Four formal rounds of Trans-Pacific Partnership Agreement (TPPA) negotiations took place in 2010. They involved over 200 officials from Australia, the United States, New Zealand, Chile, Singapore, Brunei, Peru, Vietnam and Malaysia. Future negotiations officially are set to include three issues with public health and medicines policy implications for Australia and our region: ways to approach regulatory coherence and transparency; how to benefit multinational and small-medium enterprises; and multilateral investor-state dispute settlement. US-based multinational pharmaceutical companies are lobbying for TPPA provisions like those in the Australia-US Free Trade Agreement, which reduce government cost-effectiveness regulatory control of pharmaceuticals, threatening equitable access to medicines. They also advocate increased TPPA intellectual monopoly privilege protection, which will further limit the development of Australian generic medicine enterprises and restrict patient access to cheap, bioequivalent prescription drugs. Of particular concern is that proposed TPPA multilateral investor-state dispute settlement procedures would allow US corporations (as well as those of other TPPA nations) to obtain damages against Australian governments through international arbitral proceedings if their investments are impeded by Australian public health and environment protection legislation.
Costelytra zealandica (Coleoptera: Scarabeidae) is a univoltine endemic species that has colonised and become a major pest of introduced clover and ryegrass pastures that form about half of the land area of New Zealand. Female beetles were previously shown to use phenol as their sex pheromone produced by symbiotic bacteria in the accessory or colleterial gland. In this study, production of phenol was confirmed from the female beetles, while bacteria were isolated from the gland and tested for attractiveness towards grass grub males in traps in the field. The phenol-producing bacterial taxon was identified by partial sequencing of the 16SrRNA gene, as Morganella morganii. We then tested the hypothesis that the phenol sex pheromone is biosynthesized from the amino acid tyrosine by the bacteria. This was shown to be correct, by addition of isotopically labelled tyrosine ((13)C) to the bacterial broth, followed by detection of the labelled phenol by SPME-GCMS. Elucidation of this pathway provides specific evidence how the phenol is produced as an insect sex pheromone by a mutualistic bacteria.
