Difference between Actinomycetes and Bacteria

Main difference

The main difference between actinomycetes and bacteria is that actinomycetes are considered the temporary state of fungi, but they are actually a type of bacteria, whereas bacteria have a simple cell body and are considered a single-celled organism …

Actinomycetes against bacteria

Actinomycetes are considered filamentous bacteria, while bacteria are considered a large group of microorganisms without membrane-bound organelles and having a murine cell wall. Actinomycetes generally belong to the order Actinomycetales, while bacteria are considered a domain. Actinomycetes are gram-positive bacteria; on the other hand, bacteria can be gram-negative or gram-positive.

Actinomycetes are more abundant than for bacteria; on the contrary, bacteria are considered the most abundant forms of microorganisms. Actinomycetes are generally considered a facultative anaerobic; conversely, the bacteria are known as anaerobes, aerobes, or facultative aerobes. Actinomycetes are oval in shape; on the other hand, bacteria can be spherical or rod-shaped.

Actinomycetes produce powdery colonies that adhere firmly to agar and their colonies grow slowly; On the other hand, bacteria produce viscous or distinct colonies, and bacterial colonies grow faster. Actinomycetes produce conidia and hyphae like fungi; conversely, bacteria do not produce such structures. Actinomycetes are generally not motile, while some bacteria are motile and can move.

What are actinomycetes?

Actinomycetes are reflected as the temporary condition of fungi, but are actually considered the form of higher bacteria. The important characteristic feature of actinomycetes is the formation of conidia and hyphae like fungi. Actinomycetes actually differ from fungi due to the presence of murines in the fungal cell wall.

Actinomycetes, as a normal microbiota in animals, live in the soil and in decomposing organic matter. Some species of actinomycetes generally associate with plants by participating in nitrogen fixation. Actinomycetes are usually appropriate for the order Actinomycetaceae, which is further classified into four families: Actinomycetaceae, Strepto mycetaceae, Mycobacteriaceae, and Actinoplanaceae.

The specific part that actinomycetes play is spoilage and decomposition of dead organic substance, while some of the actinomycetes also play a role in the formation of antibiotics such as streptomycin. Some species of actinomycetes are important pathogens, for example, nocardiosis which is caused by Nocardia asteroids, which causes an infection of the brain, lungs or skin of humans.

Other species of actinomycetes cause severe dermatitis in sheep, cattle, horses, and occasionally humans, while some actinomycetes are harmless to higher plants and animals. Actinomycetes are more abundant than in bacteria. Actinomycetes are characteristically considered gram-positive bacteria. Actinomycetes produce dry colonies that branch purposefully on agar, and their colonies grow slowly and are not motile.

What are Bacteria

Bacteria have a simple cell structure and are considered a unicellular organism with a large group of microorganisms without membrane bound organelles and having a murine cell wall. Bacteria are generally the type of unicellular prokaryotes whose cell wall is made up of murine polysaccharides. They lack a nucleus. The genetic material of bacteria consists of a double-stranded circular DNA found in the nucleoid. Bacteria suffer from 70S ribosomes. Many bacteria genes are involved in extrachromosomal components, eg plasmids.

Some bacteria are mobile, can move from one place to another and have flagella. The flagellum of bacteria is produced from approximately 20 proteins with an additional 30 types of proteins that are essential for bacterial training and harvesting. Some basic types of bacteria are Bacillus, Coccus, and Spirillum.

Bacteria reproduce through asexual reproduction through the process of binary fission. Sexual reproduction in bacteria rarely occurs in the conjugation process. The habitats of bacteria include water, soil, acidic hot springs, radioactive waste, and some abysmal parts of the earth. They can also live as parasites and as symbiotic relationships with animals and plants.

Almost all animal and human life depends on bacterial production for their existence and survival because only bacteria possess the important genes and enzymes that are necessary for vitamin B12, which is also known as cobalamin, which is provided through the chain food to all organisms. . Characteristically, the bacteria could be any gram-negative or gram-positive bacteria.

Key differences

  1. Actinomycetes are considered filamentous bacteria, while bacteria are considered a large group of microorganisms without membrane-bound organelles and having a murine cell wall.
  2. Actinomycetes generally belong to the order Actinomycetales, while bacteria are considered a domain.
  3. Actinomycetes are characteristically considered gram-positive bacteria; on the other hand, the bacteria could characteristically be any gram-negative or gram-positive bacteria.
  4. Actinomycetes are more abundant than for bacteria; on the contrary, bacteria are considered the most abundant forms of microorganisms.
  5. Actinomycetes are generally considered a facultative anaerobic; conversely, the bacteria are known as anaerobes, aerobes, or facultative aerobes.
  6. Actinomycetes are oval in shape; on the other hand, bacteria can be spherical or rod-shaped.
  7. Actinomycetes produce dry colonies that ramify purposefully on agar; on the other hand, bacteria produce fatty or distinct colonies.
  8. Actinomycete bacteria produce colonies that usually produce slowly, whereas bacterial colonies normally produce faster.
  9. Actinomycetes produce conidia and hyphae like fungi; conversely, bacteria do not produce such structures.
  10. Actinomycetes are generally not motile, while some bacteria are motile and can move.
Final Thought

The above discussion concludes that actinomycetes are considered the transition state of bacteria fungi, but they are a type of bacteria and are abundant in number but close to bacteria, while bacteria have a simple cell structure and a single-celled organism. and abundant in all microorganisms.
