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...

A total of 110 broilers from 11 flocks were tested for Helicobacter pullorum by polymerase chain reaction; positive samples were reexamined with a conventional isolation method. H. pullorum isolates were examined by amplified fragment length polymorphism (AFLP) fingerprinting for interstrain genetic diversity and relatedness. Sixteen isolates from cecal samples from 2 different flocks were obta...

Pullorum disease causing acute septicemia and mortality in adult brown chickens was diagnosed in a small-farm chicken flock in Iowa. Also, Salmonella Pullorum was isolated from the intestine of one of four rats trapped on this index farm. Tracing movements of spent hens from the index farm resulted in identification of a second infected flock on a contact farm. Poultry on the contact farm were ...

Meat and meat products are important sources of human intestinal infections. We report the isolation of Helicobacter pullorum strains from chicken meat. Bacteria were isolated from 4 of the 17 analyzed fresh chicken meat samples, using a membrane filter method. MIC determination revealed that the four strains showed acquired resistance to ciprofloxacin; one was also resistant to erythromycin, a...

Helicobacter pullorum represents a potential food-borne pathogen, and avian species appear to be a relevant reservoir of this organism. In this study, the prevalence of H. pullorum was investigated at 30 conventional farms where 169 ceca from 34 flocks were tested, at eight organic farms where 39 ceca from eight flocks were tested, and at seven free-range farms where 40 ceca from eight flocks w...

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...

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...

the presence of helicobacter pullorum in intestinal tract of broiler chickens may be a potential risk for human health. in this study, a total of 100 caecal samples of broilers carcasses from 20 flocks at a poultry abattoir in mashhad suburb were tested for the presence of h. pullorum using modified conventional culture method by combination of culturing on brucella sheep blood agar and a filte...
