Neisseria meningitidis strains with decreased susceptibility to penicillin.

Neisseria meningitidis strains relatively resistant to penicillin were recovered from blood or cerebrospinal fluid cultures of four children treated in Barcelona, Spain, and surrounding areas. The four strains had distinct serogrouping and serotyping patterns. The minimal inhibitory concentrations of penicillin were 0.25 microgram/ml for three strains and 0.5 microgram/ml for the fourth strain. These are the first relatively penicillin-resistant meningococcal strains identified in Spain.

Antibiotic resistance and serotypes of 100 Streptococcus pneumoniae strains isolated in a children's hospital in Barcelona, Spain.

A total of 100 Streptococcus pneumoniae strains with various penicillin G susceptibilities, isolated in Barcelona, Spain, from different pediatric sources during 1983 and the first 4 months of 1984, were tested for susceptibility to tetracycline, chloramphenicol, erythromycin, clindamycin, vancomycin, and rifampin. The isolates were distributed in nine patterns of antibiotic resistance, and 15 different serotypes were encountered. The high incidence of resistance to multiple antibiotics clearly indicates the need to perform antibiotic susceptibility testing of all pneumococcal isolates with proved pathologic significance to avoid therapeutic failure.

[Mediterranean boutonneuse fever in children. Study of 139 cases].

A prospective study of 139 children suffering mediterranean spotted fever, all of them hospitalized during the summer time of the last five years is presented. Clinical features were high fever, maculopapulous rash and black eschar ("tàche noire"). Among analytical findings, leucocyte count was decreased in a 38.8% of children during the first week of illness. Weil-Felix test was positive in 47.2% for OX-2 and 52.7% for OX-19 of cases. The indirect immunofluorescence for rickettsial conorii was positive in 100% of cases in the second determination. 74.1% of patients received antimicrobial therapy and 25.9% symptomatic treatment. All children cured without complications.

Prevalence of Neisseria meningitidis in family members of patients with meningococcal infection.

The aim of the study was first, to determine the prevalence of Neisseria meningitidis among the family members living with patients suffering from meningococcal infections, and second, to ascertain the distribution among these family members of strains epidemiologically related to those isolated from patients. Forty-two family groups were studied and 135 nasopharyngeal samples were taken from family members living with patients. Twenty family groups were found to contain meningococcal carriers, and of these 20, 13 contained a carrier of the strain that caused the infection (65%). Among the family members who were carriers, the mother and father most frequently yielded the strain which caused the illness. The serotypes most frequently encountered both in patients and carriers were 2 and 8, as well as nontypable strains. The polyacrylamide gel electrophoretic patterns (PAGE) most frequently found were II and IV. A notable feature of the study is the high resistance of the strains to sulphadiazine, since more than 90% of the strains found in patients and more than 75% of those from carriers possessed a minimum inhibitory concentration greater than or equal to 10 micrograms/ml.

[Antibiotic sensitivity of Streptococcus pyogenes in pediatrics].

BACKGROUND: The purpose of this study was to set up the current level of Streptococcus pyogenes sensitivity, in pediatric patients in our community, to penicillin, clindamycin, clarithromycin, erythromycin and azithromycin. MATERIAL AND METHODS: 100 strains were collected between October 1996 to July 1997. 79 were pharyngeal and 21 were non-pharyngeal strains. The MICs were obtained by the E-test method, and furthermore the results were compared by the Kirby-Bauer method. RESULTS: All strains were sensitive to penicillin and except one (inducible resistance) to clindamycin. 19% were resistant to macrolide, without differences among clarithromycin, erythromycin and azithromycin. From 13 strains (16.5%) of pharyngeal and 6 (28.5%) from non-pharyngeal samples, 4 of these from cutaneous samples, showed resistance. 18 of the resistance strains belonged to novel resistance fenotip and one to 10 inducible fenotip. Only minor discrepancies about erythromycin and clindamycin were observed between E-test and Kirby-Bauer methods. CONCLUSIONS: This study confirms a remarkable level of resistance to macrolides in pediatric patients, mainly in the cutaneous samples. Due to the reduced prevalence of macrolide-susceptible strains, in vitro susceptibility testing appears necessary in case of macrolide chemotherapy.

[Neonatal infection by Streptococcus agalactiae. Multicenter study in the area of Barcelona, Spain].

BACKGROUND: Streptococcus agalactiae or streptococcus group B (SGB) is the main etiologic agent of early neonatal sepsis. A multicenter study was performed with the aim of determining the incidence and characteristics of this disease in our medium and contribute the design of an adequate prevention protocol. METHODS: Ten hospitals and two primary health care centers were implicated in the study; 103 microbiology confirmed episodes of SGB neonatal sepsis (blood and/or LCR positive) were reported from 1994 to 1996. RESULTS: The incidence of early SGB neonatal sepsis was 1.48/1,000 live births with a mortality of 8.7%. The cultures, for detecting the state of the SGB carrier were performed in only 26 (25%) of the patients. At least one of the factors described for risk of perinatal SGB infection was observed in 46% of the mothers, with the most frequent being prolonged amniorrhea (26%), intrapartum fever (17%), and early delivery (14%). At the time of delivery only 10.7% of the mothers received endovenous antibiotherapy. CONCLUSIONS: From these results the following recommendations have been made: a) detection of SGB carriers by the systematic practice of blood cultures in the last weeks of gestation and b) the administration of intrapartum antibiotic prophylaxis in both early births (< 37 weeks) and in all the SGB carriers should be undertaken. With these measures we aim to decrease the neonatal infections by streptococcus group B.
