Define the concept of universal precautions. Universal precautions means any and all samples, whether known or unknown, are to betreated as potentially hazardous (or pathogenic) materials. 2. List at least 3 observations a researcher would be sure to note while assessing an unknownmicrobial sample. A lab researcher would be certain to note: 1. Size and shape 2. Any observable motility 3. Gram status (positive or negative) 4. The presence of any

True or False: Growth media is best suited for distinguishing between two similar species of bacteria. False. Growth media is designed to simply support (and not restrict) microbial growth. 2. A researcher is asked to determine which of two vials contains E coli and which contains Salmonella. Knowing both are Gram-Negative while only one of them is capable of fermenting lactose, which type of media would be best suited: BIOD 171 EXAM MODULE 41.
