Assigned reading Lengeler et al. (1999) Chapter 1, p. 1-17 Bacteriology………..
Clostridium difficile Canadian Medical Association Journal www.cmaj.ca July 6; August 31, 2004 http://www.cmaj.ca/cgi/reprint/171/1/27 http://www.cmaj.ca/cgi/reprint/171/5/466
Microbial Physiology Conflicting character of micro-organisms Cause disease –Destroy useful products Foods Computer chips Jet fuel –Alter ecosystems Kill/control detrimental micro-organisms
Microbial Physiology Conflicting character of micro-organisms Food production Solve problems –Environment: bioremediation –Agriculture: GMF –Medicine: recombinant vaccines Exploit potential of beneficial m-o
3 Questions How do micro-organisms find / transport nutrients? How do micro-organisms convert nutrients into cellular components? How do micro-ogranisms respond to changes in type / availability of nutrients?
Bacterial cell architecture Major structural and functional components of micro-organisms Light microscopy of bacteria –Rod shape –Coccus shape –Spiral shape
