The reduction of nitroblue tetrazolium (NBT) dye by neutrophils from 379 patients with infectious diseases and 268 controls has been examined. The mean NBT score was 29.8% (72.3% positive tests) in the 231 patients with non-tuberculous bacterial infections, 9.7% (28.1% positive tests) in the 135 patients with viral infections 5.3% (1.5% positive tests) in the controls. Positive tests were demonstrated in 1 of 7 patients with tuberculosis and in 4 of 6 with mycoplasma pneumonia. Patients with urinary tract infections or septicemia had the highest percentage of positive tests, particularly when the infections were caused by gram-negative bacteria. In acute bacterial infection, the 176 patients who had not received any antibacterial therapy prior to testing had a significantly higher mean NBT score and proportion (77.8%) of positive tests than the remaining 55 pretreated patients (54.5%). Recent antibiotic treatment seriously invalidates the NBT test results. In acute viral infection, 29 of the 38 positive tests were obtained from patients with acute hepatitis (mean score 20.0%) or infectious mononucleosis (mean score 9.3%). When evaluating the test results, special attention should be paid to patients with hepatitis. Endotoxin stimulated NBT tests disclosed normal enhancement of NBT reduction by neutrophils from the patients and the controls. Cautiously interpreted, the NBT reduction by neutrophils from the patients and the controls. Cautiously interpreted, the NBT test results may be useful as an adjunct in the differential diagnosis of major bacterial and viral infections.

Forty-eight 32-week-old meat-type females, free from Mycoplasma synoviae (Ms.) and Mycoplasma gallisepticum (Mg.) were aerosol exposed with a 24-hour broth culture of Ms. 1331 and placed in 3 pens. 16 birds per pen. Two males were placed in each of the 3 pens and used as contact birds. All birds were bled at 2, 4, 7, 10, 14, 24, 26, and 30 weeks post Ms. exposure. After the 24-week bleeding, the females were equally divided into 4 pens. All females in 2 of the pens were given a foot pad injection of 0.3 ml. of Ms. 1331 broth culture. Ms. isolation attempts were made from the trachea of all birds at 2, 14, and 24 weeks post Ms. exposure. Ms. isolation attempts were made from all eggs produced, either from the allantoic fluid and egg yolk of 17- or 18-day-old embryos, dead embryos, and infertile eggs, or from the tracheas of day-old progenies. Each day-old progeny was bled. Ms. and Mg. serum plate tests were conducted on the serums from the progeny and adult birds from each bleeding. Ms. hemagglutination-inhibition (HI) tests were conducted on the serums of the adult birds. In the Ms.-exposed birds, the geometric mean HI titer of the serums from each bleeding rose significantly over the previous bleeding. The percentages of Ms. serum plate reactions increased with length of time after Ms. exposure. There were false Mg. serum plate reactions in the early stages of Ms. infection. A foot pad challenge with a broth culture of Ms. 1331 24 weeks after Ms. exposure did not significantly increase the geometric mean HI titer over the Ms. exposed birds that did not have a Ms. foot pad challenge. Ms. was isolated from the trachea of 91.6%, 100%, and 100% of the Ms.-exposed birds at 2, 14, and 24 weeks after Ms. exposure, respectively. There were 35 Ms. isolates from 575 attempts from 17- or 18-day embryos, dead embryos, or infertile eggs, and 7 Ms. isolates from 67 attempts from the trachea of day-old progenies. All isolates were made from eggs collected from 6 through 31 days afer Ms. exposure. No isolations were made from 1760 attempts made from eggs collected from 32 through 210 days after Ms. exposure, including eggs collected from Ms. foot pad-challenged birds at 168 days after Ms. exposure. There were 312 broilers reared from eggs collected from the 22 through 24 weeks after Ms. exposure. The broilers were marketed at a federally inspected poultry processing plant. Their records showed 3 birds condemned for septicemia-toxemia, but none were condemned for air-sacculitis or synovitis. Twenty-four serums from the broilers that were positive to Ms. or Mg. serum plate tests were all negative to the Ms. and Mg. HI tests. Ms. serum plate reactors began to show up in the day-old progeny from eggs collected beginning on the 76th day after Ms. exposure. There were 16.0% (80/500) positive to the Ms. serum plate test from eggs collected from the 76 through 126 days after Ms. exposure and 14.0% (52/372) from eggs collected from the 169 through 210 days after Ms. exposure.

