Pediatric feline upper respiratory disease

Abstract

Infectious feline upper respiratory tract disease (URTD) continues to be a widespread and important cause of morbidity and mortality in kittens. Multiple pathogens can contribute to URTD in kittens, and coinfections are common in overcrowded environments and contribute to increased disease severity. Worldwide, the most prevalent pathogens are feline herpesvirus-1 and feline calicivirus. Primary bacterial causes of URTD in cats include Bordetella bronchiseptica, Chlamydia felis, and Mycoplasma species. Streptococcus canis and Streptococcus equi subspecies zooepidemicus occasionally play a role as primary pathogens in shelter situations and catteries. This article reviews the major causes of disease in kittens, and provides an update on treatment and prevention strategies.
