Objective—To compare measurements of body temperature
obtained with auricular thermometers versus
rectal thermometers in dogs with otitis externa.
Animals—100 client-owned dogs: 50 with and 50
without clinical evidence of otitis externa.
Procedure—Dogs were evaluated for the presence
of otitis externa on the basis of clinical signs, otoscopic
examination, and cytologic evaluation of ear
exudate. Auricular and rectal temperatures were
obtained simultaneously in all dogs prior to and following
Results—There was a high correlation between
auricular and rectal temperatures in dogs with otitis
externa both prior to and after ear manipulation.
Significant differences were not detected in temperature
measurements among dogs with different
degrees of otitis externa.
Conclusions and Clinical Relevance—Auricular
temperature readings obtained by use of an auricular
thermometer in dogs with otitis externa are accurate
measurements of body temperature, compared with
rectal temperature measurements. Temperature
measurements are reliable before and after examination
of the ear canal. (J Am Vet Med Assoc 2002;
Objective—To ascertain whether Malassezia organisms can be detected via cytologic examination and fungal culture of samples from the skin surface of psittacine birds and determine whether the number of those organisms differs between unaffected psittacines and those that have chronic feather-destructive behavior or differs by body region.
Animals—50 unaffected psittacines and 53 psittacines that had feather-destructive behavior.
Procedure—Samples were collected by use of acetate tape strips from the skin of the head, neck, proventer, propatagium, inguinal region, and preen gland area of each bird; 0.5-cm2 sample areas were examined microscopically for yeast, and samples were also incubated on Sabouraud dextrose agar. Polymerase chain reaction assays specific for Malassezia spp, saprophytic fungi, and Candida albicans were performed on DNA prepared from cultured colonies; nested PCR evaluation for Malassezia pachydermatis was then performed.
Results—Microscopically, 63 of 618 (10%) tape-strip samples contained yeast. Thirty cultured colonies were assessed via PCR assays, and all yielded negative results for Malassezia spp; C albicans was identified in 2 colony samples. The numbers of yeast identified microscopically in psittacines with feather-destructive behavior and in unaffected birds did not differ significantly, and numbers did not differ by body region.
Conclusions and Clinical Relevance—Yeast were identified infrequently via cytologic examination of samples from the skin surface of unaffected psittacine birds or those that had chronic feather-destructive behavior. If yeast are identified on the skin of birds with feather-destructive behaviors, fungal culture of skin samples should be performed to identify the organism.
