Title of Seed grant project: Detection of common diarrheagenic bacterial and viral pathogens in faecal samples of paediatric by polymersae cahin reaction
Background: Diarrheal diseases are the primary cause of death among children below five years of age. Aetiology of diarrhoea differs depending on the country and region. Most of the clinical laboratories perform microscopy and culture which have reduced sensitivity and hence aetiology of diarrhoea goes undiagnosed. Accurate laboratory diagnosis of the diarrhoea causing agent is necessary to know the pathogen-specific burden of diarrhoeal disease and management of patients.

Material & methods: In this cross-sectional, in-vitro study done from 01-April-2019 to 31-March-2020 in the Department of Microbiology, Kasturba Medical College, Mangalore, stool samples of children (n=109) with ≥3 diarrheal episodes were cultured for bacterial pathogens. Total faecal genomic DNA & RNA was extracted using QIAamp Fast DNA Stool and QIAamp Viral RNA Mini Kits. Real time PCR (RT PCR) was done for the detection of bacterial and viral aetiological agents.

Results: Among the 109 stool samples screened by RT PCR, Shigella spp was detected in 16% (n=17), Rotavirus in 21% (n=23) and Salmonella spp. in 2% (n=2) of stool samples. Two samples had multiple pathogens namely Rotavirus and Shigella spp. However, by the conventional culture, we could isolate one each of Shigella flexneri & S.Typhi from two samples.

Conclusion: Shigella spp and Rotavirus were the predominant aetiology of diarrhoea in our study population. PCR was found to be a better tool when compared to culture as it could detect both viral and bacterial pathogens simultaneously. Further studies are necessary to screen for all the possible pathogens (bacteria, virus & parasite) in stool samples with a focus on the seasonal distribution of the pathogens causing diarrhoea in this part of the country.

Title of Seed grant project: Utility of serum procalcitonin and CD64 ratio expressed on neutrophill, lymphocyte and monocyte subsets in diagnosis of early Onset Neonatal Sepsis
The present study is a hospital-based prospective multidisciplinary study. Objectives of the study are a. To study the utility of flow cytometry (FCM) analysis of CD64 ratio expressed on neutrophil,lymphocyte and monocyte subsets in diagnosis of early onset neonatal sepsis(NS) in neonatal intensive care unit(NICU). b. To study role of serum C-reactive protein(CRP), hematological scoring system(HSS) and serum procalcitonin(sPCT) in the diagnosis of NS. c. To correlate CD64 expression,CRP,sPCT and blood culture with clinical findings. Inclusion criteria included study population of neonates born to those pregnant women who were considered high risk mothers due to various risk factors that contributed to development of NS and admitted for delivery. Neonates born to these mothers, will be assessed in the first 3 days of birth to look for EONS.

Various tests such as CBC,IT ratio,ANC, platelet indices, sPCT, CRP and blood culture have been used to diagnose neonatal sepsis either singly or in any combinations. These tests either lack sensitivity or specificity or tests like blood culture takes longer time which delays the initiation of antibiotic or results in usage of broad spectrum antibiotics. Thus, the need for a test for early diagnosis of NS that has got high sensitivity and specificity. CD64 expression is a rapid yet accurate method to detect early sepsis and when combined with sPCT can be a significant diagnostic tool. We believe that utility of CD64 to diagnose NS has implication on antibiotic stewardship for timely initiation or termination of antibiotic therapy in NICU.

Title of Seed grant project: Design and Evaluation of a Nanogel formulation for Bioflim based burn Infections
Design and evaluation of a nanogel formulation for biofilm based burn infections

The study was performed to identify the possible targets of bacterial signaling process that can be exploited to develop antibiofilm therapeutics. With the help of computational biology, we were successful in designing a hypothesis and screening the molecules available in the database. Since the procurement of these molecules were beyond the reach of our project similar molecules were synthesized in the laboratory. These molecules were tested in the lab and were found to be effective in standard organisms procured from national repositories a topical formulation was developed and tested on reference strains. However, due to the outbreak of the pandemic, the formulation could not be tested in the clinical isolates.

