The presence of hyaline, septate hyphae, and a young conidiophore with a foot cell and a swollen vesicle in a fungus culture are excellent clues indicative of Aspergillus. Aspergillus has the ability to infect primarily immunocompromised hosts, and causes pneumonia and/or disseminates to other organs. Clinical specimens should be inoculated onto primary isolation media, such as Sabouraud's dextrose agar. Aspergillus spp. are fast growing and can be white, yellow, yellow-brown, brown to black or green in color.
The presence of hyaline, septate hyphae, and a young conidiophore with a foot cell and a swollen vesicle in a fungus culture are excellent clues indicative of:
A key laboratory characteristic by which Mycobacterium bovis can be separated from Mycobacterium tuberculosis is:
A beam splitter is employed in a dual beam spectrophotometer.
Which of the following is not a component of a basic single beam spectrophotometer:
High-sensitivity C-reactive protein (hs-CRP) is used as an aid in the diagnosis and treatment of cardiovascular disease (CVD). At low levels, it can detect those at risk for cardiac heart disease. At high levels in those with no history of heart disease, it indicates a high risk for acute myocardial infarction (AMI), stroke, or peripheral vascular disease. For patients with acute coronary syndrome (ACS) or stable coronary disease, hs-CRP is used to predict future coronary events.
Ranges of hs-CRP in prediction of risk for CVD are:
<1.0 mg/L Low CVD risk
1.0-3.0 mg/L Average risk for CVD
>3.0 mg/L High risk for future CVD
If results are >10.0 mg/L, the patient should be evaluated for an acute inflammatory condition.
Chemistry
A high-sensitivity C-reactive protein (hs-CRP) test result of 5 mg/L (normal = < 1 mg/L) may indicate which of the following?
Match the viruses below with their associated conditions.
1. Herpesvirus
2. Papovavirus
3. Rhinovirus
4. Rotavirus
Bacitracin susceptibility is a presumptive test for the identification of Lancefield group A Streptococcus.
Which of the following is a presumptive test for the identification of Lancefield group A Streptococcus:
The end of the initial phase of HH treatment is considered when the serum ferritin decreases to between 20 and 50 ng/mL.
What is a typical finding for determining the endpoint for the initial or iron-depletion phase of treatment for hereditary hemochromatosis (HH)?
