October 2015 ParaBoss News

From the Editor

Summer is certainly on the way. Temperatures are up and in many regions across the country rainfall is down.

As users of this site, we all acknowledge that parasites and research into their control is of paramount importance. It was therefore pleasing to see the 2015 Nobel Prize for Physiology or Medicine awarded for the development avermectin (the parent of ivermectin) and artemisinin, drugs that are now instrumental in the control of roundworm diseases and malarial blood parasites of humans.

The precursors of these drugs were sourced from the natural environment: Avermectin from fungi in soil samples and Artemisinin from the wormwood bush, Artemisia annuanot A. absinthium typically grown in Australia. The impetus to develop these drugs was to better control resistant parasites and to delay further drug failure (see page 6). And these drugs are best used in combination with other drugs and non-drug strategies. Now that sounds like a WormBoss message!
