Sf. Lent et al., COINCIDENT ENTERIC CRYPTOSPORIDIOSIS AND LYMPHOSARCOMA IN A CAT WITH DIARRHEA, The Journal of the American Animal Hospital Association, 29(6), 1993, pp. 492-496
A 13-year-old, neutered male, domestic shorthair cat was presented wit
h the complaint of chronic, malodorous diarrhea. Cryptosporidium spp.
oocysts were identified microscopically in direct fecal smears stained
by a modified acid-fast technique. Results of bacteriological, serolo
gical, and clinicopathological tests revealed no other cause for the p
ersistent diarrhea. Clinical improvement was associated with the feedi
ng of a diet that was reduced in fat and protein. Coprophagia was init
ially assumed to be the source of persistent cryptosporidiosis. The ca
t was euthanized due to recurrent diarrhea, approximately three months
after initial presentation. Cryptosporidium spp. oocysts were again d
etected in direct fecal smears obtained antemortem. Postmortem examina
tion revealed intestinal lymphosarcoma.
