Absence of Neisseria meningitidis W-135 Electrophoretic Type 37 during the Hajj, 2002
نویسندگان
چکیده
We document the absence of carriage of Neisseria meningitidis W-135 of the sequence type 11 in returning pilgrims after the Hajj 2002. This finding contrasts with the 15% carriage rate we previously reported in pilgrims returning from the Hajj 2001. The epidemiology of carriage may be changing or may have been controlled by vaccination and a policy of administering antibiotics to pilgrims from countries with a high incidence of meningococcal disease.

Emergence of Neisseria meningitidis W-135 in the context of other rare serogroups
Neisseria meningitidis can be considered a continually emerging pathogen due to its genetic mutability and dynamic epidemiology. Currently, six serogroups (A, B, C, W-135, X and Y) are important to global disease epidemiology. Until 2000, serogroup W-135 was rare worldwide. Hajj-associated W-135 outbreaks caused by a virulent ST-11 strain in 2000 and 2001 raised concerns about widespread epidem...

We present the first reported case of systemic infection with Neisseria meningitidis serogroup W-135 sequence type (ST)-11 in Japan. A 44-year-old woman presented with high fever, sore throat, and fatigue and was diagnosed with N. meningitidis bacteremia. The causative strain was identified as serogroup W-135 ST-11 by polymerase chain reaction and multilocus sequence typing. Approximately 1 mon...
متن کاملHajj-Related Neisseria Meningitidis Serogroup W135 in Mauritius
Meningococcal disease is rare in Mauritius; only one case was reported from 1992 to 1999. However, since June 2000, four cases have occurred. Epidemiologic information and typing results indicate that these recent cases probably followed the introduction of Neisseria meningitidis W135 in Mauritius by pilgrims returning from the Hajj in 2000 and 2001.
متن کاملFirst report of capsule replacement among electrophoretic type 37 Neisseria meningitidis strains in Italy.
This report describes the C-to-B capsular switching in four Neisseria meningitidis strains belonging to the electrophoretic type 37 (ET-37) complex. In particular, one strain belonged to the new sequence type 1860, which was first detected in the year 2000 in Italy and is now frequently isolated. The presence of switched serogroup B strains deserves special attention if they prove as able to sp...
