Wayson stain
From Infogalactic: the planetary knowledge core
The Wayson stain is a basic fuchsin-methylene blue, ethyl alcohol-phenol microscopic staining procedure. It was originally a modified methylene blue stain used for diagnosing bubonic plague.[1] With this stain, Yersinia pestis appears purple with a characteristic safety-pin appearance,[2] which is due to the presence of a central vacuole.
Wayson stain is used along with the Giemsa and Wright's stains to rapidly detect potential biowarfare attacks[3] It has also been investigated as a possible cheaper and faster way to detect melioidosis.[4] It is a useful alternative to the Gram or Loeffler’s Methylene Blue stains, especially for detecting Yersinia enterocolitica which is often found in contaminated food[5]
