susceptible

Examples of susceptible in the following topics:

• Chain of Transmission

  • Microorganisms carried in this manner can be dispersed widely by air currents and may become inhaled by a susceptible host within the same room or over a longer distance from the source patient, depending on environmental factors; therefore, special air-handling and ventilation are required to prevent airborne transmission.
  • Direct-contact transmission involves a direct body surface-to-body surface contact and physical transfer of microorganisms between a susceptible host and an infected or colonized person, such as when a person turns a patient, gives a patient a bath, or performs other patient-care activities that require direct personal contact.
  • Direct-contact transmission can also occur between two patients, with one serving as the source of the infectious microorganisms and the other as a susceptible host.
  • Indirect-contact transmission involves contact of a susceptible host with a contaminated intermediate object, usually inanimate, such as contaminated instruments, needles, or dressings, or contaminated gloves that are not changed between patients.

• Host Risk Factors

  • Individuals who are weak, sick, malnourished, have cancer, or are diabetic have increased susceptibility to chronic or persistent infections.
  • Those who are weak, sick, malnourished, have cancer, or are diabetic have increased susceptibility to chronic or persistent infections.
  • Individuals who have a suppressed immune system or who are on immunosuppressive drugs are particularly susceptible to opportunistic infections.

• Kirby-Bauer Disk Susceptibility Test

  • Kirby-Bauer antibiotic testing (also called KB testing or disk diffusion antibiotic sensitivity testing) uses antibiotic-containing wafers or disks to test whether particular bacteria are susceptible to specific antibiotics.
  • If the bacteria are susceptible to the particular antibiotic from a wafer, an area of clear media where bacteria are not able to grow surrounds the wafer, which is known as the zone of inhibition.

• Cytotoxic Autoimmune Reactions

  • Certain individuals are genetically susceptible to developing autoimmune diseases.
  • This susceptibility is associated with multiple genes plus other risk factors.
  • Immunoglobulins and the T-cell receptors are involved in the recognition of antigens and they are inherently variable and susceptible to recombination.
  • The contributions of genes outside the MHC complex remain the subject of research both in animal models of disease (Linda Wicker's extensive genetic studies of diabetes in the NOD mouse), and in patients (Brian Kotzin's linkage analysis of susceptibility to SLE).

• The Roles of Genetics and Gender in Autoimmune Disease

  • Certain individuals are genetically susceptible to developing autoimmune diseases.
  • This susceptibility is associated with multiple genes plus other risk factors.
  • Immunoglobulins and T-cell receptors are involved in the recognition of antigens and they are inherently variable and susceptible to recombination.
  • The contributions of genes outside the MHC complex remain the subject of research, in animal models of disease (Linda Wicker's extensive genetic studies of diabetes in the NOD mouse), and in patients (Brian Kotzin's linkage analysis of susceptibility to SLE).

• Colonization and Growth

  • Those who are weak, sick, malnourished, have cancer or are diabetic possess an increased susceptibility to chronic or persistent infections.
  • Individuals who have a suppressed immune system are particularly susceptible to opportunistic infections.

• Tissue Tropism in Animal Viruses

  • Viral tropism is determined by a combination of susceptibility and permissiveness: a host cell must be both permissive (allow viral entry) and susceptible (possess the receptor complement needed for viral entry) for a virus to establish infection.

• Relative Resistance of Microbes

  • Most mycobacteria are susceptible to the antibiotics clarithromycin and rifamycin, but antibiotic-resistant strains have emerged.
  • Fungal cells as well as spores are more susceptible to treatments.

• Beta-Lactam Antibiotics: Penicillins and Cephalosporins

  • All penicillins are β-lactam antibiotics and are used in the treatment of bacterial infections caused by susceptible, usually Gram-positive, organisms.
  • Cephalosporins are indicated for the prophylaxis and treatment of infections caused by bacteria susceptible to this particular form of antibiotic.

• The Cardiovascular System

  • Both the cardiovascular system and the lymphatic system are susceptible to diseases caused by microorganisms.
