Clostridial myositis, considered to be rare in pet animals, is an acutely fatal toxaemic condition. Some species of clostridia are responsible for necrotic myositis. A 2-year-old male German shepherd dog was admitted with non-weight bearing lameness and massive swelling of the left hind limb. Clostridium perfringens type A with alpha toxin was diagnosed as a pathogenic agent. Based on the history, the bacteria were introduced inside the tissue via contaminated needle following intramuscular injection. Urgent medical therapy followed by surgical intervention was performed. The dog was discharged completely healthy after hospitalization for four weeks. The objective of this report was to describe necrotic myositis in a dog with an emphasis on clinical signs and treatment as well as bacteriological and molecular identification of the micro-organism. Because of the fatal entity of the disease, prompt diagnosis as well as proper and urgent treatment is very important for successful therapy.

Listeria monocytogenes can be found throughout the environment and in many foods. It is associated primarily with meat and animal products. Listeria monocytogenes has become increasingly important as a food-borne pathogen. The aim of this study was to evaluate the effect of microwave (MW) treatment of chicken meat samples which were inoculated with L. monocytogenes. Drumettes of broiler carcasses were soaked in fully growth of L. monocytogenes in Brain-Heart Infusion broth. The swab samples were taken from the inoculated samples, after various times of radiation (10, 20, 30, 40, 50, 60, 70 and 80 sec), using a domestic MW oven at full power. Following exposures, viable counts and surface temperaturemeasurements were performed. The bacterial counts were performed on Oxford agar. The results indicated that equal or longer than 60 sec exposures of chicken portions to MW heating which enhances the median surface temperature more than 74 ˚C could eliminate the superficial contamination of chicken meat with L. monocytogenes. Statistical analysis showed samples with equal or longer than 60 sec exposures to MW heating had significant decrease in population of inoculated bacteria compared with positive control group(p < 0.05). Pearson correlation showed a significant correlation between the bacterial population and temperature of samples due to MW exposure (p < 0.001, r = – 0.879 and r2 = 0.773).
