Rifampin-resistant Meningococcal Disease

چکیده
Rifampin-resistant meningococcal disease occurred in a child who had completed rifampin chemoprophylaxis for exposure to a sibling with meningococcemia. Susceptibility testing of 331 case isolates found only 1 other case of rifampin-resistant disease in Minnesota, USA, during 11 years of statewide surveillance. Point mutations in the RNA polymerase Beta subunit (rpoB) gene were found in isolates from each rifampin-resistant case-patient.

Rifampin-resistant Neisseria meningitidis
To The Editor: Immediate management of meningococcal disease requires antimicrobial drug treatment of patients with β-lactams and chemo-prophylaxis of contact persons with rifampin. High-level resistance to rifampin (MIC >32 mg/L) in Neisseria meningitidis is provoked by mutations (most frequently at the residue His 552) in the rpoB gene encoding the β subunit of RNA poly-merase (1,2). Resistan...
متن کاملA cluster of meningococcal disease caused by rifampicin-resistant C meningococci in France, April 2012.
In April 2012, a cluster of two cases of meningococcal disease caused by rifampicin-resistant C meningococci was reported in the Champagne-Ardenne region, France. The two cases occurred in a student population living in the same town but studying at different schools. Bacteriological and epidemiological investigations of cases have shown that the isolates of both cases were non-differentiable.

the upstream rpoBF1 but with a DNA uptake sequence (in lower case) that was added at the 5′ end to permit DNA transformation (7). The transformant strain NM05-08 was resistant to rifampin (MIC >32 mg/L), and the sequence of the rpoB gene confirmed the His→Tyr mutation. When compared to the parental isolate (LNP21362), strain NM05-08 showed reduced virulence. Indeed, bacterial loads were similar...

Meningoccocal disease has repeatedly caused outbreaks worldwide. There has been sudden surge of cases of meningococcemia and meningococcal meningitis in early 2005 in Delhi, India and neighboring states of Uttar Pradesh and Haryana. As of June 17, 2005, 429 probable cases of meningococcal disease have been reported in Delhi out of which 128 cases have revealed microbiological evidence of Neisse...

The National Neisseria Network (NNN) has undertaken meningococcal isolate surveillance by means of a collaborative laboratory based initiative since 1994. The phenotype (serogroup, serotype and serosubtype) and antibiotic susceptibility of 343 isolates of Neisseria meningitidis from invasive cases of meningococcal disease were determined in 1997. Ninety six percent of the invasive isolates were...
