Spanish microbiology in an era of constant advances: a view from the battleground

It has been 75 years since a group of pioneers founded the Spanish Society of Microbiology (SEM). Among them were, in addition to university professors and research scientists, microbiology practitioners from clinical laboratories, public health, and industry. This account describes the trajectory of the SEM, as a focal point of cooperation for the development of Microbiology in Spain during the more than seven decades of its existence. The efforts of its members resulted in everything from promoting a scientific environment to leadership of some of the activities of the Federation of European Microbiological Societies (FEMS). My interest was to frame the development of Microbiology in Spain in the context of the continuous advances of microbial studies in the world. Indeed, since the 1940s, description of and experimentation with microbial species has provided a deep understanding. Furthermore, it has furnished model systems used to establish basic concepts in Life Sciences, as well as the most appropriate technological instruments for the advancement of Omics, Systems Biology, and Synthetic Biology. Those who 75 years ago dreamed of the progress of our discipline in Spain perhaps did not imagine that the Spanish microbiologist Francisco Mojica would contribute to essential knowledge, making the acronym "CRISPR" the most used across the world of Life Sciences and Biomedicine.
