Beta hemolytic streptococcal infections, usually of group G and C, were identified in red foxes in France. In a study of 31 animals, septicemia and jaundice were found to be the main signs of the disease. Gross and microscopic lesions consisted of generalized inflammation of viscera and joints, jaundice, cellulitis and abscesses of spleen, liver, lungs and kidneys. The disease was reproduced in foxes by intramuscular inoculation of less than the minimal quantity of bacteria lethal to mice. When challenged, recovered animals were resistant to infection that proved to be lethal to control animals.

Background: Bacterial contamination of medical equipment is a significant risk in both human and veterinary medicine, leading to potential cross-contamination between clinicians, technicians, patients, and healthcare professionals. Pathogens can persist on surfaces, resulting in healthcare-associated infections. Tonometry used to measure intraocular pressure for diagnosing conditions like glaucoma and uveitis, is crucial in both human and veterinary care.

Purpose Of Review: The aim is to discuss the evidence and recent literature on the role of older antibiotics in the treatment of skin and soft tissue infections (SSTIs).
Recent Findings: The choice of therapy for SSTIs is complicated in view of the rising antimicrobial resistance (AMR) and the availability of new antibiotics. SSTIs are predominantly caused by Staphylococcus aureus and beta-hemolytic streptococci, but other organisms can be involved in patients with comorbidities or post trauma.

Anamnesis And Clinical Examination: A 59-year-old female patient with an unremarkable medical history presented with watery diarrhea, severe lower abdominal pain, and fever for approximately 7 days. Physical examination revealed a distended abdomen, bowel sounds were absent, and there was an acute abdomen with generalized guarding and significantly elevated inflammatory markers.
Diagnosis: Abdominal computed tomography showed significant ascites and signs of peritonitis.

Article Synopsis
- - This study is the first to investigate Vibrio parahaemolyticus from migrating birds in Egypt, finding that 13.75% of the 80 samples were contaminated with this pathogen.
- - Most isolates showed genetic similarities to human and shrimp strains, carrying multiple virulence genes and demonstrating antibiotic-resistance, including multidrug resistance (MDR) and extensively drug-resistant (XDR) traits.
- - The research highlights a dangerous health risk due to the identification of resistant V. parahaemolyticus strains in birds, raising concerns about zoonotic transmission to humans.
