Oxygen levels are key to understanding "Anaerobic" protozoan pathogens with micro-aerophilic lifestyles.

Publications abound on the physiology, biochemistry and molecular biology of "anaerobic" protozoal parasites as usually grown under "anaerobic" culture conditions. The media routinely used are poised at low redox potentials using techniques that remove O to "undetectable" levels in sealed containers. However there is growing understanding that these culture conditions do not faithfully resemble the O environments these organisms inhabit.

Save Thousands of Lives Every Year: Resuscitate the Peer Review Privilege.

Doctors make mistakes--preventable medical mistakes--that kill or seriously injure patients. The best way to reduce these preventable errors is through a medical peer review process typically referred to as a "morbidity and mortality conference." However, over the past twenty years, federal and state courts, state legislatures, and state voters have effectively gutted the morbidity and mortality conference (M+M) as a remedial and preventative tool, resulting in tens of thousands of unnecessary deaths every year.

Efficacy of various pasteurization time-temperature conditions in combination with homogenization on inactivation of Mycobacterium avium subsp. paratuberculosis in milk.

The effect of various pasteurization time-temperature conditions with and without homogenization on the viability of Mycobacterium avium subsp. paratuberculosis was investigated using a pilot-scale commercial high-temperature, short-time (HTST) pasteurizer and raw milk spiked with 10(1) to 10(5) M. avium subsp.

Direct interface of chemistry to microbiological systems: membrane inlet mass spectrometry.

Direct measurement of dissolved gases and low molecular weight volatiles through permeable membranes (e.g. 50-microm-thick silicone rubber), provides an invaluable tool for the investigation of the activities of microorganisms in the laboratory and in their natural environments.
