Brucellosis Having made the discovery that the bacteria were certainly nearly identical and perhaps totally so, Evans then wondered why Malta fever was not widely diagnosed or reported in the United States. She began to wonder whether many cases of vaguely defined febrile illnesses were in fact caused by the drinking of raw (unpasteurized) milk. During the 1920s, this hypothesis was vindicated as it was found that although raw milk causes no problems most of the time, there is greater risk and unpredictability about when and where the foodborne illness exceptions may strike. Such illnesses ranged from undiagnosed and untreated GI
Conflict procedure and contingent electric foot shocks." In order to operate the experiment, researchers build anxiety by electrical shocks on rats gradually through a training in serval week. This process was what researchers called Conflict Procedure. Conflict procedure The conflict procedure is an experiment often used in scientific research to quantify anxiety levels by measuring changes in punished/unpunished responding. It is often used to screen drugs for their potential to inhibit anxiety (anxiolytic potential). Some researchers from France have conducted an experiment on "Effects of Chronic Antidepressants in an Operant Conflict Procedure of Anxiety in the rat (1998)", "the aim of their
