[Antimicrobial sensitivity of 402 strains of Neisseria gonorrhoeae isolated in 7 Spanish cities].

To study N. gonorrhoeae resistance in Spain. We evaluate 402 strains consecutively isolated in 7 Spanish cities (Barcelona, Bilbao, Madrid, Murcia, Seville, Valencia and Valladolid). The MIC to 9 antimicrobial agents was determined by agar-dilution (DST) method. We found a high incidence (15.7%) of penicillinase producer strains (NGPP). Most (53.3%) of all non-NGPP strains showed reduced sensitivity to penicillin and 1.5% of the strains had chromosomally mediated resistance. All NGPP strains and 90% of non-NGPP strains showed reduced sensitivity to tetracycline (MIC greater than 0.23 mg/l). We did not found any strain with high-level tetracycline resistance. MIC90 for the other drugs tested were: erythromycin, 0.125 mg/l; spectinomycin, 16 mg/l; cefoxitin, 2 mg/l; cefuroxime 0.06 mg/l; ceftriaxone 0.0037 mg/l; ofloxacin 0.06 mg/l and ciprofloxacin, 0.0018 mg/l. NGPP are very prevalent in Spain. Most of these strains had chromosomally mediated resistance to penicillin and tetracycline. We did not found resistance to other antimicrobial agents.

Immunology of dermatophytosis. Experimental study.

By causing experimental lesions of dermatophytosis in rabbits inoculated and reinoculated with T. mentagrophytes var. granulosum and T. rubrum a study was carried out of the state of cellular immunity response, during infection, and also of the antigens responsible for the sensitization. Cellular immunity response was detected using the leucocyte migration test (L.M.T.) in the presence of antigenic compounds of the 'Keratinase' of Eleuterio et al.

[Experimental dermatomycosis, a clinico-pathological study].

Using rabbits, we have studied the effect of reinfection of T. mentagrophytes var granulosum and T. rubrum into lesions that were previously infected and resolved. Clinical mycological and histopathological studies were done for 16 weeks. Timentagrophytes produced a more severe infection than T. rubrum. The clinical lesions produced by reinoculation were less intense and long lasting.
