Microorganisms are ubiquitous and may be found in almost every environment on earth. As such, they are a diverse group with an assortment of genotypic and phenotypic features and varying growth and reproduction requirements. There is continual interaction between humans and microbes, ranging from disease-causing pathogenic organisms invading the human body to microorganisms harnessed by humans to aid in the fermentation of food products. The detection and characterization of these organisms enables us to better understand how to manipulate and exert some control over their impact on our lives and welfare. This TriMark Publications report describes the specific segment of the in vitro diagnostics (IVD) market known as the diagnostic microbiology and focuses primarily on the automated microbial testing systems. Within medical diagnostics, automated microbial testing for infectious disease-causing organisms offers one of the brightest areas for growth and innovation. The confluence of breakthroughs in genomics and proteomics--as well as the development of microarray devices--have led the microbiology market to accept the power of advanced analytical techniques for the diagnosis and treatment of infectious disease. For this analysis, the automated microbial testing market has been divided into the following segments for this examination: 1) microbial detection, 2) microbial enumeration, 3) microbial identification and 4) detection of antibiotic resistance. This report analyzes the size and growth of the automated microbial testing market in its applications for infectious disease detection and therapy, examining the factors that influence the various market segments and the dollar volume of sales, both in the U.S. and worldwide.
