Infection with pan-resistant klebsiella pneumoniae: a report of 2 cases and a brief. Klebsiella = bacteria that normally lives in your gut but can cause dramatic lung problems sometimes. Talk about resistance in 3 diferent cases: malaria: resistance in parasite and vector, antibiotics: resistance in bacterial pathogen. Antibiotics only used to treat bacterial infections: hiv: resistance in a virus (viral pathogen) (1) malaria [parasite and vector. Disease caused by parasite of genus plasmodium. Symptoms: fever, chills, anemia (due to loss of red blood cells) Cartoon: red blood cell bursting out parasites. Plasmodium is mosquito transmitted: parasites going to infect new red blood cells in which they replicate and eventually burst that blood cell (then get anemia) Lots of cases of malaria: half a million deaths a year: mostly in sub-saharan africa, mostly kids dying. Malaria parasite spends some time in mosquitoes vector and some in human host.
