The organism that is commonly associated with the production of cold agglutinins is:

Terminal spores are commonly seen in gram stains of what organism?

A thin anaerobic gram negative bacillus with tapered ends was isolated from an empyema and was found to be indole positive, lipase negative, and inhibited by 20% bile.  Colonies were described as “speckled” or resembling “ground glass” and fluoresced weakly when exposed to UV light.  The most probable identification of this isolate would be:

Although the culture of organisms in the family Spirochaetaceae is not generally recommended, Kelly’s medium has been useful in cultivating species of:

Rickettsia and Ehrlichia species all:

The primary stain in the Ziehl-Neesen method of staining is forced into the lipid cell wall with:

The image below shows the results of O-F media. The organism is considered to be

A first morning sputum is received for culture of mycobacteria. It is digested and concentrated by the NALC method. Two Lowenstein Jensen slants are incubated in the dark at 35 degrees C with 5-10% CO2. the smears reveal acid fast bacilli and after 7 days, no growth appears on the slants. The best explanation is:

A Gram-negative bacillus isolated from a stool specimen which appears curved on the Gram stain and grows best at 42 degrees C in reduced oxygen and increased carbon dioxide is most likely:

In ______, amplification and product detection occur in the same reaction vessel, and target nucleic acid is detected by fluorescent probes as the hybrids form.
