Zoonotic Bacteria Associated with Cats

Abstract

Background: There are several bacterial pathogens, including Bartonella, and Pasteurella that
have been known to cause human infections from contact with cats. Recently, certain bacteria
have emerged as causes of infection in cats, resulting in transmission to humans.
Objectives: This review presents updated information on the zoonotic bacterial pathogens
associated with cats, with special emphasis on recent reports.
Results: Presently, an increase in the incidence of cat-associated Yersinia pestis human infections
in the western USA has become a concern. In addition, infections due to Mycobacterium
bovis, and Brucella abortus, are being recognized. Also, a number of human infections due to
Campylobacter, Helicobacter, and Salmonella from cats have been documented worldwide. In
addition, spread of bacteria resistant to antimicrobial drugs from cats is becoming a possibility.
Conclusion: Updated information shows that more zoonotic bacteria than previously recognized
are associated with cats worldwide. Immunocompromised persons and young children are
particularly at a risk of developing infection from household cats which are allowed to roam
around outdoors. It is important to incorporate environmental and animal contact considerations
into patient care. With proper handling and precautions, cats can help establish valuable humananimal bonds.
