How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Marine Streptomyces species are underexplored for their pigment molecules and genes. In this study, we report the genome of the undecylprodigiosin biosynthesizing gene cluster carrying Streptomyces sp. strain BSE6.1, displaying antioxidant, antimicrobial, and staining properties. This Gram-positive obligate aerobic bacterium was isolated from the c...
Background & objectives: The biological spectrum of leptospirosis ranges from acute undifferentiated febrile illness to severe fatal syndrome or a combination of syndromes. Diagnosis on clinical grounds alone is difficult and depends on laboratory support. However, no confirmatory tests are available, which is rapid and can be performed with minim...
Typically, humans contract leptospirosis through exposure to soil or water contaminated with the urine of infected animals. Specifically, people working in inundated fields, engaged in aquatic sports, or exposed to contaminated floodwater after periods of heavy rainfall bear the risk of contracting leptospirosis. There is a critical gap in the know...
A 27-year-old male presented in the OPD of Naval Hospital in Port Blair, Andaman Islands, India, in 2011 with a history of low-grade fever associated with malaise and a pruritic skin rash. Case 2 – A 17-year-old male student reported to the OPD at Naval Hospital, Kochi Kerala, India, in August 2015. He presented with eruptions on both the palm and...
The present study is aimed to determine the draft genome of novel species of Zooshikella strain S2.1, a potential red pigmented strain isolated recently from the coastal sediment of Andaman and Nicobar Islands, India. This Gram negative, rod shaped aerobic bacterium produces pink, yellowish-red and dark red with metallic green sheen pigmentation on...
Using PCR and sequencing, we found Plasmodium knowlesi in the malaria vector Anopheles sundaicus mosquito collected from Katchal Island in the Andaman and Nicobar Islands, India. We cannot rule out natural transmission of this parasite to humans through this mosquito species. An in-depth investigation is needed to prevent disease outbreaks.
Environment plays an important role in the distribution of Vector Borne Diseases, which influences vector-pathogen transmission cycle, encompassing the vector distribution, abundance and diversity. Arbo-viral pathogens respond to changes in environment at different transmission levels and upsurges when environment is altered. Mosquito biodiversity...
An upsurge of fever cases of unknown origin, but resembling dengue and leptospirosis was reported in Havelock, Andaman & Nicobar Islands, an important tourism spot, during May 2014. Investigations were carried out to determine the aetiology, and to describe the epidemiology of the outbreak. The data on fever cases attending Primary Health Centre (P...
There is a lack in research related to association of nonendosymbiont bacteria with Casuarina spp. Plant Growth Promoting Rhizobacteria (PGPR) nonendosymbiont bacteria such as Pseudomonas sp. and Bacillus sp. are long associated with their properties of heavy metal accumulation and plant growth promoting activity. This study focuses on heavy metal...
Lifestyle and dietary habits are crucial features that can alter the gut microbiome of humans. Humans, along with their gut microbes, have coevolved in order to sustain themselves in different environments. They were able to adapt themselves to the dietary sources available in their environment. The relation between humans and their gut microbiota...
Background An outbreak of hand, foot and mouth disease (HFMD) occurred in the Andaman Islands in 2013. Therefore, we aimed to identify the aetiological agent and to explore its genetic characteristics. Methods Clinical specimens were subjected to virus isolation, further confirmed by sequencing the partial VP1/2A region of enterovirus, and analyse...

Biology and pathogenesis of chikungunya virus (CHIKV) are not clearly established. Host factors play an important role in determining the progression and severity of the disease. Polymorphisms in the promoter region of CD209 gene (rs735239, rs4804803, rs2287886) and OAS1 (rs1131454 and rs10774671), OAS2 (rs15895 and rs1732778), and OAS3 (rs2285932...
A disease outbreak of A (H1N1) PDM09 was reported in Andaman and Nicobar islands in 2009 with an attack rate of 33.5% among settler population and 26.3% among the aboriginal Nicobarese tribe. During the ongoing outbreak of A (H1N1) PDM09 disease in different parts of the world, a subject working in Dubai city of Saudi Arabia, came to Port Blair, fo...
Actinobacteria are ubiquitous and known for its heavy metal resistance and antibiotic production. Antibiotic activity and metal resistance property of Casuarina equisetifolia associated actinobacteria were studied. The actinobacteria were screened for antagonistic activity against bacterial and fungal pathogens. Four strains identified as S.roseise...
This study aims to determine the clinical features and seasonal patterns associated with shigellosis, the antimicrobial resistance frequencies of the isolates obtained during the period 2006-2012 for 22 antibiotics, and the molecular characterization of multidrug-resistant strains isolated from endemic cases of shigellosis in the remote islands of...
A sudden upsurge of fever cases with joint pain was observed in outpatient department, Community Health Centre, Rangat during July-August 2010 in Rangat Middle Andaman, India. The etiological agent responsible for the outbreak was identified as Chikungunya virus (CHIKV), by using reverse transcriptase based polymerase chain reaction and IgM ELISA....
