They are all called bacteria and are in that group. As to these 'special' types we would call them pathogens. Almost any bacteria can become a pathogen if it finds itself in the 'wrong' or not normal environment.
All decay is bacterial (except when the term is used metaphorically, as in social decay).
The term for an organism that causes decay is decomposers, such as bacteria and fungi. they chemically break down organic matter for food. the decay caused by the decomposers is part of a process that produces detritus, small pieces of dead and decaying plant/animal remains.
Oxygen speeds up the oxidation (essentially slow burning) of organic waste. However its main impact is to facilitate the aerobic bacteria which can decompose organics . It should be noted that oxygen can inhibit the Anaerobic bacteria which are significant causes of biological decay.
The main microbes involved in decay are bacteria and algae
Fungi and bacteria eat things. Decay is caused by the growth and reproduction of these decay organisms, which are eating the material which is decaying. You don't see individual bacteria at work because they are microscopic, and you don't clearly see fungi at work, because most of what they are doing is hidden, but you see the result, in the form of decay.
Bacteria are prokaryotic cells that cause disease and decay.
The start of tooth decay is caused by two groups of bacteria Streptococcus Mutans and Lactobacillus.

Bacteria that populate the mouth metabolize simple carbohydrates (sugar) and produce the acid that causes tooth decay. Reducing the bacteria by effective and frequent brushing and flossing can reduce tooth decay. Limiting intake of sugar will also reduce decay. There is also a growing body of research that indicates xylitol as a sugar substitute may also be effective in reducing tooth decay.
Bacteria
bacilli bacteria (Bacillus anthracis) causes anthrax in sheep and humans, and (lactobacillus) causes tooth decay and is also an ingredient in yogurt. Bacilli can cause tetanus (lockjaw) typhoid feaver, tuberculosis, and diphtheria (Milady's Standard Cosmetology ~source)
Bacteria
The domain Bacteria can cause both tooth decay and food poisoning. Dental cavities are primarily caused by Streptococcus mutans, while various types of food poisoning can be caused by bacteria such as Salmonella or Escherichia coli.
no its only a decay
