During a six-month period, 600 gynecological samples were collected from 585 women with typical herpes lesions, women with non-herpes symptoms (ie, vaginitis, moniliasis, trichomoniasis, etc), and normal women seen at the student health center gynecological clinic and processed for herpes simplex virus (HSV) isolation. From these specimens, 29 samples from 25 of the 585 women (4.3%) were positive for HSV. When these isolates were typed using plaque diameter in chick cells, heat stability of viral thymidine kinase (T.K.), and restriction endonuclease patterns it was found that 18 samples (15 patients or 60%) were HSV-2 and 11 samples (10 patients or 40%) were HSV-1. Inapparent HSV infections constituted 20.0% of the virologically confirmed samples (5 of 25 patients) and represented 0.9% of the total patients studied (5 of 585). The inapparent infections were about equally divided between the two HSV types (2 were HSV-2 and 3 were HSV-1), and 4 of 5 occurred in the presence of clinically diagnosed monilia.

Two herpesvirus isolates from goats are known which cause afflictions of the digestive tract in kids and, in some cases, abortion. An antigenic relationship of these goat herpesviruses with infectious bovine rhinotracheitis/infectious pustular vulvo-vaginitis virus (bovid herpesvirus 1, BHV-1) was reported and because of the species-specific pathogenicity, the goat isolates were named caprine herpesvirus 1. In this report the two isolates are further characterized and compared with BHV-1. Although the caprine herpesviruses share many biological and physicochemical properties with BHV-1, they can be differentiated from the bovine viruses with respect to growth cycle, one-way cross-neutralization and, most importantly, the restriction endonuclease fragments of their DNAs. The molecular weight of the caprine herpesvirus DNA, based on electron microscopic length measurement is 90 X 10(6), similar to that of BHV-1 (95 X 10(6]. On the basis of these genomic differences, we propose that DNA restriction endonuclease patterns of the caprine herpesviruses should be designated as prototypic of bovid herpesvirus 6 (BHV-6).

Saccharomyces cerevisiae is a ubiquitous, ascomycetous yeast, and vaginitis caused by this organism has been reported only very rarely. The aim of the present investigation was to assess the epidemiological relatedness of a group of vaginal and commercial S. cerevisiae isolates by a previously reported genetic typing method, which divided the isolates into two broad groups with numerous subtypes. Nineteen S. cerevisiae isolates obtained from patients suffering from vaginitis and four isolates from commercial products in the same city were analyzed. The cellular DNA from each isolate was digested with the restriction endonuclease EcoRI, and restriction fragment length polymorphisms were generated by horizontal gel electrophoresis. The results showed that although vaginal isolates did not cluster in any particular genetic subtype, multiple patients were infected with indistinguishable strains (there were nine distinct strains among 23 isolates). For two of three patients, all three with two episodes of S. cerevisiae vaginitis, different strains were isolated during the recurrence of this disease. Three other patients with indistinguishable isolates were epidemiologically related in that two were practitioners in the same clinic and the third was a patient at this clinic. We also found that one commercial strain was indistinguishable from the strain isolated from three different women at the time that they were suffering from vaginitis. The findings of the present study suggest that some S. cerevisiae strains may possess properties permitting persistence in the human host. Furthermore, person-to-person contact and the proliferation of the use of S. cerevisiae as a health-food product, in home baking, and in home brewing may be a contributing factor in human colonization and infection with this organism.
