Proteus species are part of the Enterobacteriaceae family of gram-negative bacilli. Proteus organisms are implicated as serious causes of infections in humans, along with Escherichia, Klebsiella, Enterobacter, and Serratia species.TIs are the most common clinical manifestation of Proteus infections. Proteus infection accounts for 1%-2% of UTIs in healthy women and 5% of hospital-acquired UTIs. Complicated UTIs (ie, those associated with catheterization) have a prevalence of 20%-45%.
Classical conditioning involves pairing a previously neutral stimulus (such as the sound of a bell) with an unconditioned stimulus (the taste of food). This unconditioned stimulus naturally and automatically triggers salivating as a response to the food, which is known as the unconditioned response.
There are three stages of classical conditioning. At each stage the stimuli and responses are given special scientific terms: Stage 1: Before Conditioning: In this stage, the unconditioned stimulus (UCS) produces an unconditioned response (UCR) in an organism.In basic terms, this means that a stimulus in the environment has produced a behavior / response which is unlearned (i.e. unconditioned) and therefore is a natural response which has not been taught.n another example a perfume (UCS) could create a response of happiness or desire (UCR). This stage also involves another stimulus which has no effect on a person and is called the neutral stimulus (NS) . The NS could be a person, object, place, etc.
