ไฝ็จๆฉๅถ: SPL functions as an immunomodulator that specifically enhances **cell-mediated immunity** (Th1 immune response). * **Cytokine Stimulation:** It stimulates the production of key pro-inflammatory and immunoregulatory cytokines, including **Tumor Necrosis Factor (TNF-ฮฑ)**, **Interleukin-6 (IL-6)**, and **Interferon-gamma (IFN-ฮณ)**. * **Mechanism:** By upregulating IFN-ฮณ and TNF-ฮฑ, SPL enhances the phagocytic and bactericidal activities of macrophages and neutrophils โ leading to improved clearance of intracellular and extracellular staphylococcal organisms from the skin. * **Protein A Role:** The presence of staphylococcal Protein A acts as a potent B-cell superantigen and immunogen, further stimulating a robust host immune response against staphylococcal antigens.

- Labeled indications (Highly allergic patients) ยท Skin test with 0.05-0.1 mL intradermally. Therapy: Initially, 0.2 mL SC, then incremental increases of 0.2 mL once a week to 1 mL (a total of 5 injections). Then continue at 1 mL SC weekly for approximately 10-12 weeks. ยท SC/ID ยท Weekly ยท 10-12 weeks ยท Concomitant antibiotic therapy is recommended for an initial 4-6 week period. Maximum dose should be decreased in small dogs and can be increased cautiously, if necessary, in large dogs to 1.5 mL.
- Labeled indications (Non-allergic patients) ยท 0.5 mL SC twice weekly for 10-12 weeks, then 0.5-1 mL every 1-2 weeks. ยท SC ยท Twice weekly then every 1-2 weeks ยท 10-12 weeks initial, then maintenance ยท Concomitant antibiotic therapy is recommended for an initial 4-6 week period.
- Idiopathic, recurrent pyoderma ยท 0.5 mL SC twice weekly for 10-12 weeks, then tapered to effect. ยท SC ยท Twice weekly ยท 10-12 weeks then tapered ยท This agent is rarely needed, because in most cases, an underlying cause can be identified and treated.
- Chronic recurrent idiopathic pyoderma ยท Injections are administered twice weekly (0.5 mL) and slowly reduced to 0.5 mL every 2 weeks. ยท SC ยท Twice weekly then reduced ยท Ongoing ยท Pyoderma needs to be under control as this product is not a substitute for antibiotics.

- Post vaccine-type reactions (fever, malaise)
- Injection site reactions (redness, itching, swelling occurring 2-3 hours post-injection and persisting up to 3 days)
- Systemic hypersensitivity reactions (weakness, vomiting, diarrhea, severe itching, rapid breathing, fatigue/lassitude)

- Clinical efficacy (resolution of pyoderma)
- Local injection site reactions (redness, swelling, itching)
- Systemic hypersensitivity reactions (anaphylaxis, vomiting, weakness)
้้
No specific information was located regarding acute toxicity. Other than an increased risk for local or systemic hypersensitivity reactions, significant morbidity appears unlikely. Should an anaphylactic-type reaction occur, treat supportively; the manufacturer recommends **epinephrine** and **atropine** as antidotes.
