1. Ongoing multistate outbreak of Escherichia coli serotype O157:H7 infections associated with consumption of fresh spinach--United States, September 2006.
Match Strength: 11.896
On September 13, 2006, CDC officials were alerted by epidemiologists in Wisconsin and Oregon that fresh spinach was the suspected source of small clusters of Escherichia coli serotype O157:H7 infections in those states. On the same day, New Mexico epidemiologists contacted Wisconsin and Oregon epidemiologists about a cluster of E. coli O157:H7 infections in New Mexico associated with fresh spinach consumption. Wisconsin public health officials had first reported a cluster of E. coli O157:H7 infections to CDC on September 8. On September 12, CDC PulseNet had confirmed that the E. coli O157:H7 ...

2. Five-year surveillance of nosocomial infections in Ankara Training and Research Hospital.
Match Strength: 7.677
The objective of this study was to assess the rate of nosocomial infections (NIs), frequency of nosocomial pathogens and antimicrobial susceptibility changes in a 530-bed hospital over a five-year period. Hospital-wide laboratory-based NI surveillance was performed prospectively between 1999 and 2003. The Centers for Disease Control and Prevention's definitions were used for NIs and nosocomial surgical site infections, and NI rates were calculated by the number of NIs per number of hospitalized patients on an annual basis. NI rates ranged between 1.4% and 2.4%. Higher rates were observed in ... Read More »

3. Prebiotic galactooligosaccharides reduce adherence of enteropathogenic Escherichia coli to tissue culture cells.
Match Strength: 6.703
Prebiotic oligosaccharides are thought to provide beneficial effects in the gastrointestinal tract of humans and animals by stimulating growth of selected members of the intestinal microflora. Another means by which prebiotic oligosaccharides may confer health benefits is via their antiadhesive activity. Specifically, these oligosaccharides may directly inhibit infections by enteric pathogens due to their ability to act as structural mimics of the pathogen binding sites that coat the surface of gastrointestinal epithelial cells. In this study, the ability of commercial prebiotics to inhibit ... Read More »

4. Susceptibility testing of clinical isolates of pseudomonas aeruginosa to levofloxacin, moxifloxacin, and gatifloxacin as a guide to treating pseudomonas ocular infections.
Match Strength: 6.371
PURPOSE: Pseudomonas aeruginosa ocular infections most frequently originate from an environmental source; successful treatment with various ocular antibiotics is well established. However, emergence of resistant clones to available antibiotics poses a real threat to successful treatment. The purpose of this study was to evaluate the antibiotic susceptibilities of 100 random clinical isolates of P. aeruginosa to levofloxacin, moxifloxacin, and gatifloxacin, potential agents for the treatment of ocular infections caused by this microorganism. METHODS: One hundred consecutive strains of P. ... Read More »

5. Antibiotic resistance of urinary tract pathogens and evaluation of empirical treatment in Turkish children with urinary tract infections.
Match Strength: 5.593
The changing pattern of antimicrobial resistance in the causative microorganisms of urinary tract infection (UTI) in childhood is a growing problem. The aims of this study were to assess the resistance patterns of urinary isolates to commonly used antimicrobials and to evaluate the options for empirical treatment of UTI. A prospective cross-sectional analysis of bacteria isolated from children with UTI was performed between January 2003 and January 2004. Resistance to antibiotics was analysed in three age groups: Group I, < or =12 months; Group II, 13-60 months; and Group III, >60 months ... Read More »

6. In vitro activity of cefepime combined with sulbactam against clinical isolates of carbapenem-resistant Acinetobacter spp.
Match Strength: 5.580
The aim of this study was to assess the in vitro activity of cefepime combined with sulbactam against carbapenem-resistant clinical isolates of Acinetobacter spp. The checkerboard method was used to determine whether combinations act synergistically against these strains. Twenty-three Acinetobacter baumannii and one Acinetobacter junii found to be carbapenem resistant were included in the study. The susceptibility results for cefepime and sulbactam were interpreted according to the guidelines of the Clinical and Laboratory Standards Institute. Pseudomonas aeruginosa ATCC 27853 and Escherichia ... Read More »

7. Differential expression and antibacterial activity of WFDC10A in the monkey epididymis.
Match Strength: 5.570
The ability of the epididymis to perform its diverse functions stems from its regionalized gene and protein expression patterns. The differences in the gene expression patterns of the caput and cauda regions of the bonnet monkey epididymis were compared using the technique of differential display reverse transcriptase polymerase chain reaction. A transcript showing homology to human whey acidic protein 10 (hWFDC10A) was highly expressed in the monkey caput region. A peptide P2 was designed spanning a region of the monkey WFDC10A (mWFDC10A), which could inhibit the growth of gram-negative ... Read More »

8. Bacillus subtilis spores reduce susceptibility to Citrobacter rodentium-mediated enteropathy in a mouse model.
Match Strength: 5.436
The present work was aimed at investigating whether Bacillus subtilis spores, widely used in probiotic as well as pharmaceutical preparations for mild gastrointestinal disorders, can suppress enteric infections. To address this issue, we developed a mouse model of infection using the mouse enteropathogen Citrobacter rodentium, a member of a family of human and animal pathogens which includes the clinically significant enteropathogenic (EPEC) and enterohemorrhagic (EHEC) Escherichia coli strains. This group of pathogens causes transmissible colonic hyperplasia by using attaching and effacing (A ... Read More »

9. Impact of inactive empiric antimicrobial therapy on inpatient mortality and length of stay.
Match Strength: 4.786
The consequences of inactive empiric antimicrobial therapy are not well-described and may cause prolonged hospitalization or infection-related mortality. In vitro susceptibility results for 884 patients hospitalized at an academic medical center with gram-negative bloodstream infections (GNBI) from 2001 to 2003 were matched to antimicrobial orders within 24 h of culture. Clinical characteristics, organism, inpatient mortality, and length of stay after culture for patients with GNBI were compared between patients receiving active versus inactive empiric antimicrobial therapy. A total of 14.1% ... Read More »

10. Public health significance of antimicrobial-resistant gram-negative bacteria in raw bulk tank milk.
Match Strength: 4.752
The dairy farm environment and animals on the farm serve as important reservoirs of pathogenic and commensal bacteria that could potentially gain access to milk in the bulk tank via several pathways. Pathogenic gram-negative bacteria can gain access to bulk tank milk from infected mammary glands, contaminated udders and milking machines, and/or from the dairy farm environment. Contaminated raw milk when consumed by humans or fed to animals on the farm can result in gastroenteric infections in humans and animals and also provide an opportunity for organisms to colonize the farm environment. ...

11. Vitamin A supplementation reduces the monocyte chemoattractant protein-1 intestinal immune response of Mexican children.
Match Strength: 4.326
The impact of vitamin A supplementation on childhood diarrhea may be determined by the regulatory effect supplementation has on the mucosal immune response in the gut. Previous studies have not addressed the impact of vitamin A supplementation on the production of monocyte chemoattractant protein 1 (MCP-1), an essential chemokine involved in pathogen-specific mucosal immune response. Fecal MCP-1 concentrations, determined by an enzyme-linked immuno absorption assay, were compared among 127 Mexican children 5-15 mo of age randomized to receive a vitamin A supplement (<12 mo of age, 20,000 IU ...
