Here's a pretty decent thread with some pics of different infections:

Not all infections look the same as you can see from the pictures.

What is making you worry? Why would you assume you have an infection?

all of those examples look as if something is wrong. i was wondering if it can be infected and have NO VISIBLE signs. i am questioning a batch i brewed that has funky flavor and i never saw anything out of the ordinary and ALL the bottles have it. (before i get the run down of other ways i can get infections i really just want to know about primaries and if you can be infected and not SEE anything)

Can you describe the funky flavor?

And it is possible that the infection wasn't present in your fermenter and showed up somewhere in your bottling/kegging process. That way you never would have seen it.

Sure - whether or not there an infection produces visible symptoms depends on what kind of critter is the cause.

yes i know this. i am wondering about scratches in the plastic fermenter or the spigot not being clean enough. is it possible to have an infection bad enuf to ruin flavor and it gets missed all the way trough bottling ?

A Brettanomyces pellicle is something to behold as well.

Can you describe the 'funky' flavor that you are experiencing?
