I don't think so. What benefits could we have from say Ebola, polioviruses, smallpox, HIV, and many other viruses?
I do agree that some so-called pests are usefull (damn mosquitoes that feed birdsand so on), but I definetely would not generalize too fast. And it would be interesting to measure if the by products of ascaris infestations gives a higher fitness to infested people.
Note that he said organism Patrick... last time i checked Ebola or any other virus are not organisms. Agreed with you though.. not all organisms offer advantages
