Bacteria occupy their own domain of life. The domain Eubacteria is tremendously diverse and embraces no fewer than 30 distinct phyla, according to the LSPN classification schema. Because of the eagerness with which bacteria exchange genes across species barriers via lateral gene transfers, firm classifications according to lineage are difficult to establish with certainty.Know More
Taxonomists divide life into major suborders, chiefly domain, kingdom, phylum and class. Bacteria belong to the domain Eubacteria, which is one of the three domains of life on Earth. According to Wikipedia, the old designation for bacteria, Prokaryota, can be used only to distinguish bacteria and archaeans from the plants, animals and fungi of Eukaryota and is therefore of limited value. Within Eubacteria, organisms are grouped into phyla and classes, though these levels of classification were developed for eukaryotes and cannot take into account the frequency with which bacteria trade genetic material.
Traditional lines of phylogeny begin to break down at levels below class, as bacterial "species" rarely exist in genetic isolation, notes Wikipedia. Lower-level classification thus becomes largely a matter of opinion, as the majority-similarity rule for identifying a bacterial species, if applied to mammals, would group humans, apes and monkeys together as a single "species."Learn More
The five kingdoms in the classification system of life are animals, plants, fungi, prokaryotes and protoctists. Organisms are classified according to various characteristics that they share, and the kingdom classification is based on their cells. The kingdom is the first division of living organisms.Full Answer >
Spirilla bacteria are Gram-negative bacteria that may cause bacterial diarrhea, adenocarcinoma and peptic ulcers.These bacteria are one of several varieties of bacteria that cause illness or disease in humans; mycoplasmas, chlamydiae, spirochetes and mycobacteria are other virulent and potentially destructive organisms. Spirilla bacteria are identified by their unique body shapes, which resemble spiral pasta noodles, and the type of physical harm that they cause to humans.Full Answer >
The bacillus Subtilis gram stain is a way to test if a patient is infected by the bacteria. Bacillus Subtilis is an endospore.Full Answer >
Cocci bacteria are bacteria that are spherical or oval in shape. The three basic shapes of bacteria are coccus, bacillus and spiral. Cocci bacteria can form arrangements that have different names.Full Answer >
