This study aimed to evaluate the effects of tramadol on tear production, intraocular pressure (IOP) and pupil diameter (PD) in healthy dogs. Dogs were randomly assigned to receive 4mg kg-1 (n=11) and 6mg kg-1 (n=11) of tramadol hydrochloride intramuscularly. Tear production (Schirmer tear test, STT-1), IOP (applanation tonometry) and the PD (electronic pachymetry) were assessed before, 30 and 60 minutes after administration of tramadol. Data were compared by analysis of variance for repeated measures (P<0.05). Parameters evaluated before, at 30 and 60min, in dogs treated with 4 and 6mg kg-1, were respectively: (STT-1) 22.50±3.38, 21.14±3.94 and 21.09±2.99mm min-1; and 23.05±3.73,22.64±3.76 and 22.82±3.25mm min-1. (IOP) 18.14±2.68, 17.68±2.59 and 18.23±3.84mmHg; and 19.05±2.27, 18.91±2.74 and 17.64±2.34mmHg. (PD) 6.71±0.65, 7.22±1.42 and 6.90±1.39mm; and 6.25±1.08, 6.80±1.27 and 6.49±0.90mm. All parameters evaluated did not change significantly among time points and dose regimen. Based on the conditions under which the experiments were conducted, tramadol did not affect tear production, IOP and PD in dogs, and could be used as a preoperative analgesic for intraocular surgery and pain control for any cause in patients affected by uveitis, glaucoma and keratoconjunctivitis sicca. © 2015 Universidade Federal de Santa Maria.

Toxoplasma gondii, obligate intracellular parasite, like in other species, is very common in dogs. Its diagnosis is difficult because the clinical signs that can be confused with other illnesses. The use of PCR in diagnosis has been growing and has helped in the detection of the parasite at different stages of the disease. We collected blood samples from dogs in the city of Cuiabá and subjected to molecular analysis for the detection of DNA of T. gondii. These data were related to the intake of raw meat of these animals. The result showed that 17,5% had a diet associated with raw meat, but only 12,7% were positive by PCR. The intake of raw foods and undercooked is a route of infection that must be highlighted by having a zoonotic and highly relevant to public health.

The aim of this study was to identify the Leishmania species in Jaciara dogs; visceral leishmaniasis (VL) is endemic in the county of Jaciara. A comparison among the PCR results for the spleen, bone marrow, skin and blood of 101 dogs with VL-reactive serum were evaluated. Spleen tissue showed the highest detection percentage, followed by bone marrow. In 97 (96.04%) dogs, the Leishmania DNA detected was confirmed as L. chagasi, emphasizing the importance of aetiological identifications in sympatric areas with other trypanosomatids. © 2015, Universidade Federal de Santa Maria.
