Alice Catherine Evans
Bacteriology in Milk and Cheese
Alice Evans was intrigued to discover a close similarity between two types of bacteria: Bacillus abortus and Micrococcus Melitensis.
Bacillus abortus causes spontaneous abortions in cows and not thought to transfer to humans.
Micrococcus Melitensis causes a disease in humans that was originally known as Malta fever and later as undulating fever.
- joint and muscle pain
- weight loss
- belly pain
This disease was more common than thought and happened around the globe. Brucellosis was common among people exposed to raw milk. Evans developed chronic brucellosis as a result of her research.
Because of Evans vaccination of cows and pasteurization of milk are now routine. She is also responsible for the dramatic decline in both bovine (cattle) and human diseases.
