Document Summary
H1n1 outbreak in alberta, christmas 2013 resulted in 10 deaths. Ebola virus outbreak, 2014: guinea, sierra leone, liberia. Zika virus links to microcephaly in newborns via placental transmission. Measles virus, paramyxoviridae: transmission: aerosols, major problem in south america & africa, symptoms: rash, fever, highly contagious (especially in the unvaccinated) Viruses are everywhere (exogenous: all infected by a herpes virus (for life, calicivirus infection of whale (rashes, gastroenteritis) In our genetic code: 10% of dna is from endogenous retroviruses (viral remnants) Most are abstracted by barrier, innate immunity, and adaptive immunity. Polydnaviruses w/ wasps & caterpillars (symbiogenic relationship: wasps lays eggs inside living insect larva along w/ polydnavirus, polydnavirus genes suppress the larva"s innate immune repose that would normally kill the egg. Curvularia thermal tolerance virus (cthtv) which helps a fungus: fungus curvularia protuberant permits plant survival, but cant grow at >50 c, virus gives fungal thermotolerance, allowing for the fungus to infect the plant.
