  Background: The aim of this study is to examine the microbiological, clinical, physiological and pathological findings of natural polymicrobial infection developing in a wistar rat colony under long-term observation. Methods: In this study, 70 male Wistar albino rats, 3 years old, raised by conventional methods and housed in a cage environment were used. Thirteen rats with clinical symptoms such as torticollis and rotation were sacrificed for microbiological and histopathological examination after 14 days. For microbiological examination, the rapid diagnostic kit BBL Crystal system was used to identify bacterial agents in tissue and stool samples and the traditional culture method was used for isolation. Result: As a result of microbiological analysis, the rarely isolated Staphylococcus capitis (S. capitis) was isolated. Different Staphylococcus spp. It has been determined that the species can cause suppurative meningoencephalitis as well as septicemia in the brains of experimental animals., it is thought that polymicrobial infection will be useful for the identification of bacterial agents and infection prevention and treatment strategies.

  The aim of the present study was to evaluate the treatment potential of Punica granatum L. peel powder in an experimentally induced sepsis model in rats. Sepsis was induced in 10-week-old, male, Wistar Albino (n=24) rats. The animals were divided into four groups: Sham-operated (S) Group, Control (C) Group, Treatment-1 (T1) Group, and Treatment-2 (T2) Group. To induce the sepsis model, the cecal ligation and puncture procedure was performed. The P. granatum peel powder (200 mg/kg; per os) was applied one hour before (T1) and 10 hours after (T2) surgery in a volume of 2 mL. At the end of the experimental procedure, microbial and histopathological analyses were performed. The histopathological scores on the liver, lungs, heart, kidney, spleen, and pancreas were evaluated. Escherichia coli, Staphylococcus aureus and E. coli + S. aureus were isolated from blood cultures. Severe bacteria were detected in the blood of the group C animals. It was found that there were fewer bacteria in groups T1 (n=2) and T2 (n=4) compared with group C. There were no lesions in the pancreas tissues of any groups. Vascular changes, degeneration, and necrosis were common in the organs in all cases of group C compared to group S. The findings in group T1 were similar to those in group C, however, it was seen in fewer animals. It was determined that there was a general improvement in group T2, and in addition the existing lesions were moderate in severity. In conclusion, P. granatum L. peel powder prevented CLP-induced lung injury in experimental rats. Thus, P. granatum L. peel powder may be an alternative therapeutic agent against lung tissue injury induced by sepsis. The recovery from inflammation was better in group T2 than in the other groups. According to the results of the current study, P. granatum peel powder was found to be effective in the treatment of sepsis with antimicrobial and anti-inflammatory functions.
