Bacterial diseases of plants are more than just unsightly; they are often destructive to plants. Fire blight is a destructive bacterial disease that is especially threatening to rosebushes and pome fruit trees. While there are dozens and dozens of bacterial diseases, listed below are only four that I find interesting. Legionnairesa€™ DiseaseIn July of 1976, over 10,000 war veterans belonging to the American Legion held a convention in Philadelphia. President Ford prepared his administration to vaccinate citizens against swine flu and impose quarantines.
Now known as Legionnaires a€™ disease and treated with antibiotics, between 8,000-18,000 people are hospitalized every year due to the illness. The bacterium grows best in warm water and is commonly found in large air conditioning systems, shower heads, hot tubs, hot water tanks, and large plumbing systems and is not spread from person to person.
SyphilisIt is believed that 20% of insane asylum patients in the 19th century suffered from syphilis, a sexually transmitted disease. Syphilis, in the final stage, causes a condition known as General Paralysis of the Insane (GPI). Primary Stage: The first symptoms appear 10-90 days after a person has had direct contact with a lesion or sore, also called a chancre. Secondary Stage: A rash without an itch appear on the bottoms of the feet and the palms of the hands approximately 6-8 weeks after sore(s) disappear. Third Stage: Also known as the latency period because the symptoms are hidden, this stage can begin anywhere from 2 to 30 years after the initial infection. Fourth Stage or Tertiary Stage: The bacterium begins to eat away at bones, vital organs of the body including the brain (causing GPI) and the central nervous system, and causes gradual blindness.
Diagnosing syphilis is simple and inexpensive via a blood test or analyzing tissue from a sore. If someone has suffered from syphilis less than a year, one injection of Penicillin will cure it; however, syphilis that has been present longer than one year requires additional injections. All states in the US required a syphilis test prior to issuing a marriage license, but most states have eliminated this requirement. Throughout history, people suffering from leprosy were ostracized and forced to live in leper camps. Despite the existence of leper camps, leprosy is not highly contagious and is transmitted through direct contact with drops from the nose, mouth, or eyes of someone with leprosy who is not undergoing treatment. Treatment, developed in the early 1960s, consists of multi-drug therapy and can last for as little as six months or as long as three years.

Rocky Mountain Spotted FeverNamed after the region where the disease was first discovered in 1896, Rocky Mountain Spotted Fever is caused by the bacterium Rickettsia rickettsii and is the most severe tick-borne illness in the United States. Diagnosis is determined by clinical signs and lab work, and treatment is a tetracycline antibiotic. The bacteria travel through the bloodstream and attack joints, kidneys, heart, lungs and the nervous system.


It is believed once you are infected with Rocky Mountain Spotted Fever that it provides lifetime immunity.

The University of Minnesota explains that there are more than 160 species of plant bacteria, each with its own growth rate.
Plants that are infected with bacterial leaf spot will develop dark-colored, water-soaked spots that are accompanied by encasing yellowing halos. This disease lies dormant in the plant and in decomposing matter that lies around the plant. While bacteria are essential to life on earth, there are some forms of bacteria that wreak havoc on the human body and often lead to disfigurement and death.
It took six months to determine the illness was due to a bacterium, Legionella pneumophilia (named after the people suffering the disease), that was found in the hotela€™s air conditioning system. Chest x-rays, sputum cultures, and tests on blood and urine are able to detect the bacteria in the body. Though the initial sign of GPI is depression, it slowly progresses to memory and intellectual impairment, grandiose delusions, over-excitability, and extreme personality changes.
It is transmitted through sexual contact and from an infected mother to her baby during pregnancy.
People will often suffer from fatigue, fever, sore throat, weight loss, patchy hair loss, headaches and muscle aches in this stage of syphilis. Because this stage can last for so many years, people often do not enter the fourth and final stage of syphilis and die, instead, from some other cause of death. Possibly due to the elimination of syphilis testing, there seems to be an increase in the number of syphilis cases in the United States.
Caused by the bacterium Mycobacterium leprae, leprosy is a chronic bacterial infection characterized by lesions and nodules appearing on the body. Presently, there are only about 100 cases of leprosy per year in the United States, although leprosy is still prevalent in parts of Asia and Africa, where leper camps still exist.
Symptoms can take 4-8 years to appear after exposure, and children are more susceptible to leprosy than adults. If left untreated, leprosy can cause severe nerve damage to the hands and feet, rendering limbs useless.
It is essential that treatment begin in the first week in order to avoid lasting effects of the disease. If left untreated or undetected, complications include spinal meningitis, heart and kidney failure, blood clotting, and gangrene. While some bacteria will quickly overwhelm your plant, others will slowly ravish your plant. Still, the University of Maine Cooperative Extension explains that crown gall disease can infect more than 140 genera of plants and trees.
Numerous others who attended the convention were hospitalized and struggled for their lives. GPI also causes physical changesa€”slurred speech, tremors of the lips and tongue, pupils that dona€™t react to light, and inability to control muscles or difficulty with muscle coordination.


The bacteria are still present in the body during this stage and are beginning to attack major organs and tissues in the body. This stage of syphilis is what caused people to be admitted into insane asylums in the 19th century.
Later symptoms include abdominal pain, a rash that may not be present on everyone infected, joint pain and diarrhea. It enters the natural openings of the plant through its twigs and branches and is often transported by insect and honey bee bites.
Prior to the discovery of the antibiotic in the late 1940s, the fatality rate was 30% and is currently around 3%-5%. However, bacterial diseases do take advantage of your plant’s natural state, entering the plant through its natural and man-made wounds and opening, such as with pruning cuts, cracks and stomata.
Bacterial leaf spot is a common nuisance of citrus and stone fruit trees and vegetables, as well as other indoor and outdoor foliage plants. As the galls age, they develop into hardened, discolored galls that eventually slough off to make room for new, secondary galls.
Trees and plants that are infected with fire blight will display tan-colored, bacterial ooze near the points of infection. These formations inhibit the plant’s ability to transport nutrients and water throughout the plant. The University of California explains that the foliage and flowers of the plant are generally first to show signs of infection.
However, the potential for bacterial leaf spot can be reduced by keeping the area free of decomposing debris and watering your plants at soil level. This lack of transport results in the plant’s loss of vigor which is also accompanied by growth stunt and branch and twig dieback. Planet Natural explains that the spread of bacterial leaf spot can be controlled with a copper-based fungicidal spray if applied at first signs of infection. Crown gall disease is a soil-borne bacterial disease for which there is no cure and the disease can thrive in the soil for several years without a host.
Unlike many diseases, vigorously growing trees are more susceptible to fatal infections than slow-growing ones. The University of California explains that is because the spread of fire blight is directly related to the growth of the tree. Fire blight can be controlled by pruning away the diseased and infected areas of the plant.
The pruning should be completed with sharp, sterile pruning shears that are sterilized between each cut. The potential for fire blight infections and repeat infections can be reduced by applying a copper-based fungicidal spread several times throughout the year.
