Growth and enterotoxin production of Bacillus cereus in cow, goat, and sheep milk

Popis výsledku v původním jazyce

The aim of this study was to compare Bacillus cereus growth rates and diarrhoeal enterotoxin production in raw and pasteurized goat, sheep, and cow milk in terms of storage conditions. Milk samples were inoculated with B. cereus (CCM 2010), which produces diarrhoeal enterotoxins. Enterotoxin production was tested by ELISA (Enzyme-Linked Immunosorbent Assay), and the count of B. cereus was determined by plate method. With raw cow milk, B. cereus growth and enterotoxin production can be completely suppressed; in raw goat and sheep milk, enterotoxin was produced at 22 oC. In cow, goat, and sheep pasteurized milk, the B. cereus count increased under all storage conditions, with more rapid growth being observed at 15 oC (sheep milk) and 22 oC (cow and goatmilk). Enterotoxin presence was detected at 15 oC and 22 oC, and with pasteurized cow milk also at 8 oC. Our model experiments have determined that B. cereus multiplication and subsequent enterotoxin production depend on storage temperatu
