True or false: Protein in saliva and urine can be a potent allergen.

Protein in saliva and urine can indeed act as potent allergens, particularly in the context of laboratory animals such as rodents, dogs, and cats. These proteins can sensitize individuals with allergies, leading to a range of allergic responses including respiratory issues and skin reactions.

Saliva and urine contain various proteins that may trigger allergic responses. For instance, in cats, the proteins present in their saliva can become airborne when they groom themselves, contributing to allergies in sensitive individuals. Similarly, in rodents, urine proteins have been shown to cause allergic respiratory conditions in humans who come into contact with them.

By acknowledging that these proteins can be significant allergens, it highlights the importance of appropriate handling and environmental controls in laboratories to minimize exposure for individuals prone to allergies. This understanding is critical for laboratory personnel, especially those working closely with animals.
