Distribution and persistence of XXXX nasal carriage among a population in which @entity1201 is endemic in Indonesia.

@entity1 @entity281 @entity4430 @entity1201
In order to understand better the relationship among @entity4430 , its transmission and the @entity1 host or the @entity281 which may lead to the development of @entity1201 , we performed a population survey in which nasal carriage of @entity4430 was determined by a specific polymerase chain reaction (PCR), 2 years after an earlier survey in the same population. 1923 @entity1 were registered, 1171 were clinically examined for signs of @entity1201 , and 418 were tested by PCR. The detection rate of @entity1201 in the study area had not changed significantly during the 2 years' observation period since the introduction of multi-drug therapy, i.e. 6/1000 compared to 7.7/1000 2 years before. Of 6 newly detected cases, 5 were diagnosed as having paucibacillary @entity1201 . The presence of @entity4430 could be demonstrated by PCR in 2.9% (12/418) of the @entity1 . PCR positivity was not persistent over the 2 years. All the PCR positive @entity1 identified in the first survey were negative in the second, indicating that @entity4430 nasal carriage is transient. As in the previous survey, we found evidence for widespread @entity4430 nasal carriage as determined by PCR among the general population in an area in which @entity1201 is endemic. In addition, our data indicated that PCR positivity can occur in certain clusters in the community. This clustering seems to be time-dependent, not necessarily related to the presence of @entity1 .
