Are Corynebacteria new emerging pathogens?

The book describes the epidemiological methods, useful in finding new pathogens, Non Diphteriae Corynebacteria, in the hospital "Sant'Orsola" (Bologna, Italy). The book suggests the understanding of their trends and the real impact in ordinary hospital activity. Some computations will be of support of the author research, some final deductions found irrelevant the microorganisms' role in clinical practice. Anyway interesting results from a microbiological point of view are drawn and will suggest the opportunity to study this emergence furtherly, especially in immunocompromised patients, due to the raise of inpatient costs which they cause. A technical narration and mathematical assumptions are distinctive traits of the book.