Title of Seed grant project: Screening for Abacavir Hypersensitivity by DNA Microarray among HIV sero-positive adult patients in a tertiary care hospital
HLA molecules are involved in induction and regulation of immune responses, but are associated with disease too. HLA-B*5701 allele carriage has been strongly associated with hypersensitivity reaction to abacavir (ABC) with up to 100% positive predictive value. Occurrence (<5%) of hypersensitivity reaction (HSR) has restricted the usage of ABC.A prospective study was conducted to assess the frequency of HLAB*57:01 allele carriage by DNA Microarray among 52 HIV-1 infected individuals attending HIV clinic and to document the usage of ABC and its adverse event profile. The mean age of the study subjects was 49 yrs, with majority of them males (67%). Antiretroviral therapy was started in 90% patients. The most frequent ART regimen (60%) instituted was a combination of 2 NRTIs and 1 NNRTI. Mean CD4+ lymphocyte cell count was 480 cells/cu.mm. HIV-1 viral load of less than 1000 copies/mL was found in 67% study subjects. HLA-B*57:01 carriage was seen in 2 (3.8%) patients who were not on ABC based ART regimen currently or in the past. Even though low sample size was a limitation, the frequency rate which we found reflects the prevalence rates found in earlier studies (ASSURE) including those from India.

The frequency of ABC usage in our hospital setting was found to be low. During the study period, 10 patients were found to be on ABC based ART regimen, including 6 patients for whom HLAB*57:01 testing was performed. Tenofovir induced renal adverse effects (50%), chronic kidney disease (30%) and hepatitis with dolutegravir based regimen (20%) were the reasons for introduction of ABC. None of the patients on ABC had experienced signs or symptoms suggestive of ABC-associated HSR.

Predicting the occurrence of ABC HSR or its avoidance through HLA-B*57:01 screening is possible. Considering the evidence of varied prevalence of HLAB*57:01 across different racial and ethnic populations and gender wise differences in allele carriage, it is appropriate that multi-centric studies across India may be planned to know the HLAB*57:01 prevalence rates across different geographical regions of our country among HIV-infected individuals. Cost can be a limiting factor for HLAB*57:01 screening which needs consideration. Kit based microarray testing seems to require relatively less technical expertise and also allows easy analysis of results compared to other molecular typing methods. Screening for HLA-B*5701 allele carriage among HIV-infected patients should be performed before initiation of therapy with ABC-containing regimens. There is further scope to work on the role of various HLA phenotypes and clinical outcomes in HIV infection in Indian settings.

Title of Seed grant project: Developing and evaluating the efficacy of a paper based rapid diagnostic test for dengue using zinc oxide quantum dots
Integration of medicine with technology is the solution for efficient and accelerated diagnostic outcomes to deliver better health care. Efforts are being taken by many researchers to develop economical and easy to use diagnostic assays for various clinical conditions including infectious diseases. Introduction of nanotechnology has been noticed as a major breakthrough in many such successful research initiatives. Usage of nanobiosensors are shown to be an excellent approach for a better diagnostic test. The objective of this project was to develop a paper-based dengue detection kit. In view of that, luminescent ZnO nanoparticles functionalized with specific anti NS1 antibody was synthesized. Luminescence spectra of the ZnO nanoparticles showed two peaks at 370 nm and 440 nm. The changes in the luminescence intensity with different amount of dengue positive serum was studied and compared with changes in the nanoparticle luminescence intensity with different amount dengue negative serum samples. It was observed that, after adding positive serum, luminescence intensity of the ZnO nanoparticles increased, which can be attributed to the binding of the NS1 antigen to the antibody. After adding negative serum, the luminescence intensity of the ZnO nanoparticles showed a decrease in intensity. This confirmed the possibility of using changes in the luminescence of ZnO nanoparticles for dengue detection. Further optimization and studies are required to understand these changes in the luminescence and to develop a dengue detection kit.

Title of Seed grant project: Utility of direct detection of mec A gene in clinical specimen for detection of Methicillin Resistant Staphylococcus aureus.
Background: S. aureus is implicated in skin, soft tissue infections and invasive infections like cellulitis pneumonia, endocarditis, bacteremia, septic shock. MRSA infections are associated with higher morbidity, mortality and higher costs MRSA: major cause of heath care associated infections (HA -MRSA) HA-MRSA rates have increased from 23.9% in 2013 to 30.2% in 2016 The alarming rise in the rates of HA- MRSA reported from this region necessitates the need for a DNA based assay PCR: easy, sensitive and specific method for detection of MRSA .

Objectives: To isolate and identify MRSA from clinical specimen , To detect mec A gene in the clinical specimen and To compare direct detection of mec A gene with detection in clinical isolate of Staphylococcus aureus

Methods: Cross sectional hospital based study Inclusion criteria: Invasive samples (blood,deep tissue pus, bronchoalveolar lavage, sterile body fluids )Sample size: 125. The samples were processed using standard methods. Identification of growth: Gram stain, catalase test &coagulase test. Antibiotic sensitivity testing: Modified Kirby-Bauer disk diffusion method. The results were interpreted with CLSI recommendations. Cefoxitin (30μg) disk diffusion method: methicillin resistance in S.aureus. DNA Extraction: QIAamp blood and tissue kit (QIAGEN) and alkali lysis for the extraction from BacT alert broth and Real time PCR was performed.

