Current Highlight and new addition of the department: Identification of bacteria/fungi/Mycobacteria within 5 minutes by Matrix-assisted laser desorption ionization–time of flight mass spectrometry (MALDI-TOF MS)
Department of Clinical Microbiology and Immunology at Sir Ganga Ram Hospital is pleased to introduce a revolutionary and innovative technology, MALDI-TOF MS, for the first time in a healthcare setting in the country, which aims to drastically reduce the identification time of organisms at species level to 1-2 minutes.
Principle of MALDI-TOF
The principle of Vitek-MS consists of ionizing chemical compounds to generate charged molecules and to measure their mass-to-charge ratio (m/z).
- Laser light causes the sample and matrix to volatilize.
- The ions formed are accelerated by a high voltage supply and then allowed to drift down a flight tube where they separate according to their mass
- Ionised mass is detected at the end of the flight tube by a particle detector
UTILILTY of MALDTI-TOF
- The identification of clinically significant organisms within few minutes as opposed to the 15 to 24 hrs time frame previously required with traditional overnight methods. Studies suggest that same-day bacterial identification can have a demonstrable clinical impact (lowering of mortality rates by initiating appropriate therapy) and are associated with significant cost savings for hospitals and patients.
- MALDI-TOF aids in rapid identification of difficult to identify organisms accurately like Nocardia spps., Haemophilus spps., anaerobic bacteria and filamentous & yeast fungi, Mycobacteria spps.,including atypical mycobacteria. Molecular methods, though, able to identify most of the organisms, are still evolving, expensive and laborious to be used for routine identification. MALIDI-TOF gives speed, accuracy and economy to identify these myriad organisms in a matter of few minutes.
- MALDI-TOF technology, apart from being robust, is compatible with futuristic Hospital Infection Control software, Myla. The interfacing of MALDI-TOF with Myla will help in generation of real time data for monitoring and alerting of any unusual pattern of bacteria in hospital wards and ICU e.g., outbreak of multidrug resistant (MRSA, VRE) organisms. This technological advancement will help the clinical microbiology laboratory in supporting management and control of health-care-associated infections (HAI) timely and more effectively.
- Automated ELISA work station
- Profiles for viral hepatitis (A, B, C and E). Ours is probably the only laboratory in the city that confirms hepatitis B virus surface antigen positive cases with a confirmatory neutralisation assay.
- Rapid diagnostic tests for all major infectious diseases like: HIV (all HIV positives are confirmed with 3 different ELISAs as per WHO recommendations).
- Rapid test for Typhoid fever, cryptococcal meningitis, bacterial meningitis, leptospirosis cysticercosis, hydatid disease, etc.
- ELISA for dengue fever, mycobacterial infections, amoebiasis, etc.
- ELFA (VIDAS) for C. difficile toxin assay.
- Quantiferon TB Gold in tube assay.
- Weil felix test for typhus, IgM ELISA for scrub typhus.
- Legionella Urinary antigen
- Digital Photomicrograph system for documentation of the microscopic findings. Such prints can be attached with the reports of the patients for objective evaluation.
- Direct Immuno fluorescence assay for Pneumocystis carinii
- Direct fluorescence assay for M. tuberculosis, fungi.
The efficiency of the laboratory in meticulously following internationally recommended techniques, adhering to various elaborate inbuilt control protocols and guidelines reflects in the accurate test results. Our laboratory has been accredited by NABL (ISO 15189:2003) since 2004. Successful annual NABL audit in 2011 and continuation of certificate till 2012 has been granted to our department in fields of bacteriology, mycology, mycobacteriology, serology, virology, molecular biology and parasitology.
Following are the highlights of our rigorous quality control practices.

The training includes daily bench work according to the posting schedule, presentation of cases in the clinical meeting, review of literature in journal club, seminars and attending other academic activities of the hospital. The seminars/tutorials/journal clubs are held on every Wednesday & Saturday. The students maintain the contents of the seminars and case reports as presented in the meeting. The students also co-ordinate the practical tutorials for technicians in which they give a brief talk on a specific topic, which is then discussed with the help of a moderator.
- Microbiology Newsletter :Our department has been taking out 6 monthly newsletter for Microbiology (bacteriology and mycology, serology, molecular biology & mycobacteriology) since 1995, first of its kind in India. Apart from having wide circulation among medical fraternity, these newsletters are also hosted on the website of SGRH for open access to all. The data from the newsletter has also been instrumental in formulating the antibiotic policy of our hospital which is updated from time to time. The department Chairman is also the founder editor of SGRH Newsletter since 1997. Both newsletters are web hosted and appreciated by readers across the country and aboard.This represents the ultimate transparency in working of the department. The newsletters also serve as a yearly audit of the department besides getting subjected to preview.
- Academically active faculty attending national and international conferences and presenting papers. They receive invitation for participation in W.H.O. activities and other seminars and symposia. Our Chairman also has the distinction of having got listed in the Marquis Who's Who in Science and Engineering (USA) directory for the year 1998-99. He is also the editor of Sir Ganga Ram Hospital Newsletter.
- Weekly In-house CME for the technical staff as per the schedule.
Hospital Infection Control
The department of Clinical Microbiology & Immunology is active member of hospital infection control committee (HICC). Hospital Infection Control Committee meets twice a month of which Dr. C. Wattal is the member secretary since last twenty years. Under HICC, the department carries out surveillance of hospital acquired infection (HAI) with the help of infection control nurses. Laboratory records are analyzed to determine the rate of infection in various areas of the hospital. Presently the surveillance is passive and is based on the laboratory records of culture positive cases. Based on this, crude infection rates (CIR) are calculated for important HAI. This helps in establishing endemic baseline infection rates, identifying outbreaks and monitoring susceptibility patterns. Apart from surveillance of HAI, the environmental surveillance activities are also carried out which includes air sampling in critical and semi critical areas. In addition to this, the infection control practices are also routinely monitored by the following activities
- Sterility checks of the new pre sterilized articles purchased by the hospital or the efficacy of the new disinfectants to be purchased is done when desired by the concerned authority.
- I n use test of the disinfectants used in the hospital and sterility of Total Parenteral Nutrition (TPN) or any other sterile solution in use prepared in house.
- Monitoring of CSSD (3M Attest system)
- Surveillance of pathogens.
- Infection control policies in force: disinfection, surveillance, isolation, antibiotic and chemoprophylaxis.
- Active participation of Hospital Infection Control Nurse.
- Nurses from School of Nursing attend the department during their course.
- Yearly antibiogrammes published in the Microbiology Newsletter
- Continuing medical education (CME) programme held regularly.
- HMA award for the HIC committee in 2002.
