Abstract
Background & Objective: Enterococcus is one of the notorious organism causing nosocomial infections.
Several virulence factors have been described from enterococci that enhance their ability to colonize patientís tissue,
increase resistance to antibiotics and aggravate the infection outcome. Therefore the study was carried out to
investigate virulence factors among the enterococci isolated from different clinical samples. Methodology: Total 154
enterococcus species were isolated and were identified by conventional bacteriological method as well as by Vitek-2
compact system. The presence of certain virulence factors namely hemolysin, haemagglutination, gelatinase
production and biofilm formation were detected and data was statistically analyzed. Results: E. faecalis was the
commonest isolate (147) followed by E. faecium (7). Maximum number of isolates were from urine 65(42.20%)
followed by pus 58(37.66%). The results of detection of virulence factors revealed 15.58% strains with gelatinase
production, 34.41% with haemagglutination property, 35.71% showed hemolysin production and 55.84% strains
showed biofilm production by microtitre assay plate method. Conclusion: All the markers studied are the potential
virulence markers for the enterococci. Biofilm formation is the crucial virulence factor that enhances the ability of
pathogen to cause severe infections. Inhibiting the action of such virulent factors or blocking biofilm formation may
provide alternative method of therapy. [Patil S NJIRM 2016; 7(3):7-11]

Key words: Biofilm, Enterococcus, virulence.

List of Journals Indexed for MEDLINE

The List of Journals Indexed for MEDLINE publication ceased with the 2008 edition. The NLM Catalog can be used to obtain a list of currently indexed MEDLINE titles; select the Limit for Current Subsets called "Currently indexed in MEDLINE."

The List of Serials Indexed for Online Users online publication is designed to provide bibliographic information for serials from which articles are indexed with the MeSH® vocabulary and cited in MEDLINE®, the backbone of the NLM PubMed® database. More detailed bibliographic data and information about indexing coverage for serials cited in MEDLINE/PubMed can be found in LocatorPlus®, the NLM online catalog, and the NLM Catalog, an Entrez database.

Journals Recently Accepted by NLM for Inclusion in MEDLINE lists titles selected by LSTRC which meets three times per year in February, June, and October. Results from those meetings appear online about six weeks after each meeting, both on the Web page and in the NLM Catalog.

Previous print versions of the List of Journals Indexed for MEDLINE might be available from the U.S. Government Printing Office (GPO). Information about ordering documents from GPO is available at http://www.nlm.nih.gov/pubs/pubcat.html#ordering.
