Figure 1. Animal material and experimental setup, a. M. galloprovincialis, b. Experimental setup, c. V. harveyi injection to the mussel
Figure 3. M. galloprovincialis gill sections, a. Control group, b. PBS group, c. 10 7 cfu/ml V. harveyi injection group, H&E, (GL: Gill lamella, ECV: Enlarged central vein, LJ: Lamellar junction). No significant histopathological findings were found in the digestive gland sections of control and PBS treated mussels. However, an increase in lipofuscin aggregate, focal haemocyte infiltrations, hypertrophy, epithelial deformations were detected in the digestive gland sections of mussels treated with V. harveyi in the post-adductor muscle (Fig. 4).
Figure 4. M. galloprovincialis digestive gland sections, a. Control group, b. PBS group, c. 10 7 cfu/ml V. harveyi injection group, H&E, (DG: Digestive gland, ED: Epithelial deformation, LA: Lipofuscin aggregate, HI: Haemocyte infiltration, H: Hypertrophy). Liu et al. (2014) reported that Vibrio harveyi infection in M. galloprovincialis is sex-specific and causes wide variety of metabolic responses. Parisi et al. (2019) investigated the responses induced in haemolymph and posterior adductor muscle (PAM) after bacterial infection with Vibrio splendidus in M. galloprovincialis samples in vivo. The number of viable intra hemocyte bacteria increased after the first hour after injection, suggesting that an intense phagocytosis occurred as a result of this event, and 24 h clearance was observed. As a result of these observations in the mussel, significant morphological changes in the volume of muscle fibres were observed and muscle tissue organisation was found to improve after 48 hours. Intensive cell cycle activity was observed in PAM after infection with haemocyte infiltration. The results showed that haemolymph is the system responsible for physiological adaptations to maintain homeostasis and immunity against stressful factors such as pathogenicity in mussels. Battistini et al. (2020) conducted microbiological, parasitological and histological analyses of mussels (M, galloprovincialis) from the Gulf of La Spezia in order to see more clearly how human activity and the presence of potentially pathogenic microorganisms affect their health status. In general,

... However, their filter-feeding nature presents unique challenges for post-harvest quality and food safety, as their tissue composition directly reflects seawater conditions and environmental exposures (Colakoglu et al., 2010(Colakoglu et al., , 2011. These organisms can accumulate various risk factors from seawater, including persistent organic pollutants, trace elements, biotoxins, and microbiological agents, potentially affecting both the bivalves themselves and consumers through zoonotic pathways and bioaccumulation (Künili et al., 2021a;Künili et al., 2021b;Balkaya et al., 2023;Künili, 2023;Künili et al., 2023;Çolakoglu et al., 2014, 2020. The post-harvest handling of live mussels involves complex interactions between biological, chemical, and environmental factors that significantly influence product quality and safety. ...
