Legionella contamination of dental-unit waters
Water samples collected from 28 dental facilities in six U.S. states were examined for the presence of Legionella pneumophila and other Legionella spp. by the PCR-gene probe, fluorescent-antibodyExpand
Purification of lipoprotein antigens of Echinococcus granulosus from sheep hydatid fluid.
A simple two-step procedure was devised for the preparation of a fraction of sheep hydatid fluid containing two major lipoprotein antigens, finding the degree of contamination by host serum proteins to be in the region of 1.6%. Expand
Ivermectin distribution in the plasma and tissues of patients infected with Onchocerca volvulus
In healthy volunteers, the plasma ivermectin distribution was similar to that in patients, and both groups showed a tendency for a second rise in plasma concentration of the drug suggestive of enterohepatic recirculation, whilst values for skin, nodular tissues, and worms were comparable. Expand
Microbial contamination of dental unit waterlines: origins and characteristics.
The medical risk of dental unit waterline contamination is most significant to immune-deficient individuals, and regulations and technological devices are emerging to manage dental water quality. Expand
Angiostrongylosis in a greyhound.
Hemorrhages, widespread in subcutaneous tissue and muscle masses and at serosal surfaces, were suggestive of the onset of the bleeding disorder that has been seen in angiostrongylosis in Europe. Expand
A clinical classification and grading system of the cutaneous changes in onchocerciasis
A clinical classification and grading system for recording the cutaneous changes of onchocerciasis is presented and it is proposed that this system be used as a standard method of description to convey clinical information between workers in all endemic areas to assist local and comparative research.

The profile of IgG and IgG subclasses of onchocerciasis patients
The status and score of skin lesions were found to have significant effect on the IgG and IgG subclasses levels (all P < 0·001), and lgG4 showed a positive correlation with the microfilarial (Mf) load (r= 0·21, P< 0·03). Expand
Microbial contamination of dental unit waterlines: short- and long-term effects of flushing.
The extensive microbial contamination of DUW in this study is consistent with that described in previous reports and the presence of hemolytic staphylococci and streptococci in water samples from lines that were supplied only from sterile water reservoirs adds to the growing evidence that part of the microbial flora in DUWLs may be derived from patients' mouths.

Antimicrobial treatment of nylon
The preparation of an antimicrobial nylon material and its properties are discussed. Biocidal cyclic N-chloramine moieties were covalently bonded to Nylon 66. These moieties, which includedExpand
Endotoxin contamination in the dental surgery.
The extent of bacterial contamination in the dental waters sampled for this investigation surpassed the levels associated with potable water, with counts in excess of 2.0x10(6) c.f.u. ml(-1) in some samples. Expand
