Title: A middle-aged women presented to the emergency room complaining of cramping and gastrointestinal ... Post by: Sqwill23 on Feb 20, 2018 A middle-aged women presented to the emergency room complaining of cramping and gastrointestinal discomfort. She had recently attended a family reunion the past weekend. The event was a picnic where potato salad, hamburgers, deviled eggs, hot dogs and chips were served. A feces culture was requested resulting in no growth. What would be the next recommended follow-up testing?
a. Serologic testing for IgM and IgG b. No follow-up testing required c. Collect an additional specimen and at-tempt to cultivate on specialized media d. Treat the patient with ampicillin Bacteria described as being coryneform have which of the following morphologic features? a. Squared rods with squared ends arranged in pairs b. Short gram-positive cocci in branching chains c. Resemble and are often referred to as Chinese letters d. Long branching gram-positive bacilli Quality control is set up on urea media. Which two organisms should be used to determine the validity of the media? a. C. ulcerans and C. diphtheria b. C. diphtheria and Streptococcus pneumo-niae c. C. ulcerans and Corynebacterium pseu-dotuberculosis d. C. glucuronolyticum and C. ulcerans A catalase-positive, gram-positive bacillus that is not acid-fast, does not branch, and does not form spores could possibly belong to which group of bacteria? a. Corynebacterium b. Bacillus c. Actinomyces d. Mycobacterium Bactericidal tests should be performed: a. for severe and life-threatening infections. b. for every clinically significant organism isolated from a clinical specimen. c. for evaluation of antimicrobial agents usually considered bacteriostatic. d. for bacteria isolated from wounds, wheth-er or not they are clinically significant.

A follow-up specimen is highly likely to not result in the isolation of a potential pathogen without an increase or change in symptoms at this time. The patient's condition may resolve inde-pendently if the isolate is a pathogen such as Staphylococcus aureus that may have been trans-mitted in the potato salad or deviled eggs. The other potential sources of infection include the hamburger, Escherichia coli or the hot dogs for L. monocytogenes. E. coli is not indicated unless there is evidence of undercooked hamburger. - - - - - - - - - - - - C Most of the genera in this chapter (except Listeria, Rothia, and Oerskovia) are classified as co-ryneform bacteria, that is, they are gram-positive and have short or slightly curved rods with rounded ends; some have rudimentary branching. Cells are arranged singly in palisades of pa-rallel cells or in pairs that remain connected after cell division to form V or L shapes. Groups of these morphologic characteristics observed together resemble, and are often referred to as, Chi-nese letters. - - - - - - - - - - - - A The only organisms that are positive and negative for urea are C. ulcerans and C. diphtheria. The other organisms are either both positive or both negative for urea. - - - - - - - - - - - - A The genera described in this chapter, including Corynebacterium species, are all catalase-positive, gram-positive rods. They are not acid-fast, most do not branch, and they do not form spores. - - - - - - - - - - - - A Bactericidal tests are not necessary as part of routine susceptibility testing and, because of their complexity and difficulty, should be used only in cases of severe and life-threatening infections.
