Most specimen thri We will learn about the proper way to use and handle the microscope. Because microrganisms differ in their response to chemical antimicrobial agents, the choice of disinfectant for a particular purpose is guided in part by the type of microbe present in the. The growth of microorganisms in the body, in nature, or in the laboratory is greatly influenced by temperature pH, moisture content, available nutrients, and the characteristics of other organisms present. See Answer Question: 1. Because these microorganisms contain lipid and are similar in structure and composition to other bacteria, they can be predicted to be inactivated by the same germicides that destroy lipid viruses and vegetative bacteria. 1. Also, the growing stage of a species (such as the vegetative cell of bacteria, the trophozoite of protozoa, or the larval form of worms) is less resistant than the same organism's survival form (the bacterial spore, protozoan cyst, or worm egg). 115, Jalan Kepayang, Off Jalan Kuching, 51200 Kuala Lumpur, MALAYSIA, Disinfectant, Sanitizer, and Antiseptic Testing, Biocompatibility and Ecotoxicology Studies, https://www.chemanager-online.com/en/restricted-files/215118. 16.
