A patient was seropositive for HIV experieced abdominal pain, fatigue, and low-grade fever for 2 weeks. A chest x-ray showed lung infultrates. Gram and acid fast stains were negative. Viral culture showed a large enveloped polyhedral virus with double stranded DNA.

Im not sure of the disease and which virus caused it. Why did they perform the viral culture only after the Gram and acid fast stain results were obtained?

what is the simple interwewst whewn prwincipal is 4,500 forw 3 months at 67.50 %

what disease causes a large, enveloped polyhedral virus with a double-stranded DNA

The patient's symptoms and chest x-ray findings indicate a potential infectious cause for their symptoms. To determine the specific causative agent, the healthcare team performs several tests, including Gram and acid-fast stains.

Gram staining is a common technique used to classify bacteria into different groups based on the structure of their cell wall. Acid-fast staining, on the other hand, is frequently used to identify acid-fast bacteria, such as Mycobacterium tuberculosis, which causes tuberculosis.

In this case, the Gram and acid-fast stains came back negative, suggesting that the abdominal pain, fatigue, and lung infiltrates are unlikely to be caused by bacteria or acid-fast bacteria. As a result, the healthcare team decided to perform a viral culture to identify if a virus is responsible for the patient's symptoms.

Viral culture involves growing viruses in a laboratory setting to determine their identity and characteristics. By analyzing the virus from the patient's sample, the healthcare team can identify specific viral strains and determine the most appropriate treatment.

Now, moving on to the second part of your question:

To calculate simple interest, you need to know the principal amount, the time period, and the interest rate.

In this case, the principal is $4,500, the time period is 3 months, and the interest rate is 67.50%.

To calculate the interest, you can use the formula:

Interest = (Principal * Rate * Time) / 100

Plugging in the given values:

Interest = (4500 * 67.50 * 3) / 100

Simplifying the expression:

Interest = (450000 / 100)

Interest = $1,012.50

Therefore, the simple interest when the principal is $4,500 for 3 months at an interest rate of 67.50% is $1,012.50.
