5 Must Know Facts For Your Next Test

1. CSD primarily affects the lymphatic system, leading to swollen and tender lymph nodes.
2. The causative agent is Bartonella henselae, a gram-negative bacterium.
3. Diagnosis often involves serological tests to detect antibodies against Bartonella henselae.
4. Most cases are self-limiting and resolve without specific treatment, though antibiotics may be prescribed in severe cases.
5. Cats, especially kittens, are common carriers of Bartonella henselae bacteria.
