"Chlamydia" is the perfect pathogen, remaining elusive to the host by hiding within its cells and to the researcher by being refractory to laboratory analysis. However the recent revolution in genomics and molecular biology have made a great impact on chlamydia research. Every chapter in this book draws on recently acquired genomic information. Written by the rising stars of chlamydial research, this comprehensive book covers literally every aspect of "Chlamydia" molecular and cellular biology. The book is divided into four sections: comparative and functional genomics; molecular and cellular pathogenesis; host responses and disease; emerging strategies for control. Topics covered include comparative genomics, genomics of environmental "Chlamydia", regulation of gene expression, tryptophan metabolism, chlamydiaphage, and much more. Essential reading for all, chlamydia researchers and recommended reading for other scientists working in bacterial molecular and cellular pathogenesis, bacterial genomics and antibacterial research.
