Effects of dietary lysine supplementation on upper respiratory and ocular disease and detection of infectious organisms in cats within an animal shelter

American Journal of Veterinary Research, 70(11), 1391–1400.

By: T. Drazenovich*, A. Fascetti, H. Westermeyer* , J. Sykes, M. Bannasch, P. Kass, K. Hurley, D. Maggs

MeSH headings : Animal Feed / analysis; Animals; Calicivirus, Feline / isolation & purification; Cat Diseases / microbiology; Cat Diseases / prevention & control; Cats; Chlamydophila Infections / prevention & control; Chlamydophila Infections / veterinary; Dietary Supplements; Eye Infections / microbiology; Eye Infections / prevention & control; Eye Infections / veterinary; Female; Herpesviridae / classification; Herpesviridae Infections / veterinary; Lysine / pharmacology; Male; Respiratory Tract Infections / microbiology; Respiratory Tract Infections / prevention & control; Respiratory Tract Infections / veterinary
TL;DR: Dietary lysine supplementation in the amount used in this study was not a successful means of controlling infectious upper respiratory disease within a cat shelter, and led to increases in disease severity and the incidence of detection of FHV-1 DNA in oropharyngeal or conjunctival mucosal swab specimens at certain time points.
