Yersinia ruckeri is the causative agent of enteric red mouth disease (ERM, yersiniosis), one of the most important diseases that affects particularly farmed salmonids species. Numerous articles have demonstrated that Y. ruckeri can cause both epizootics and zoonosis. Y. ruckeri shows the ability to survive outside the host in nutrient-limiting environments for long periods due to biofilms forming capacity with adherence to solid supports but also for the adherence to the host tissues. Considering these aspects, the control of Y. ruckeri can be a problem, because of its resistance. Recently, non-thermal plasma activated water (PAW) proved to be active against Gram-negative bacteria and this fact could be also useful in Y. ruckeri control. The purpose of this in vitro study was to test the antimicrobial efficacy of PAW against Y. ruckeri and to explore the ultrastructural changes in these bacteria. Ultrastructural changes in Y. ruckeri cells, probably related to the action of PAW, included modifications in the shape and texture of the outer membrane. These changes in the bacterial membrane have been linked with the inactivation of bacteria by PAW exposure.

Differentiation And Proliferation

Non-thermal plasma (NTP), defined as a partially ionized gas, is an emerging technology with several biomedical applications, including tissue regeneration. In particular, NTP treatment has been shown to activate endogenous biological processes to promote cell regrowth, differentiation, and proliferation in multiple cell types. However, the effects of this therapy on nervous system regeneration have not yet been established. Accordingly, the current study explored the effects of a nanosecond-pulsed dielectric barrier discharge plasma on neural regeneration. Following mechanical trauma in vitro, plasma was applied either directly to (1) astrocytes alone, (2) neurons alone, or (3) neurons or astrocytes in a non-contact co-culture. Remarkably, we identified NTP treatment intensities that accelerated both neurite regeneration and astrocyte regrowth. In astrocyte cultures alone, an exposure of 20–90 mJ accelerated astrocyte re-growth up to three days post-injury, while neurons required lower treatment intensities (≤20 mJ) to achieve sub-lethal outgrowth. Following injury to neurons in non-contact co-culture with astrocytes, 20 mJ exposure of plasma to only neurons or astrocytes resulted in increased neurite regeneration at three days post-treatment compared to the untreated, but no enhancement was observed when both cell types were treated. At day seven, although regeneration further increased, NTP did not elicit a significant increase from the control. However, plasma exposure at higher intensities was found to be injurious, underscoring the need to optimize exposure levels. These results suggest that growth-promoting physiological responses may be elicited via properly calibrated NTP treatment to neurons and/or astrocytes. This could be exploited to accelerate neurite re-growth and modulate neuron-astrocyte interactions, thereby hastening nervous system regeneration.
