Micrococcal urinary-tract infections in young women.

In a prospective study in young women, novobiocin-resistant subgroup-3 micrococci were the second commonest cause, after Escherichia coli; of acute urinary infections. Proteus mirabilis was the only other causative organism. Symptoms, pyuria, or possible aetiological factors were the same in micrococcal and coliform infections. The infecting micrococcus "biotype" was only rarely found among the normal flora of the genitourinary tract of young women, though other micrococci and staphylococci were commonly present. Evidently, the infecting micrococci are selectively pathogenic in the urinary tract. Micrococcal infections, like coliform infections; commonly followed sexual intercourse, but there was no evidence that the micrococci were sexually transmitted. The infecting biotype was rarely found in the male urethra or prepuce.

Proteus species isolated from human eyes.

Of 34 species of Proteus isolated from human eyes, 29 (85%) were P. mirabilis and five (15%) were P. morganii. In vitro antibiotic sensitivity studies showed that gentamicin best controlled both P. mirabilis and P. morganii of all the antibiotics tested. In vivo tests on experimental Proteus infections of rabbit coreas, treated with gentamicin and tobramycin, yielded comparable clinical results, but gentamicin was more effective in eliminating the organism from the experimental lesions.

Experimental lung injury. I. Bacterial pneumonia: ultrastructural, autoradiographic and histochemical observations.

Proteus infection in the rat produces an acute bacterial pneumonia which resolves without necrosis or significant organization within 2 weeks. Ultrastructural changes included widespread damage to type 2 cells and endothelial cells and rapid proliferation of the alveolar epithelial cells, which were the predominant site of labeling with tritiated thymidine. Histochemical staining for lysosomal enzymes showed an initial reduction in type 2 cell reactivity. The majority of proliferating epithelial cells were also unreactive until the normal pattern of staining and morphology returned at 8 to 12 days after infection. The acute inflammatory exudate was reactive, but there was only minimal to moderate staining in the subsequent clusters of alveolar macrophages. These data suggest that resolution with the preservation of the normal architecture of the peripheral airspaces may be correlated with superficial injury and limited reactivity for digestive enzymes.

[The effect of catecholaminergic agents on the efficacy of immunostimulants].

The influence of combinations of immunostimulants (prodigiosin, methyluracil, levamisole) and catecholaminergic agents (dopamine, haloperidol, noradrenaline, phentolamine, isoproterenol, propranolol) on the results of antibiotic therapy of acute generalized Proteus infection and primary immune response to ram erythrocytes was studied on outbred albino mice. It was established that the agents influencing dopaminergic, alpha- and beta-adrenergic receptors can in some cases change the efficiency of the studied immunostimulants. The direction and degree of their action depend on the administration schedule.

[Immunogenicity of a vaccine made from soluble Proteus antigens].

Hemagglutinins with different specificity were determined in 270 subjects: of these, 101 were examined in the time course before and after immunization with Proteus vaccine prepared from soluble antigens. The preparation possessed pronounced immunological potency and stimulated the formation of antibodies to the vaccine strain, to heterologous Proteus strains and to the common antigens of Gram-negative bacteria. The combined scheme of the subcutaneous and local administration of the above-mentioned Proteus vaccine ensured an increase in the synthesis of IgM and IgA in patients with Proteus wound infection. Active immunization ensured an essential rise in the level of hemagglutinins to Re-glycolipid in donors and oncological patients not infected with Proteus, but did not ensure the statistically significant shifts in the antibody level to Re-glycolipids in patients with chronic Proteus infection.
