MICROBIOLOGY. For the article “Pneumococcal carriage results in ganglioside-mediated olfactory tissue infection,” by Frederik W. van Ginkel, Jerry R. McGhee, James M. Watt, Antonio Campos-Torres, Lindsay A. Parish, and David E. Briles, which appeared in issue 24, November 25, 2003, of Proc. Natl. Acad. Sci. USA (100, 14363-14367; first published November 10, 2003; 10.1073/pnas.2235844100), the authors note that the day 4 colonization data of strain EF3030 of the nasal washes have been omitted from Fig. 1B. The corrected figure and its legend appear below.
Fig. 1.
Nasal delivery of 3 ×106 cfu of either the nonencapsulated R36A strain or the virulent EF3030 strain of S. pneumoniae to xid mice. The neuronal tissues (ON/E, OB, and brain) and the lymphoid tissues (NALT, CLN, and lungs) were collected, minced, and analyzed for the presence of live pneumococci at 1 and 4 days after nasal challenge. Indicated is the mean of log10 cfu ± 1 SE. The 0 value on the y-axis represents the absence of detectable cfu. Indicated are the mean cfu ± SE of five mice per group; data are representative of three different experiments.
