The microbiology lab was able to isolate one of the organisms from Tara’s blood. Using a Kirby-Bauer test (disk diffusion assay)

Lynna [10]

Answer:

Amoxicillin and Tetracycline

Explanation:

Kirby-Bauer test is used to determine the susceptibility of a bacteria to an antibiotic. The target bacteria is grown on an agar plate. Antibiotic wafers are places on these plates. After some time, the plate is checked. Zone of inhibition (ZOI) is the area around the wafer where no bacteria survived. A reference table is checked for determining the susceptibility of the bacteria to a particular antibiotic. If the value of ZOI is smaller than the value required for susceptibility (S), it means that the bacteria is resistant to that antibiotic.

From the given data, ZOI for Amoxicillin is 25 and S value is ≥29 so the organism in question is resistant to Amoxicillin and Amoxicillin is not an appropriate choice for treatment. Similarly, ZOI for Tetracycline is 18 and S value is ≥19 hence it is not the appropriate choice for treatment.

gayaneshka [121]

Answer:

The intercalated cells in the distal convoluted tubule of a nephron can cause and increase or decrease in body pH.

Explanation:

The renal collecting duct is the nephron segment where the final urine content of acid equivalents and inorganic ions are determined.

Two types of cells regulate the acid-base and volume homeostasis.

Intercalated cells, which express acid-base transporters and vacuolar H+-ATPase, maintain an apropriate acid-base balance and principal cells that express the epithelial sodium channel ENaC and aquaporin 2, regulate electrolyte reabsorption.

Filtered bicarbonate is predominantly reabsorbed from the proximal convoluted tubule about 80% and the remaining bicarbonate is reabsorbed from the thick ascending limb of the loop of Henle, the distal nephron, specifically the distal convoluted tubule & the connecting tubule, and finally the cortical and both the outer and inner medullary collecting duct.

Intercalated cells are enriched in mitochondria, and express proteins involved in transport of proton equivalents such as vacuolar H+-ATPase, carbonic anhydrase II and bicarbonate transporters. There are two types of intercalated cells Type-A and Type-B.
