BACKGROUND Salmonella spp. is the major bacterial pathogen in poultry and is responsible for significant economic losses of the poultry industry in many parts of the world. Among Salmonella spp., Salmonella gallinarum and Salmonella. pullorum are the most common causative agents of chicken salmonellosis resulting in high mortality and morbidity. OBJECTIVES The aim of this study was to identif...

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.

Blood parasites are often found in the blood smears of domestic and wild-caught birds [12,14]. Of these, a member of the family Anaplasmataceae, Aegyptianella (CARPANO, 1929) genus has been reported from domestic fowl, ducks, geese, turkeys, pigeons, quails, ostrichs and psittacine birds [9, 13,14]. The only named species is Aegyptianella pullorum, known in the past as Babesia pullorum or Balfo...

Salmonella enterica is responsible for major foodborne outbreaks worldwide. It can cause gastroenteritis characterized by diarrhea, vomiting, and fever. Salmonella infections raise public health concerns along with consequential economic impacts. In this report, we announce the first complete genome sequences of Salmonella enterica subsp. enterica serovar Choleraeuis (S. Choleraeuis) ATCC 10708...

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...

BACKGROUND Poultry represent an important source of foodborne enteropathogens, in particular thermophilic Campylobacter species. Many of these organisms colonize the intestinal tract of broiler chickens as harmless commensals, and therefore, often remain undetected prior to slaughter. The exact reasons for the lack of clinical disease are unknown, but analysis of the gastrointestinal microbiota...

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...
