The gene encoding lysostaphin of Staphylococcus staphylolyticus was cloned in Escherichia coli and its DNA sequence was determined. The complete coding region comprises 1440 base pairs corresponding to a precursor of 480 amino acids (molecular weight 51 669). It was shown by NH2-terminal amino acid sequence analysis of the purified extracellular lysostaphin from S. staphylolyticus that the mature lysostaphin consists of 246 amino acid residues (molecular weight 26926). Polyacrylamide gel electrophoresis revealed a similar molecular weight for the most active form. By computer analysis the secondary protein structure was predicted. It revealed three distinct regions in the precursor protein: a typical signal peptide (ca. 38 aa), a hydrophilic and highly ordered protein domain with 14 repetitive sequences (296 aa) and the hydrophobic mature lysostaphin. The lysostaphin precursor protein appears to be organized as a preprolysostaphin.

This article explores the relationship between medicine’s history and its digital present through the lens of the physician-patient relationship. Today the rhetoric surrounding the introduction of new technologies into medicine tends to emphasize that technologies are disturbing relationships, and that the doctor-patient bond reflects a more ‘human’ era of medicine that should be preserved. Using historical studies of pre-modern and modern Western European medicine, this article shows that patient-physician relationships have always been shaped by material cultures. We discuss three activities – recording, examining, and treating – in the light of their historical antecedents, and suggest that the notion of ‘human medicine’ is ever-changing: it consists of social attributions of skills to physicians that played out very differently over the course of history.

This contribution explores how Forrester’s work on cases has opened up an arena that might be called ‘the medical case as a travelling genre’. Although usually focused on the course of disease in an individual patient and authored mostly by one medical author, medical case histories have a social dimension: Once published, they often circulate in networks of scholars. Moreover, scholars of the history of literature have shown that numerous medical cases seem to travel easily beyond the context of medical science into the realm of popular literature and journalism. After tracing the idea of cases travelling in Forrester’s Thinking in Cases, I discuss several contributions by authors who, in the wake of interdisciplinary research on cases in the past two decades, have dealt in different ways with this idea. In the third section, I present my own research on a case of self-crucifixion that was widely discussed in 19th-century Europe. I suggest that understanding the case as a ‘traveling genre’ – an expression borrowed from literary genre theory – highlights the role of readers and publication formats as constitutive for cases, and enables us to see more clearly what cases do for scientists and writers who work with them.
