Antibiotic susceptibility patterns of Neisseria meningitidis isolates from patients and asymptomatic carriers.

چکیده
The activities of seven antimicrobial agents used for treatment and prophylaxis of meningococcal disease was investigated against 901 Neisseria meningitidis isolates, 112 of which were recovered from patients and 789 of which were recovered from asymptomatic carriers. The proportions of isolates with decreased susceptibility to penicillin were 55.3 and 39.0%, respectively. Penicillin- and ampicillin-intermediate strains were more common among serogroup C meningococci than among non-serogroup C meningococci from both patients and carriers.

Antibiotic susceptibility of invasive Neisseria meningitidis isolates from 1995 to 2008 in Sweden—the meningococcal population remains susceptible SARA THULIN HEDBERG, PER OLCÉN, HANS FREDLUND & MAGNUS UNEMO
The susceptibility to 7 antibiotics was determined for all Swedish invasive Neisseria meningitidis isolates from 1995 to 2008 (N = 717). In general, these remain highly susceptible to the antibiotics recommended for use. Accordingly, penicillin G remains effective for the treatment of invasive meningococcal disease and ciprofloxacin appropriate for prophylaxis. Introduction The continuing incre...
متن کاملGenetic basis for nongroupable Neisseria meningitidis.
Nongroupable Neisseria meningitidis may constitute one-third or more of meningococcal isolates recovered from the nasopharynx of human carriers. The genetic basis for nongroupability was determined in isolates obtained from a population-based study in which 60 (30.9%) of 194 meningococcal isolates from asymptomatic carriers were not groupable. Forty-two percent of nongroupable isolates were rel...
متن کاملSerogroups and antibiotic susceptibility patterns of Neisseria meningitidis isolated from army recruits in a training camp.
Invasive Neisseria meningitidis infection is rare but carries a high mortality rate. The carriage rate in the normal population is around 10% and can be higher in confined populations. A study on the prevalence of carriage of N. meningitidis was conducted among 3195 army recruits after 2 months of intensive training in an army camp. N. meningitidis was isolated from 37.0% of these recruits. Two...
متن کاملShifts in the Antibiotic Susceptibility, Serogroups, and Clonal Complexes of Neisseria meningitidis in Shanghai, China: A Time Trend Analysis of the Pre-Quinolone and Quinolone Eras
BACKGROUND Fluoroquinolones have been used broadly since the end of the 1980s and have been recommended for Neisseria meningitidis prophylaxis since 2005 in China. The aim of this study was to determine whether and how N. meningitidis antimicrobial susceptibility, serogroup prevalence, and clonal complex (CC) prevalence shifted in association with the introduction and expanding use of quinolone...
متن کاملNeisseria meningitidis: an overview of the carriage state.
During periods of endemic disease, about 10 % of the general population harbour Neisseria meningitidis in the nasopharynx. Since N. meningitidis is a strict human pathogen and most patients have not been in contact with other cases, asymptomatic carriers are presumably the major source of the pathogenic strains. Most carrier isolates are shown to lack capsule production. The capsule deficient s...
