| effects 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 21 d of age) and challenged with 5 x 10(8) virulent salmonella pullorum (7 d of age), and in vitro exp ... | 2009 | 19903952 |
| identification of salmonella pullorum genomic sequences using suppression subtractive hybridization. | pullorum disease affecting poultry is caused by salmonella enterica serovar pullorum and results in severe economic loss every year, especially in countries with a developing poultry industry. the pathogenesis of s. pullorum is not yet well defined, as the specific virulence factors still need to be identified. thus, to isolate specific dna fragments belonging to s. pullorum, this study used suppression subtractive hybridization. as such, the genome of the s. pullorum c79-13 strain was subtracte ... | 2009 | 19809245 |
| prevalence of salmonella in vegetables from mexico. | the present study is an overview of the role of vegetables as a transmission vehicle of salmonella in mexico. one hundred samples of each of 17 different vegetables were analyzed during a period of 18 months. salmonella was isolated from 98 samples. salmonella enterica serovar typhimurium was isolated from the highest percentage of samples with typeable salmonella isolates (23.9%), followed by s. enterica subsp. arizonae and salmonella choleraesuis each from 16.9%, salmonella gallinarum from 11. ... | 2009 | 19610340 |
| search for salmonella spp. in ostrich productive chain of brazilian southeast region. | we analyzed ostriches from an equipped farm located in the brazilian southeast region for the presence of salmonella spp. this bacterium was investigated in 80 samples of ostrich droppings, 90 eggs, 30 samples of feed and 30 samples of droppings from rodents. additionally, at slaughter-house this bacterium was investigated in droppings, caecal content, spleen, liver and carcasses from 90 slaughtered ostriches from the studied farm. also, blood serum of those animals were harvested and submitted ... | 2009 | 19390983 |

| evaluation of the efficacy of apramycin against salmonella pullorum infection in chickens. | the efficacy of apramycin given orally at dose levels of 225, 150 and 75 mg/litre for five days to chicks experimentally infected with salmonella pullorum has been evaluated. the results show that this drug, when utilised at the dose level of 225 mg/litre for five days, totally suppresses mortality and significantly reduces salmonella excretion in comparison with non-treated chicks. | 1987 | 18766617 |
| stronger in vitro phagocytosis by monocytes-macrophages is indicative of greater pathogen clearance and antibody levels in vivo. | monocytes-macrophages are crucial players in specific and nonspecific immune responses to protect organisms from invasion of bacteria or viruses. in this study, monocytes in circulation from 2 lines of silky and starbro chickens with different disease resistance were separated and cultured in vitro. after identification with acridine orange (ao), giemsa staining, and cd14 immunostaining, monocytes-macrophages were used for adherence and phagocytosis test. the overall percentages of adherence of ... | 2008 | 18753439 |
| salmonella control--past, present and future. | the perception of salmonella infection as a problem to the poultry industry has changed as the industry itself has changed. other factors include increasing awareness of health and food quality. acquisition of more information on the microbiology of salmonella and the epidemiology of infection in poultry and man, have not, with a few exceptions, enabled us to eliminate salmonella from poultry and from the food chain. control of the poultry pathogens s. pullorum and s. gallinarum, the major patho ... | 1993 | 18671051 |
| examination by elisa of sera obtained from chicken breeder and layer flocks showing evidence of fowl typhoid or pullorum disease. | an indirect elisa using soluble whole cell antigen was used to screen serum samples obtained from breeder and layer flocks some of which had shown clinical or bacteriological evidence of infection with salmonella gallinarum or s. pullorum. there was good correlation between salmonella infection and the presence of serum samples showing high optical density (od) values. sera from seven flocks showing high values were retested using group d (0-1, 9, 12) lipopolysaccharide (lps) and g,m-h flagella ... | 1995 | 18645798 |

| an allele-specific pcr assay for the rapid and serotype-specific detection of salmonella pullorum. | salmonella serovar pullorum is a causative agent of pullorum disease (pd) in poultry and is responsible for severe economic losses to the poultry industry in many parts of the world. a definitive detection of pullorum requires culture followed by serotyping and biochemical identification, a process that is tedious and takes several weeks to accomplish. we have developed a rapid allele-specific polymerase chain reaction (pcr) method based on the nucleotide polymorphism in rfbs gene sequence for t ... | 2005 | 16404999 |
| [the antibiotic sensitivity patterns of salmonella pullorum and salmonella gallinarum in in vitro studies]. | the antibiotic sensitivity patterns of 100 strains of s. pullorum and 24 strains of s. gallinarum against 19 antibiotics and 3 antibiotic mixtures were determined by the broth dilution method. the strains studied were isolated from enzootic outbreaks of pullorum disease and fowl typhoid. it was found that all the strains were sensitive to ampicillin, streptomycin, neomycin, kanamycin, oxytetracycline, chloromycetin, gentamycin, signamycin, polzomycin, and neotarchocin. besides, s. pullorum was s ... | 1975 | 16296026 |

| the genome of salmonella enterica serovar gallinarum: distinct insertions/deletions and rare rearrangements. | salmonella enterica serovar gallinarum is a fowl-adapted pathogen, causing typhoid fever in chickens. it has the same antigenic formula (1,9,12:--:--) as s. enterica serovar pullorum, which is also adapted to fowl but causes pullorum disease (diarrhea). the close relatedness but distinct pathogeneses make this pair of fowl pathogens good models for studies of bacterial genomic evolution and the way these organisms acquired pathogenicity. to locate and characterize the genomic differences between ... | 2005 | 15995186 |
| allele-specific pcr method based on rfbs sequence for distinguishing salmonella gallinarum from salmonella pullorum: serotype-specific rfbs sequence polymorphism. | cloning and sequence analysis of rfbs gene identified two polymorphic nucleotides, one at position 598 (salmonella gallinarum-specific) and other at position 237 (salmonella pullorum-specific). based on s. gallinarum-specific nucleotide found at position 598, an allele-specific pcr method was developed for serotype-specific detection of s. gallinarum. this pcr method was able to discriminate pure cultures of s. gallinarum from s. pullorum and other salmonella serotypes from serogroup d in less t ... | 2005 | 15590091 |
