Bacteria (singular-bacterium) are the microscopic unicellular and prokaryotic organisms. In the year 1872 scientist Cohn classified bacteria to 4 major types depending on their shapes are as follow: 1) Cocci: These types of bacteria are unicellular, spherical or elliptical shape. While some of the infections can be easily treated, some of the strains have been shown to resist antibiotic treatment and are therefore deadly. 3 Cellular Evolution Current evidence indicates that eukaryotes evolved from prokaryotes between 1 and 1.5 billion years ago Two theories: 1. Your username will (2) Because there are so many gram-negative rods, they are divided into three categories: respiratory organisms, zoonotic organisms, and enteric and related organisms. 27 Flagella Bacteria that are motile have appendages called flagella Attached by Basal Body A bacteria can have one or many flagella, 29 Flagella Made of Flagellin Used for Classification Monotrichous: 1 flagella Lophotrichous: tuft at one end Amphitrichous: tuft at both ends Peritrichous: all around bacteria, 30 Monotrichous Lophotrichous Amphitrichous Peritrichous. and educationists.

others anaerobic May be free living, parasitic, or symbiotic, 69 Enteric Bacteria Gram negative Can live in aerobic & anaerobic habitats Includes E. coli in intestines Salmonella – causes food poisoning, 70 Chemoautotrophs Gram negative Obtain energy from minerals like iron Found in freshwater ponds, 71 Nutrition, Respiration, and Reproduction, 72 Modes of Nutrition Saprobes – feed on dead organic matter Parasites – feed on a host cell Photoautotroph – use sunlight to make food Chemoautotroph – oxidize inorganic matter such as iron or sulfur to make food, 73 Methods of Respiration Obligate Aerobes – require O2 (tuberculosis bacteria) Obligate Anaerobes – die if O2 is present (tetanus) Facultative Anaerobes – don’t need O2, but aren’t killed by it (E. coli), 74 Bacterial Respiration Anaerobes carry on fermentation Aerobes carry on cellular respiration, 75 Reproduction Bacteria reproduce asexually by binary fission Single chromosome replicates & then cell divides Rapid All new cells identical (clones), 76 Cellular organism copies it’s genetic information then splits into two identical daughter cells, 78 Reproduction Bacteria reproduce sexually by Conjugation Form a tube between 2 bacteria to exchange genetic material Held together by pili New cells NOT identical, 80 Spore Formation Form endospore whenever when habitat conditions become harsh (little food) Able to survive for long periods of time as endosperm Difficult to destroy (heat resistant), 81 Transduction & Transformation Genetically change bacteria May become antibiotic resistant Transformed bacteria pick up pieces of DNA from dead bacterial cells Transduction – viruses carry foreign DNA to bacteria; used to make insulin, 83 Pathogens Called germs or microbes Cause disease May produce poisons or toxins Endotoxins released after bacteria die (E. coli) Exotoxins released by Gram + bacteria (C. tetani). your blog. 1.5 1.5 BACTERIAL STRUCTURE The outer layer or cell envelope consists of two components, a rigid cell wall and beneath it a cytoplasmic or plasma membrane. In the scientific classification established by Carl Linnaeus, each species has to be assigned to a genus (binary nomenclature), which in turn is a lower level of a hierarchy of ranks (family, suborder, order, subclass, class, division/phyla, kingdom and domain). Facultative anaerobes: Those bacteria that do not require O2 but can use it if available. We only Appendages 5. Introducing 3 types of microbe with fact sheets and a wanted poster.
