How do Brucella bacteria typically enter the human body through the skin during animal handling?
Answer
Through cuts, abrasions, or unnoticed breaks in the skin
The human skin acts as a primary barrier against infection, but this defense is compromised by physical damage. When individuals handle infected animal tissues, fluids, or birth products, the Brucella bacteria can enter the body through cuts, abrasions, or even minor, unnoticed breaks in the skin. This entry method is a particular concern for those in high-risk professions who may work with sharp tools or handle animal remains. Protecting the skin by covering such lesions and maintaining hygiene is an essential component of preventing occupational transmission.
