Hemorrhagic Septicemia Vaccine Suspension

Indications

• Cellulitis
• Abscesses
• Respiratory infections
• Osteomyelitis
• Septic arthritis
• Endocarditis

Dosage

Children: Refer to the BNF for Children for specific dosing recommendations tailored to pediatric patients.

Adults: Refer to specific guidelines or the BNF for appropriate antibiotic dosing based on the type and severity of the infection.

Mechanism of action

Pasteurella multocida produces several virulence factors, including polysaccharide capsules that inhibit phagocytosis, endotoxins that can cause inflammation, and a range of enzymes that facilitate tissue invasion. Antibiotics effective against Pasteurella, such as beta-lactams, inhibit cell wall synthesis, leading to bacterial lysis and death.

Pharmacodynamics

The pharmacodynamics of antibiotics used to treat infections caused by Pasteurella multocida are characterized by their ability to disrupt bacterial cell wall synthesis, inhibit protein synthesis, or interfere with nucleic acid synthesis. The effectiveness of these antibiotics is influenced by factors such as the bacterial strain's susceptibility, the site of infection, and the host's immune response.

Pharmacokinetics

The pharmacokinetics of antibiotics vary depending on the specific drug used to treat infections caused by Pasteurella multocida. Generally, antibiotics are absorbed and distributed throughout the body, with some achieving higher concentrations in tissues and fluids. Metabolism and excretion also vary; for instance, many beta-lactams are primarily excreted unchanged in the urine, necessitating dose adjustments in renal impairment.

Pregnancy

Safety during pregnancy has not been established. Use only if the benefits outweigh the risks.

Breast-feeding

It is unknown whether this drug is excreted in human breast milk. Caution is advised when administering to nursing mothers.

Storage

Store at room temperature, protected from light and moisture. Keep out of reach of children.

Indications

• Cellulitis
• Abscess formation
• Respiratory tract infections
• Septic arthritis
• Osteomyelitis
• Systemic infections following animal bites

Dosage

Children: Refer to specific antibiotic guidelines for dosing based on the type and severity of infection.

Adults: Refer to specific antibiotic guidelines for dosing based on the type and severity of infection.

Mechanism of action

Pasteurella multocida can cause disease by evading host immune responses and producing virulence factors like polysaccharide capsules, endotoxins, and enzymes that disrupt host cell functions. These mechanisms enable the bacteria to adhere to host tissues, invade cells, and evade phagocytosis, contributing to its pathogenicity.

Pharmacodynamics

The pharmacodynamics of Pasteurella infections largely depend on the host's immune response and the antibiotics used for treatment. Pasteurella multocida is typically susceptible to a range of antibiotics, including beta-lactams, tetracyclines, and macrolides, but resistance can occur. Effective management of infections usually requires timely antibiotic therapy, particularly in cases of severe or systemic infection.

Pharmacokinetics

The pharmacokinetics of antibiotics used to treat Pasteurella infections varies by drug. Generally, these antibiotics are absorbed through the gastrointestinal tract, distributed widely in body tissues, and excreted primarily via renal pathways. The choice of antibiotic and its dosing regimen will depend on the severity of the infection, the patient's renal function, and the specific antibiotic used.

Pregnancy

There are no well-controlled studies in pregnant women. Use only if clearly needed.

Breast-feeding

Caution should be exercised when administered to a nursing mother.

Storage

Store at room temperature, away from moisture and heat.
