The binding of 125I-labeled muscle tropomyosin to Acanthamoeba and muscle actin was studied by ultracentrifugation and by the effect of tropomyosin on the actin-activated muscle heavy meromyosin ATPase activity. Binding of muscle tropomyosin to Acanthamoeba actin was much weaker than its binding to muscle actin. For example, at 5 mM MgCl2, 2 mM ATP, and 5 micronM actin, tropomyosin bound strong...

Acanthamoeba keratitis is a vision- threatening infection and the most important risk factors are contact lenses Characteristic symptoms include disproportionately severe ocular pain, epithelial ulcer, ring stromal infiltrate and resistance to antimicrobial treatment. The aim is to report the first cases of Acanthamoeba keratitis in Yazd in a retrospective study confirmed on histopathological ...

Acanthamoeba keratitis (AK) is a sight-threating infection of the cornea that mostly affects contact lens wearers. Until now, AK treatment remains very difficult due to the existence of a highly resistant cyst stage in the life cycle of Acanthamoeba which is extremely resistant to most of the available anti-amoebic compounds. Moreover, current treatment of AK is usually based in the combination...

Free-living amoebas (AVLs), such as Acanthamoeba, Naegleria, Balamuthia, and Vermamoeba, have been identified in both natural man-made settings, hot springs spas. Naegleria fowleri causes primary amebic meningoencephalitis, while Acanthamoeba Balamuthia cause chronic granulomatous encephalitis. can also skin lesions amoebic keratitis. This study aimed to identify the presence of these protozoa ...

conclusions the results of the present study revealed that soil resources of these areas were contaminated with opportunistic amoebas such as acanthamoeba and hartmannella spp. and this may lead to severe diseases in high-risk people, such as immunocompromised patients. background free-living amoebas are very abundant in nature, especially in water and soil. some species of amoebas cause seriou...

Acanthamoeba keratitis (AK) is a sight-threatening infection of the cornea disease that often presents with a lengthy and not fully effective treatment. Current therapeutic options against Acanthamoeba are not very effective against the cyst. Calibrated trophozoite/cyst suspension was incubated with the same volume of serial dilutions of the Trigonella foenum graecum aqueous extract (200, 250, ...

Background and Aims: Amoebae of the genus Acanthamoeba are unicellular amphizoic opportunistic pathogens that may cause fatal granulomatous encephalitis, eye keratitis, amebic pneumonitis and skin nodules as well as abscesses in humans and animals. Acanthamoeba keratitis is caused by trauma to the eye, contaminated cleaning solutions and the use of contact lenses. The aim of the present study w...
