Substances used on inanimate objects that destroy harmful microorganisms or inhibit their activity. Disinfectants are classed as complete, destroying SPORES as well as vegetative forms of microorganisms, or incomplete, destroying only vegetative forms of the organisms. They are distinguished from ANTISEPTICS, which are local anti-infective agents used on humans and other animals. (From Hawley's Condensed Chemical Dictionary, 11th ed)

- Free-living amoebae like Acanthamoeba are ubiquitous in soil and water environments, in which they prey on bacteria, thereby controlling bacterial populations and enhancing nutrient recycling ( 1 , 2 ). (asm.org)
- We compared the growth of Mycobacterium avium , a human pathogen associated with domestic water supplies, in coculture with the free-living amoeba Acanthamoeba polyphaga with the growth of M. avium when it was separated from amoebae by a 0.1-μm-pore-size polycarbonate membrane (in a parachamber). (asm.org)
- Meanwhile, it is well-documented that L. pneumophila multiplies within amoebae and that Acanthamoeba cysts are able to protect legionellae from certain disinfection procedures ( 17 , 22 ). (asm.org)
- This new virus was then called Acanthamoeba polyphaga mimivirus (APMV), due its ability to infect the free-living amoebae Acanthamoeba polyphaga sp. (biomedcentral.com)
- More recently, it has been shown that M. avium survives intracellularly within Acanthamoeba castellanii and interferes with the fusion of the lysosomal and parasitophoric vacuoles. (asm.org)
- L. pneumophila is especially challenging to control because it establishes and grows as part of the native plumbing microbiota, even under oligotrophic conditions and in the presence of disinfectants. (biomedcentral.com)
- While L. pneumophila resided within the cysts, M. avium was found within the outer walls of the double-walled cysts of A. polyphaga . (asm.org)
- In contrast to L. pneumophila , M. avium exhibits saprophytic growth on products secreted by Acanthamoeba cells. (asm.org)
- At that time, Gram-positive cocci that were visualized by light microscopy inside Acanthamoeba polyphaga cells were named Bradford coccus. (biomedcentral.com)
- High concentrations of virus are shed in the feces 3 to 10 days before the onset of clinical symptoms with infectious virions present in stool as early as 2 to 3 weeks before, and up to 8 days after the onset of jaundice. (waterpathogens.org)
- Acanthamoeba polyphaga mimivirus (APMV) was the first known mimivirus, isolated from an amoebal co-culture present in a water sample collected from a cooling tower of a hospital in England. (biomedcentral.com)
- However, since the mycobacteria are viable in trophozoites and cysts of Acanthamoebae, they might benefit from this interaction under adverse conditions. (asm.org)