Results: 110 clinical non duplicate samples were included in the study The prevalence of MRSA : 29%.74.6% : skin and soft tissue infections,11% from blood stream infections , 10.4% from osteomyelitis cases, 4% respiratory secretions Antibiotic resistance rates of MRSA ciprofloxacin(75%),clindamycin(51.1%), trimethoprim sulfamethoxazole (59.1%) and erythromycin( 62.5%). Vancomycin (0%). Real time PCR Sensitivity: 97% Specificity: 98% PPV:94% ,NPV : 98% (With culture as gold standard )

Conclusion: This study demonstrated the potential utility of real-time PCR for the detection of S. aureus and MRSA directly from clinical cultures allowing for rapid same day detection. We used Gram stain results as criteria for sample selection. Rapid detection of MRSA would assist in better patient management, in terms of accurate antimicrobial treatment, help in cohorting infected from uninfected patient to prevent spread.

Title of Seed grant project: Molecular Detection and Characterization of Carbapenemase Resistance Gram Negative Bacteria (Cr-Gnb) among Patients with Sepsis
Objective: The present study was aimed at elucidating the epidemiology of bacterial sepsis, with a special emphasis on proportion of infections caused by Carbapenem-Resistant Gram-negative bacteria (CR-GNB) and to evaluate the diagnostic accuracy of broad-range PCR for the diagnosis of bacterial sepsis in comparison with automated blood culture system at a university hospital in South India.

Methods: A prospective study was undertaken from February 2017 - January 2018. Adult patients with the diagnosis of sepsis care were recruited. Baseline clinical, epidemiological, and laboratory data were recorded. A total of 100 consecutive whole blood samples (2-3ml) were collected and subjected to 16S rRNA PCR using specific primers and automated culture by standard protocol. Samples which were positive for 16S rRNA were sequenced to identify the organism and where further processed to determine the carbapenem resistance genes such as blaVIM, blaKPC, blaIMP,blaOXA, based on multiplex PCR approach.

Results: 130 eligible subjects were included in the study with mean age of 55.9±16 years. The mean SOFA score at the time of admission was 9.9±2.7. Bacterial etiology of sepsis was established in 40.7% of cases and 24% were caused by MDR pathogens. Carbapenem resistance was observed in 37% of the Gram-negative isolates. Escherichia coli (34.1%) was the leading pathogen. Overall, the 28-day mortality in ICU was 40%. The diagnostic sensitivity and specificity of the 16s rRNA PCR were 89.3% and 94.3% respectively. Of 46 carbapenem resistance isolates, 58.7 % isolates harboured one or more carbapenemase genes. New Delhi metallo-β-lactamase (52%) types were the most predominant genes detected.

Conclusions: The study focuses on the heterogeneity of sepsis cases diagnosed at a tertiary care center in India highlighting the basic demographics, clinical presentations and risk factors for mortality. NDM was found to be the most prevalent carbapenemase gene among clinical isolates. The 16S rRNA PCR proved to be rapid method for detection of bacterial pathogens in whole blood from sepsis patient. It may be a valuable tool in the diagnostic armamentarium for differentiating bacterial infection from others and starting empiric treatment.

Title of Seed grant project:Microbial synergy and altered virulence in polymicrobial biofilms
Diabetic foot ulcers (DFUs) are one of the most serious and long-term complications associated with diabetes with approximately 16% of the diabetic patients developing foot ulcers at least once in their life time (IDF, 2019). Infected DFU are commonly associated with complex polymicrobial communities known as biofilms. Biofilms typically comprise of extracellular polymeric matrix where clusters of bacteria remain adhered to an abiotic or biotic substrate. It is well documented that chronic wound infections are biofilm-mediated (James et al., 2008) and biofilm production facilitates the persistence of antibiotic resistant isolates. In addition to providing bacteria the environmental protection, nutritional requirements, and improved cell-to-cell communication, biofilms also provide bacteria with increased antibacterial resistance, and increased virulence (Costerton et al., 2003; Trøstrup et al., 2013) thereby predisposing them to delayed wound healing (Zhao et al., 2010). Treating biofilm infection caused by multidrug resistant bacteria is a major and daunting challenge considering that antibacterial drug development has not seen much success recently. Our study reports the biofilm forming capabilities of the dominant bacterial isolates obtained from DFUs along with their resistant profiles against various clinically relevant antibiotics. The study also looks into major virulence factors and pathogen–pathogen interaction at the genetic level in biofilm communities and strategies to combat multi drug resistance in these bacteria with the help of naturally occurring phytocompounds thereby aiding better management of DFUs in diabetic patients.
