A gram-negative rod isolated from a burn patient produced a bluish green pigment and the following test results: Characteristic fruity odor TSI: alkaline/alkaline Motility: positive Oxidase: positive Oxidative/Fermentation Glucose: oxidative utilization only The MOST probable genus of this isolate is:

Hektoen-enteric (HE) and xylose lysine desoxycholate (XLD) agars are:

Leptospirosis is a zoonotic disease in humans and is primarily associated with occupational exposure.  Which of the following describes the etiologic agent?

An organism isolated from a stool culture grew well on MAC as a clear, wet-appearing colony. It was oxidase and indole positive and produced acid in the butt of the TSI but not on the slant, and was O/129 resistant. Based on these results, the organism is most likely:

Which of the following is a fermentative, gram negative rod that is categorized as a potential biothreat agent?

Which of the following organisms, if isolated from a stool sample, is always considered a pathogen?

Which gram negative anaerobic bacteria is highly resistant to antibiotics and bile?

A stool specimen is submitted for culture from a patient with gastroenteritis, nausea and vomiting. A gram-negative rod grew on TCBS agar as a large green colony type and was clear on MacConkey agar. Additional characteristics include: TSIA                                                          Alk/Acid H2S                                                            negative VP                                                             negative oxidase                                                     positive nutrient broth with 3% NaCl:                     growth nutrient broth with 10% NaCl:                   no growth catalase                                                    positive nitrate                                                        positive lysine                                                         positive     The most probable identification of this organism is:

An immunosuppressed patient notices sinus tracts that are draining pus.  The pus shows numerous polymorphonuclear cells and branching, beaded, gram-positive rods.  Heaped lobular colonies grow anaerobically and develop a “molar tooth” appearance after several days of incubation.  The most probably agent is:

It is not realistic to implement a(n) _____ strategy when the firm has numerous reactive employees and consumers.
