Marine endosymbiotic fungi Aspergillus ustus (MSF3) which produce high yield of biosurfactant was isolated from the marine sponge Fasciospongia cavernosa collected from the peninsular coast of India. Maximum production of biosurfactant was obtained in Sabouraud dextrose broth. The optimized bioprocess conditions for the maximum production was pH 7.0,(More)
An endosymbiotic Pseudomonas sp. (MSI057), which could produce high yields of lipase, was isolated from marine sponge Dendrilla nigra, collected from the peninsular coast of India. Maximum production of enzyme was obtained in minimal medium supplemented with 1% tributyrin. Catabolite repression was observed when the medium was supplemented with readily(More)
Leptospirosis is recognized as the most widespread zoonosis with a global distribution. In this study, the antigenic variation in Leptospira interrogans and Leptospira borgpetersenii isolated from human urine and field rat kidney was preliminarily confirmed by microscopic agglutination test using monoclonal antibodies, and was further subjected to(More)
The sponge-associated actinomycetes were isolated from the marine sponge Dendrilla nigra, collected from the southwest coast of India. Eleven actinomycetes were isolated depending upon the heterogeneity and stability in subculturing. Among these, Nocardiopsis dassonvillei MAD08 showed 100% activity against the multidrug resistant pathogens tested. The(More)
Leptospirosis, a zoonosis of global importance and it is underreported in India and more than 50,000 severe cases are reported each year. Here we present the evaluation of 16S rRNA based nested PCR assay for the rapid identification of human leptospires using serum and urine samples. The study includes 261 suspected cases for leptospirosis with different(More)
Marine endosymbiontic Roseobacter sp. (MMD040), which produced high yields of protease, was isolated from marine sponge Fasciospongia cavernosa, collected from the peninsular coast of India. Maximum production of enzyme was obtained in Luria-Bertani broth. Catabolite repression was observed when the medium was supplemented with readily available carbon(More)
PURPOSE The study aimed to identify the status of HPV infection among young sexually unexposed girls from Tiruchriapalli district, Tamilnadu, India. METHODS The distribution of HPV genotypes was evaluated by PCR DNA genotyping after self sampling from 246 study subjects. RESULTS Positivity for HPV DNA was reported among 9.2% of the study subjects. The(More)
The surveillance in Chennai identified 134 children and 443 adults clinically suspected for leptospirosis. Of these, 35 (26.1%) children and 118 (26.6%) adults had laboratory confirmed diagnosis for leptospirosis. The paediatric leptospirosis exhibited a higher frequency of classic features of Weil's disease. The prevalent serovar encountered was(More)

Leptospirosis is now acknowledged as the most widespread zoonoses in the world. Hundreds of cases occur in India every year accounting for considerable morbidity and sizable mortality. Several studies have delineated the epidemiology, pathology and variable clinical features of this condition. The present study comprises the importance and utilization of(More)
