Jim,
My lab routined encountered mold contamination in our heart cell cultures about every other Spring, like clockwork. It would take months to get the incubators sterile again and that meant months of potential research down the drain. Bacterial contaminants were generally just an indication of sloppy sterile technique. Fungus and mold represented a bigger problem.
Anyway, if there was something we couldn't identify, all we had to do is send a sample down the hall or across the building. This was one advantage to being part of a large Medical Center.
Anyway. the lab diagnostic that I got back from my vet indicated fungal growth contamination and that's it....Duh. No ID. I learned that my vet; after asking her for a culture and identification of the "fungus"; put my live sample in formalin before sending it out. Formulin is a fixative; thus killing viable samples. Can you sense my frustration here??
Anyway, I have since contacted an expert in fungal identification in New Zealand. I still have dead sample that can perhaps be identified through histological methods. If I find anything else out, I will post it.
