Spores are highly resistant forms of bacterial cells.
Domain Bacteria contain the oldest known fossils of cells in bacterial cells.
Group C. I'm in microbiology right now. Group A are vegetative forms of most bacteria and enveloped viruses that are easily killed by disinfectants. Group B are more difficult to kill, like tuberculosis baccillus and unenveloped viruses. and Group C have highly resistant endospores.

endospore
a group of specialized cells first forms into tissue, and a group of tissue forms into organs.
Domain Bacteria contain the oldest known fossils of cells in bacterial cells.
Bacterial spores are extremely resistant and can survive most forms of disinfection and inadequate sterilisations
Microorganisms that are in a dormant or contain endospores are the most resistant.

Certain Isolation techniqiues are based on the concept that if an individual bacterial cell is separated from other cells and provided adequate space on a nutrient surface, it will grow into discrete mound of cells called a colony

Histones function in the packaging of DNA as well as in regulation of gene expression in eukaryotic (and some bacterial) cells. Histone proteins are among the most highly conserved proteins in eukaryotes, emphasizing their requirement for the survival of more complex life forms. Cells deficient in histones likely would not survive as the complex genomes of eukaryotes would not have the necessary levels of regulation as well as the DNA would not be efficiently packed and would be fragile and highly susceptible to damage.

Binary Fission and Conjugation are two common forms of bacterial reproduction.
Bacterial Meningitis is a spore-forming bacilli. Bacteria typically reproduce by an asexual process called binary fission. Also called transverse division. A process by which one cell increases in size and forms two cells which are identical to each other.
Also known as "superbugs", antibiotic resistant bacteria have evolved to a point that our usual antibiotics won't kill them. VRE and MRSA are common forms of antibiotic resistant bacteria.
