Identification and classification of Cronobacter spp. isolated from powdered food in Korea.
Cronobacter is a major food-borne pathogen in powdered infant formula and can lead to serious developmental aftereffect and death to infants. The contamination of Cronobacter may be a high risk for the powdered foods. To isolate and identify Korean Cronobacter from the powdered foods such as powdere...
A case of severe pancreatitis complicated by Raoultella planticola infection.
A 45-year-old-male presented with severe pancreatitis. Two bacterial isolates obtained from peritoneal fluid and abdominal purulent secretion were identified to the species level by 15 biochemical tests and four supplementary tests as Raoultella planticola. Identification was confirmed by rpoB gene...
The effect of caffeic acid phenethyl ester on bacterial translocation and intestinal damage in cholestatic rats.
We investigated the effect of caffeic acid phenethyl ester in rat ileum injury induced by chronic biliary obstruction. Swiss albino rats were divided into three groups: Group 1, sham (n = 7); Group 2, common bile duct ligation (n = 7); and Group 3, common bile duct ligation plus caffeic acid pheneth...
Luminal bacterial antigen-specific CD4+ T-cell responses in HLA-B27 transgenic rats with chronic colitis are mediated by both major histocom...
We investigated the role of antigen-presenting molecules involved in generating immune responses by CD4+ mesenteric lymph node (MLN) cells from colitic HLA-B27 TG rats to commensal enteric micro-organisms. All TG MLN cells expressed HLA-B27. A higher level of MHC class II was expressed on cells from...
Predominant microflora of downgraded Danish bulk tank milk.
The microflora of downgraded Danish bulk tank milk was examined to identify the main causes of increased microbial counts. Seventy-five representative samples with a microbial count exceeding 3.0 x 10(4) cfu/mL were selected for a more detailed microbial examination. A total of 1237 isolates from th...
Identification of inadequately cleaned equipment used in a sheep carcass-breaking process.
Aeromonads deposited on pork during a carcass-breaking process were recovered on hydrophobic grid membrane filters placed on ampicillin-dextrin-ethanol agar. Isolates from 85 honey-yellow colonies from filters on that medium were Aeromonas hydrophila (95%) or Vibrio sp. (5%). Presump...
Segmented filamentous bacteria are potent stimuli of a physiologically normal state of the murine gut mucosal immune system.
We studied the effect of SFB on the mucosal immune system by monoassociating formerly germfree C3H/HeN mice with SFB. At various time points during 190 days of colonization, fragment cultures of small intestine and Peyer's patches (PP) were analyzed for total immunoglobulin A (IgA) and SFB-specific...
Use of an isogenic Escherichia coli panel to design tests for discrimination of beta-lactamase functional groups of Enterobacteriaceae.
These results indicate the utility of an isogenic panel for identification of candidate drugs among many for further testing with clinical isolates of the family Enterobacteriaceae to determine the best agents for detection of specific beta-lactamases in this family....
The effect of probiotic strains on the microbiota of the Simulator of the Human Intestinal Microbial Ecosystem (SHIME).
The aim of the present work was to study five potential probiotic strains (Lactobacillus plantarum, two strains of L. paracasei subsp. paracasei, L. rhamnosus and Bifidobacterium sp.) comparatively in the Simulator of the Human Intestinal Microbial Ecosystem (SHIME) in vitro model, and to evaluate t...
Identification of Enterobacteriaceae bacteria by direct matrix-assisted laser desorptiom/ionization mass spectrometric analysis of whole cel...
Several members of Enterobacteriaceas were analyzed by matrix-assisted laser desorption ionization (MALDI) time-of-flight mass spectrometry (TOFMS). Characteristic mass spectral peaks and patterns were observed in the mass range of 2 to 20 kDa. The mass peaks reported to be reproducibly observed by...
