Furthermore, we reviewed french listeriosis investigation reports of the Institut de Veille Sanitaire and identified data on incubation period in three reports of unpublished outbreaks and one report of a sporadic foodborne case.
However, no information was available about any epidemiologic link between cystic fibrosis strain 47J26 to reported or unpublished outbreaks, and no clinical information was available about the patient from whom strain M18 was isolated.
This apparent publication bias, however, suggests that there may have been many unpublished small outbreaks and that this analysis may overestimate the transmission potential of smallpox because it is based only on published reports.
The Q1 spoligotyping data has revealed that this cluster is in fact intimately related with the B cluster identified in the 90s outbreak (unpublished data).
Surveillance data, published and unpublished case reports, and outbreak reports were reviewed.
However, preliminary data using sera from children who seroconverted to Rotarix® indicate that it is able to neutralize the G1P[8] outbreak strain (unpublished observations).
Genotype D4 and D8 have been isolated from different districts of Tamil Nadu over the last four years from sporadic cases as well as during outbreaks (National Institute of Virology, unpublished data).
The Farm B chili pepper harvest period (April 14 June 14) closely mirrors the range of illness onset dates in the multistate outbreak (April 16 August 26) (CDC and FDA, unpublished data).

Previously, pulsed-field gel electrophoresis (PFGE) revealed close genetic relatedness between a S. Typhi strain that was isolated from an asymptomatic carrier in 2007 and a strain that originated from a patient during the 2005 outbreak in Kelantan (unpublished data).
