PPT-BACTERIA as a PATHOGEN! ARCHAEBACTERIA

Methanogens Methanogens are obligate anaerobes that will not tolerate even brief exposure to air O 2 Anaerobic environments are plentiful however and include marine and freshwater sediments bogs and deep soils intestinal tracts of animals and sewage treatment facilities .

Microbiology. Bacteria can infect human beings, animals and plants. They are pathogenic but sometimes this ability to infect is a boon. There are some organisms that are pathogenic to insects, pests and kill a wide variety of insects and can be used as Bio Control Agents.
