Muscle surfaces of pork were inoculated with a mixture of Yersinia enterocolitica and Staphylococcus aureus , and chicken muscle with Campylobacter jejuni or a mixture of Salmonella typhimurium and Staph. aureus . The surface growth at 20°C was followed microscopically. Organisms grew as discrete colonies bound together by a glycocalyx which differed between bacterial species. On prolonged incubation colonies spread peripherally and tended to coalesce, while still retaining their colony structure. Staphlycoccus aureus colonies were very small and remained so. The glycocalyx was considered critical in maintaining the dense populations of bacteria on the meat surfaces.
