RESUMEN
The titers of antibodies to the benzylpenicilloyl antigenic determinant are increased with specific antiserum to immunoglobulin D, as shown by the enhancement method. This increase in titer is blocked by purified immunoglobulins D protein but not by immunoglobulins of the other four classes.

During a two-year period, 1,892 patients underwent biliary tract surgery at the Mayo Clinic. Both aerobic and anaerobic bile cultures were performed in 371 patients and 253 of these were positive. Anaerobes were isolated from 100 patients, although only twice in pure culture. Only aerobes grew from cultures from 153 patients. One hundred cases of biliary tract infections involving anaerobes and an equal number involving aerobes only were reviewed in order to determine their clinical characteristics. Prominent features of anaerobic bactibilia included (1) a history of complex, multiple, biliary tract surgeries often involving biliary-intestinal anastomoses and common bile duct manipulation, (2) severe symptoms, (3) high incidence of postoperative infectious complications, especially wound infections. Further analysis of anaerobic biliary infections suggested that Bacteroides fragilis was more often associated with serious pathologic conditions of the biliary tract than was Clostridium.

The neurologic complications of varicella-zoster (VZ) virus infections are manifested as zoster with or without CNS involvement, encephalomyelitis, or ocular involvement. Usually the association of VZ virus in these conditions has been determined by finding VZ antibodies in the serum. In a few instances, VZ antibodies have been detected in the CSF. We report two cases of VZ virus infection followed by neurologic complications involving the CNS in which VZ antibodies were present in the CSF. These two cases underscore the need and value of determining the presence of VZ antibodies in the CSF in certain instances.
