Expert Solution

Step 1

Gram-negative bacteria cause infections including bloodstream infection, pneumonia, surgical site infection or wound, and meningitis. These are resistant to various drugs and are resistant to more antibiotics available. These have inbuilt antibiotics to find new ways to become resistant and pass their genetic material. The E.coli, Acinetobacter, and Klebsiella are gram-negative bacteria.

Step 2

Answer - Pseudomonas aeruginosa is the common non-fermentative bacteria associated with clinical infection mainly nosocomial infections. Acenetobacter baumanni complex, Stenotrophomonas maltophilia, and Burkholderia spp are generally isolated from the hospital patients mainly from respiratory specimens. These are not always clinically significant.

The non-fermenter isolation from single blood culture is an indication that the organism is acting as a colonizer or contaminant instead a relevant pathogen. The presence of non-fermenter on a gram-stain from a sterile site shows only organisms isolated and is in high number. The clinical significance of this organism is considered.

Coding for Laboratory Services Laboratory testing is one of the most common types of ancillary services that providers will request to be performed on a patient. There are many reasons why laboratory testing may be completed. Consider a time when you or a loved one had lab testing. Perhaps use these tests as your example when sharing your code selections during this discussion. Apply your knowledge of what you have learned in this CPT section. Include the following aspects in...

"The most widely used stain in microbiology is the Gram stain. Based on differences in the structure of the bacterial cell wall, the Gram stain divides bacteria into two major groups: Gram-positive and Gram-negative. Gram-positive cells have a thick layer of peptidoglycan, a polymer made of amino acids and sugars, in the cell wall. Crystal violet binds to peptidoglycan, rendering the cell purple. Gram-negative cells also have peptidoglycan and initially also stain purple. Since the peptidoglycan layer is much thinner,...

You have just isolated a new strain of Gram negative bacteria that can catabolize the sugar aspartame. Genome comparisons to all other strains don't provide any insight into the identity of this pathway. 1) Describe an experiment to identify the pathway coding for aspartame catabolism 2) Describe an experiment to move this pathway into E. coli 3) Given what we learned in class, describe how this pathway is likely positively regulated and where promoter sequence would be 4) Describe an...

Describe the color of both gram-positive and gram-negative cells after each of the four steps in the gram staining method (not including rinsing with water). Why does alcohol easily decolonize gram negative bacteria, but not those that are gram-negative? How are the results of a gram stain important in prescribing a treatment for a bacterial information?
