    new roots to replace those killed by the pathogen, but the newly developed root system may only support the plant when adequate moisture is available. Such plants may not show above ground symptoms well enough to be culled in the nursery prior to sale. As several pathogens can produce the same symptoms, and two or more pathogens may be affecting the nursery crop, nurseries need access to a professional diagnostic laboratory. Accurate identification of pathogens is essential to allow the correct decision

  • Green Tea Pathogens

    862 Words  | 4 Pages

    Increasing incidences of antibiotic resistance among pathogens has created a demand to explore alternative treatment approaches. One such approach involves evaluating plant derived compounds for their activity against drug resistant pathogens. This study aims at examining the effect of green tea leaf extracts (GTE) on Metallo-β-lactamase (MBL) producing gram negative uropathogens. An ethanolic extract of GTE was prepared using soxhlet apparatus and its effect was studied on seven gram negative MBL

    The human immune system allows the human body to protect itself from foreign particles and pathogens. When mounting an immune response, the first stage is non-specific; this involves phagocytes which engulf and destroy pathogens using chemicals or enzymes. This response occurs without regard for the pathogens structure and the antibodies it presents (Schindler). In 2011, the Nobel Prize in Physiology or Medicine was awarded to Bruce A. Beutler and Jules A. Hoffmann for their work in the “activation

    Transgenesis is an advanced biotechnological technique by virtue of which introduction of new genes to a species belonging to an entirely different species is carried out. The transferred foreign gene is known as a ‘Transgene’. Plants in which the introduction of foreign gene or genes from another unrelated plant or even a different species have been carried out artificially are referred to as ‘Transgenic plants’ or ‘Genetically Modified Plants’. Similarly the animals in which foreign gene/genes

  • Explain Three Conditions That Create Opportunities For Pathogens To Be Harmful In A Human

    conditions that create opportunities for pathogens to become harmful in a human. There are many conditions that create opportunities for pathogens to be harmful for humans. The first is when the immunity has already been compromised by an infection. In cases like this, there is the chance of other pathogens to cause opportunistic infections in such host. Another condition is if the human host does not keep proper personal and environmental hygiene. Many pathogens thrive in dirty environments and if

  • Innate Immunity Essay

    1413 Words  | 6 Pages

    the innate immunity is referred as nonspecific because it defends against any and every type of pathogen. It does not target just one pathogen. This type of immunity includes mechanism like physical barriers, chemicals in the blood and internal pathogen-fighting cells and proteins. 5 examples of first line of defense: - Epidermis of skin: a barrier that protects the inside of the body from pathogens. The reason why the skin is non-specific is because it acts as a physical barrier. - Hairs: act

    The adaptive immune response adapts to the infecting pathogen. For adaptive immunity, there is a difference in the way lymphocytes recognize pathogens. During infection, only lymphocytes that have receptors that recognize that specific pathogen are selected to participate in the adaptive immune response. These pathogen-specific lymphocytes then undergo what is called clonal selection and expansion to proliferate and differentiate to become

  • Disease Vector Essay

    the roles and importance of disease vectors in the transmission of diseases. 25 pts. A disease vector is any agent that transmits and carries an infectious pathogen into another living organism. These vectors have immunity to the pathogen and thus allows for the successful transport of the pathogen. Not every vector is able to carry every pathogen and ecological restrains also limit the spread of the disease due to the inability of the vector to survive in different kinds of environments.
