We report a case of acanthamoebic keratitis that occurred after minor ocular trauma in a healthy 31-year-old man. Multiple microbiological investigations failed to reveal the causative organism, which was identified as Acanthamoeba castellanii only after a corneal graft operation had been performed. A review of previously described cases reveals that this rare ocular infection tends to cause recalcitrant corneal ulcers after minor eye injuries in otherwise healthy individuals.

Introduction: Ophthalmological conditions in international travelers may be associated with low mortality but high morbidity. Eye involvement in travelers is less frequently reported than febrile, gastrointestinal and respiratory infections, but data probably represent a degree of under-notification.
Methods: an extensive narrative review of the main viral, bacterial, fungal and parasitic infections affecting the eye in travelers was performed.

Tetrazoles are five-membered ring aromatic heterocyclic molecules that consist of one carbon and four nitrogen atoms. Several tetrazole-based drugs have shown promising activities against bacteria, fungi, asthma, cancer, hypertension etc. The overall aim of this study was to determine anti-Acanthamoebic properties of tetrazoles and tetrazole-conjugated silver nanoparticles.

Pathogenic produce keratitis and fatal granulomatous amoebic encephalitis. Treatment remains problematic and often ineffective, suggesting the need for the discovery of novel compounds. For the first time, here we evaluated the effects of the anticancer drugs Irosustat and STX140 alone, as well as their nanoformulations, against via amoebicidal, excystment, cytopathogenicity, and cytotoxicity assays.

Acanthamoeba castellanii causes granulomatous amoebic encephalitis, an uncommon but severe brain infection and sight-threatening Acanthamoeba keratitis. Most of the currently used anti-amoebic treatments are not always effective, due to persistence of the cyst stage, and recurrence can occur. Here in this study we synthesize cinnamic acid and lactobionic acid-based magnetic nanoparticles (MNPs) using co-precipitation technique.

We examined the anti-acanthamoebic efficacy of green tea Camellia sinensis solvent extract (SE) or its chemical constituents against Acanthamoeba castellanii by using anti-trophozoite, anti-encystation, and anti-excystation assays. C. sinensis SE (625-5000 µg/mL) inhibited trophozoite replication within 24-72 h.
