Pathogenic bacteria utilise a number of mechanisms to cause disease in human hosts. Bacterial pathogens express a wide range of molecules that bind host cell targets to facilitate a variety of different host responses. The molecular strategies used by bacteria to interact with the host can be unique to specific pathogens or conserved across several different species. A key to fighting ... Bacteria Characteristics. Introduces bacterial cell shapes and structures. Characteristics of Bacteria. Bacteria are the most successful organisms on the planet. They lived on this planet for two billion years before the first eukaryotes and, during that time, evolved into millions of different species .
Characteristics of bacteria are prokaryotes, meaning they do not have membrane bound organelles, peptidoglycan cell wall, and asexual reproduction, meaning they only The DNA enters the incubated bacteria through holes in the cell membrane, and gets incorporated into the bacterial genome.
