Genetic Control of the Susceptibility to Bacterial Infection

This series ofreviews focuses on recent developments in understandingbacterialpathogenesisthathavebeengained by studying the genetic control of the susceptibility to particular diseases. The topics of the reviews include a description ofbacterial genes that effect virulence and a studyofthe genetic susceptibilityofhumans to group A streptococci and to leprosy. The most versatile model system for studies of disease susceptibility is the inbred mouse. Although seven of the chapters deal with the geneticsoftheresistanceofmice to infection, allofthem point out general principles and, wherever possible, parallelswithappropriatehumandiseases. Genetic studies of the mechanisms of resistance and pathogenesishaveanadvantageoverotherapproaches. By utilizing animals ofappropriate genotypes, it is possible tostudytheinvivoconsequencesofvariationsinparticular hostdefensesinintactanimals.Someofthemoderngenetic approachesusedinmousegeneticsarealsodescribed.

Thebulkofthevolumefocusesonthegeneticregulation by three different murine loci: Ips, xid, and fty. fty was the first name given to a locusthatgoverns resistance to infections with leishmania, bacille Calmette-Guerin and salmonella. Different reviews describe the relationshipof thefty locusto thediseasescaused bytwoofthese three pathogens. Thesetwo reviewsalsoincludeadiscussionof other geneticfactors that affect the susceptibilityofmice toeachpathogen.TworeviewsaredevotedtotheX-linked immunodeficiency (xid) locus.
