A 42-year-old man had an infected ulcerated lesion of the anterior aspect of the right lower extremity. Vibrio alginolyticus was twice isolated from the lesion. Emphasis is placed on the clinical and laboratory characteristics of this organism and its differentiation from other halophilic vibrios.
Intrauterine specimens were obtained from 22 patients with endometritis and 24 control patients following cesarean section by using both a new protected swab and a standard anaerobic swab. The protected swab improved the value of the direct smear and Gram stain, resulted in fewer false-positive cultures, better defined endometrial flora in patients with endometritis, and permitted major savings in laboratory personnel time and materials.
A protocol is presented for the cultural processing of stool specimens. Flow diagrams were developed which allow all stool cultures to be processed in a consistent and efficient manner. Criteria have been established to indicate when definitive identification and antimicrobial susceptibility testing are required. A review of the food-poisoning syndrome and infective gastrointestinal disease due to bacterial agents is included.
A protocol is presented for the processing of clean voided urine specimens, indwelling and nonindwelling catheter specimens, and special specimens, e.g., suprapubic aspirations, ureteral and kidney specimens, etc. Flow diagrams were developed which allow all urine cultures to be processed in a consistent and efficient manner. Criteria have been established to indicate when definitive identification and antimicrobial susceptibility testing are necessary.
