Helicobacter pylori is a spiral-shaped bacterium, which plays a role in the aetiology of gastric diseases in humans. Non-H. pylori Helicobacter (NHPH) species naturally colonise the stomach of animals and also induce gastric lesions in humans, highlighting their zoonotic importance. We evaluated the gastric bacterial colonisation density and gastric lesions and sought to identify the main phylogenetic groups of the Helicobacter spp. obtained from dogs in the central region of Rio Grande do Sul, Brazil, with this study aiming to investigate the occurrence of Helicobacter spp. in saliva and gastric samples from these dogs. This study included 35 dogs and used analysis such as cytology, histopathology, PCR, rapid urease testing, and phylogenetic analysis. Of the dogs, 94.3% were positive for Helicobacter spp., and these bacteria were present in the stomach of 32 dogs and saliva of eight. Respectively, eight, 15, and nine dogs had mild, moderate, and severe colonisation. Lymphocytic-plasmacytic infiltrate was the main gastric lesion. However, the presence of Helicobacter and the density appeared to be unrelated to the gastric lesions. The samples possessed a high nucleotide identity with remarkably similar sequences among some of the species of NHPH such as H. heilmannii s.s., H. salomonis, H. felis, and H. bizzozeronii. The saliva of domestic dogs, even of those who appear clinically healthy, can cause Helicobacter infection in humans and other animals, with, in these dogs, increased density, occurrence rate, and predominance of NHPH of zoonotic importance being found in the stomach with a lower occurrence of Helicobacter spp. in the saliva.

Este estudo teve como objetivo classificar o perfil clínico dos cães acometidos por leishmaniose no Hospital Veterinário Universitário da Universidade Federal de Santa Maria (HVU-UFSM). Para isso, foram revisados históricos clínicos dos animais atendidos no HVU-UFSM no período de janeiro de 2017 a julho de 2019, por meio dos prontuários dos pacientes. Neste período, 250 animais foram suspeitos para a doença, com resultado positivo para 61 (24,4%) animais. O perfil clínico foi classificado conforme raça, gênero, idade, estado de vacinação e, então, separados de acordo com os sistemas envolvidos: digestório, neuromuscular, multissistêmico, cardiovascular, respiratório, linfático, oftálmico, urinário e tegumentar; sinais clínicos e a presença de doenças concomitantes. Este estudo revelou que a leishmaniose acomete mais animais sem raça definida (SRD), machos com dois a cinco anos de idade e acomete principalmente o sistema tegumentar, seguido do multissistêmico.

The aim of this study was to compare the analgesic effects of continuous infusion of fentanyl, dexmedetomidine, or maropitant. The animals received pre-anesthetic medication and anesthetic induction. Subsequently, continuous infusion of drugs was instituted, distributed in the following groups: fentanyl, dexmedetomidine, and maropitant. During the surgical procedure, the analgesic effects were evaluated by recording the cardiorespiratory parameters at the moments of greatest pain stimulus. When evaluating analgesic effects, the maropitant group showed greater stability in cardiorespiratory parameters compared to the fentanyl and dexmedetomidine group. From this study, it is suggested that continuous infusion of maropitant has analgesic effects similar to fentanyl and greater than dexmedetomidine.
