Probiotics
V Gupta, R Garg
July-September 2009, 27(3):202-209
DOI:10.4103/0255-0857.53201  PMID:19584499
The term "probiotic" was first used in 1965, by Lilly and Stillwell, to describe substances secreted by one organism which stimulate the growth of another. The use of antibiotics, immunosuppressive therapy and irradiation, amongst other means of treatment, may cause alterations in the composition and have an effect on the GIT flora. Therefore, the introduction of beneficial bacterial species to GI tract may be a very attractive option to re-establish the microbial equilibrium and prevent disease. Prebiotic is a non-digestible food ingredient that confers benefits on the host by selectively stimulating one bacterium or a group of bacteria in the colon with probiotic properties. Both probiotics and prebiotics are together called as Synbiotics. Various bacterial genera most commonly used in probiotic preparations are Lactobacillus, Bifidobacterium, Escherichia, Enterococcus, Bacillus and Streptococcus . Some fungal strains belonging to Saccharomyces have also been used. Probiotics have been shown to be effective in varied clinical conditions- ranging from infantile diarrhoea, necrotizing enterocolitis, antibiotic-associated diarrhoea, relapsing Clostridium difficle colitis, Helicobacter pylori infections, inflammatory bowel disease to cancer, female uro-genital infection and surgical infections. Lactobacillus rhamnosus strain GG has proven beneficial affects on intestinal immunity. It increases the number of IgA and other immunoglobulins secreting cells in the intestinal mucosa. It also stimulates local release of interferons. It facilitates antigen transport to underlying lymphoid cells, which serves to increase antigen uptake in Peyer's patches. Probiotics are live microorganisms, so it is possible that they may result in infection in the host. The risk and morbidity of sepsis due to probiotic bacteria should be weighed against the potential for sepsis due to more pathological bacteria and the morbidity of diseases for which probiotic bacteria are being used as therapeutic agents. Also, future, well-designed placebo controlled studies with validated results are required for ascertaining the true health benefits of probiotics The important point in this regard is careful selection of the probiotic agent, its dose standardization and a thorough knowledge of its beneficial effects.

C Rodrigues, S Shenai, M Sadani, N Sukhadia, M Jani, K Ajbani, A Sodha, A Mehta
July-September 2009, 27(3):217-221
DOI:10.4103/0255-0857.53203  PMID:19584501
Aim: To evaluate the performance of an automated BACTEC MGIT 960, a non-radioactive, non-invasive liquid culture system for cultivation of M. tuberculosis complex in terms of recovery rate and time. Materials and Methods: From March 2005 to December 2007, 14,597 specimens were processed using the MGIT 960 system and the results were compared with conventional L.J medium. We standardised r-nitro benzoic acid (PNBA) assay on MGIT 960 TB system for identification of M. tuberculosis complex and evaluated its usefulness by comparing the results with an in-house molecular assay and sequencing. Results and Discussion: Of the total 6143 (42%) isolates positive for M. tuberculosis complex, 6015 (41%) were positive by MGIT 960 TB system. In contrast, 3526 (24%) M. tuberculosis complex isolates grew on the conventional L.J medium. The mean turn around time for mycobacterial growth in smear-positive specimens was nine days for MGIT 960, and 38 days for L.J. medium whereas in smear negative specimens it was 16 days by MGIT vs. 48 days by L.J. Conclusion: MGIT 960 system with PNBA assay for identification of M. tuberculosis complex is a rapid and useful method in laboratories processing a large number of specimens.

AIDS - associated parasitic diarrhoea
DR Arora, B Arora
July-September 2009, 27(3):185-190
DOI:10.4103/0255-0857.53199  PMID:19584497
Since the advent of human immunodeficiency virus infection, with its profound and progressive effect on the cellular immune system, a group of human opportunistic pathogens has come into prominence. Opportunistic parasitic infection can cause severe morbidity and mortality. Because many of these infections are treatable, an early and accurate diagnosis is important. This can be accomplished by a variety of methods such as direct demonstration of parasites and by serological tests to detect antigen and/or specific antibodies. However, antibody response may be poor in these patients and therefore immunodiagnostic tests have to be interpreted with caution. Cryptosporidium parvum , Isospora belli , Cyclospora cayetanensis , Microsporidia, Entamoeba histolytica and Strongyloides stercoralis are the commonly detected parasites. Detection of these parasites will help in proper management of these patients because drugs are available for most of these parasitic infections.

