Veterinary antibiotics and plant physiology: An overview

Area of Science:

• Environmental Science
• Plant Physiology
• Agricultural Science

Background:

• Antibiotics promote animal growth but are incompletely absorbed, leading to environmental excretion.
• Animal excrement used in agriculture is a primary route for antibiotic entry into ecosystems.
• Plants are exposed to antibiotics via contaminated soil and irrigation water, potentially causing phytotoxicity.

Purpose of the Study:

• To provide an overview of plant physiological alterations due to veterinary antibiotic exposure.
• To focus on antibiotic absorption, accumulation, and their effects on plant metabolism.
• To highlight impacts on germination and plant establishment in contaminated environments.

Main Methods:

• Literature review of existing studies on antibiotic phytotoxicity.
• Analysis of antibiotic absorption and accumulation in plants.
• Examination of effects on primary metabolic processes (photosynthesis, respiration, nitrogen assimilation) and oxidative metabolism.
• Review of impacts on plant germination and establishment.

Main Results:

• Antibiotics can be absorbed and accumulate in plant tissues.
• Observed phytotoxic effects include alterations in photosynthesis, respiration, and nitrogen assimilation.
• Antibiotic contamination can negatively affect plant germination and early development.
• Different antibiotics exhibit varying degrees of phytotoxicity.

Conclusions:

• Environmental exposure to veterinary antibiotics poses risks to plant health and agricultural yields.
• Understanding antibiotic uptake and metabolic effects is crucial for assessing phytotoxicity.
• Further research is needed to fully elucidate the mechanisms of antibiotic phytotoxicity and develop mitigation strategies.
