How is Bacteria dissimilar from Virus?
Bacteria are unmarried celled prokaryotic microorganisms living inward a multifariousness of environments such every bit extreme mutual depression temperature as well as estrus atmospheric condition or fifty-fifty within an organism.
Viruses are obligate intracellular parasites which remove a living host for its survival. The fence on the status of virus every bit living or non-living is even as well as then open. Undoubtedly, viruses tin move considered every bit sub-cellular particles that present approximately properties of life.
Bacteria | Virus |
Unicellular prokaryotes (without a truthful nucleus) | Sub cellular or acellular particles or without cellular scheme |
Visible nether chemical compound lite microscope ( 200-5000 nm inward diameter) | Only visible nether electron microscope ( xx to 400 nm inward diameter) |
Can alive within or exterior host. Living inward a multifariousness of environments. | Strict intracellular infectious agents, e'er requires a living host. |
Bacteria are living unicellular organism exhibiting properties of life such every bit cellular organization, metabolism, reproduction, homeostasis etc. | Viruses are considered every bit a edge business betwixt living as well as non-living things. It exhibits approximately properties of life such every bit presence of genetic material, might to replicate within the host, answer to heat, chemicals etc. See more: Are viruses living or non-living? |
Bacteria are living as well as cannot move crystallized. | Virus tin move crystallized preserving their living properties. |
Basic bacterial shapes are coccus (spherical), bacillus (rod-shaped), as well as spiral (twisted). | Viral shape: helical, cubical, binal or complex symmetry |
A typical prokaryotic jail cellular telephone alongside DNA, cytoplasm, ribosome, plasmid, peptidoglycan jail cellular telephone wall as well as flagella | No cells. Only genetic cloth surrounded yesteryear a poly peptide coat called capsid. In approximately viruses similar HIV, an outer envelope is acquaint exterior capsid. |
Genetic cloth is e'er deoxyribonucleic acid | Genetic cloth tin move deoxyribonucleic acid or RNA, never both together |
DNA is e'er double stranded | DNA or RNA tin move unmarried stranded or double stranded |
Cellular mechanism for deoxyribonucleic acid replication as well as poly peptide synthesis. | No cellular machinery. Replication of genetic cloth as well as poly peptide synthesis using mechanism of the host |
Reproduce yesteryear itself yesteryear binary fission, an asexual reproduction method | Inject genetic cloth into the host as well as replicates within the host using hosts cellular machinery; either causing breakage of jail cellular telephone releasing intact infectious virions (lytic cycle) or attaching to the host genome every bit prophage as well as replicate along alongside host genome replication (lysogenic cycle) More details: lytic vs lysogenic cycle |
The bulk of bacteria 90% are harmless, or beneficial, or fifty-fifty essential to life. Only less than 10% are harmful as well as illness causing. | Viruses are harmful infectious agents. But genetically engineered viruses are widely used inward rDNA applied scientific discipline as well as factor therapy every bit vectors. Lentivirus inward factor therapy as well as phage vectors similar cosmid inward rDNA technology |
Bacteria oft effort localized infection (in i role of the trunk or confined to an organ) as well as oft associated alongside fever. Eg: Skin infection(eczema),wound infection | Virus oft effort systemic infection (spreads throughout the body) as well as may or may non possess fever. Eg: AIDS |
Bacterial infection is treated alongside antibiotics Eg: Penicillin, Amoxicillin etc | Antibiotics cannot kill viruses. Vaccines are widely used to foreclose viral infection. Eg: Varicella (chickenpox) vaccine, Measles, Mumps as well as Rubella (MMR) vaccine |
Common Bacterial diseases: Food poisoning: Escherichia coli Tuberculosis-Mycobacterium tuberculosis | Common Viral diseases: Common cold: Corona virus, Rhino virus etc Chickenpox caused yesteryear Varicella zoster virus |