I Gandhoke, R Aggarwal, SA Hussain, ST Pasha, P Sethi, S Thakur, S Lal, S Khare
July-September 2009, 27(3):222-225
DOI:10.4103/0255-0857.53204  PMID:19584502
Background: Samples from babies exhibiting clinical symptoms suggestive of congenital infection are referred regularly to NICD, New Delhi,, from Government Hospitals located in Delhi and a home for abandoned children (Palna), for the diagnosis of etiological agents like toxoplasma, rubella, CMV and herpes. Blood samples of mothers of most of the affected babies are also received. Objective: Evaluation of rapid and accurate technique for the diagnosis of congenital CMV infection. Materials and Methods: One hundred and twenty five blood samples suggestive of symptomatic congenital CMV infection were selected from samples received at NICD during the period June 2005-March 2007. A request to collect and send the urine samples of the selected babies was sent to the respective hospitals. Serum samples of the babies were tested for CMV-IgM antibodies using -capture ELISA. Mothers' serum samples were subjected to CMV-IgM and IgG class antibodies assay by commercial ELISA kits. DNA isolation and amplification was performed in urine samples and some of the serum samples using a commercial PCR kit for detection of HCMV. Blood and urine samples from 20 normal babies were included in the study. Results: Twenty Seven serum samples (21.6%) of infants, of the 125 tested, were positive for CMV-IgM antibodies. Twenty five samples (20%) showed amplification of CMV -DNA. All 25 samples positive for PCR were positive for CMV IgM antibodies. Sera of 73 mothers, out of 75 tested (97.3%), were positive for CMV IgG antibodies. However, none of them was positive for CMV IgM antibodies. Mothers of all 27 positive babies were positive for CMV-IgG antibodies. Serum and urine samples from 20 normal babies were negative for ELISA and PCR. Conclusion: -capture ELISA technique was found to be more sensitive than PCR (92.6%) for detection of congenital CMV infection. ELISA is also rapid, less cumbersome and cost effective for diagnosis of CMV infection.

July-September 2009, 27(3):257-258
DOI:10.4103/0255-0857.53211  PMID:19584510
An outbreak of food poisoning due to Salmonella enterica serotype Weltevreden ( S.weltevreden ) involving 34 students has been reported from a tertiary care hospital in Mangalore. The symptoms developed 8-10 hours, after consuming a non- vegetarian dish, probably fish, from an outside caterer. The identity of the organism was confirmed at Central Research Institute, Kasauli. This report emphasizes the geographical distribution of this organism in the Coastal Karnataka region. S.Weltevreden may be overlooked due to the biochemical similarity to S. Paratyphi B & S. Typhimurium.

S Chandy, H Boorugu, A Chrispal, K Thomas, P Abraham, G Sridharan
July-September 2009, 27(3):267-270
DOI:10.4103/0255-0857.53215  PMID:19584514
The clinical presentation of hantavirus infections in India is unclear. We report here a case of hantavirus infection in a 46 year old quarry worker presenting with fever, abdominal pain, jaundice, thrombocytopenia and renal dysfunction. Seroconversion and rising anti-hantavirus IgG titers were taken as evidence of hantavirus infection. Clinicians should consider hantavirus infections in the differential diagnosis of acute febrile illness along with scrub typhus, leptospirosis and dengue.

Detection of opportunistic DNA viral infections by multiplex PCR among HIV infected individuals receiving care at a tertiary care hospital in South India
J Sachithanandham, M Ramamurthy, R Kannangai, HD Daniel, OC Abraham, P Rupali, SA Pulimood, AM Abraham, G Sridharan
July-September 2009, 27(3):210-216
DOI:10.4103/0255-0857.53202  PMID:19584500
Purpose: Opportunistic viral infections cause increased morbidity and mortality among human immunodeficiency virus (HIV) infected individuals, especially those who are not on antiretroviral treatment. Early diagnosis of these opportunistic viruses will be able to reduce the risk of disease progression with appropriate intervention. Materials and Methods: Multiplex PCR was attempted to detect the opportunistic herpes viruses (HSV-1, HSV-2, VZV, EBV, and CMV), adenovirus and polyoma viruses (JC and BK) in three cocktails of PCR reactions. Subsequently, all the viruses detected were quantitated by testing using monoplex real time PCR. Whole blood samples collected between 2006 and 2007 from 68 treatment naοve HIV-1 infected and 30 normal healthy individuals were tested for these eight viruses. Among the 68 HIV -1 infected individuals 35 had CD4+ T cell count less than or equal to 200 while the other 33 had greater than 200 CD4+ T cells. Results: Among the 68 HIV-1 infected individuals, 49 (72%) were positive for EBV, 5 (7%) samples were positive for CMV. All the five CMV positive individuals had CD4+ T cell count of less than or equal to 200 cells/L. The mean EBV load among the individuals with a CD4+ T cells of less than or equal to 200 cells/L was 3.88 log 10 while among those with greater than 200 CD4+ T cells it was 3.75 log 10 . The mean CMV load was 6.98 log 10. Three samples were positive for both CMV & EBV. None of the samples was positive for HSV-1, HSV-2, VZV, Adenovirus, JC and BK viruses. Conclusions: In our study, multiplex PCR based detection system was found useful in detecting opportunistic viruses in HIV infected individuals. Though EBV is the most prevalent opportunistic viral infection among HIV infected individuals, there was no significant association between EBV load, CD4+ T cell counts and HIV-1 virus load. CMV was seen in HIV infected individuals with low CD4+ T cell counts (less than 200 cells/μL).

