Strains of Streptococcus salivarius were screened by negative staining for the presence of surface structures. Two structural subgroups were found, carrying either fibrils or fimbriae, projecting from the cell surface. Eight strains carried a very dense peritrichous array of fibrils of two distinct lengths. Long fibrils had an average length of 175 nm, and(More)
We screened 36 strains of Streptococcus sanguis biotype I and 8 strains of S. sanguis biotype II for the presence of surface structures and for their ability to coaggregate with Actinomyces viscosus, Actinomyces naeslundii, and Fusobacterium nucleatum. Negative staining under an electron microscope revealed detectable surface structures on all S. sanguis(More)
Microsporidia are an emerging cause of significant disease, particularly in the immunocompromised host. Until recently, the diagnosis of enteric infections has required invasive sampling, the use of expensive technology, and considerable technological expertise. The purpose of the present study was to examine three modifications to the processing of fecal(More)
A new microtechnique has been developed for the detection of leptospiral antibodies in serum by the microscopic agglutination test. The test was set up in a microtiter transfer plate held in a transfer plate holder, resting on a transfer plate cover. Live leptospiral antigen was added and a second transfer plate cover was placed over the transfer plate(More)
We describe a fluorescent determination of total cholesterol in serum for which the accuracy and precision are comparable to that for the method of Abell-Kendall, a method of generally accepted accuracy. By the use of quality reagents and the rigorous exclusion of water, the strong fluorophor that develops on reacting concentrated sulfuric acid with(More)
Cancer is a leading cause of mortality and morbidity in the USA (Hoyert et al. 2012). Additionally, cancer health disparities (incidence, morbidity, mortality) exist in the USA despite notable progress in diagnosis and treatment (Ward et al. 2004). Racial/ethnic minorities, low socioeconomically disadvantaged populations, and persons living in rural areas(More)
A liquid chromatographic method for determination of bendiocarb in technical materials and wettable powders was tested by 12 collaborators. Bendiocarb is dissolved in acetonitrile containing 0.1% propiophenone as internal standard. This solution is analyzed on a liquid chromatograph utilizing a reverse phase (C18) column. The compound is detected at 254 nm(More)
