Chapter 47, Problem 1CA
Summary Introduction
To analyze:
The identification of species of the bacterium.
Role of artificial hip in the growth of this bacterium.
Introduction:
In the condition of the patient given, an 89-year-old woman who has cleaned her tooth a month back is affected with bacteremia. Bacteremia is the presence of bacteria in the bloodstream.

EXPLAIN THE PURPOSE OF THE METHYL RED AND VOGES-PROSKAUER TESTS IN DETERMINING THE IDENTITY OF GRAM NEGATIVE ORGANISMS IN THE FAMILY ENTEROBACTERIACEAE. INCLUDE IN YOUR ANSWER WHY METHYL RED IS USED RATHER THAN PHENOL RED. WHAT ORGANISM IN THE FAMILY IS USED AS A CONTROL WHEN RUNNING THE METHYL TEST. IF THE METHYL RED TEST IS NEGATIVE, EXPLAIN WHY THE VOGES-PROSKAUER TEST IS RUN AND INCLUDE WHAT COLOR CHANGE INDICATES A POSITIVE TEST. ACCOUNT FOR THE COLOR DIFFERENCES IN THE NEGATIVE VOGES-PROSKAURER TESTS. WHAT REAGENTS (COMMON NAME) WERE USED IN THE VOGES -PROSKAUER TEST.
This is a catalase-positive, coagulase-negative, gram-positive coccus isolated from a urine specimen from a 20-year-old female college student. The image shown is a Mueller Hinton plate streaked with a 0.5 MacFarland standardized inoculum and a 5 microgram disk of novobiocin after overnight incubation. What is the identification of the isolate?

Stains of the lung tissue were negative by Gram, methenamine silver, and acid-fast methods, but Dieterle silver stains revealed short bacilli. Lung cultures yielded Gram-negative bacilli, which grew aerobically on buffered charcoal-yeast extract, but not on blood or chocolate agar. The organisms resembled Legionella, but failed to stain with immunofluorescence conjugates for Legionella pneumophila and multiple other species (L minded, L longbeachae, L gormanii, L dumoffi, L bozemanii). The organism was sent to the Centers for Disease Control and Prevention, where it was eventually identified as a new species of Legionella. What is the most probable source of this man's infection?