Role of Borna Disease Virus in neuropsychiatric illnesses : Are we inching closer ?
R Thakur, S Sarma, B Sharma
July-September 2009, 27(3):191-201
DOI:10.4103/0255-0857.53200  PMID:19584498
The biological cause of psychiatric illnesses continues to be under intense scrutiny. Among the various neurotropic viruses, Borna disease virus (BDV) is another virus that preferentially targets the neurons of the limbic system and has been shown to be associated with behavioural abnormalities. Presence of various BDV markers, including viral RNA, in patients with affective and mood disorders have triggered ongoing debate worldwide regarding its aetiopathogenic relationship. This article analyses its current state of knowledge and recent advances in diagnosis in order to prove or refute the association of BDV in causation of human neuropsychiatric disorders. This emerging viral causative association of behavioural disorders, which seems to be inching closer, has implication not only for a paradigm shift in the treatment and management of neuropsychiatric illnesses but also has an important impact on the public health systems.

Characterization of RPO B gene for detection of rifampicin drug resistance by SSCP and sequence analysis
SS Negi, U Singh, S Gupta, S Khare, A Rai, S Lal
July-September 2009, 27(3):226-230
DOI:10.4103/0255-0857.45364  PMID:19584503
Purpose: Because of the emergence of multidrug-resistant tuberculosis in recent times, the rapid detection of resistance to the first-line anti-tuberculosis drug rifampicin was felt worldwide. Accordingly, this study was conducted to evaluate the diagnostic potential of polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) for checking its utility as a rapid screening test for determination of rifampicin drug resistance. Materials and Methods: A total of 34 isolates of Mycobacterium tuberculosis ( M. tuberculosis ) (22 rifampicin resistant, 11 rifampicin sensitive and one control H37Rv) strains were analysed by PCR-SSCP and DNA sequencing within the 157-bp region of the rpo B gene (Ala 500 -Val 550 ). Results: Rifampicin resistance was detected successfully by PCR-SSCP in 20/22(90.90%) of rifampicin-resistant strains showing a total of nine different mutations in seven codon positions: codon 513 (CAA→CCA), 516 (GAC→GTC), 507 (GGC→GAC), 526 (CAC→GAC, TAC), 531 (TCG→TTG, TGG), 522 (TCG→TGG) and 533 (GTG→CCG). Two rifampicin-resistant strains showed an identical PCR-SSCP pattern with the wild type H37Rv; 77.27% rifampicin-resistant strains showed a single point mutation and 9.09% had no mutation. Three rifampicin-resistant strains showed characteristic double mutations at codon positions 526 and 531. Sensitivity and specificity were calculated as 90.90% and 100%. Conclusions: Rifampicin-resistant genotypes were mainly found in codon positions 516, 526 and 531. PCR-SSCP seems to be an efficacious method of predicting rifampicin resistance and substantially reduces the time required for susceptibility testing from 4 to 6 weeks to a few weeks.

