A set of broad-range PCR primers for the 16S rRNA gene in bacteria were tested, along with three series of oligonucleotide probes to detect the PCR product. The first series of probes is broad in range and consists of a universal bacterial probe, a gram-positive probe, a Bacteroides-Flavobacterium probe, and two probes for other gram-negative species. The(More)
Two previously healthy, immunocompetent men had persistent Rochalimaea henselae bacteremia with clinical relapses after courses of antibiotics to which the isolates were ultimately demonstrated susceptible in vitro. Both had sustained tick bites prior to their illnesses, thus demonstrating an association not previously identified, although suspected. The(More)
This article reviews the health effects, treatment, prevention strategies, and international standards for hand-arm vibration syndrome (HAVS). It draws attention to the proposed International Standards Organization (ISO) 1998 revision requirement to base the assessment of vibration on the root-sum-of-squares for all directions rather than the dominant(More)
A total of 143 miners, 6 ex-miners, and 42 referents from five mines in northern Ontario were examined with a cold provocation test. The skin temperatures, measured by thermocouples at the tips of the fingers and thumbs were recorded at 5-s intervals throughout the immersion in cold water (10 degrees C) for 10 min and during the recovery period. The finger(More)
Although rates of listeriosis are low in comparison to other foodborne pathogenic illness, listeriosis poses a significant risk to human health as the invasive form can have a mortality rate as high as 30%. Food processors, especially those who produce ready-to-eat (RTE) products, need to be vigilant against Listeria monocytogenes, the causative pathogen of(More)
BACKGROUND The American Heart Association (AHA) standard for delivering thrombolytic therapy to chest pain patients is 30 to 60 minutes after patient presentation to the emergency department. Three acute care hospitals in an integrated health system in northern California shortened the time of administration of thrombolytic agents to appropriate patients(More)
European Regulation (EC) No. 2073/2005 lays down the microbiological criteria for certain microorganisms in foods and the implementing rules to be complied with by food business operators (FBOs) in Europe when implementing general and specific hygiene measures. In relation to Listeria monocytogenes, this regulation covers primarily ready-to-eat (RTE) food(More)
The standards for hand-arm vibration have evolved from research studies in the late 1960s and were based on discomfort and tolerance levels. The lower frequencies were more intolerant and were weighted accordingly. The vascular and neurologic components of the hand-arm vibration syndrome may develop independently, and recent epidemiologic studies have shown(More)
A better understanding of the origin and natural reservoirs of resistance determinants is fundamental to efficiently tackle antibiotic resistance. This paper reports the identification of a novel 5.8 kb erythromycin resistance plasmid, from Bacillus sp. HS24 isolated from the marine sponge Haliclona simulans. pBHS24B has a mosaic structure and carries the(More)
