Modified procedure for pyocine typing.

Pyocine Typing of Pseudomonas Aeruginosa.

The growth-inhibitory effect of a small group of different pyocines has been used to differentiate Ps. aeruginosa isolates. A method is described which can be carried out with ordinary media and is easy for routine application. One hundred and one isolates of Ps. aeruginosa were differentiated by four pyocines into 10 pyocine patterns.

Pyocine-typing of Hospital Strains of Pseudomonas Pyocyanea.

A method of typing Pseudomonas pyocyanea is described which makes use of the property of bacteriocine production. The method was applied in an epidemiological study of Ps. pyocyanea infection in a general hospital. It was found that the majority of strains believed on epidemiological grounds to be of common origin were allotted to the same pyocine type. In the course of this study, Ps. pyocyane...

Pyocine typing of clinical strains of Pseudomonas aeruginosa.

A total of 954 clinical isolates of Pseudomonas aeruginosa were typed by their ability to produce pyocines. The strains of Pseudomonas were isolated from urines, bloods, sputa, stools, and miscellaneous infectious exudates or tissue of patients of the Mayo Clinic and four associated hospitals. About 80% of the typable strains could be grouped into three major pyocine types: A (30.9%), B (34.8%)...

Hospital Infection with Pseudomonas Pyocyanea: an Investigation by a Combined Pyocine and Serological Typing Method.

A modified Gaines procedure for spondyloptosis.

We present an illustrative case using a modification of the Gaines procedure for the surgical management of patients with spondyloptosis. It involves excision of the inferior half of the body of L5 anteriorly combined with posterior reduction and fusion.
