A HIGHLY RESISTANT THERMOPHILIC ORGANISM

Ultrastructure of an extremely thermophilic acidophilic micro-organism.

A thermoacidophilic micro-organism, isolated from volcanic hot springs near Naples, was cultivated in vitro, and examined by electron microscopy in sections and after negative staining. The cells were almost spherical, with a diameter of about 0.7 to 1.0 mum. Their morphology was very primitive: the protoplasm was composed only of ground cytoplasm, ribosomes, and randomly distributed DNA strand...

A Highly Stable Adenosine Triphosphatase from a Thermophilic Bacterium

1. A highly stable ATPase (TF,) was purified to a monodispersed state from the membranes of a thermophilic bacterium PS3. Its molecular weight was 380,000, and it was composed of five subunits cy, p, y, a’, and 6 with molecular weights of 56,000, 53,000, 32,000, 15,500, and 11,000, respectively. 2. TF, was stable against dissociating agents such as 5.5 M urea and 4.0 M LiCl, organic solvents, s...

Multidrug Resistant organism Repository and Surveillance Network

Fatal Naegleria fowleri infection acquired in Minnesota: possible expanded range of a deadly thermophilic organism.

BACKGROUND Primary amebic meningoencephalitis (PAM), caused by the free-living ameba Naegleria fowleri, has historically been associated with warm freshwater exposures at lower latitudes of the United States. In August 2010, a Minnesota resident, aged 7 years, died of rapidly progressive meningoencephalitis after local freshwater exposures, with no history of travel outside the state. PAM was s...

Mapping Laboratory Reports to Illinois’ Extensively Drug-Resistant Organism Registry

Introduction CRE are drug-resistant bacteria that have a mortality rate of up to 50% in those infected1. Several clusters of CRE have been detected in Illinois, often in long-term acute care hospitals2. In response Illinois created the XDRO registry, a mandatory reporting system designed to aid inter-facility communication concerning CRE. Despite being a high priority for control in the US, the...
