Acanthamoeba belonging to T3, T4, and T11: genotypes isolated from air-conditioning units in Santiago, Chile. | LitMetric

AI Article Synopsis

  • Acanthamoeba, a type of free-living amoeba, is commonly found in various environments, including air-conditioning units.
  • Researchers in Chile collected air and water samples from air-conditioning systems to check for the presence of Acanthamoeba and successfully identified T3, T4, and T11 genotypes for the first time in these systems.
  • The findings highlight the need for increased awareness among the public and health professionals in Chile about the potential health risks posed by Acanthamoeba strains.

Article Abstract

Free-living amoebae (FLA) of the genus Acanthamoeba are widely distributed in the environment, in the air, soil, and water, and have also been isolated from air-conditioning units. The objective of this work was to investigate the presence of this genus of FLA in the air-conditioning equipment at the Institute of Public Health of Chile in Santiago, Chile. Water and air samples were collected from air-conditioning systems and were checked for the presence of Acanthamoeba spp. Positive samples were further classified at the genotype level after sequencing the highly variable diagnostic fragment 3 (DF3) region of the 18S rRNA gene. This is the first report of the T3, T4, and T11 genotypes of Acanthamoeba in air-conditioning units from Chile. Overall, the widespread distribution of potentially pathogenic Acanthamoeba strains in the studied source demands more awareness within the public and health professionals in Chile as this pathogen is emerging as a risk for human health worldwide.
