Given the following reactions, chose the best answer to identify the organism: MAC = Pink Colonies PAD = Negative Urea = Positive Indole = Positive ONPG = Yellow Lysine = Positive Motility = Negative TSI = Acid/Acid Ornithine = Negative VP = Positive

The Enterobacteriaceae have the following common characteristics:

An otherwise healthy 69-year-old male presents to his physician with fever and shortness of breath. Chest x-ray reveals a right lower lobe pneumonia. Gram stain of an expectorated sputum specimen show many neutrophils, few squamous epithelial cells, rare Gram-positive cocci in chains, and many plump Gram-negative diplococci. Sputum culture reveals few small, round alpha hemolytic colonies and many medium, tan gamma hemolytic colonies on BAP. The growth on CHOC plate is similar to BAP. MAC has no growth. When a tan colony is touched with an inoculating loop it slides on the plate like a hockey puck. Oxidase and butyrate test on the tan colonies are both positive. What organisms is causing this man’s pneumonia?

Given the following reactions, chose the best answer to identify the organism: Urea = Positive ONPG = Positive TSI = yellow/yellow Ornithine = Positive                MAC = clear colonies Indole = variable       MR = Positive             PAD = Negative                      DNase = Negative Motility = Negative               Nitrate = Positive                 Gram negative bacilli

An enteric organism is colorless on MAC and yellow/black on TSI. Completely interpret these reactions:

A foot ulcer from a diabetic patient grew oxidase negative bacilli that were lactose negative on MacConkey.  The following biochemical tests were performed:   Phenylalanine deaminase: Negative Citrate: Positive SIM: 0, 0, +  MR/VP: 0/+ Lysine decarboxylase: Negative Ornithine decarboxylase: Negative DNase: Negative ONPG: Positive Arabinose: Positive The organism should be identified as:

Modified Thayer-Martin agar is prepared with hemoglobin base, supplemented with enrichments and:

The urine culture from a 4 year-old girl yields >100,000 organisms/ mL large grey mucoid colonies on BAP and large pink mucoid colonies on MAC. Based on the following biochemical tests, what is the most likely cause of her UTI? Indole = neg Motility = neg Citrate = peacock blue MR / VP = neg / pos Urea = hot pink  Oxidase = neg DNAse = neg TSI = A/A

A pink colony is isolated on MAC from a clean catch urine culture with a colony count >100,000 / ml.  The following biochemical reactions were recorded:   TSI: acid / acid with gas, no hydrogen sulfide Lysine decarb: Positive Indole: Positive Urea: Negative Citrate: Negative Motility: Positive   The most likely identification of the organism is:

Assume you are given a dictionary course_dict with ACT101, FIN202, MKT300, MIS310 and MIS340 courses and the corresponding number of credits 4, 3, 3, 3 and 2. Given a blank list lst, what would be the result from running this code? for key in course_dict:  if course_dict == 3:    lst.append(course_dict)print(lst)
