ABSTRACT
The National Laboratory of Reference of Pathogenic Neisserias of "Pedro KourÝ" Tropical Medicine Institute studied 58 strains which had been previously identified as Neisseria meningiditis and isolated from nasopharyngeal carriers from 1985-1998. They were applied the knapp detection scheme plus the glutamiltransferase production test. The latter and the polyscharide production based on 5 sacarose allowed to make a differential diagnosis between N. meningitidis and Neisseria polyccharea. It was possible to identify a N. polysaccharia strain, a species that is reported for the first time in Cuba.

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.
