Exam 4 microbiology UTA Exams Questions With Complete
Solutions
•Patients with septicemia (septic) can lead to shock (life-
threatening decrease in BP) TRUE/FALSE Correct Answers
TRUE
•Primary infections can lead to secondary infection of different
pathogen TRUE/FALSE Correct Answers TRUE
acute disease Correct Answers symptoms develop rapidly but
the disease lasts only a short time (hours, days, week)
--flu
Adhesion Correct Answers 2nd step pathogenesis
capability of pathogenic microbes to attach to the cells of the
body using adhesion factors, and different pathogens use various
mechanisms to adhere to the cells of host tissues.
antigen shift Correct Answers a major change in spike proteins
due to gene reassortment
antigen variation Correct Answers alteration of surface
proteins so that a pathogen is no longer recognized by the host's
immune system.
Antigenic drift Correct Answers •result of point mutations
causing slight changes in spike proteins (H & N)
Asymptomatic/subclinical Correct Answers infections that
lack symptoms but may still have signs of infection
, bacteremia. Correct Answers presence of bacteria in the blood
Causes of disease Correct Answers pathogen
genetics
noninfectious environmental cause
inappropriate immune response
chronic disease Correct Answers a disease that develops
gradually and continues over a long period of time (months,
years, lifetime)
communicable disease Correct Answers disease that is
transmitted from one individual to another through indirect or
direct contact aka contagious
Contagious Correct Answers Able to be passed easily from
one person to another.
Disease Correct Answers Any condition in which normal
structures are damaged or impaired
Endotoxins Correct Answers lipopolysaccharides that triggers
host inflammatory responses; can cause sever fever and
shock ,gram negative
-Endotoxin remains stable at high temperatures, and requires
heating at 121 °C (250 °F) for 45 minutes to inactivate.
-HEAT STABLE
enzyme-linked immunosorbent assay (ELISA) Correct Answers
that uses antibodies to detect the presence of endotoxin.
