Background

The aim of this site is to facilitate pathogenic bacteria strain genotyping essentially for epidemiological purposes. Typing is based on polymorphic tandem repeat typing (MLVA). This site takes advantage of MLVA properties to provide a simple service for high resolution isolate identification. The service is provided "as is" to the user’s own risks. The user is solely responsible for the interpretation of the results. The site provides essentially 2 services. The initial service is to make (...)

What is this site useful for ?

On this site you can do two main things : 1-you can query public databases with your MLVA data produced according to the appropriate protocol (usually described on the corresponding data base support site and/or publications) 2-you can make your own MLVA databases Of course the second part is one major interest of this site. You do not need any authorisation from us to do this, and the quality and eventually value of what you will produce is your responsibility. A database you make is (...)

FAQ

What is a csv data file and how can I make one ? A csv text file is a file in which "fields" or data values are separated by commas ("csv" stands for "commas separated values"). Commas are ";".

What you need to know to get started

From the MLVA databases page at http://mlva.u-psud.fr you see on the left end side a list of "public databases". You can query these public databases, without a login and pwd. Usually, such databases will correspond to published data. Often, databases for on-going projects also exist, you need to contact the owner(s). A link to this list of "private databases" is provided. There are many such databases, because anyone with a login can create its own database, and manage his own sharing (...)

Policy

The primary purpose of the MLVAnet website is to provide general assistance to the use of the MLVA genotyping databases, hosted in the Paris University in Orsay or by other associated sites. The website is developed by Orsay Paris-Sud University. The typing data and epidemiologic data accessible on these different sites is the property of the submitters and cannot be used without the authorisation of the corresponding community. Creation and development of MLVA databases is possible for (...)
