Human infection from plants is very rare, but it does happen.
The primary pathogen of concern is a bacteria known as Pseudomonas aeruginosa, which causes a type of soft rot in plants.
aeruginosa infections in humans can invade nearly any tissue in the human body, provided they are already weakened.
Are plant diseases harmful to humans?
In most cases, the answer is no. The fungi, bacteria, viruses, and nematodes that cause disease in plants are very different from those that cause disease in humans and other animals. Eating or touching infected plants or their parts would not likely infect us with the same pathogen that is making the plant sick.
How do plant bacteria affect humans?
Plant diseases are well known to reduce the food available to humans by ultimately interfering with crop yields. Although the fungi producing these mycotoxins infect plants but not humans, these mycotoxins can have direct effects on humans and animals, resulting in diseases and death.
Can a plant virus infect humans?
Numerous viruses infect plant, however, none of them so far is known as pathogen to animal and human beings. The findings trigger to reevaluate the dogmatic concept that plant viruses are safe to human health even though numerous viruses are consumed through various types of fresh foods and food-products.
What plants cause diseases?

What are the signs of plant disease?
A symptom of plant disease is a visible effect of disease on the plant. Symptoms may include a detectable change in color, shape or function of the plant as it responds to the pathogen. Leaf wilting is a typical symptom of verticilium wilt, caused by the fungal plant pathogens Verticillium albo-atrum and V. dahliae.
Can bacteria be infected by viruses?
Viruses Infect BacteriaWell, it turns out that most of the viruses in the world infect bacteria instead of people. Scientists call these viruses bacteriophages (which literally means “bacteria eaters”).
Are viruses alive activity?
Viruses are only active when inside a host because they can’t undergo any chemical reactions of their own outside a host cell. Viruses do not need energy but the host cells they take over need energy to reproduce the viruses.
Can plants carry viruses?
Plant viruses are viruses that affect plants. Like all other viruses, plant viruses are obligate intracellular parasites that do not have the molecular machinery to replicate without a host. Plant viruses can be pathogenic to higher plants.
Why can’t plant viruses infect humans?
Unlike animal viruses, plant viruses cannot replicate in humans or other animals, largely due to the lack of specific receptors for recognition and entry into host cells.
Are all viruses lethal?
Serious diseases such as Ebola and AIDS are also caused by viruses. Many viruses cause little or no disease and are said to be “benign”. The more harmful viruses are described as virulent. Viruses cause different diseases depending on the types of cell that they infect.
Can animal viruses infect humans?
Humans cannot be infected by plant or insect viruses, but they are susceptible to infections with viruses from other vertebrates. These are called viral zoonoses or zoonotic infections. Examples include, rabies, yellow fever and pappataci fever.
