Mycobacterium research and diagnosis

Mycobacterium research and diagnosis is a research topic within Epidemiology. Science Explorer counts 50k research works in it since 1950. 10.1% of them reached the world's top 10% most cited for their field and year.

This cluster of papers focuses on the diagnosis, treatment, and epidemiology of nontuberculous mycobacterial diseases, with a particular emphasis on Mycobacterium avium and Mycobacterium abscessus. It covers topics such as the impact of genotypic studies, antibiotic resistance, prevalence in specific patient populations (e.g., Crohn's disease, cystic fibrosis), and environmental sources. The cluster also delves into genomic and comparative genomic studies supporting the division of the genus Mycobacterium.

How concentrated that is

The same countries as shares of everything the list above accounts for. A node where two countries do two thirds of the work and one spread evenly across twelve read alike as a ranking and not at all alike here.
