Document Summary

Unit 6: infection general pathology of infectious diseases. The encounter : outcome infection subclinical, clinically apparent disease. Infection of the bloodstream: spread via the bloodstream septicemia, viruses and other intracellular parasites. Varicella-zoster development of neoplasms: body response to viral infections, acute, chronic viral infections. Gram positive cocci bind to host cells by: (two points: gram negative rods and cocci have surface fimbriae (pili), which are filaments composed of repeating subunits. Pili function to: (two points: when an infected mosquito (anopheles spp. ) bites a person, infectious stages of the parasites (sporozoites) are injected (from the mosquito saliva) into the bloodstream, where they undergo asexual reproduction. Complete the following: describe briefly how disease is produced. 309 315**: parasite refers to a plant or animal, which lives upon, or within another living organism, at whose expense it obtains some advantage. By popular usage, however, parasite has come to refer more specifically to protozoan, metazoan (helminths and flukes) and arthropod organisms that cause disease.
