Toxins Antiseptic Chemical agents applied to tissue to prevent infection often not as harsh as disinfectants as they must not destroy too much living tissue, Chemotherapy Use of chemical agents to kill or inhibit the growth of microorganisms within living host tissue. The next microbiology book consists of a full-color laboratory manual, which is designed for both non-major and major lab course students taking microbiology at an introductory level. There were several challenges to this theory - Agostini Bassi: diseases were due to microbial infections. These agents do not kill, but they do prevent growth. 10 5'cells ' 5 ' '99.99%' Bacteriostatic. Archea - Prokaryotes Septum formation at midline General Microbiology Notes Lecture notes.
