Wolbachia bacteria, being filarial parasite symbiont have been implicated in a variety of roles, including development, fecundity and the pathogenesis of the filarial infections. Among various strategies used in the treatment of experimental filariasis, the elimination of symbiont Wolbachia seem to offer an efficient means of curing the disease. The(More)
The antifilarial activity of two coumarin derivatives (A, B) and three glycosyl amine derivatives (D, E, F) was evaluated against a subperiodic strain of human lymphatic filarial parasite Brugia malayi by the intraperitoneal route at 50 mg/kg for 5 consecutive days. Of these, the two sugar derivatives (D and E) were selected for evaluation by the oral route(More)
The enthesitis-related arthritis (ERA) category of juvenile idiopathic arthritis (JIA) is the most common category in India. HLA B27 has a high prevalence in ERA, and ILAR classification includes it in exclusion criteria for other categories, but due to its cost, it is not routinely done. We undertook this study to assess the prevalence of HLA B27 in ERA(More)
Particulates of nanometers size have occupied a significant area in the field of medicinal and agricultural purposes due to their large surface-to-volume ratio and exceptional physicochemical, electronic and mechanical properties. Myconanotechnology, an interface between mycology and nanotechnology is budding nowadays for nanoparticle-fabrication using(More)
The altered cellular gene expression profile is being hypothesized as the possible molecular basis navigating the onset or progress of various morbidities. This hypothesis has been evaluated here in respect of Cr 6+ induced toxicity. Several studies using gene microarray show selective and strategic dysregulations of cellular genes and pathways induced by(More)
A compound of the coumarin class, 4-methyl-7-(tetradecanoyl)-2H-1-benzopyran-2-one, was evaluated for antifilarial activity against the human filarial parasite, Brugia malayi (sub-periodic strain) in Mastomys coucha. The test compound brought about a 24.4% reduction in circulating microfilaremia on day 8 after initiation of treatment when administered by(More)
The precise and potential contribution of Toll-like receptors (TLRs) signaling pathways in fighting parasitic infections of Leishmania spp., an intracellular protozoan parasite, has gained significant attention during the last decades. Although it is well established that TLR9 recognizes CpG motifs in microbial genomes, the specificity of the CpG DNA(More)
The chloroform methanol (1:1) extract of an unidentified green zoanthus (Phylum Coelenterata, Class Anthozoa) showed promising in vitro adulticidal activity with a lethal concentration of 125 μg/ml on Brugia malayi. This extract brought about a 52.2% reduction in circulating microfilariae of B. malayi when administered to infected Mastomys coucha at 250(More)
Visceral leishmaniasis (VL) caused by the parasite Leishmania donovani, is a potentially fatal disease. It is characterized by prolonged fever, enlarged spleen and liver, substantial weight loss and progressive anemia. Available drugs are toxic, costly and require prolonged treatment duration viz; 28 days of oral treatment with miltefosine, 30 days infusion(More)
The discovery of the endosymbiont Wolbachia, which has a mutualistic relationship with filarial nematodes, and its importance in filarial parasite biology has provided a lead for developing novel chemotherapeutic agents against human filariasis. Wolbachia also appears to be involved in immunopathological responses as well as adverse reactions after(More)
