Análise qualitativa da reação colorimétrica do teste de urease em saliva de cães

Abstract

Helicobacterioses are zoonoses transmitted by agents of the genus Helicobacter, which colonize the gastrointestinal tract of humans and animals, which can cause a chronic gastric infection and whose main characteristic is the production of urease.The mechanism of transmission has not yet been fully elucidated, but it’s suggested that it can occur through the oral-oral and fecal-oral routes, since this bacterium may be present in the saliva and dental plaque, and the transmission can occur through licking the dog to the tutor on a day to day basis.The objective of this study was to evaluate the presence of Helicobacter sp. bacteria in saliva of dogs through the colorimetric reaction of the urease test.A total of 28 saliva samples were collected from the dogs and their tutors, which were tested using the Urease® test, and surveys were conducted through open and closed questions about the relationship between tutors and their dogs, as well as the management used in the breeding. Samples from 17 dogs (60.71%) and from 3 tutors (12%) were reagents. Male dogs presented higher incidence than females, with 58.82% and 41.18%, respectively. It is concluded that Helicobacter sp. may be present in the saliva of dogs exhibiting vomiting, and that urease test can be used as a means of presumptive diagnosis.
