    What is Cytopathic Effect?

    • Viruses aggultinate red blood cells added to the cell cultures.

    • Visible modifications of infected cells

    • Presence or absence of antibody aganist a given virus

    • Rise in antibody or high titer aganist a given virus, gives evidence that a virus has already caused a viral illness.

    Correct Answer
    A. Visible modifications of infected cells
    Explanation
    The correct answer is "Visible modifications of infected cells". Cytopathic effect refers to the visible changes that occur in cells when they are infected by a virus. These changes can include cell rounding, cell detachment, cell fusion, formation of syncytia, and cell death. By observing these visible modifications, scientists can determine if a virus is present and causing an infection. The other options provided in the question are not related to cytopathic effect and do not provide evidence of viral illness.

    What is the third Method of detection of viruses in a clinical specimen

    Correct Answer
    Direct detection of viral antigens
    Explanation
    The third method of detecting viruses in a clinical specimen is through direct detection of viral antigens. This involves identifying specific proteins or molecules that are unique to the virus being tested for. By looking for these viral antigens, healthcare professionals can confirm the presence of the virus in the specimen. This method is commonly used in diagnostic tests such as enzyme-linked immunosorbent assays (ELISAs) or immunofluorescence assays (IFAs) to quickly and accurately detect viral infections.

    What are some general characteristics of viruses?

    Correct Answer
    they require living cells, cannot grow in artifical media ( or hardly) - multiply by synthesis of nucleic acid protein which are then assembled to form viruses. they vary in size but from 10 nm - 300nm
    Explanation
    Viruses are characterized by their dependency on living cells for replication and cannot grow in artificial media, or only to a limited extent. They multiply by synthesizing nucleic acid and proteins, which are then assembled to form new viruses. Additionally, viruses vary in size, typically ranging from 10 nm to 300 nm.

    What are the two main components of A virus

    Correct Answer
    1. nucleic acid core that carries the genetic code 2. Protein coat - protects the core and carrys the antigens
    Explanation
    A virus consists of two main components: a nucleic acid core that carries the genetic code and a protein coat. The nucleic acid core contains the genetic material of the virus, which can be either DNA or RNA. This genetic material is responsible for the replication and production of new viruses. The protein coat, also known as the capsid, surrounds and protects the nucleic acid core. Additionally, the protein coat may also carry antigens, which are substances that trigger an immune response in the host organism.

    What are the 5 steps of virus replication ( multiplication)

    Correct Answer
    1. Adsorption : The virus adsorbs to receptors on the cell surface. The spikes on the protein coat also act as signal that allows them to search around for good receptors. 2. Penetration and uncoating : virus enters the cell, protein coat is lost and the nucleic acid is released. Becomes undetectable ( eclipse) 3. Syntesis of nucleic acid and protein - The viral nucleic acid redirects the cell metabolism to produce viral protein and nucleic acid. 4- assembly-maturation- viral components are assembled to form mature( infective) virus particles 5- Release - newly formed virus particles are released by either lysis ( destruction) of the cell or budding through the cell membrane.
    Explanation
    The correct answer provides a clear and concise explanation of the 5 steps of virus replication (multiplication). It outlines the process starting with the virus adsorbing to receptors on the cell surface, followed by the virus entering the cell and releasing its nucleic acid. The viral nucleic acid then redirects the cell metabolism to produce viral protein and nucleic acid. The viral components are then assembled to form mature virus particles, and finally, the newly formed virus particles are released through either cell lysis or budding through the cell membrane.

    Name the two main approaches to Viral diagnosis ( just name)

    Correct Answer
    1. Detection of viruses in clinical specimen and 2. Detection of patients immunal response triggered by the virus.( detection of antibodies in the patients blood)
    Explanation
    The two main approaches to viral diagnosis are the detection of viruses in clinical specimens and the detection of the patient's immune response triggered by the virus, specifically the detection of antibodies in the patient's blood.

    Describe the " detection of viruses in clinical specimens" approach to viral diagnosis

    Correct Answer
    A) Visualization by Electron microscopy : since viruses are extremly small B) Effects after inoculation into cell cultures: requires mutiplication and time. C)Direct detection of viral antigens
    Explanation
    The correct answer is A) Visualization by Electron microscopy: since viruses are extremely small. This method involves using an electron microscope to directly visualize the virus particles in a clinical specimen. Since viruses are too small to be seen with a light microscope, electron microscopy is necessary to observe their structure and identify them. This technique allows for the direct detection and identification of viruses in clinical specimens.

    Name three methods that viruses are detected by the effects they made after  incoculation into cell cultures

    Correct Answer
    1) Cytopathetic effects : visible modifications of infected cells 2) haemagglutination : viruses can aggultinate RBC added to the cell culture 3) immunoflouresence : that reveals the presence of viral antigenetic material.
    Explanation
    The question asks for three methods that can be used to detect viruses based on the effects they have on cell cultures. The first method mentioned is cytopathetic effects, which refers to visible modifications in infected cells. This means that when a virus infects a cell culture, it causes noticeable changes in the appearance or behavior of the cells. The second method is haemagglutination, which involves the ability of viruses to cause red blood cells to clump together when added to the cell culture. Finally, the third method is immunofluorescence, which is a technique used to detect the presence of viral antigenetic material in the cell culture.

    Name the two ways Detection of the immune reaction triggered by the patients own immune system.

    Correct Answer
    1- Immunity tests- Presence or absences of antibody aganist a given virus 2- diagnostic Tests - Detecting a high or rise in antibody titer aganist a given virus- evidence that a particular virus has recently caused a viral illness.
    Explanation
    The two ways to detect the immune reaction triggered by the patient's own immune system are through immunity tests, which determine the presence or absence of antibodies against a specific virus, and diagnostic tests, which detect a high or rising level of antibodies against a specific virus, indicating recent viral illness.
