What are the types of resistance to disease?
It will be discussed under three main headings for which the least unsatisfactory terms probably are race,specitic, race non-specific and non-host resistance.
What is animal disease resistance?
Disease resistance is the ability of animals to inhibit the growth of invading pathogens within the body, which is influenced by the interaction of the host immune system, host genetics, and the pathogens.
Is it possible to breed animals that are resistant to a disease?
Breeding for improved general disease resistance The answers to these questions are: YES and YES! Together with colleagues of the research groups Animal Breeding & Genomics and Adaptation Physiology and partners of the breeding organisation Hendrix Genetics, I measured natural antibody levels in layer chickens.
Which indigenous breeds of cow has more resistance to diseases?
It is to be noted that the N’Dama breed of cattle native to Africa is naturally resistant to this disease.
What is the difference between disease tolerance and disease resistance?
Relative to a susceptible plant, disease resistance is the reduction of pathogen growth on or in the plant (and hence a reduction of disease), while the term disease tolerance describes plants that exhibit little disease damage despite substantial pathogen levels. Disease outcome is determined by the three-way interaction of the pathogen.
Why are different types of disease resistance used in plants?
Resistance conferred by a single gene is usually relatively easy for pathogens to overcome. For this reason plant breeders usually try to combine several different types of disease resistances so that the pathogen has to overcome more than one factor to enable it to grow on the plant.
What do you call a resistance to disease or poison?
Cyanide is an example of a toxin. Bacteria and viruses are examples of pathogens. Resistance to a disease or poison is called immunity. For instance, once a human becomes infected with smallpox, assuming he or she survives, they can… See full answer below. Become a Study.com member to unlock this answer!

Are there any drawbacks to disease resistance?
Another drawback to resistance is that depending on the host pathogen system, resistance is sometimes not long lasting as new pathogen strains quickly develop, and further research and breeding is constantly needed. Resistant varieties are not available for all crops.
What is a resistant infection?
The resistant bacteria that survive are able to multiply, spread and cause further infections in the individual, family, community, or health care setting. In turn, these infections are more resistant to another round of the same or similar antibiotic.
What is the most common bacterial infection?
Some of the most common bacterial infections include: Salmonella is a type of infection often described as food poisoning. Escherichia coli (E. coli) causes gastrointestinal (GI) distress. Tuberculosis is a highly contagious disease caused by the Mycobacterium tuberculosis bacteria.
Is MRSA an infectious disease?
MRSA is an infectious disease according to the infectious disease specialists at the Centers for Disease Control (CDC). MRSA or Methicillin -resistant Staphylococcus aureus is a more dangerous form of the common staph infection.
