Abstract:

Yorkshire terrier is one of the most popular of canine breeds in the world. Numerous health problems are known in the predisposition of this dog such as allergodermatitis, portosystemic shunt, juvenile hypoglycemia, tracheal collapse, persistent puppy teeth, hypoplasia of dens, distichiae, Legg-Carvé-Perthes syndrome, luxating patellas and haemorrhagic (gastro)enteritis. Nowadays more and more dogs are brought to small animal clinics suffering from chronic, often bloody diarrhea, and in many cases an exact diagnosis can’t be set up, so they are simply treated with symptomatic and supportive therapy (antibiotics, intestinal protectants, adsorbents, antacids and a specific diet). In the veterinary references many causes are mentioned of haemorrhagic enteritis inducing diarrhea (bacteria and their toxins, viruses, parasites, fungal infections, toxins, drugs, tumors, some specific enteritis as SIBO, IBD etc.) Our aim was to performe a retrospectiv study about this diseases in yorkshire terriers.

We examined the fecal samples of 30 yorkshire terriers to establish the diagnosis, the presence and the prevalence of intestinal diseases. We got the samples from the DUO-BAKT Laboratory and from the Ebcsont Beforr Small Animal Clinic. We tested the stool’s color, consistency, shape, odor and the presence of mucus or blood in it. In the laboratory microbiological, parasitical and other specific examinations (such as Clostridium difficile toxin ELISA) were performed. We also prepared four fecal smears (Diff Quik panoptic, Gram, acid and starch stain) for the cytological examination and in 15 cases parvovirus PCR was made by the Immunological Department of the Veterinary Faculty.

From the 30 samples we found 17 (56,7%) with dysbacteriosis, in 14 cases (46,7%) we observed cytologically typical figure of bacteria (Campylobacter, Spirocheta, Clostridium), in 9 of 30 (30%) the lack of the normal flora, in 2 (6,7%) the lack of the normal flora with overgrowth of coccoid bacteria was found. In 4 cases (13,3%) steatorrhea, in 2 samples (6,7%) starch indigestion and in 2 cases (6,7%) protein indigestion were realised. Other findings were: 2 cases (6,7%) with parasites (Giardia, Isospora), 2 (6,7%) with serious overgrowth of fungals, and 0 with bacterial toxins. In 2 (6,7%) cases we didn’t find a specific diagnosis. 15 samples were examined for parvovirus with PCR and 7 (46,7%) of them were CPV2 positive and 8 (53,3%) negative.

We also assumed that in cases where we couldn’t set up a specific diagnosis, stress could have played a significant role in the pathophysiology of the diarrhea.
