13. Evaluation of the Polymorphisms Associated with Tandem Repeats for Pseudomonas aeruginosa Strain Typing
We report on the development of a scheme for the typing of Pseudomonas aeruginosa, multiple-locus variable number of tandem repeat (VNTR) analysis (MLVA). We first evaluated the polymorphisms of 201 tandem repeat loci selected from more than 3,000 such sequences present in strain PAO1 with a test collection of 12 genotypically distinct clinical strains. Seve

14. Multilocus Variable-Number Tandem Repeat Analysis Distinguishes Outbreak and Sporadic Escherichia coli O157:H7 Isolates
Escherichia coli O157:H7 is a major cause of food-borne illness in the United States. Outbreak detection involves traditional epidemiological methods and routine molecular subtyping by pulsed-field gel electrophoresis (PFGE). PFGE is labor-intensive, and the results are difficult to analyze and not easily transferable between laboratories. Multilocus v

15. Multilocus Variable-Number Tandem-Repeat Polymorphism among Brazilian Enterococcus faecalis Strains
Multilocus variable-number tandem-repeat analysis (MLVA) for seven genomic loci was developed for Enterococcus faecalis. MLVA and pulsed-field gel electrophoresis (PFGE) resulted in 37 and 31 genotypes among 83 strains, respectively. Both typing schemes were highly concordant (90.4%). MLVA is an excellent alternative to PFGE.

16. Heparin Binds to Murine Leukemia Virus and Inhibits Env-Independent Attachment and Infection
Certain glycosaminoglycans (GAGs), including heparin, inhibit infection by murine leukemia virus (MLV). We now show that this is due to inhibition of virus attachment independent of the interaction between viral envelope proteins (Env) and their cellular receptors. Heparin blocked the binding of both Env-deficient and amphotropic MLV (MLV-A) particles to NIH

17. Multiple-Locus Variable-Number Tandem Repeat Analysis of Dutch Bordetella pertussis Strains Reveals Rapid Genetic Changes with Clonal Expansion during the Late 1990s
Bordetella pertussis, the causative agent of whooping cough, has remained endemic in The Netherlands despite extensive nationwide vaccination since 1953. In the 1990s, several epidemic periods have resulted in many cases of pertussis. We have proposed that strain variation has played a major role in the upsurges of this disease in The Netherlands. Therefore,

19. Strain Typing of Borrelia burgdorferi, Borrelia afzelii, and Borrelia garinii by Using Multiple-Locus Variable-Number Tandem Repeat Analysis
Human Lyme borreliosis (LB) is the most prevalent arthropod-borne infection in temperate climate zones around the world and is caused by Borrelia spirochetes. We have identified 10 variable-number tandem repeat (VNTR) loci present within the genome of Borrelia burgdorferi and subsequently developed a multiple-locus VNTR analysis (MLVA) typing system for this

20. Use of Multilocus Variable-Number Tandem-Repeat Analysis for Typing Mycobacterium avium subsp. paratuberculosis
The etiology of Crohn's disease in humans is largely unknown. Clinical signs of Crohn's disease partly resemble the clinical picture of Johne's disease in ruminants caused by Mycobacterium avium subsp. paratuberculosis. Because of the high prevalence of these bacteria in (products of) ruminants and their remarkable thermostability, concern has been raised ab

21. Multiple-Locus Variable-Number Tandem Repeat Analysis Reveals Genetic Relationships within Bacillus anthracis
Bacillus anthracis is one of the most genetically homogeneous pathogens described, making strain discrimination particularly difficult. In this paper, we present a novel molecular typing system based on rapidly evolving variable-number tandem repeat (VNTR) loci. Multiple-locus VNTR analysis (MLVA) uses the combined power of multiple alleles at several marker

22. Identification and Characterization of Variable-Number Tandem Repeats in the Yersinia pestis Genome
Yersinia pestis, the infamous plague-causing pathogen, appears to have emerged in relatively recent history. Evidence of this fact comes from several studies that document a lack of nucleotide diversity in the Y. pestis genome. In contrast, we report that variable-number tandem repeat (VNTR) sequences are common in the Y. pestis genome and occur frequently i

23. Francisella tularensis Strain Typing Using Multiple-Locus, Variable-Number Tandem Repeat Analysis
Francisella tularensis, the etiological agent of tularemia, is found throughout the Northern hemisphere. After analyzing the F. tularensis genomic sequence for potential variable-number tandem repeats (VNTRs), we developed a multilocus VNTR analysis (MLVA) typing system for this pathogen. Variation was detected at six VNTR loci in a set of 56 isolates from C

24. Variable Number of Tandem Repeats in Salmonella enterica subsp. enterica for Typing Purposes
The genomic sequences of Salmonella enterica subsp. enterica strains CT18, Ty2 (serovar Typhi), and LT2 (serovar Typhimurium) were analyzed for potential variable number tandem repeats (VNTRs). A multiple-locus VNTR analysis (MLVA) of 99 strains of S. enterica supsp. enterica based on 10 VNTRs distinguished 52 genotypes and placed them into four groups. All
