Flashcards in Lecture 20 Deck (20):
blood, blood vessels, and heart. carries oxygen and nutrients to body
lymph, lymph nodes, lymph vessels, lymphoid organs. lots of B and T cells and macrophages. no red blood cells
infection anf inflammation of tissues surrounding heart muscles. begins as an infection elsewhere in the body. bacteria effect pre-existing lesions of the heart.
Symptoms and treatment of endocarditis
symptoms: fever, heart murmur, tissue damage, death. treated with broad spectrum antibiotics, often used as preventative measure
life threatening systemic inflammatory response. caused by bacteria in blood (ex: Klebsiella pneumoniae endotoxin) can lead to sudden decrease if blood pressure. usually begins as nosocomial infection elsewhere in the body
Treatment and prevention of sepsis
treated with bacteriostatic antibiotics (resistance problem) prevention: diagnose and treat local infection
cause by pseudomonas aeruginosa. opportunistic pathogen. produces blue-green pigment on infected burns. grows in dead tissue/wounds. can enter into blood
Treatment and prevention of pseudomonas infections
resistant to a lot of antimicrobial, can be treated with high dose of intravenous antibiotics. prevention: debribe wounds, topical antibiotics. resistant to disinfectants
Yersinia pestis. mainly disease of rodents. transmitted to humans by flea bites. bacterium enters blood and lymph. can survive and grow in phagocytic cells.
Treatment and symptoms of plague
lymph nodes in groin and armpits become enlarged. swellings are called buboes (bubonic plague) untreated with cause death in 50-80% patients
Yersinia pestis spread by respiratory droplets.
Symptoms, treatment and prevention of pneumonic plague
symptoms are pneumonia like, fatal in 3 days. treated with antibiotics, prevented with pest control
infectious mononucleosis, transmitted by direct or indirect contact. virus targets B cells, cytotoxic T cells actively destroy B cells. disease lasts months. weakens immune system
Symptoms of epstein-barr virus
usually infection occurs in early childhood and is asymptomatic. in early adulthood there is fatigue, sore throat, swollen lymph nodes
Latent epstein-barr virus is linked to..
burkitt's lymphoma, multiple sclerosis, hodgkins disease, nasopharyngeal cancer
Ebola hemorrhagic fever
fruit bat is host, used as food to transmit to humans. can be transmitted to humans through direct or indirect contact w/ infected blood, highly contagious
Symptoms of elbow hemorrhagic fever
high fever, vomiting blood, bleeding profusely though external and internal openings. results in organ failure and death in 50% of cases
caused by plasmodium species, carried by mosquitoes and tropical climates. targets red blood cells, new generation of plasmodium released from RBC. 200 mill ppl infected world wide
Symptoms of malaria
anemia, enlarged spleen, characteristic fever cycle temp increase every 2-3 days
