1) True. All members of the bacterial family Enterobacteriaceae have an E.coli like electron transport chain, which means they are oxidase negative. The members are catalase positive.
2) The Synder test is intended to determine an individual's susceptibility to dental caries (cavities). The pH of the medium has been adjusted to 4.8 and it includes a >1% concentration of agar.
SNA's have an indicator of pH and a substrate of bromcresol green.
3) If a urea agar slant (with pH buffer) was inoculated and incubated for 24 hours at body temperature and a pink color is observed in the medium, the organism can be concluded to hydrolyze urea to ammonia end products and a probable urinary tract pathogen.

Question 1 (1 point) An unknown organism was inoculated into a phenol red tub and produce a yellow coloration. The same organism was inoculated into a purple broth tube resulted in growth after the incubation period. Green slant tubes were also inoculated and resulted in a blue coloration. However, this organism was negative for motility within a SIM tube. Which of the following is the unknown species? Salmonella typhimurium Shigella sonnei Enterobacter aerogenes Klebsiella pneumoniae Escherchia coli O Proteus mirabilis...
