Dengue virus infection is prevalent in tropical and sub-tropical regions of the world, which is fatal if untreated symptomatically. Emergence of new genotype within serotypes led to enhanced severity. The objective of the study is to identify the molecular characteristics of the DENV circulated during 2017 outbreak in Tamil Nadu, India and, to investigate the role of inflammatory cytokines in different ‘serotypes’ and in ‘dengue severity’. A total of 135 suspected samples were tested for DENV infection using IgM, IgG and qPCR assay; where 76 samples were positive for DENV and analysed for twelve inflammatory cytokines using ELISA. Serotyping shows 14 DENV-1, 22 DENV-2, 7 DENV-3 and 33 DENV-4, where DENV-4 was predominant. Among seventy-six, forty-two isolates were successfully sequenced for C-prM region and grouped. A lineage shift was observed in DENV-4 genotype. Irrespective of serotypes, IFNγ was significantly elevated than control and in primary infection indicating its ro

Ant workers that are infected with a tapeworm live much longer than their uninfected nest-mates. Parasitic infections are usually harmful to their hosts, but there are some exceptions. According to the results of a multi-year scientific study, ants of the species
Temnothorax nylanderi show exceptionally high survival rates when infected with a tapeworm. The lifespan of the infected ants is significantly prolonged. According to our observations, such workers have a survival rate similar to that of queens, said Professor Susanne Foitzik of Johannes Gutenberg University Mainz (JGU), leader of the study. Queens of this species can live for up to 20 years, while female workers rarely reach the age of two. Among possible explana
