title: Diversity and biosynthetic potential of culturable microbes associated with toxic marine animals

authors: Chau, Rocky

subjects: tetrodotoxin

abstract: Tetrodotoxin (TTX) is a neurotoxin that has been reported from taxonomically diverse organisms across 14 different phyla. The biogenic origin of tetrodotoxin is still disputed, however, TTX biosynthesis by host-associated bacteria has been reported. An investigation into the culturable microbial populations from the TTX-associated blue-ringed octopus Hapalochlaena sp. and sea slug Pleurobranchaea maculata revealed a surprisingly high microbial diversity. Although TTX was not detected among the cultured isolates, PCR screening identifiedsome natural product biosynthesis genes putatively involved in its assembly. This study is the first to report on the microbial diversity of culturable communities from H. maculosa and P. maculata and common natural product biosynthesis genes from their microbiota. We also reassess the production of TTX reported from three bacterial strains isolated from the TTX-containing gastropod Nassarius semiplicatus.

title: To act or not to act? That is the question!

authors: Bruce Ferguson, Pip

abstract: The year was 2003. I was a new Research Manager working in a Māori tertiary institution that had a history of inequitable treatment by government, through not receiving establishment funding that had gone unproblematically to non-Māori institutions. Repeating a common pattern in New Zealand, our government had decided to implement a research funding scheme, to be measured at the level of the individual academic. My institution’s decision to participate in the PBRF was not without its difficulties, and it is here that the ethics of participation become problematic. This chapter is about our ability to articulate our values, to show how we work these out in our practice, and how we are accountable to ourselves and others for that practice. Would I, with the benefit of hindsight, have encouraged my institution to enter the PBRF again?