The term "variegated translocation mosaicism" is used to describe the repeated occurrence, within cultures of human skin fibroblasts, of a multiplicity of chromosomal rearrangements. With respect to the frequencies of such cytogenetically aberrant clones we found that they (1) were not detectable in routine diagnostic skin fibroblast cultures from 29 subjects with a wide variety of indications for biopsy; (2) were not detectable during in vitro aging of diploid strains with four normal individuals; (3) could be detected after rescue from bacterial contamination of a culture from an otherwise normal diploid male; (4) occurred with high frequencies in independent cultures from another apparently normal subject; (5) occurred with high frequencies in multiple biopsies obtained at autopsy from a patient with Werner's syndrome who died of sepsis; (6) were of pseudodiploid nature; and (7) involved a different spectrum of chromosomes in different individuals. A consistent association with mycoplasma contamination could not be made.

In a prospective study, 1156 blood specimens collected from hospitalized febrile obstetrical-gynecologic patients and neonates with suspected sepsis, were inoculated into a conventional biphasic culture medium, Castaneda S and cultures incubated aerobically. 15-24 h later the broth cultures were subcultured to specific media for detection of mycoplasmas. Genital mycoplasmas were isolated in 15 samples (taken from 8 women) and in 2 from 1 neonate. Mycoplasmas and members of the family Enterobacteriaceae were the most frequent significant bacteria isolated from adult specimens. Mycoplasma isolations were associated with either postpartum or postabortum febrile infections in women. Four of the neonates, whose mothers were infected, showed respiratory distress at birth; 1 of them had mycoplasmas in the blood. All febrile states in obstetrical or gynecological patients, and in neonates, should routinely lead to blood cultures for detection of mycoplasmas and ureaplasmas.

A 64-year-old slaughterhouse worker with advanced non-Hodgkin's lymphoma developed septicemia and pneumonia. Mycoplasma arginini, a wall-free prokaryote found in a variety of domestic animal hosts, was repeatedly isolated from blood and bronchial washings from the patient. Immunosuppression, in part caused by hypogammaglobulinemia, probably played a key role in predisposing the patient to a fatal infection. This case suggests that animal mycoplasmas should be considered in the list of infectious agents acquired by immunosuppressed hosts.

alpha-Hemolytic streptococci, variously described as cell-wall deficient (C), L form (L), thiol dependent (O), satelliting (S), pyridoxal dependent (PY), and nutritionally deficient (N), or CLOSPYN, were isolated from patients with endocarditis, brain abscess, subauricular abscess, septicemia, acute and chronic urethritis, recurrent aphthous stomatitis, and fever of undetermined origin. With the aid of satelliting, most of the strains were adapted to grow on a human Mycoplasma growth agar consisting of brain-heart infusion agar fortified with 20% human blood, yeast extract, and arginine. Selected CLOSPYN strains required extensive subculture for only partial reversion to parentallike characteristics. Four of six strains biochemically tested were judged Streptococcus morbillorum. Two were unidentifiable. The CLOSPYN form was relatively inert biochemically, but glucose was converted mainly to lactic acid, with acetic acid also present. Guanine-cytosine values were 39%-43%. Cell wall material was present by transmission electron microscopy (TEM), but its synthesis was uneven on single cells and abnormally thickened on other cells. Closely spaced, incompleted septa occurred in cell chains, which resulted in unusually long chains of flattened cells resembling on TEM a stack of checkers. Mesosomes were frequent, greatly enlarged, convoluted, and elongated. They were often sectioned as circular and laminated, with 2-5 layers. Mesosomes were in close contact with nucleoid bodies, which, in turn, were closely apposed or integral with the cytoplasmic membranes in areas of cross-wall development. Chaotic morphology typifies the group. The inclusion of urinary tract infections is new in the gamut of diseases caused by CLOSPYN streptococci.

