Medical parasitology (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) The study of invertebrate animals capable of causing disease. Often considered tropical but now have global impact. Organisms that derive sustenance from and injure their hosts. Separated into 2 main groups: protozoa: unicellular, classified according to size and means of locomotion, about 45,000 species, metazoa: multicellular. Protoplasm is enclosed by a cell membrane and ceontains organelles. All animals can be infected w/ one or more species (cid:1) 7 protozoan phyla (of 13 total) of medical importance: 4 phyla of flagellates, amoebozoa- movement via pseudopodia, ciliophora- ciliates, sporozoa- includes apicomplexa and coccidia, microspora- inject spores into host cells; fungal (cid:1) All humans have protozoa living in or on their body at some point. Some are commensals: ex: entamoeba gingivalis commonly found in the mout. Some cause mild to life threatening diseases.
