What bacteria causes Cat Scratch Fever?

Cat Scratch Fever is primarily caused by the bacterium Bartonella henselae. This bacterium is commonly transmitted through bites or scratches from infected cats, particularly those under one year of age, and can also be spread through fleas. When a person is scratched or bitten by an infected cat, Bartonella henselae enters the bloodstream, leading to the symptoms associated with Cat Scratch Fever, including swollen lymph nodes, fever, and fatigue.

Understanding the characteristics of Bartonella henselae is essential because it highlights its unique role in zoonotic diseases, which are infections that can be transmitted from animals to humans. This knowledge emphasizes the importance of public health awareness regarding interactions with pets, especially felines.
