Erratum vol. 8, no. 1.In the article, "A Large Outbreak of Legionnaires' Disease Legionnaires' disease A type of pneumonia usually caused by infection with the bacterium Legionella pneumophila, but occasionally with a related species (such as L. micdadei or L. dumoffii). at a Flower Show, the Netherlands," by Jeroen W. Den Boer et al., errors appear in two figures and their legends. In Figure 3, part 3a should be identified as IgM and part 3b as IgG. The correct legends are as follows: Figure 3a. Smoothed mean geometric immunoglobulin immunoglobulin: see antibody; immunity; immunology. Immunoglobulin Any of the glycoproteins in the blood serum that are induced in response to invasion by foreign antigens and that protect the host by eradicating pathogens. (Ig) M antibody titers antibody titer The amount of a specific antibody present in the serum, usually as a result of an acquired infection; titers for IgM usually rise abruptly at the time of infection–acute phase and fall slowly; during the 'convalescent' phase, IgG ↑ and is to Legionella pneumophila Legionella pneumophila is a thin, pleomorphic, flagellated Gram-negative bacterium of the genus Legionella.[1] L. pneumophila is the primary human pathogen in this group and is the causative agent of legionellosis or Legionnaires' disease. of nearest 35 exhibitors in Halls 3 and 4 per 63 [cm.sup.2] of exhibition area; confirmed and probable cases among exhibitors in halls 3 and 4. * = confirmed case in exhibitor; o= probable case in exhibitor; Bu = bubblemat; W = whirlpool spa. Figure 3b. Smoothed mean geometric IgG antibody titers to L. pneumophila of 35 exhibitors nearest to whirlpool in halls 3 and 4 per 63 [cm.sup.2] of exhibition area; exhibitors ill with confirmed and probable cases in halls 3 and 4. * = confirmed case in exhibitor; o= probable case in exhibitor; Bu = bubblemat; W: whirlpool spa. In Figure 4, parts b and c were inadvertently omitted. The complete figure appears below. The correct legends are as follows: Figure 4. Exhibition hall, West Frisian The West Frisian can mean:
