Antibiotic Resistance Genes in Agricultural Soils: A Comprehensive Review of the Hidden Crisis and Exploring Control Strategies

Antibiotics used in farming and medicine are creating resistant bacteria that accumulate in soil, threatening food safety and human health through the food chain. This review explains how these resistant genes spread through soil microorganisms and presents practical solutions including special soil treatments, chemical processes, and beneficial microorganisms to reduce the problem. The authors emphasize the need for stricter regulations on antibiotic use in agriculture and better management of farm manure to protect both soil health and public health.

Arbuscular mycorrhiza suppresses microbial abundance, and particularly that of ammonia oxidizing bacteria, in agricultural soils

This study examined how beneficial fungal partners of plants (arbuscular mycorrhizal fungi) affect soil bacteria that convert ammonia to nitrate. Using 50 different soils from Czech agricultural fields, researchers found that these fungi suppress ammonia-oxidizing bacteria, but surprisingly this happens even when ammonia levels in soil are high. The findings suggest the relationship between these microorganisms is more complex than simple competition for nutrients.
