RESUMEN
This paper reports a case of acute purulent rhinitis caused by Streptococcus pneumoniae in a HIV/AIDS patient seen at the Hospitalization Center of "Pedro Kourí" Tropical Medicine Institute. The clinical findings were fever, severe purulent rhinorrea and affected general condition. Streptococcus pneumoniae was isolated with standard and advanced diagnosis techniques. Antimicrobial sensitivity test revealed that it was sensitive to cefaloridien, ampicillin, penicillin G and oxacillin. The patient was treated with a dose of 2 g of ampicillin daily for 10 days. The clinical picture of the patient improved and there was a total remission of the symptoms.

64 Haemophilus influenzae strains circulating in Havana City during a year were characterized by the carbohydrate fermentation method for the first time in Cuba. The fermentative pattern D was the most frequently found. Patterns D and G together were 72% of the total of strains studied. The combination of the carbohydrate fermentation with serotyping and biotyping allowed a greater differentiation of strains (14 groups). Patterns A, B, C and F appeared in children over 6 months of age, and pattern G in the group from 6 to 18. Patterns D and G predominated in the bacterial meningoencephalitis. A higher heterogeneity was observed among the strains isolated from acute respiratory infections. Some of the advantages of the Haemophilus influenzae strains subtyping method are stressed, such as: simplicity, easiness to be applied and interpreted, and the fact that it is not necessary a qualified personnel or a specialized laboratory for its implementation.

A prospective study was carried out in order to assess nosocomial bacteremia in the Intensive Care Unit of the Centrohabana Teaching Pediatric Hospital, from January to May 1988. 66.7% of the bacteremia episodes diagnosed were of a nosocomial origin, mostly secondary. Nosocomial bacteremia rate was 15.5 per 100 admissions, with predominance in the age group under 1 year of age. Risk factors for acquiring nosocomial bacteremia were hospital stay longer than 72 hours, age under 1 year, tracheal intubation, deep venous catheterization and urinary catheterization. The most frequently associated microorganisms were Staphylococcus epidermis, Escherichia coli and Pseudomonas aeruginosa.

A study was made on 198 Pseudomonas aeruginosa strains isolated at a pediatric intensive care unit from January to August 1988, using pyocin typing and antibiotic typing as markers. The most frequent circulating pyocin types were 31.83 and atypical 23578. The germ showed high resistance in vitro to the antimicrobial drugs used and the resistance patterns were distributed in 19 different antibiotic types.

The microbiologic aspects of the bacteriemia were prospectively studied in patients hospitalized in a pediatric Intensive Care Unit. Thirty six episodes of bacteriemia were detected in 29 patients. Secondary bacteriemia prevailed on the primary ones. The most frequent infectious foci associated with bacteriemia were the infections of respiratory tract, followed by intravascular catheterism. The microorganisms more frequently associated with bacteriemia were: Haemophilus influenzae, Staphylococcus epidermidis, Eacherichia coli and Pseudomonas seruginosa.

A study is made of non-fermenting gram-negative bacterial strains isolated at the Microbiology Lab, "Centro Habana" Pediatric Teaching Hospital. The strains studied come from various types of samples with prevalence of exudates and smears. A definite biotyping of 100% of strains is made. 90.0% are classified within the genus Pseudomonas. In addition, organisms of the genera Acinetobacter, Alcaligenes, Achromobacter, and Moraxella are identified. The most frequent species turned out to be Pseudomonas aeruginosa, which accounted for 68.4% of the total.

The use of King A and King B media for the faster diagnosis of Pseudomonas aeruginosa is introduced in the Microbiology Laboratory of Centro Habana Pediatric Teaching Hospital. The appropriate use of these media allows to classify as Pseudomonas aeruginosa 77.2% of the Pseudomonas sp. strains studied, which represent 95.2% of the total of strains identified as Pseudomonas aeruginosa, according to Hugh and Gilardi conventional technique. There are no significant differences in the implementation of the two procedures (X2: 0.5; p less than 0.05). The demonstrations of pyocines with King A medium is significantly superior to the method for extraction and solubility of the pigment in chloroform (X2: 15.05; p less than 0.01).
