| incidence of salmonella in fish and seafood. | field laboratories of the u.s. food and drug administration collected and tested 11,312 import and 768 domestic seafood samples over a 9-year period (1990 to 1998) for the presence of salmonella. the overall incidence of salmonella was 7.2% for import and 1.3% for domestic seafood. nearly 10% of import and 2.8% of domestic raw seafood were positive for salmonella. the overall incidence of salmonella in ready-to-eat seafood and shellfish eaten raw was 0.47% for domestic--one shucked oyster and on ... | 2000 | 10826714 |
| irradiation inactivation of four salmonella serotypes in orange juices with various turbiditiest. | reconstituted orange juice inoculated with salmonella anatum, salmonella infantis, salmonella newport, or salmonella stanley was treated with gamma radiation at 2 degrees c. to determine the relationship between juice antioxidant power and dgamma (dose required to achieve 90% mortality), juice solids were removed prior to inoculation by centrifugation and/or filtration to create juice preparations of varying turbidity. in unadulterated orange juice, salmonella anatum (dgamma = 0.71 kgy) was sign ... | 2001 | 11347989 |
| two processing methods for the isolation of salmonella from naturally contaminated alfalfa seeds. | two processing methods were examined for the recovery of salmonella from naturally contaminated alfalfa seed. seed samples, from each of three investigations, were processed by sprouting and shredding before preenrichment and culture. in lot a, salmonella serotype newport was isolated from 3 of 30 sample units with the sprouting method and 2 of 30 with the shredding method. in lot b, three serotypes in various combinations were isolated from 10 of 30 sample units with the sprouting method and 9 ... | 2001 | 11510668 |
| wrinkled alfalfa seeds harbor more aerobic bacteria and are more difficult to sanitize than smooth seeds. | at least 14 separate outbreaks of food poisoning attributed to either salmonella enterica or escherichia coli o157:h7 have been traced to sprouts in the past decade. seeds contaminated with human pathogens caused most of these outbreaks, thus many sprout growers are now treating alfalfa seeds with the sanitizing agent, calcium hypochlorite (ca[ocl]2), prior to sprouting. the efficacy of alfalfa seed sanitation varies between seed lots and between seeds within each lot. alfalfa seeds from differe ... | 2001 | 11563502 |
| the antibacterial action of microcin j25: evidence for disruption of cytoplasmic membrane energization in salmonella newport. | microcin j25 (mccj25) is a cyclic peptide of 21 unmodified amino acid residues produced by a fecal strain of escherichia coli. it has previously been shown that the antibiotic activity of this peptide is mainly directed to enterobacteriaceae, including several pathogenic e. coli, salmonella and shigella strains. in this paper we show that mccj25 acts on the cytoplasmic membrane of salmonella newport cells producing alteration of membrane permeability, and the subsequent gradient dissipation, tha ... | 2001 | 11731133 |

| outbreak of multidrug-resistant salmonella newport--united states, january-april 2002. | during january-april 2002, salmonella serotype newport was isolated from 47 persons in five states: new york (34 cases), michigan (five), pennsylvania (four), ohio (two), and connecticut (two). antimicrobial-susceptibility testing of three isolates by cdc revealed resistance to amoxicillin/clavulanate, ampicillin, cefoxitin, ceftiofur, cephalothin, chloramphenicol, streptomycin, sulfamethoxazole, and tetracycline. in addition, two of three isolates were resistant to kanamycin; two had decreased ... | 2002 | 12118534 |

| molecular characterization of cephalosporin-resistant salmonella enterica serotype newport isolates from animals in pennsylvania. | multidrug-resistant (mdr) strains of salmonella enterica serotype newport have been described for many years. however, the recognition of newport strains with resistance to cephalosporin antibiotics is more recent. plasmid-mediated cmy-2 ampc beta-lactamases have been identified in salmonella in the united states, and the bla(cmy-2) gene has been shown to be present in salmonella serotype newport. this organism is currently undergoing epidemic spread in both animals and humans in the united stat ... | 2002 | 12454172 |

| microbiological study of ready-to-eat salad vegetables from retail establishments uncovers a national outbreak of salmonellosis. | the increasing availability of bagged prepared salad vegetables reflects consumer demand for fresh, healthy, convenient, and additive-free foods that are safe and nutritious. during may and june 2001 a study of retail bagged prepared ready-to-eat salad vegetables was undertaken to determine the microbiological quality of these vegetables. examination of the salad vegetables revealed that the vast majority (3,826 of 3,852 samples; 99.3%) were of satisfactory or acceptable microbiological quality ... | 2003 | 12636292 |
| florfenicol resistance in salmonella enterica serovar newport mediated by a plasmid related to r55 from klebsiella pneumoniae. | florfenicol resistance has emerged over the past few years in multidrug-resistant salmonella enterica serovars typhimurium, agona and paratyphi b. the flor gene encoding florfenicol resistance is chromosomally located in these serovars within a genomic island of 43 kb called sgi1 (salmonella genomic island 1). in the present study, we characterized florfenicol resistance in a strain of s. enterica serovar newport isolated from a turkey in 1990 and that lacked sgi1. florfenicol resistance was med ... | 2003 | 12654754 |
| chemical modification of microcin j25 with diethylpyrocarbonate and carbodiimide: evidence for essential histidyl and carboxyl residues. | in this paper we compared the antibacterial activity of native microcin j25, a peptide antibiotic, with the activities of two analogues obtained by chemical modifications. in the first analogue, the negative charge of glutamic carboxyl group was specifically blocked with an l-glycine methyl ester and in the second the histidine imidazole ring was carbethoxylated. both analogues decreased notably its antibiotic activity against escherichia coli and salmonella newport, strains sensible to the nati ... | 2003 | 12659839 |
| automated ribotyping and pulsed-field gel electrophoresis for rapid identification of multidrug-resistant salmonella serotype newport. | in a series of 116 salmonella enterica newport isolates that included 64 multidrug-resistant (mdr) isolates, automated ribotyping and pulsed-field gel electrophoresis (pfge) discriminated mdr s. newport with a sensitivity of 100% and 98% and specificity of 76% and 89%, respectively. clustering of pfge patterns (but not ribotyping) linked human and bovine cases. automated ribotyping rapidly identified the mdr strain, and pfge detected associations that aided epidemiologic investigations. | 2003 | 12702235 |
