Summary
Plant bacterial pathogens transmitted by hemipteran vectors threaten agriculture. This review details molecular interactions, adhesion, invasion, proliferation, and transmission routes of these bacteria within insect vectors like leafhoppers and psyllids.
Area of Science:
- Agricultural Entomology
- Plant Pathology
- Microbial Ecology
Background:
- Hemipteran-borne plant bacterial pathogens cause significant global agricultural losses.
- Understanding molecular mechanisms of circulative bacterial transmission by insects is crucial but limited.
Approach:
- This review synthesizes current knowledge on bacterial interactions within insect vectors.
- It examines pathogen adhesion, invasion, proliferation, and transmission routes.
Key Points:
- Molecular factors enabling phloem-limited bacteria to establish relationships with leafhopper and psyllid vectors are highlighted.
- Bacterial strategies for navigating and multiplying within insect hemolymph and tissues are discussed.
Conclusions:
- Elucidating pathogen-vector molecular dynamics is essential for developing effective disease management strategies.
- This knowledge will aid in controlling economically damaging vector-borne bacterial diseases in crops.

2.9K
Intracellular bacteria and viruses often comprise a group of highly infectious pathogens that can cause several diseases. Bacterial pathogens include those belonging to the genus Rickettsia responsible for conditions such as rocky mountain spotted fever and the Mediterranean spotted fever; Chlamydia, a genus responsible for a sexually transmitted disease; Coxiella burnetii, an agent responsible for Q fever. Viral pathogens include vaccinia—a poxvirus, and herpes simplex virus—a...

Fimbriae and pili are specialized bacterial surface structures that play pivotal roles in adhesion, genetic exchange, and motility. Composed primarily of pilin protein, these hairlike appendages are crucial for bacterial survival and pathogenicity in various environments.Fimbriae: Adhesion and PathogenicityFimbriae are fine, filamentous structures measuring 2–10 nanometers in diameter and are densely distributed on the bacterial cell surface. They facilitate bacterial adhesion to abiotic...

01:20Infection
8.4K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...
