Three methods are used mainly to cultivate viruses: 1ANIMAL INOCULATION: First used human volenteers for work on yellow virus fever. Land Steiner and Poper used monkey for isolation of polioviruses Most widely used animal is white mice. Animal inoculation have several disadvantages as Immunity may interfare with viral growth and the animal may harbour latent viruses. 2 EMBRYONATED EGGS: Method was developed by Burnet and virus can be inoculated in several routes as in chorio allantoic membrane, allontoic membrane, in to ammniotic cavity and also in yolk sac. 3 TISSUE CULTURE: The culture of whole organ or tissue fragment as well as dispersed cells on a nutreint medium is used. It can be done by three ways. A)ORGAN CULTURE: Embryonic organ or mall tissue fragments are cultured in vitro in such a manner that they retain their tissue architecture. B) EXPLANT CULTURE: Fragment of minced tissue can be grown on explant e.g. Adenoid tissue explant culture for adenovirus. C) CELL CULTURE: Dispersed or loosed cells are used in that method to grwo viruses . First washed with salt solution they dissociated in component cell by using protolytic enzyme such as trypsin and mechanical shaking. Presence of EDTA helps in disspersion of cells. It can be again divided in different parts. Primary culture Diploid culture and Contineous culture.
Well their are many different kinds of viruses but most all go down by AVG- anti virus
When you sanitize something, you are removing any germs or viruses that could be on the item. this completely stops the spread of germs and viruses, as long as that item remains sterile.
The only way viruses can replicate is by parasitizing living cells and using the cell's mechanisms to replicate their genetic materials and protein components.
Biochemical tests are not effective for identifying viruses because viruses lack the necessary biochemical machinery to conduct metabolic processes. Viruses are obligate intracellular parasites that rely on host cells to replicate, making them difficult to culture and study using traditional biochemical methods. Instead, techniques like nucleic acid amplification and serological testing are used to identify and characterize viruses.
Bacteria and viruses can be spread through similar methods such as sneezing, coughing, or touching contaminated surfaces. However, viruses typically require a host cell to replicate, while bacteria can multiply on their own. Antibiotics are effective against bacteria but not viruses.
One way is to always install applications from trusted sources. Also, since most viruses are transmitted through the Internet, it is advisable to stay off it if you don't have an antivirus.
Biochemical tests are generally not used for the identification of viruses. Instead, techniques such as serological assays, nucleic acid amplification tests (PCR), electron microscopy, and viral culture methods are commonly used to identify viruses. These methods help to detect specific viral proteins or genetic material in samples.
Computer viruses are created by malicious individuals who write code to infect computers and cause harm. These individuals use various methods such as exploiting software vulnerabilities, social engineering, and phishing to spread the virus. They may also use tools like code injection and encryption to make the virus harder to detect and remove.
Yes, filters can remove some bacteria and viruses from water through physical filtration. However, it's important to note that not all filters are effective in removing all types of bacteria and viruses, so it's essential to use filters that are tested and certified for this purpose. Additionally, other methods such as UV light or chemical disinfection may be needed for complete removal of bacteria and viruses.
A main component of virology (the study of viruses) is virus classification. The method for classifying viruses largely involves classifying the host cells that they infect. The physical characteristics of viruses are observed electron microscopy, NMR spectroscopy, and X-ray crystallography.
Viruses cannot be killed in the traditional sense like bacteria, as they are not considered living organisms. However, they can be effectively neutralized and destroyed through methods such as proper hand hygiene, disinfecting surfaces, and through antiviral medications or vaccines designed to target specific viruses.
