Possible Virus/Bacterial Infection?

[Tim P.]

The following pictures were taken of my first phal that i got and stayed alive... it is almost one year old now in my house. I am kindof worried about it becuase it is developing yellow spots on the bottom two leaves and some different spots that may be from puncture wounds on the newest leaf. This poor orchid figured that it would be fun to fall off of its shelf. Is this a bacterial infection or a viral infection or is it just under stress or... idk what else... it was recently repotted and none of these symptoms showed up until a while ago. Thank you guys again for your help... im just worried for this orchid becuase it is the first one that i have grown successfully and am attached to it

all the other leaves except the bottom two seem fine...

the attached picture is the bottom leaf... i cannot seem to get another picture to load right now so i guess one is better than none
