Psoriasis for thought

I want to share an experience about my Psoriasis that I feel is a little bit unique. I have had only mostly moderate psoriasis for almost 10 years now, like many of you I manage it best I can through my diet. The interesting thing is that my partner also has had Psoriasis for almost 10 years minus 4 months. It began when I moved jobs and worked with a colleague who had moderate to severe Psoriasis, after being there for a few months I used the common toilet right after them and had a terrible splash back, enough for me to note it. It was then 2 months later I came down with my Psoriasis (dec 2010) and I've had it ever since. My partner 4 months after me then also come down with Psoriasis and has also had it ever since. I realise this may sound somewhat odd but I'm very interested if anyone else can share this sort of experience? The chances that both myself and my partner came down with this disease within 4 months of each other are somewhat ridiculous given neither of us had heard of it before hand and there are no family relations that have it for either of us. I am very interested in peoples thoughts on this as I have been searching for answers but there appears to be little to no research done on this specific area of a possible stool transfer style scenario, I would love to see a discussion around this topic if anyone can relate, as it could potentially help understand P a little better. I'm sure many will disagree with this possibility, if so please link to any study or research that can show this scenario isn't possible and is only coincidence.