OK Eser, K Ipci, S Alp, U Akyol, OF Unal, G Hascelik, L Sennaroglu, D Gur
July-September 2009, 27(3):237-241
DOI:10.4103/0255-0857.53206  PMID:19584505
Purpose: Chronic otitis media with effusion (OME) is the leading cause of hearing loss during childhood. In bacterial etiology of OME, the most frequent pathogens responsible are Haemophilus influenzae followed by Streptococcus pneumoniae and Moraxella catarrhalis . This study aimed at evaluating the accuracy of nasopharyngeal (NP) specimens in the identification of pathogens in the middle ear fluid (MEF) in patients with OME. Materials and Methods: In this cross sectional, case-control study, 95 MEFs and 53 NP secretion specimens were obtained from 53 children. As a control group, 102 NP specimens were taken from children having an operation other than an otological disease. Conventional culture methods and multiplex-PCR method have been used to determine the etiology of OME; NP carriage between cases and control groups were compared using conventional culture methods. Pearson Chi-Square and Fisher's Exact tests were used in statistical analysis. Results : Bacteria were isolated by culture in 37.9% of MEF specimens, 14.7% of which belonged to the group H. influenzae , S. pneumoniae and M. catarrhalis. PCR was positive in 30.5% specimens targeting the same pathogens. There was a two-fold increase in carriage rate of S. pneumoniae and H. influenzae in patients than controls for each pathogen. Conclusion: PCR is a more reliable method to detect middle ear pathogens in MEF in comparison with the conventional culture methods. The NP colonization wasn't found to be an indicator of the pathogen in MEF although middle ear pathogens colonize more in nasopharynx of diseased children.

July-September 2009, 27(3):254-256
DOI:10.4103/0255-0857.53210  PMID:19584509
This study has evaluated the performance of a rapid immunochromatographic test (ICT) device in detecting antibodies to Dengue virus (DENV) in a tertiary hospital in South India. Sera from hospital attendees, with requests for DENV antibody testing, were tested with the Panbio Dengue Duo Cassette and a reference antibody capture assay for the detection of IgM (Dengue IgM capture ELISA-National Institute of Virology, India) and IgG (Dengue IgG capture ELISA-Panbio Diagnostics Inc., Australia) antibodies. The ICT results were compared with results of antibody capture tests for the detection of the IgM and IgG antibodies, respectively. Accuracy indices for IgM and IgG detection, respectively were - sensitivity 81.8% and 87.5%, specificity 75.0%, and 66.6%, positive predictive value (PPV) 61.0% and 72.9% and negative predictive value (NPV) 89.6% and 83.9%. The device performs poorly in detection of IgM and IgG antibodies to DENVs and is not recommended for use as a stand-alone diagnostic test.

R Narang, P Narang, DK Mendiratta
July-September 2009, 27(3):247-250
DOI:10.4103/0255-0857.53208  PMID:19584507
Nontuberculous mycobacteria (NTM), important organisms in the Genus Mycobacterium and commonly present in the environment, are known to cause disseminated disease in AIDS patients. In this study, NTM were isolated from environment (soil and water) of the AIDS patients with disseminated NTM disease to know the prevalence of environmental NTM species and their correlation with clinical isolates from patients of the same area. Paraffin baiting technique was used to isolate NTM from environmental samples. Once isolated, subcultures were made on Lowenstein Jensen and Middlebrook 7H10 media and the species were identified using phenotypic and genotypic techniques. A total of 26 NTM isolates belonging to seven different species could be identified. Mycobacterium avium was the only species isolated from both clinical and environmental samples of the same patient; but the isolates did not match using PCR for IS 1311 and IS 1245 spacer sequences.

Drug resistant mutations detected by genotypic drug resistance testing in patients failing therapy in clade C HIV-1 infected individuals from India
AJ Kandathil, R Kannangai, VP Verghese, SA Pulimood, P Rupali, G Sridharan, P Grant, D Pillay, OC Abraham
July-September 2009, 27(3):231-236
DOI:10.4103/0255-0857.53205  PMID:19584504
Purpose: There has been an increase in the number of individuals administered antiretroviral therapy (ART) in India but treatment outcome is hampered by increasing development of drug resistance. Previous reports from India have shown M184V as the commonest mutation in treated individuals. However, there is no evidence for any protease mutations in these reports. This study was done to observe the common/unique mutational patterns observed in reverse transcriptase (RT) and protease (Pr) genes of clade C HIV-1 strains from individuals showing treatment failure in India. Materials and Methods: The assay was done by sequencing the Pr and RT genes of the HIV-1 strains from 18 individuals failing ART. Analysis was carried out using Stanford HIV drug resistance database (SHDB). The sequences were also submitted to the calibrated population resistance tool of SHDB and Rega HIV-1 sub typing tool. Phylogenetic analysis and quality control were performed with Mega 4. Results: Among the 20 strains, 19 showed resistance to both nucleoside reverse transcriptase inhibitors (NRTIs) and non-nucleoside reverse transcriptase inhibitors (NNRTIs), one strain to NNRTIs and five strains showed protease inhibitors (PI) resistance and 3-class resistance. The most common mutation conferring NRTI resistance was M184V (90%) while K103N (45%) was the most common mutation conferring NNRTI resistance. The M46I mutation was seen in 20% of the Pr sequences. Conclusion: Resistance testing to check the prevalence of drug resistance mutations that arise following failure of the first line regimen to establish guidelines for second line regimens in India is a must. Studies are needed to confirm if mutation patterns that arise among clade C following failure of ART are the same as for clade B strains.

