For the collection, transport, and examination of fecal specimensSodium acetate-acetic acid-formalin (SAF) is ideally suited for use with helminth eggs and larvae, protozoan trophozoites and cysts, and cocciadian oocysts and microsporidian spores. Slides fixed with SAF may be stained using trichrome or hematoxylin. 10% neutral buffered formalin is an all purpose fixative appropriate for helminth eggs and larvae and for protozoan cysts. The buffering system helps to maintain organism morphology. Fixed specimens may be examined directly or concentrated for recovery of eggs, larvae, and protozoan cysts.C&S media and Cary Blair media facilitate the collection and transport of enteric bacterial pathogens, while maintaining the bacterial population for optimum recovery for up to 96 hours. C&S medium: Agar, sodium thioglycolate, Na2HPO4, calcium chloride, phenol red. Cary Blair medium: Agar, DI water, KH2PO4, NA2HPO4, phenol red, sodium chloride, sodium thioglycolate.
