The rainbow trout production increased more than 100% in the last decade and total rainbow trout production was shown as 107.013 tons according to 2016 statics. According to Federation of European Aquaculture Producer, Turkey was determined as the biggest rainbow trout producer into the European Countries in 2016. Together with high production capacity, a number of outbreaks were reported causing L.anguillarum (Vibriosis). The pathogenesis of L. anguillarum which were experimentally infected in rainbow trout were examined during 15 days in our study. Spreading of agent that was injected with intraperitoneally into tissue and organs were studied by using histopathological methods. The mortality rate of agent was determined above 70% and deaths were seen in 2-3th days of experiment. In addition of these, liver, spleen, kidney and gills were determined as the most affected organs and tissues. In the present study was obtain for original pathological findings of L. anguillarum.

Objectives: In this study, we aimed to investigate whether the positive union effect caused by head trauma could be transferred between individuals. Materials and methods: Seventy-two male rats with an average weight of 375 g were used in this study and divided into four groups including 18 in each group. Group 1 consisted of serum donor rats that were exposed to head trauma, while Group 2 consisted of study rats with long bone fractures that were given the serum obtained from the rats in Group 1, Group 3 included control rats with isolated long bone fractures, and Group 4 included control rats with both head trauma and long bone fractures. For radiological evaluation, the ratio of the width of the callus to the width of the neighboring diaphysis was considered as the callus-to- diaphyseal ratio in the study and control groups. Histopathological and radiological evaluations was made on Days 10, 20, and 30. Results: In evaluation of the radiological data regarding the callus- to-diaphyseal ratio, Group 3 was found to have significantly lower radiological values than Group 4 on Day 10 (p=0.006). Group 2 had significantly higher values than Group 3 (p=0.02). On Day 20, Group 2 exhibited significantly higher radiological values than Group 3 (p=0.004), but lower than Group 4 (p=0.032). As for Day 30, Group 2 exhibited significantly higher radiological values than Group 3, but lower than Group 4 (p=0.001). In the evaluation of the Huo scores obtained for histopathological evaluation, there was no significant difference among the groups on Days 10, 20, and 30 (p=0.295, p=0.569, and p=0.729, respectively). Conclusion: Our study results suggest that the osteoinductive effect after head trauma can be transmitted between individuals by means of serum transfer.

An 11-year-old, male, crossbreed cat was presented for a subcutaneous mass affecting the prescapular region extending to the thoracic vertebrae. The diagnosis of fibrosarcoma was made according to the histopathological examination of the biopsy. Scanning electron microscopy (SEM-EDX) was used to determine the presence of aluminium in the tumor tissue. The owner did not accept further treatment, so the cat died 1 month after diagnosis. This is the first case report from Turkey which diagnoses verified by SEM and has shown that aluminium-containing vaccines may be associated with fibrosarcoma formation. Awareness of the side effects of adjuvants is still not enough level. Determining the frequency of VAS in fibrosarcoma cases will contribute to the increase of life span/survival by protective measures. The aim of this case report is to draw attention to the adjuvant contents of the vaccines and to scrutinize the relationship between vaccine applications and tumor development.
