Here, we report the simultaneous isolation of Pseudomonas straminea from blood cultures and from a skin ulcer in an elderly woman who suffered from atopic dermatitis and psoriasis and developed acute cellulitis of both arms requiring hospital treatment. To the best of our knowledge, P. straminea has not been previously reported to cause invasive infections in humans. This case highlights how chronic diseases and older age increase the susceptibility to bacterial infections with environmental bacteria of low virulence. Our study describes the microbiological identification of the blood culture isolate, including morpho-molecular characterization and virulence demonstration in a Galleria mellonella model.

In the three consecutive years of 2022–2024, three female specimens of the phlebotomine sandfly Phlebotomus mascittii were trapped in two locations in the vicinity of Coblenz, western Germany. These records slightly expand the distribution limits of the species in the Federal State of Rhineland-Palatinate to the north, at latitudes 50°18'N and 50°15'N, respectively, and represent the second northernmost Palearctic sandfly locations so far.
