Abstract
In vivo skin testing and in vitro lymphocyte blastogenesis were evaluated in a young adult population as methods for detecting cellular immunity to Sporotrichum schenckii. Similar procedures for Candida albicans and Coccidioides immitis were also investigated. 5 of 143 subjects had positive skin tests and 14 had positive blastogenic responses to S. schenckii. These 14 subjects also exhibited unusually high responses to C. albicans in vitro and 11 of the 14 were female. Data demonstrated a correlation coefficient of 0.89 when comparing the blastogenic assays for S. schenckii and C. albicans, suggesting cross antigenicity. Intact cellular immune mechanisms in combination with exposure to C. albicans may protect the host from systemic infection with S. schenckii. Although a limited number of subjects were studied, as a group, females had more vigorous cellular immune responses to C. albicans than males. The rare occurence of sporothrix infection in females as compared to males may be the result of antigenic stimulation from commonly observed vaginal colonization with C. albicans. The present data indirectly support this hypothesis.

Usage information is collected from two different sources: this site (JCI) and Pubmed Central (PMC). JCI information (compiled daily) shows human readership based on methods we employ to screen out robotic usage. PMC information (aggregated monthly) is also similarly screened of robotic usage.
Various methods are used to distinguish robotic usage. For example, Google automatically scans articles to add to its search index and identifies itself as robotic; other services might not clearly identify themselves as robotic, or they are new or unknown as robotic. Because this activity can be misinterpreted as human readership, data may be re-processed periodically to reflect an improved understanding of robotic activity. Because of these factors, readers should consider usage information illustrative but subject to change.
