In questo libro abbiamo riportato la caratterizzazione biologica dei batteri simbionti dei nematodi entomopatogeni. I batteri simbionti isolati da ceppi di EPN sono stati identificati come Xenorhabdus stockiae (Steinernema siamkayai) e Photorhabdus luminescens (Heterorhabditis indica). Gli isolati recuperati sono stati valutati per l’attività antibatterica contro vari organismi patogeni; i risultati hanno mostrato un’ampia gamma di attività antimicrobiche contro E. coli, S. aureus, S. typhi e K. pneumonia. Rispetto a X. stockiae, P. luminescens ha mostrato una buona attività antimicrobica, in concentrazione massima contro K. pneumonia e S. aureus. L’analisi FT-IR dell’estratto grezzo di acetato di etile di Xenorhabdus ha mostrato i valori di picco più alti di 2373,33 e 544,93, mentre Photorhabdus ha mostrato la presenza di valori di picco di 2128,00 e 552,80 rispettivamente che indicano lo stretching del gruppo funzionale P-H e degli isocianuri. I risultati ottenuti hanno mostrato la possibilità di ottenere altri nuovi composti con potenziale antimicrobico dai batteri simbionti dei nematodi entomopatogeni che possono essere utilizzati nella formulazione di bioinsetticidi.

  • Viral Replication Complexes
    Viruses are obligate intracellular parasites that need to co-opt a living cell’s machinery for replication. At the heart of the viral replication machinery are the nucleic acid polymerases, which are responsible for efficiently copying the viral genome. This process must often be coordinated with other viral processes, including protein translation and viral packaging. The poly...

    The flaviviruses are composed almost entirely of arthropod-borne viruses, a subset of which are responsible for millions of cases of human disease each year. Among these viruses are dengue virus—a scourge throughout the tropical regions of Asia and the Americas; yellow fever virus—the “original” hemorrhagic fever virus; and the recently emerged Zika virus. While the flaviviruse...

    This edited book brings together research reports on the asymmetry of brain function in various species, including humans, dogs, birds, lizards and bees. As shown in a wide range of species, and, as we now know, not solely in humans, the left and right sides of the brain process information in different ways and control different responses or patterns of behaviour. Since this d...

    Joëlle Roche
    The epithelial-to-mesenchymal transition (EMT) is a highly dynamic process with multiple transitional states, by which epithelial cells can convert into a mesenchymal phenotype. This process involves loss of cellular adhesion and cellular polarity, and an improvement in migratory and invasive properties. It occurs during normal embryonic development, tissue regeneration, organ ...
