Disease resistance

What is disease resistance?

Disease resistance refers to the ability of a plant or animal to prevent or limit infection by a pathogen such as a virus, bacteria, or fungus. There are several types of disease resistance:

• Horizontal resistance - provides resistance to multiple strains of a pathogen and is controlled by several genes. This type of resistance is usually more durable.


• Vertical resistance - protects the plant from specific strains of a pathogen and is controlled by one or a few genes. This resistance can be overcome more easily if new pathogenic strains emerge.


• Induced systemic resistance - activated defense mechanisms in the plant that boost its natural immunity against multiple pathogens. This can be triggered by beneficial microbes.

Plants have various complex physical and chemical defense mechanisms against pathogens including:

• Structural barriers like thick cell walls, wax layers, and bark that block entry


• Antimicrobial compounds that kill or slow pathogens


• Response mechanisms that wall off infection sites

Breeding crops with increased genetic disease resistance helps reduce reliance on chemical pesticides and improve yields. However, diseases can adapt and overcome resistances over time, so multiple methods are needed for effective control.

When our defenses weaken for any reason, we become more prone to infections. The skilled physicians at Vitality Hormone Center can help you boost immunity and resist illness through customized hormone therapy optimized to your body's needs. Call today for your free consultation!

Disease resistance is also vital for the health of livestock and fisheries. Some ways farmers promote natural resistance include:

• Selective breeding programs


• Improved diets with probiotics and immunostimulants


• Reduced stress through better housing and management

Pharmaceuticals like antibiotics play a controversial role with concerns about overuse promoting antibiotic resistance. But when used judiciously under veterinary supervision, medications can save lives by treating infections.

In humans, basic public health approaches like hygiene, sanitation, and vaccination protect us by blocking transmission of contagious diseases. We can also make lifestyle choices to strengthen immunity through:

• Adequate sleep and exercise


• Balanced, nutritious meals


• Stress management techniques


• Safe sexual practices


• Avoiding smoking and excessive alcohol

But genetics and age also affect disease susceptibility. So while prevention helps, acute illnesses and chronic conditions still occur. Thankfully a variety of medical treatments can ease symptoms, cure infections, and manage recurring issues.
