When bacteria flourish and grow in the bloodstream, this is referred to as

Septicemia

Bacteremia

Fungemia

Viremia

Which of the following diseases is caused by a retrovirus?

AIDS

Dengue fever

Ebola

Marburg fever

The two means for spreading plague are

Contaminated food and water

Airborne droplets and a mosquito bite

Rat fleas and airborne droplets

Sexual contact and animal bites

A 50-year-old woman receiving chemotherapy via a subclavian catheter for acute leukemia has the sudden onset of blindness in her right eye. Her total white blood cell (WBC) count is 120/μL. Blood cultures grew budding yeasts that formed hyphae. What is the most likely diagnosis of this case?

Candidemia

Fungemia caused by a filamentous fungus

Bacteremia

Septicemia caused by biofilm forming bacterium

A 35-year-old man complains of night sweats, Fever, chills, and fatigue at varying intervals during the past 2 months. These episodes began while he was traveling in Latin America. When questioned, he says that cheeses, especially the unpasteurized varieties, are some of his favorite foods. On examination, his temperature is 39°C, and his liver and spleen are palpable. His hematocrit is 30%, and his WBC count is 5000. Blood culture grew small gram-negative rods. What is the most probable diagnosis?

Anthrax

Brucellosis

Tularemia

Food poisoning

The CTL (T-cyotoxic) response to HIV infection is quite robust; however, these activated CD8+ T cells have little impact on viral clearance or inhibition of AIDS progression. Which one of the following offers an explanation for this observation?

HIV can directly infect CTL causing their lysis upon viral replication

HIV infection of CTL results in insertion of viral DNA into areas of the host genome critical for cell function, thus, infected CTL are functionally impaired

HIV peptides generated in infected cells do not fit into the grooves of the host cell class II MHC molecules, thereby, inhibiting CTL recognition and killing

High mutability of HIV peptides leads to CTL exhaustion

HIV reverse transcriptase is highly efficient (not error prone) and thus protein mutation is a rare event

Which cells infected by EBV allow full virus replication and which may become transformed by the virus?

Lymph node dendritic cells and T cells, respectively

Monocytes and cells of the oropharynx, respectively

Monocytes and hepatocytes, respectively

Nasopharyngeal epithelial cells and B cells, respectively

T cells and splenic macrophages, respectively

A 21-year-old female presented to the college clinic in January with sore throat, cough, fever and wheezing chest. She is treated for mild pneumonia as an outpatient. Following completion of a course of antibiotics, her initial symptoms resolved but she now complains of persistent fatigue and occasional pain in the extremities and occasional bluish discoloration of her finger tips when her hands are cold. Physical exam reveals pallor and tachycardia. Her hematocrit, hemoglobin level, and red cell count reveal anemia. Which of the following is the most appropriate test to order at this point?

Chest X-ray

Direct and indirect Coombs test

Glucose tolerance test

Screen for Anti-VCA and EBNA antibodies

Screen for anti-platelet antibodies
