver and spleen was followed for 14 days. Mice vaccinated with live S. enteritidis rapidly developed an effective antibacterial resistance to both int...

Recombinant FimH adhesins of type 1 fimbriae from Salmonella enterica serovar Gallinarum biovars Gallinarum and Pullorum, in contrast to those of Salmonella enterica serovar Typhimurium, did not bind to high-mannose oligosaccharides or to human colon carcinoma HT-29 cells. However, mutated FimH proteins from biovar Gallinarum and biovar Pullorum, in which the isoleucine at position 78 was repla...

Salmonella enterica subsp. enterica serovar Gallinarum biovar Pullorum is a bird-restricted pathogen which causes pullorum disease. The strain FCAV198 was isolated from a pool of chicken ovaries in Brazil, and its genome may be helpful for studies involving molecular mechanisms related to pathogenesis and other related applications.

Poultry are commonly infected with a wide variety of salmonella serovars and infection is generally subclinical (Wray et al., 1996). Poultry farming is often hampered by reduction in productivity due to infections with large number of bacteria, salmonellosis being the most important causing great economic losses due to mortality and reduction in egg production (Khan et al., 1998). Under the new...

Salmonella enterica Enteritidis (S. Enteritidis) and Salmonella enterica Pullorum (S. pullorum) are regarded as a threat to poultry production. This study's aim is to characterize the expression profiles in response to three different challenges and to identify infection-related genes in the chicken spleen and caecum. Groups of the Chinese chicken breed Langshan were challenged with either S. E...
