Pathogens are defined as microscopic organisms, including viruses, bacteria, fungi, and parasites that can cause diseases in humans, animals, and plants. These invisible agents can cause a wide range of infections, from mild illnesses like the common cold to severe and potentially life-threatening diseases like COVID-19, Ebola, and HIV. They are al...
Understanding the intricacies of molecular biology behind pathogenicity is crucial in developing effective treatments and preventing the spread of infectious diseases. By considering both infectivity and virulence, researchers, wellness professionals and medical professionals can gain insight into how pathogens interact with their hosts and develop...
There are a variety of pathogens which are discussed below. Algaeare a diverse group of photosynthetic organisms that can be found in various aquatic environments. While some types of algae are beneficial, others can be harmful and cause disease in marine organisms. The diversity of algae pathogens and the significant impact they can have on marine...
As discussed in the section above, pathogen-host relationships are tightly regulated in nature. They are governed by co-evolution. Here we discuss the vast majority of hosts for various pathogens. Bacteria, while being serious pathogens to humans, animals and plants can also act as hosts for pathogens, which are organisms that cause disease. These ...
Pathogenic diseases are a burden on human lives and the economy. Treatment options and antimicrobial therapy have widened for most diseases over the years. Yet, the ongoing research endeavors to better the prevention and control measure. There are still some pathogens that are beyond the control of human efforts and create ruckus when spread unabat...
Many pathogens have the ability to undergo sexual interaction, a process that involves genetic transformation, meiosis, and fertilization. Sexual interaction among bacteria occurs between cells of the same species through genetic transformation, where DNA from a donor cell is transferred to a recipient cell and integrated into the recipient’s genom...
GCSE Biology Key Words *Deamination: A process occurring in the liver that removes the amino group from an amino acid to produce ammonia. *Dialysis: A method of treating kidney failure or disease where the blood is artificially filtered to remove waste and toxins.
Jun 9, 2023 · Ensuring synchronization between processes which make up a complex system requires functional interdependence, with multiple mechanisms cooperating to achieve a predetermined final state. Interrelationship involves multiple systems, each equipped with its own regulatory mechanism and hence operating as a distinct entity.
