    of this event a pathogen present in one reservoir population will spread the pathogen to a new host or reservoir. An example of this is animal to human contact. For example, Ebola is thought to have been transmitted to humans by a bat. Meaning that the bat was the first reservoir host and passed it to a human host, a new population. Additionally, opportunistic pathogens, mutations, evolution, and reassortment could possibly lead to a new kind of infection. An opportunistic pathogen has the…

    in defense mechanisms to aid against foreign substances, pathogens, toxins and diseases. The type of immunity used by the body depends on the type of pathogen and whether that pathogen has already entered the body. In cases where the pathogen is inside the body, an internal defense is used to aid in fighting the pathogen. The body may start running a fever or start inflammation to rid itself of the pathogen. In cases where the pathogen has not yet entered the body, defenses such as tears,…

    active immunizations the first one is naturally acquire, that is when a person has contact with a pathogen and then the person gets sick but their body recovers. Their body then knows how to deal with that pathogen and they are able to fight it off, we can be immune to those pathogens for lifelong for example measles. The second type is artificially acquire, that is using vaccines to fight pathogens. The second type of immunization is Passive Immunization, which means that immunity is pass from…

    positive for containing harmful toxins (Horton, 2003). Since the bay runs throughout six states: Delaware, Maryland, New York, Pennsylvania, Virginia, and West Virginia, many people on the east coast are affected each year. One of the thousands of pathogens affecting humans throughout the bay is Amyotrophic Lateral Sclerosis also known as ALS. When ALS enters in the human body it kills motor neurons in the brain and spinal cord, which slowly paralyzes the body (McAuliffe, 2011). ALS is known…

    Results Primer design and LAMP reaction Among 40 different primers (OPA 1-20 & OPB 1-20 series) screened by RAPD PCR for differentiating the Mycosphaerella eumusae from other leaf spot causing fungal pathogens in banana, only the primer OPB 10 has generated a unique amplicon specific to M. eumusae at 1300 bp size. A total of nine different sets of LAMP primers were designed based on this specific SCAR derived RAPD marker sequence of M. eumusae and screened for the production of LAMP products…

    The need for antibiotic sensitivity testing is urgent due to the surge of antimicrobial resistant pathogens in recent years. Antimicrobial resistance hinders the prevention and treatment of the infections caused by parasites, bacteria, fungi and viruses. Antimicrobial resistance is the resistance of a pathogen to an antimicrobial that was used to treat any infections caused by that particular pathogen. Antimicrobial resistance is a global problem. Antibiotic resistance hampers the effectiveness…

    cell, is initiating innate immunity. Innate immunity involves phagocytes binding to the pathogen using its pattern recognition receptors, such as toll-like receptors (TLRs), which binds to the pathogen-associated molecular patterns (PAMPs) that are present on pathogen. After binding to its cell surface, it starts ingesting the pathogen using either phagocytosis or macropinocytosis, and destructs the pathogen either by forming a phagolysosomes or secretion of soluble factors. Then, phagocytes…

    and find out the natural phenomena that impacts dying trees in our area. The key elements we are investigating is the plant pathogen,Phytophthora ramorum and the trees that are being affected and the host,Umbellaria californica. This is significant since billions of trees are dying at a rapid pace every year due to a new pathogen that causes Sudden Oak Death. The pathogen is called Phytophthora ramorum and it was recently discovered in the year of 1995, which at this point has a high…

    Antibodies respond to a pathogen in three main ways. Firstly, they may bind directly to the pathogen which prevents the pathogens from entering or causing damage to other cells. Antibodies can also stimulate other cells in the immune system to destroy the pathogen. Opsonisation can also be used to mark the pathogens. Phagocytes and the pathogens both have a negative charge so naturally repel one another. The antibody binds to the pathogen and neutralises the charge on the pathogen so that the…
