The production of long, tapered phialides is one of the key identifying features of Trichoderma species. In contrast, Penicillium species, produce phialides with blunt ends.
The phialides of Beauveria species are geniculate, forming a zig-zag pattern.
The arrows in the image on the right point to single, long, tapered phialides that extend laterally from either side of the hyphae. This is an identifying feature of which of the fungi listed below?
The beta hemoglobin chain loci are found on which chromosome?
What two glycoproteins are expressed on the surface of influenza A viruses and are used for subtyping of the viruses?
Following an accidental needlestick, the person should be tested for all of the following except:
Hybridization is a technique used to determine presence of target DNA or RNA by adding a synthetic strand that binds by complementary base pairing to the target.
Microbiology
In molecular diagnostic testing, hybridization employs complementary base pair binding of a synthetic strand to DNA or RNA.
AABB Standards do not require a DAT, autologous control, or a minor crossmatch for pretransfusion testing.
Essential components of compatibility testing include all of the following except :
In excess triglycerides, the triglycerides reduce the amount of cholesterol in LDL particles producing small dense LDL molecules. Because of size and density, these molecules more easily enter damaged endothelium and vessel walls and are more easily incorporated as plaque is formed.
Which statement best describes small dense LDL particles that can occur in atherogenic dyslipidemia?
Provide the equivalent measurement for one gallon.
Question options:
In this case, with the pre-incubation aPTT mixing study result "corrected" and the post-incubation aPTT mixing study result "not corrected", a coagulation inhibitor should be suspected. Both anti-factor VIII and lupus anticoagulant have been known to be slow-acting and can exhibit this result pattern. If a factor deficiency was present, we should not see a post-incubation prolongation.
Hematology
What may cause the following mixing studies results?
Initial aPTT = 133 seconds
1:1 Mix aPTT pre-incubation = 33 seconds
1:1 Mix aPTT post-incubation = 124 seconds
The Westgard multi-rule 22S describes the scenario where two consecutive data points fall outside +2SD or -2SD. If this occurs, then the run must be rejected. This situation is most likely caused by a systematic error.
Which of the following describes the Westgard multi-rule 22S?
Confirmed cases of H1N1 virus have been reported more often in children and younger adults than in any other age group.
Micro
The age groups that have been most affected by the H1N1 virus are children and younger adults.
The best course of action when entering an isolation room is:
A zone of inhibition is the area around an antibiotic-infused paper disk that does not show any bacterial growth. The antibiotic impregnated on the disk will diffuse into the agar in the area surrounding the disk. If the bacteria are sensitive to the antibiotic, they cannot grow near the disk. The size of the zone is proportional to how sensitive the organism is. If the organism is resistant to the antibiotic, it will grow very closely to the disk.
The size of the zone of suppressed growth on a sensitivity plate using sensitivity disks is referred to as the zone of:
A patient has a WBC count of 4,000/mm3, a platelet estimation with 3 bizarre platelets/oil immersion field, hemoglobin, hematocrit, red cell count and indice values are within normal limits. Blue-staining inclusions are seen in the cytoplasm of many neutrophils. These inclusions fit the description of:
The FTA-ABS is used to confirm that a positive non-treponemal test like RPR is not the result of a biological false positive, which occur in about 1 to 10 percent of the population.
A positive RPR test and a negative FTA-ABS test is most likely the result of:
