All samples were sterile when processed in our laboratory. Your suspicion of contamination in your processing is apparently borne out. The spores in your slide of 59AMr 4821 appear to be fungal. A possible explanation of their presence would be the development of a fugal culture in your sample bottle if time elapsed before the slide was made. Adding a few drops of 10% HgCl2 to the storage bottle will prevent fungal growth. Sorry that we have no positive results to report.
