RESUMO
Seven countries in Latin America and the Caribbean report on (2010 and 2011) the susceptibility of 2235 isolates of Neisseria gonorrhoeae to 6 antibiotics. Thirteen isolates had ceftriaxone minimum inhibitory concentrations (MICs) of 0.125 to ≥ 0.25 mg/L. The percentage of resistant isolates to the following antibiotics was: azithromycin, 1.0% to 1.7%; ciprofloxacin, 42.1% to 36.2%; penicillin, 31% to 35%; tetracycline, 21.8% to 22.6%.

Ninety strains of Pseudomonas aeruginosa isolated from pediatric patients with cystic fibrosis and respiratory infections at "William Soler" pediatric hospital were studied in the period from February to August, 2001, as part of a joint research project of the two hospitals. In vitro susceptibility of these strains to 10 antimicrobials, that is, azlocylline, ceftazidime, cefotaxime, ceftriaxone, gentamicin, tetracycline, ciprofloxacine, ofloxacine, chloranphenicol and trimethroprim/sulfamet-hoxazole was studied by Kirby-Bauer disk diffusion. The reference strain was ATCC 27853. The research work results showed that antimicrobial susceptibility values were within the allowable limits. Increased resistance to chloranphenicol (87.03%) and trimethoprim/sulfametoxazole (92.28%) as well as high sensitivity to azlocylline (85%), ceftazidime (87.09%), gentamicyn (94.09%), ciprofloxacine (94.8%) and ofloxacine (92.5%) were observed.

The Gonoccocus Laboratory of "Pedro KourÝ" Tropical Medicine Institute carried out a study of in vitro susceptibility of Neisseria gonorrhoeae to penicillin, tetracycline, cefuroxime ceftriaxone, cefotaxine and ciprofoxacin by means of a disk diffusion method with the culture medium agar base GC plus supplement. In the first phase, the method was standardized and the reference N. gonorrhoeae ATCC 49226 strain was used whereas in the second phase, 50 gonococcal strains isolated in 8 provinces during 1995 and 1996 were examined. The results of such standardization confirmed that the antimicrobial susceptibility values were within the allowable limits. 52 and 34 of strains were resistant to penicillin and tetracycline respectively and all of them showed susceptibility to the rest of evaluated antimicrobial drugs. We recommend the use of the disk diffusion method for surveillance of gonococci resistance to these drugs in our country.

Se realizo un estudio prospectivo en 40 trabajadores de una granja avicola (grupo 1) considerados con riesgo de exposicion a Histoplasma capsulatum, agente etiologico de la histoplasmosis, y en 16 individuos sin riesgo profesional de exposicion a dicho agente (grupo 2). En ambos grupos se aplico la prueba intradermica de histoplasmina y se obtuvo el suero antes de su aplicacion y a los 30 y 180 dias despues de realizada dicha prueba...
