Background
Mixta calida, previously known as Pantoea calida, is an environmental bacterium rarely associated with human pathologies. Rare case reports mention sepsis, meningitis and implantable defibrillator infection.
Case presentation
A 67-year-old female with multiple comorbidities was referred to the emergency room for a comminuted fracture of both right tibial plateaus secondary to a fall and for which she benefited from an external fixator. After removal of the fixator, failure of osteosynthesis and placement of a new fixator, a skin necrosis appeared and a propeller distal anteromedial thigh perforator flap was performed. After 6 weeks, she presented a necrosis of the flap and an osteitis. The bone biopsy was positive with pure M. calida. The patient underwent an above-knee amputation, but 6 weeks later the wound was dehiscent and again positive with pure M. calida.
Conclusions
Serious infections due to M. calida are uncommon but can occur in immunocompromised patients. This case illustrates the first reported osteitis and skin necrosis due to M. calida.

Background
Early in the COVID-19 pandemic, convalescent plasma (CP) emerged as a potentially effective treatment neutralising SARS-CoV-2. Early CP therapy with high neutralising antibody (NAb) titre may benefit COVID-19 outpatients and, in sufficient quantities even some hospitalised patients. This study details the process of setting up a CP bank, containing high- and low-titre CP for a clinical trial.
Study design and methods
We identified 18–65-year-old convalescents with SARS-CoV-2 NAb titres of ≥1:40 in microneutralisation test (MNT). Following eligibility pre-screening, the Finnish Red Cross Blood Service (FRCBS) determined suitability as CP donors.
Results
Of the 6466 COVID-19 convalescents contacted, 1481 provided serum, with 851 (57.5 %) exhibiting NAb titres ≥1:40. Participation barriers included reluctance, advanced age and, for women, insufficient body size. Of the volunteers, 125 were evaluated at FRCBS, with major exclusions for HLA antibodies (42 women), interferon antibodies (five men), and NAb titres waning below 1:20 (16 participants). Finally, 70 underwent plasmapheresis, resulting in 50 suitable CP donors (0.8 % of initial contacts and 3.4 % of those tested for NAb).
Discussion
The process of setting up a CP bank proved challenging. Excessive laboratory workloads during a pandemic hamper their ability to conduct MNT, underscoring the need for rapid screening tests. Only a small proportion of our convalescents exhibited high-titre CP, this fraction declining over time because of waning immunity. Strict plasmapheresis criteria further constrained donor eligibility. Establishing a plasma bank requires meticulous planning to maximize efficiency. Detailed insights from current experiences may prove critical in future pandemics before other remedies and vaccines become available.
