Quantitative bacteriology of the vaginal flora in vaginitis.

Vaginal flora was studied quantitatively in 29 sexually active women, 16 to 33 years of age, to define the role of C. vaginale in vaginitis. Seventeen were asymptomatic and 12 complained of symptoms of vaginitis. Seven asymptomatic women had scant secretions: four of these seven had C. vaginale at log10 6 to 9 CFU per milliliter, none of whom had "clue" cells; none had trichomonas or candida; six had lactobacilli at log10 7 to 9.7 per milliliter; only one had Bacteroidaceae at greater than log10 5 per milliliter. Ten asymptomatic women had easily collectable secretions; eight of 10 had C. vaginale at log10 6.5 to 9.6 per milliliter, three of whom had "clue" cells; four had trichomonas and none candida; nine had Lactobacilli at log10 7 to 9.3 per milliliter; four had Bacteroidaceae at greater than log10 5 per milliliter. Twelve had vaginitis: five of 12 had C. vaginale at log10 7.9 to 11 per milliliter, one of whom had "clue" cells; nine had either trichomonas or candida or both and three had no pathogen, including C. vaginale; 10 had Lactobacilli at log10 7 to 10 per milliliter; six had Bacteriodaceae at greater than log10 5 per milliliter. Three had "clue" cells in absence of C. vaginale.

A comparative study of two antibiotic regimens for the treatment of operative site infections.

This prospective study was designed to compare the relative efficacy of two antibiotic regimens for the treatment of operative site infections subsequent to pelvic operations. Patients with endomyoparametritis after delivery or pelvic cellulitis subsequent to hysterectomy were randomized to treatment with the combination of penicillin-gentamicin or the single agent cefoxitin. Seventeen of the 26 patients (65%) with endomyoparametritis who were treated with penicillin-gentamicin were cured by antibiotic therapy alone, in comparison to 15 of 23 (65%) patients treated with cefoxitin. Fifty-eight percent of the patients with pelvic cellulitis who were treated with penicillin-gentamicin responded favorably, in comparison to 50% of the patients treated with cefoxitin. None of these differences was statistically significant. In this study, neither antibiotic regimen provided satisfactory initial treatment for surgically induced soft tissue pelvic infection. Moreover, 11 of the 28 patients with treatment failures (40%) developed serious sequelae of their primary infection.

Viability of lyophilized anaerobes in two media.

Viability of 15 species of anaerobes was followed after freeze-drying and storage for 1 year. Organisms maintained in a 12% sucrose concentration in chopped meat carbohydrate broth survived longer and maintained higher viability counts than those organisms in double-strength skim milk.

Isolation of anaerobic organisms from kidney in serious renal infections.

We have studied 45 patients who underwent nephrectomy owing to unilateral renal sepsis for anaerobic and aerobic bacterial growth in the urine and kidney. Anaerobic organisms were recovered from 11 patients: 10 had positive kidney cultures, and only 1 had positive kidney and urine cultures. There was a distinct relationship between anaerobic infection of the kidney and urinary tract obstruction; 44 per cent of the obstructed kidneys yielded anaerobic organisms versus only 11 per cent of the unobstructed kidneys. Bacteroides fragilis was the anaerobic organism most often cultured. It is suggested that cultures for anaerobic organisms be performed together with aerobic cultures in patients with symptomatic upper urinary tract infections associated with urinary obstruction. In patients in whom anaerobic infection is suspected, in spite of negative anaerobic cultures, antibiotic treatment for anaerobes should be added to the existing therapeutic measures.

Anaerobic bacteria in jaw cysts.

The bacterial flora of the fluid content of 54 cysts of the jaws with a history suggestive of infection were studied. Forty-seven of these cysts were subsequently considered to be infected and from 78.6% of these, positive bacterial cultures were developed. Of the bacterial strains 89.2% were anaerobes and only 10.8% were pure aerobes or facultative anaerobes. Microorganisms isolated from each specimen ranged from 1 to 4 bacterial species. Gram positive anaerobic cocci revealed to be the most frequent bacterial group (36.9%), followed by Gram negative anaerobic rods (29.8%), Gram positive aerobic cocci being the third most common group of the isolates (19.0%). Antibiotic sensitivity tests of the isolated anaerobic cocci to a group of nine antibiotics revealed chloramphenicol and minocycline as the most effective. All anaerobic rods tested, were sensitive to metronidazole.

Anaerobic microflora of the vagina in children.

Vaginal cultures from 25 healthy girls from two months to 15 years of age were examined for aerobic, facultatively anaerobic, and obligately anaerobic bacteria. An average of 8.7 species (3.7 aerobic and facultatively anaerobic species; 5.3 obligately anaerobic species) were isolated from these cultures. Staphylococcus epidermidis (21), diphtheroids (20), bacteroides (19), peptococci (19), peptostreptococci (14), and Bacteroides melaninogenicus (14) were most prevalent organisms.

Omental pedicle graft in the management of infected ascending aortic prostheses.

Two patients had mediastinal infections with chronic draining sinus tracts that involved a vascular prosthesis in the ascending aorta. In 1 patient, a false mycotic aneurysm developed and in the other, a beginning rupture of the proximal suture line. In both patients, the infection was cured by replacing the infected aortic prosthesis combined with wrapping the new prosthesis with a pedicled omental graft. An omental graft was used to protect the vascular prosthesis and minimize the risk of recurrent infection.

The structural organization of the PsaC protein in Photosystem I from single crystal EPR and X-ray crystallographic studies.

In Photosystem I (PS I) the terminal electron acceptors, FA and FB, are iron-sulfur (4Fe-4S) centers, which are bound to the stromal subunit PsaC. The orientation of PsaC is determined relative to the whole PS I complex (see Schubert, W.-D. et al. (1995) in From Light to Biosphere (Mathis, P. ed.), Vol. II, pp. 3-10, Kluwer) from which a molecular model for the structure of PsaC within PS I is derived. Two strategies are followed: (i) PS I single crystal EPR data on the orientation of the g tensors of both FA- and FB- relative to each other and relative to the crystal axes (see preceding paper) are used in conjunction with the central structural part of the bacterial 2 [Fe4S4] ferredoxins, the cysteine binding motifs of which are known to be homologous to those of PsaC; (ii) the same core structure is fitted into the intermediate resolution electron density map of PS I. The PsaC orientation obtained both ways agree well. The local twofold symmetry axis inherent to the ferredoxin model leaves a twofold ambiguity in the structural conclusion. Deviations from this C2-symmetry in the amino acid sequence of PsaC are analyzed with respect to observable properties which would resolve the remaining structural ambiguity. Arguments both for and against FA being the distal iron-sulfur center (to FX) are discussed.
