Well there is your problem: you have that syndrome formed wrong. For a comparison, here is one that turns things into a dwarf:
[SYN_NAME:Dwarf]
[SYN_CONTACT][SYN_INHALED][SYN_INJECTED]
[CE_BODY_TRANSFORMATION:PROB:100:START:1:END:500000]
[CE:CREATURE:DWARF:MALE]
You don't even have the target CE:CREATURE, so it just goes to the default toad.
So if you want it to work the way I think you want it to work, you would have to do something like:
[SYN_NAME:AssimilateM]
[SYN_CONTACT][SYN_INHALED][SYN_INJECTED]
[SYN_IMMUNE_CREATURE:DWARF:FEMALE]
[CE_BODY_TRANSFORMATION:PROB:100:START:1:END:500000]
[CE:CREATURE:BORG:MALE]
And
[SYN_NAME:AssimilateF]
[SYN_CONTACT][SYN_INHALED][SYN_INJECTED]
[SYN_IMMUNE_CREATURE:DWARF:MALE]
[CE_BODY_TRANSFORMATION:PROB:100:START:1:END:500000]
[CE:CREATURE:BORG:FEMALE]
That will temporarily turn the dwarf of the proper gender into a borg. If you JUST want it to work on dwarves/humanoids, you will have to change it a little bit, same thing if you want it to be permanent. At the moment, it would turn anything from cats to alligators into borg...which means you should probably do:
[SYN_NAME:AssimilateM]
[SYN_CONTACT][SYN_INHALED][SYN_INJECTED]
[SYN_AFFECTED_CREATURE:DWARF:MALE]
[CE_BODY_TRANSFORMATION:PROB:100:START:1:END:500000]
[CE:CREATURE:BORG:MALE]
And
[SYN_NAME:AssimilateF]
[SYN_CONTACT][SYN_INHALED][SYN_INJECTED]
[SYN_AFFECTED_CREATURE:DWARF:FEMALE]
[CE_BODY_TRANSFORMATION:PROB:100:START:1:END:500000]
[CE:CREATURE:BORG:FEMALE]
Which will only affect dwarves of the correct gender.
