What does this research mean for the field?

Campylobacter jejuni can infect and reside as an endosymbiont within Acanthamoeba in hospital environments, potentially serving as a protected reservoir that poses a health threat to patients. Novelty: ClaimNovelty.CONFIRMATORY. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Identify Acanthamoeba in hospital environments, determine the presence of Campylobacter jejuni endosymbionts within positive samples, and assess bacterial infection of the amoebae in vitro.

Environmental surveillance reveals Acanthamoeba harboring pathogenic Campylobacter jejuni in hospital environments, indicating potential transmission risks for vulnerable patients.

Key Points

Identify Acanthamoeba in hospital environments, determine the presence of Campylobacter jejuni endosymbionts within positive samples, and assess bacterial infection of the amoebae in vitro.
Collected 134 environmental samples consisting of water, soil, and dust from hospital environments in Markazi Province, Iran.
Identified Acanthamoeba and endosymbiotic Campylobacter jejuni using microscopic examination and PCR assays.
Evaluated the capacity of bacteria to infect amoebic hosts via in vitro cocultivation analyzed by real-time PCR.
Acanthamoeba contaminated 44.7% of sampled hospital environmental sites.
Among 42 PCR-positive Acanthamoeba isolates, 7 (16.67%) harbored Campylobacter jejuni endosymbionts.
Cocultivation confirmed that the bacteria actively penetrate and establish intracellular infection within Acanthamoeba.
