Caprylate-thallous agar medium for selectively isolating Serratia and its utility in the clinical laboratory
CT agar compares favorably with, or in some cases is an improvement over, other selective media which have been recommended for isolating Serratia and could be quite useful in ecological surveys, especially those related to hospital-acquired infections. Expand
Light and electron microscopical study of a bacterial parasite from the cyst nematode, Heterodera glycines.
The results of the cross- inoculation studies and differences in the fine structure of the cup-shaped sporangia suggest that CNP should be assigned to a new species within the genus Pasteuria. Expand
Enzymatic Degradation of Polygalacturonic Acid by Yersinia and Klebsiella Species in Relation to Clinical Laboratory Procedures
Clinical and environmental strains of Yerinia enterocolitica, Yersinia pseudotuberculosis, and Klebsiella pneumoniae "Oxytocum" showed detectable, albeit generally weak, ability to digest polygalacturonic (pectic) acid, which has a bearing on clinical laboratory procedures suitable for detecting their pectolytic activity.

Reactivity of alkali-soluble, water-soluble cell wall antigen of Coccidioides immitis with anti-Coccidioides immunoglobulin M precipitin antibody
The finding that C-ASWS extracts are reactive with IgM tube precipitin antibody and are antigenically identical to antigen 2 in CDN suggests that antigen 2 is the biologically active component of CDN in tube precip itin assays. Expand
Life cycle of a budding and appendaged bacterium belonging to morphotype IV of theBlastocaulis-Planctomyces group
Transmission electron microscopy was employed to determine ultrastructural details regarding the single ensheathed flagellum, the polarly distributed crateriform structures and numerous pili, the excreted holdfast, the multifibrillar major appendage (a fascicle), and daughter cell (bud) formation.

Ultrastructure and composition of conidial wall fractions ofCoccidioides immitis
Ease of isolation and consistency of the morphological, chemical, and immunological features of each wall fraction demonstrated here are prerequisites for ultimate characterization and purification of clinically relevant antigens from the wall of the infectious propagule. Expand
The first demonstration of transformation (Griffith, 1928) was concerned with type-specific capsular polysaccharides of pneumococci. Such transformations of capsular types usually are accompanied byExpand
