Summary:

Lymphocytic/plasmacytic colitis was diagnosed in 14 cats during a 5-year period. Purebred cats were affected significantly (P < 0.001) more often than were nonpurebred cats. Six cats were male and 8 were female. Mean age at onset of clinical signs was 5.1 years (range, 0.5 to 9 years). Hematochezia, observed in 13 cats, was the most commonly reported sign; diarrhea was reported in 11 cats. Mildly high serum alanine transaminase activity and hypokalemia were frequent biochemical abnormalities. Campylobacter sp was cultured from the feces of 1 cat. On endoscopic examination, petechia and hyperemia of the colonic mucosa were detected in 7 of 8 cats. Cats were initially treated with dietary management alone or with a combination of dietary and pharmacologic management. Clinical signs in 7 of 11 treated cats completely resolved, whereas signs in 3 cats were considered improved. One cat was euthanatized when an inadequate response to treatment was observed. Most cats were eventually maintained on dietary management alone.

Summary

Over a 5-year period, lymphocytic/plasmacytic gastroenteritis was diagnosed in 14 cats. Purebred cats were affected significantly (P < 0.025) more often than nonpurebred cats. Mean age at onset of clinical signs was 6.8 years (range, 1 to 13 years); 11 cats were male. Vomiting and weight loss, each reported in 10 of 14 cats, were the most common clinical signs. Diarrhea was reported in 7 of 14 cats. Alopecia was found in 4 of 14 cats. High hepatic enzyme activities and low plasma protein concentrations were frequent biochemical findings. Hyperemia, hemorrhage, and a roughened or “cobblestone” mucosa were visualized by endoscopy in only 2 of 8 cats with duodenal disease and in 2 of 5 cats with gastric disease. Lymphocytic/plasmacytic inflammation was detected in biopsy specimens from the stomach or duodenum or both in all cats; the duodenum was affected most commonly. Degree of inflammation frequently varied among gastric, duodenal, and colonic specimens from the same cat. Glucocorticoid treatment and dietary management adequately controlled clinical signs in 7 cats, but treatment was ineffective in 6 cats, 5 of which were euthanatized because of severity of clinical signs.

Abstract

Objective—To evaluate whether the application of steam to a variety of surface types in a veterinary hospital would effectively reduce the number of bacteria.

Sample—5 surface types.

Procedures—Steam was applied as a surface treatment for disinfection to 18 test sites of 5 surface types in a veterinary hospital. A pretreatment sample was obtained by collection of a swab specimen from the left side of each defined test surface. Steam disinfection was performed on the right side of each test surface, and a posttreatment sample was then collected in the same manner from the treated (right) side of each test surface. Total bacteria for pretreatment and posttreatment samples were quantified by heterotrophic plate counts and for Staphylococcus aureus, Pseudomonas spp, and total coliforms by counts on selective media.

Results—Significant reductions were observed in heterotrophic plate counts after steam application to dog runs and dog kennel floors. A significant reduction in counts of Pseudomonas spp was observed after steam application to tub sinks. Bacterial counts were reduced, but not significantly, on most other test surfaces that had adequate pretreatment counts for quantification.

Conclusions and Clinical Relevance—Development of health-care–associated infections is of increasing concern in human and veterinary medicine. The application of steam significantly reduced bacterial numbers on a variety of surfaces within a veterinary facility. Steam disinfection may prove to be an alternative or adjunct to chemical disinfection within veterinary practices.