Upon admission to Box Hill Hospital in Victoria, Australia, a 38-year old woman was pale and febrile (328.6 degrees Celsius) and had a pulse of 88 beats/minute. She had had midabdominal pain for 1 week and severe lower abdominal pain for 2 days. Her menses were heavy. Other than pain during examination, rectal and vaginal examinations were normal. She had considerable neutrophilia (leukocyte count = 21.2 x 1 billion). The X-ray revealed free fluid. Ultrasonography indicated an IUD which she had had for 10 years, a mass with small cystic areas near the right ovary, and fluid in the rectouterine pouch. The physicians suspected peritonitis and administered iv broad spectrum antibiotics (1 mg ampicillin, 80 mg gentamicin, and 500 mg metronidazole) every 8 hours. They did a laparotomy. An abscess containing much green pus, the necrotic right ovary, and the appendix, which appeared normal and later shown not to be infected, occupied the right iliac fossa. The tubes were fine. The surgeons removed the appendix and right ovary. They washed out the abdomen with saline and inserted a drain to the right iliac fossa. The woman improved immediately so the physicians stopped antibiotics 3 days after surgery. Histological tests revealed actinomycosis caused by fast-growing aerobic bacteria which is known to cause necrosis, fibrosis, and suppuration. During recovery, the physicians removed the IUD and performed dilation and curettage. Actinomyces normally just dwell in the mouth and intestines, but, in this case, probably migrated up the IUD tail after spreading from the bowel to the perineum to the vagina. The physicians suspected that the presence of Mycoplasma hominis provided the mucosal breach needed to permit actinomyces' invasion. Physicians should consider actinomycosis in acute abdominal sepsis cases with a longterm use of an IUD. They can treat it with antibiotics since Actinomyces tend to be sensitive to broad spectrum antibiotics.

Three monoclonal antibodies (MAbs) were prepared against an arthritogenic strain of Mycoplasma hominis isolated from the joint aspirates of a patient with chronic septic arthritis. Immunoblots of polyacrylamide gel-electrophoresed proteins before and after surface proteolysis showed that the predominant antigenic determinants were on surface-exposed polypeptides. These polypeptides have extensive hydrophobic characteristics, as demonstrated by Triton X-114 phase partitioning. The electrophoresed proteins from cells grown in medium containing [14C]palmitate were blotted onto nitrocellulose which was both reacted with the MAbs and exposed to X-ray film. Superimposable bands on both the immunoblots and the exposed film suggested that the proteins might be acylated. The MAbs were further tested for reactivity with 16 other strains of M. hominis isolated from patients with septic arthritis (1 strain), septicemia (10 strains), or nongonococcal urethritis (1 strain); from the cervix (1 strain), rectum (1 strain), or surgical wound (1 strain) of patients; and from a contaminated cell culture. No single protein was consistently recognized from strain to strain, although a 94-kDa protein from 16 of the 17 strains tested was bound by at least one of the MAbs. The apparent antigenic heterogeneity among strains of M. hominis, including those isolated from the same tissue source and/or from patients with the same type of clinical disease, might be misleading in that all strains express epitopes associated with a discrete number of proteins to which one, two, or all three MAbs bind. The expression of the epitopes on multiple proteins from the same or different strains may reflect a mechanism for generating antigenic diversity.

An 18-year-old man was admitted to Hamamatsu University Hospital on February 15, 1985, with high fever, vesicular and papular rash involving the skin and mouth, conjunctivitis, productive cough and dyspnea. A diagnosis of Stevens-Johnson syndrome was made by skin biopsy, and chest X-ray showed an infiltrate in the right lower lung filed. Despite treatment with corticosteroids and antibiotics, the mucocutaneous lesions did not heal, and the pneumonia progressed to both lung fields. Because the patient had developed dyspnea, a tracheotomy was performed, mechanical ventilatory support was instituted, and high-dose corticosteroid therapy was started. However, jaundice due to intrahepatic cholestasis, hematuria, hematochezia, sepsis, and subcutaneous and mediastinal emphysema ensued, and the patient died of respiratory failure on March 1. Postmortem examination of the lung demonstrated diffuse alveolar damage. The complement-fixation titer for Mycoplasma was 1:64, compared with a level of less than 1:4 on admission. This case was though to be one of fulminant Mycoplasma pneumoniae infection presenting with Stevens-Johnson syndrome, respiratory failure and other extra-pulmonary complications.