Melioidosis, caused by Burkholderia pseudomallei , is an infectious disease of major public health importance in Southeast Asia and Australia. We report, for the first time from the Indian subcontinent, a case of melioidosis in a neonate, its clinical presentation, microbiological diagnosis, possible mode of transmission and outcome. A pre-term female baby developed respiratory distress soon after birth. The child was febrile, had tachypnea, grunting, normal heart rate with a low pulse volume and poor peripheral perfusion. Chest X-ray revealed right-sided bronchopneumonia. B. pseudomallei was isolated from the blood culture of the neonate collected aseptically. The neonate was successfully treated with meropenem.

Isolated pancreatic tuberculosis (TB) is extremely rare, even in countries where TB is endemic. The recent increased reporting of TB of the pancreas is related to a worldwide increase in TB and an increase in emigration from countries where TB is endemic into countries where more sophisticated healthcare and diagnostic facilities are available. Herein, we report an unusual case of isolated pancreatic region TB, which presented with dyspeptic symptoms and was diagnosed by ultrasonography-guided needle aspiration and computed tomography scan of the abdomen. This case is unique with regard to abundant bacterial load, as evident by Ziehl Neelsen staining and absence of evidence of TB elsewhere. Pancreatic TB should be considered as a differential diagnosis of a pancreatic mass and most patients have an excellent clinical response to standard antituberculosis regimens.

Cases of pulmonary aspergilloma without any predisposing factors are rarely reported. Clinical presentation varies from case to case. Here, we report a case of pulmonary aspergilloma in a 60-year-old male patient who was admitted to the Intensive Respiratory Care Unit with spontaneous pneumothorax. The patient had a history of dyspnea on exertion since 9 months and mild haemoptysis since the last 6 months. A computerised tomographic scan of the lungs showed a lesion in the left main bronchus along with obstructive emphysema of the right lung, moderate pneumothorax and mediastinal emphysema. Bronchoscopy was performed and the biopsy samples were processed for histopathological examination and culture on Sabouraud's dextrose agar, which yielded growth of Aspergillus flavus. Repeat sputum samples also yielded the growth of A. flavus . The patient responded to intravenous liposomaamphotericin B and intercostal drainage.

Tularaemia is a zoonotic disease caused by Francisella tularensis . In this report, we have presented an early stage case of tularemia with fever and pharyngitis and two cases from the same non-endemic region with typical lymphadenitis. All three patients were treated with non-specific medications in healthcare centres, the treatment being directed towards symptoms resembling those of upper respiratory tract infections. However, there was no regression in their complaints. Because the first case had been treated earlier, his lymphadenopaties regressed and there was no suppuration. The other two cases, which had been suspected to be exposed to the same pathogen based on their histories, were at a mild acute phase and presented to our clinic with typical lymphadenitis. The diagnoses of each of the three patients were made serologically. An early clinical recovery was achieved in the first patient with streptomycin (1 x 1 g/day im) and doxycyline (2 x 100 mg/day peroral) therapy. The therapy was prolonged to 4 weeks in the other two cases according to lymph node response and no complications occurring in their follow-ups. It can be concluded that tularaemia should be considered in the differential diagnosis of patients with fever, pharyngitis, conjunctivitis and cervical lymphadenopathies that do not respond to β -lactam antibiotics.

India continues to wage a battle against the human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) epidemic. Despite an array of preventive and control efforts directed against the disease, it continues to finds its way from the high risk groups to the general population. Women are more vulnerable to HIV/AIDS because of biological as well as socio-cultural factors. Microbicides appear to provide an attractive option as a means of protection to be used by women. At present, microbicide trials are in study phases I and II in India. The development of an ideal microbicide candidate which would be effective and confirms to user satisfaction poses a major challenge to researchers.
