Comparison of four hippurate hydrolysis methods for identification of thermophilic Campylobacter spp.

The test for hippurate hydrolysis is critical for separation of Campylobacter jejuni and C. coli strains. Glycine and benzoic acid are formed when hippurate is hydrolyzed by C. jejuni. The test used in most laboratories is one of several variations of the ninhydrin tube test described by Hwang and Ederer (M. Hwang and G. M. Ederer, J. Clin. Microbiol. 1:114-115, 1975) for detection of glycine. We evaluated three modifications of the Hwang and Ederer method and the gas-liquid chromatographic (GLC) method described by Kodaka et al. (H. Kodaka, G. L. Lombard, and V. R. Dowell, Jr., J. Clin. Microbiol. 16:962-964, 1982) for detecting benzoic acid. Campylobacter strains comprised 22 C. jejuni, 11 C. coli, and 8 C. laridis strains. The species identification of each strain was confirmed by DNA relatedness. All strains of C. jejuni were positive and all strains of C. coli and C. laridis were negative by the GLC method for detecting hippurate hydrolysis, whereas three strains of C. jejuni gave negative or variable results in the tube tests. The GLC method is more sensitive than the tube methods for detecting hippurate hydrolysis and should be used on cultures yielding variable or questionable test results.

A case of progressive supranuclear palsy with fibrillary gliosis of the midbrain and pontine reticular formation.

An autopsy case of progressive supranuclear palsy with onset at age 53 and a clinical course of 7 years is reported. The clinico-pathological characteristics of the case were as follows: Fibrillary gliosis of the midbrain and pontine reticular formation corresponded clinically to personality changes: The patient had formerly been irascible and became extremely mild-mannered. He showed lack of spontaneity and initiative and slowing of thought processes, taking him longer than normal to find words and ideas. Gliosis of the nucleus ventralis lateralis of the thalamus was secondary to the degeneration of the cerebellar dentate nucleus and the globus pallidus from which they receive fibers. Neurofibrillary tangles were found in the cerebral cortex.
