Vets diagnose bacterial infections in pets through a combination of physical exams, clinical history, and laboratory tests. Key methods include microscopic cytology of skin/ear swabs, blood tests (CBC) to detect infection, and bacterial cultures to identify specific bacteria and determine antibiotic susceptibility.

What are the signs of possible serious bacterial infection?

Clinical signs of PSBI are defined as:

• fast breathing (respiratory rate ≥ 60 breaths/minute)
• severe chest in-drawing.
• fever (temperature ≥ 38 °C)
• hypothermia (temperature < 35.5 °C)
• no movement at all or movement only on stimulation.
• feeding poorly or not feeding at all.
• convulsions.

How do you rule out a bacterial infection?

What test confirms bacterial infection?
