A thick peptidoglycan is MOST often associated with which of the following types of bacteria?
Gram-positive bacteria retain the primary crystal violet stain that is applied in the Gram stain because of the cross-linking of the thick peptidoglycan layer in their cell walls. Their cell walls contain less lipids than that of a gram-negative bacteria, and this reduces the permeability of their cell wall to...

What is the best conclusion?
The blood glucose value is critical; negative ketones is consistent with type 2 diabetes. An elderly type 2 diabetic patient is at risk for hyperosmolar non-ketotic coma and osmolality should be measured. A measurement of urine glucose would not be useful at this point.

One of the key characteristics to the identification of Nocardia asteroides is its inability to hydrolyze casein, tyrosine or xanthine, as shown in this photograph. Nitrates are reduced to nitrites. Both Nocardia brasiliensis and Actinomadura madurae hydrolyze both casein and tyrosine; Streptomyces griseus hydrolyzes all three of the substrates.

Which one of the following adipocyte products is an important messenger in metabolism, signaling the hypothalamus that there are changes in fat stores?
Leptin signals the hypothalamus that there are changes in fat stores. Resistin increases insulin resistance and enhances adhesion molecules present on endothelial cells. IL-6 responds to tissue injury. IL-6 increases insulin resistance by inhibiting insulin receptor signal transduction in liver cells. It also increases other inflammatory cytokines, interleukin-1 (IL-1) and...
