Atypical Bacteria vs. Typical Bacteria
Atypical bacteria typically do not comprise a cell wall whereas typical bacteria comprises a cell wall. Atypical bacteria remain colorless with Gram staining whereas typical bacteria can either Gram-positive or Gram-negative. The cells of atypical bacteria are relatively small whereas the cells of typical bacteria are large. The atypical bacteria are identifying as the incomplete bacteria whereas typical bacteria are known as zoonotic as these typical bacteria can pass from animals to humans and vice-versa. The atypical bacteria are 0.1-0.3 μm in size whereas the size of the typical bacteria is about 0.5-0.8 μm. The atypical bacteria do not comprise a cell wall like common bacteria whereas the typical bacteria comprise a cell wall made up of peptidoglycans. The reproduction of atypical bacteria is complicating, but typical bacteria reproduce through cell division. Atypical bacteria are obligate parasites while typical bacteria can either parasitic, mutualistic, or predators. Atypical bacteria need a living host or profoundly enrich media for the development whereas typical bacteria cultivate on artificial media with minimal growth factors.
What are Atypical bacteria?
Atypical bacteria are an association of bacteria that do not comprise a cell wall. These bacteria do not contain a cellular wall like common bacteria. They are known as incomplete bacteria. Atypical bacteria are obligate parasites. They require a host for their survival. These bacteria can travel from animals to humans and vice versa. The spreading of atypical bacteria can occur by the air shared by both parts. These bacteria are relatively small compare to the common bacteria, and their shape varies. Atypical bacteria is the reason for upper and lower respiratory infections such as pneumonia, especially in infants. The other forms of atypical bacteria infect the genital areas of males and females. Due to the deficiency of a cell wall, atypical bacteria do not color by Gram staining. They are neither Gram-positive nor Gram-negative. Such bacteria interact with the cells of the body and then cause an illness. Bird flu is an example of an infection causing by such atypical bacteria. Examples of atypical bacteria are chlamydiae, mycoplasmas, and other airborne bacteria.
What are the Typical bacteria?
Typical bacteria are the standard form of unicellular prokaryotes. They can live in diverse environments. Bacteria are prokaryotes; they do not comprise membrane-bound organelles with a nucleus, mitochondria, chloroplasts, etc. Typical bacteria contain a cell wall and capsule close to the cell membrane. Typical bacteria can classify as either Gram-positive or Gram-negative. Specific genera of Gram-positive bacteria produce endospores to survive under unfavorable growth conditions. They contain a single, circular double-strand DNA molecule as their genetic material inside the cytoplasm. Every cellular process arises in their cytosol including protein synthesis, cellular respiration, DNA replication, etc. Typical bacteria are single-celled organisms as they can reproduce by division. Bacteria contain DNA and RNA codes just like the normal cells of the body. Some bacteria provide a new covering on the cell wall known as a plasmid. The plasmid makes a bacterium more potent to the standard antibiotic. Some of them contain flagella and pili-like outer structures. Typical bacteria produce energy either by photosynthesis or by the oxidation of chemical compounds. The main form of asexual reproduction in typical bacteria is binary fission. Most of the typical bacteria are not harmful to other organisms. Some of them are pathogenic.
