Flashcards in IX - General Pathology of Infectious Diseases Deck (24)
These agents cause transmissible spongiform encephalopathies.
Infected cells show distinct nuclear and ill-defined cytoplasmic inclusions.
Infected cells show glassy nuclear inclusions, frequently with a surrounding halo.
Infected hepatocytes show diffuse granular (ground-glass) cytoplasm.
Hepatitis B viral infection
Sexually transmitted protozoan that can colonize the vagina and male urethra.
Protozoan acquired either by contact with oocyte-shedding kittens or by consumption of cyst-ridden undercooked meat.
Size of microorganisms for them to be inhaled directly into the alveoli.
These microorganisms grow in contaminated food and releases powerful enterotoxins that cause food poisoning symptoms without any bacterial multiplication in the gut.
Intestinal helminth that cause disease when present in large numbers or cause obstruction of the gut.
Helminth that causes iron deficiency anemia by chronic loss of blood.
Helminth that depletes vitamin B12 giving rise to an illness resembling pernicious anemia.
Placentofetal route as a mode of transmission is also referred to as ________.
The ability of bacteria to cause disease.
Bacterial surface molecules that bind to host cells.
Filamentous proteins on gram negative bacteria which allow exchange of genes between bacteria, and also involved in adherence.
Clostridium perfringens produces this toxin that disrupts plasma membranes resulting in digestion of host tissues and collagen.
Alpha toxin (lecithinase)
Bacterial toxins with the capacity to stimulate large populations of T lymphocytes, functionally resulting in a "cytokine storm".
Examples of antigen presenting cells.
A superantigen secreted by S. aureus which causes inflammation, fever and shock. Found in the vagina of menstruating women.
Toxic shock syndrome toxin (TSST-1)
Collection of neutrophils which gives rise to localized liquefactive necrosis.
High risk agents of bioterrorism which are easily disseminated and has high potential for mortality. An example is smallpox.
A distinctive form of mononuclear inflammation usually evoked by infectious agents that resist eradication, but are capable of stimulating strong T cell mediated immunity. Characterized by epitheloid cells which may fuse to form giant cells.
Agents that are relatively easy to disseminate and produces moderate morbidity and low mortality. An example is E.coli O157:H7 which can cause HUS.
