[Chemotherapy of experimental lactational mastitis in mice]

Area of Science:

• Veterinary Medicine
• Microbiology
• Pathology

Background:

• Mastitis is a significant concern in animal health.
• Bacterial infections, particularly Staphylococcus and Proteus, are common causes of mastitis.
• Understanding the differential impact of various pathogens is crucial for effective treatment strategies.

Purpose of the Study:

• To compare the severity of mastitis induced by Staphylococcus, Proteus, and their mixture in a mouse model.
• To investigate the morphological differences between staphylococcal and Proteus mastitis.
• To evaluate the efficacy of a combined antibiotic treatment (kanamycin and fuzidin) for experimental mastitis.

Main Methods:

• A standardized model of experimental lactation mastitis was established in mice.
• Infection was induced using Staphylococcus, Proteus, and a mixture of both pathogens.
• Morphological changes in mammary glands were analyzed.
• The therapeutic effect of kanamycin in combination with fuzidin was assessed.

Main Results:

• Proteus infection resulted in more severe mastitis compared to Staphylococcus infection.
• Distinct morphological differences were observed between staphylococcal and Proteus mastitis.
• The combination of kanamycin and fuzidin demonstrated a pronounced therapeutic effect on experimental mastitis of diverse etiology.

Conclusions:

• Proteus is a more virulent pathogen in experimental lactation mastitis than Staphylococcus.
• Morphological examination can differentiate between staphylococcal and Proteus mastitis.
• Kanamycin and fuzidin combination therapy is effective for treating mastitis caused by various bacterial agents.
