Evaluation of the virulence markers in the clinical isolates of citrobacter species: the first report from India.

Background: Citrobacter, a gram negative bacillus, is emerging as one of the major pathogens in hospital settings, with a potential to cause serious infections. Virulence markers are the factors which enhance the survival ability of the micro-organisms. Among the gram negative bacilli, these have been extensively studied in Escherichia coli.

The prevalence of nasal carriage of Staphylococcus aureus among healthcare workers at a tertiary care hospital in assam with special reference to MRSA.

Background: The recent years have witnessed the increasing resistance of Staphylococcus aureus to many antimicrobial agents. The most notable example is the emergence of Methicillin-resistant Staphylococcus aureus (MRSA), which was reported just one year after the launch of methicillin. The ecological niches of the S.

HIV and malnutrition: effects on immune system.

HIV or human immunodeficiency virus infection has assumed worldwide proportions and importance in just a span of 25 years. Continuous research is being done in many parts of the world regarding its treatment and vaccine development, and a lot of money has flown into this. However, fully understanding the mechanisms of immune depletion has still not been possible.

Comparison of an automated system with conventional identification and antimicrobial susceptibility testing.

The present study was designed to compare a fully automated identification/antibiotic susceptibility testing (AST) system BD Phoenix (BD) for its efficacy in rapid and accurate identification and AST with conventional manual methods and to determine if the errors reported in AST, such as the (very major errors) VME (false susceptibility), (major errors) ME (false resistance), and (minor errors) MiE (intermediate category interpretation) were within the range certified by FDA. Identification and antimicrobial susceptibility test results of eighty-five clinical isolates including both gram-positive and negative were compared on Phoenix considering the results obtained from conventional manual methods of identification and disc diffusion testing of antibiotics as standards for comparison. Phoenix performed favorably well.

Direct inoculation on Phoenix panels for identification and antimicrobial susceptibility from positive BACTEC cultures: first study from India.

Purpose: This was a prospective study planned in a super-specialty hospital in Delhi to reduce turnaround times of identification-susceptibility results of positive blood cultures.

Materials And Methods: One hundred consecutive single morphology non-duplicate cultures were inoculated on Becton Dickinson Phoenix™ panels by growth recovered directly from liquid BACTEC™ media and after pure growth on solid media.

Results: Complete concordance was observed in 72.

Plexiform fibrohistiocytic tumor in the submandibular region: A rare diagnosis.

Plexiform fibrohistiocytic tumor (PFHT) is a rare mesenchymal neoplasm of intermediate malignancy, first reported by Enzinger and Zhang in 1988 [1]. It mainly affects children and young adults and preferentially involves the upper extremity [1, 2].We report a rare case in the submandibular region which was diagnosed on histopathology.
