RESUMO
BACKGROUND: Methicillin-resistant Staphylococcus aureus is an increasing problem in the Caribbean. We investigated the molecular epidemiology of MRSA isolates on Cuba. FINDINGS: The predominant clone was of the spa type t149, followed by community-associated MRSA USA300. CONCLUSIONS: We report the first molecular typing results of MRSA isolates from Cuba.
RESUMO
Antimicrobial susceptibility of 79 non-typable Haemophilus influenzae isolations obtained from healthy children that attended two day-care centers in Marianao municipality. It was found resistance to trimetoprim/sulfamethoxazole (41,77 %), tetracycline (18,99), ampicilline (17,72 %), amoxicillin/ clavulanic acid (7,59 %) and chloramphenicol (6,33 %). 25,81 % of isolates showed multiresistance. 100 % of studied cases was sensitive to ceftriaxone, cefuroxime and norfloxacin. 28,57 % of ampicilline-resistent isolates produced beta-lactamase enzyme. Chloramphenicol resistance was mediated by the production of chloramphenicol acetyltransferase enzyme.

Haemophilus influenzae B(Hib) is often associated with serious systemic infections in children under 5 years of age. Since 1993, it is the most frequent agent isolated in meningoencephalitis. All the strains isolated in the country have been characterized in the National Reference Laboratory at the "Pedro KourÝ" Tropical Medicine Institute. Results revealed that 97 of strains isolated from bacterial meningoencephalitis in Cuba during the period 1993-1995 corresponded to serotype B, 0.6 to serotype A and 2.4 not belong to any serotype. The classification of serotype B-strains into biotypes proved that 76 was biotype I and 21 biotype II, 8 to biotype III and 1.2 was biotype V. This study found the following resistance to ampicillin 40, to chloranphenicol 43.3, sulpha metoxazol 36, trimetroprim 37.3 and tetracycline 31.
