Borreliosis (pathogen Borrelia recurrentis)

It is important to clarify that Borrelia recurrentis is not a plant disease agent. This microorganism is a spirochete bacterium responsible for louse-borne relapsing fever in humans. It does not infect, colonize, or affect any agricultural crops, horticultural plants, or forestry species in any way.

The biology of Borrelia recurrentis is strictly adapted to human hosts and specific insect vectors like body lice. It lacks the enzymatic pathways and physiological mechanisms required to penetrate plant cell walls or utilize plant metabolites for survival. Therefore, it has no impact on the development, physiology, or health of vegetation in agricultural or wild environments.

Within the field of agronomy and plant pathology, this organism is not categorized as a plant pathogen. There are no known signs of plant damage, such as leaf spots, blight, wilting, or root rots, caused by Borrelia recurrentis. It is not listed as a quarantine object in any national or international agricultural legislation regarding plant health.

Control measures, including the application of chemical pesticides or biological control agents used in farming, are completely ineffective and unnecessary against Borrelia recurrentis as it does not participate in the crop ecosystem. Agronomic protocols for disease management focus on true phytopathogens such as bacteria from the genera Pseudomonas, Erwinia, or Xanthomonas.

For agricultural specialists, it is essential to distinguish between pathogens of humans and pathogens of plants to avoid confusion in diagnostic and scouting activities. The presence of this bacterium is a matter of public health rather than agricultural science. Growers should focus their efforts on managing pests and diseases that actually threaten the yield and quality of their produce.
