The veterinarian is exposed to a number of factors in their daily work that can deteriorate their mental and emotional health. The objective of this research was to evaluate stress and burnout through the application of two questionnaires: Test "Maslach Burnout Inventory" and Test "Perceived Stress Scale", and determine the stress factors in veterinarians who practice their profession in the Valle de los Chillos in the city of Quito.   The results found in the Maslach Burnout Inventory (MBI) Test performed on Veterinarians working in the city of Quito in the Valley of the Chillos, show the relationship between the different variables studied (gender and age) and emotional fatigue. Che distribution of positive cases (signs of Burnout Syndrome) were 52% positive.  More than half of the respondents presented signs of Burnout Syndrome which suggests a greater tendency to emotional fatigue and depersonalization.

Knowledge of the embryonic development of species such as quail is important for our understanding of its production and reproduction. Quail provides a practical solution to the animal protein shortage problem in developing countries and is an excellent alternative to chicken (Shanaway, 1994). This study evaluated quail embryonic viability by comparing the main morphological changes that occur over the development in a homemade incubator with previous data; the incubator was built using easily accessible and low-cost materials, which allows small producers and communities to develop quail farms as an activity to increase income or even produce a source of animal protein for the community in the Brazilian Amazon region. The homemade incubator measured 40 cm × 42 cm × 32 cm and was constructed with wooden boards, a digital thermostat, and an incandescent lamp. A total of 24 fertile eggs were incubated at a temperature of 37.5 °C and 60% relative humidity; age “0” was set at the start of incubation. Two eggs were opened on each day of development, starting from day 5 to day 16 of incubation. After gently opening the eggs, the embryos were removed, separated from the placenta and amniotic fluid, washed with running water, and weighed on a digital scale (SHIMADZU AUY 220 brand and UNI BLOC model). Crown-rump length and other measurements were performed with a digital caliper and the morphological structures were observed using a stereomicroscope (NOVA brand and NOVA ZTX-E model). All eggs opened contained live embryos, indicating that the homemade incubator temperature, relative humidity, and manual turning were adequate to maintain the quail's viability. The morphometric data of the embryos at different developmental time points were similar to those described in the literature. Embryos weighed 0.0069 g at day 5 and 4.7863 g at day 16, and the crown-rump length (CRL) means were 0.368 cm and 3.657 cm, respectively. Weight and CRL increased by 0.434 g and 2.593 cm per day of incubation, respectively. In conclusion, after 16 days of incubation in a homemade incubator, the embryos presented all phases of the development cycle, with appropriate development of weight and height based on the days of incubation without anomaly or external interference. These findings demonstrate that the homemade incubator does not alter the embryonic development of quail embryos in the Brazilian Amazon region.

Nocardiosis is an infection caused by ubiquitous opportunistic bacteria and is rare in felines. In retrospective studies of the infection in the species, pyothorax was found in only about 5% of the cases described, with the most frequent forms being cutaneous and subcutaneous. This report describes Nocardia spp. as an etiologic agent of pyothorax in a feline leukemia virus (FeLV)-positive female cat. A 10-year-old female mixed-breed cat, positive for FeLV, with chronic kidney disease IRIS stage 2, was examined with a severe dyspneic onset, suspected of pleural effusion. It also had skin lesions in the interscapular region. The patient underwent thoracentesis, and a dense, creamy, fetid, and flocculated liquid was collected. Radiography was performed after draining the pleural fluid, which showed images suggestive of atelectasis of the left lung lobes and pneumonia. The collected material was sent for analysis, which found that it was a septic exudate. In addition, it was referred for bacterial culture in a special medium due to suspicion of nocardiosis. Long-term treatment with amoxicillin + clavulanic acid resolved the clinical case.

We present the case of a five-year-old intact mixed breed male dog with hemorrhagic prostatic cysts. The patient presented with hematuria, dysesthesia, and pain on abdominal palpation. Abdominal ultrasound, hematology, urinalysis, and biochemical evaluation tests were subsequently conducted. Laboratory tests revealed cloudy urine with bacteria, and countless red blood cells. On ultrasound examination, the prostate was severely enlarged, with heterogeneous and reduced parenchyma, surrounding a large cavity filled with anechoic material with moderate cellularity. The urinary bladder was markedly distended and had a round, hypoechogenic structure in the lumen. The patient was hospitalized and had significant, irreversible worsening of the clinical symptoms and died. Subsequently, necropsy of the patient was performed and a histopathological diagnosis of benign prostatic hyperplasia associated with the presence of a prostatic hemorrhagic cyst, prostatitis, and chronic cystitis with an intraluminal blood clot was made. To the best of our knowledge, this is the first report to describe the occurrence of a hemorrhagic cyst in a canine prostate, thus bringing important information from clinical and imaging findings to the veterinary routine.

The risk of bovine cysticercosis is mutable over time, since population habits, local infrastructure, and bovine herd size change through the years. Hence, the aim of this study was to update the risk map of bovine cysticercosis occurrence in Espírito Santo State, Brazil, by choosing the following risk factors: inadequate sewer service; bovine population per municipality; risk of flooding; and land use and occupation, examined with a mathematical model using the GIS program ArcGis 10.5. The risk map of occurrence demonstrated that the state is composed of 12.8, 24.5, 36.2 and 26.5% of areas of very high, high, medium, and low risk, respectively. The northern area stood out for areas of very high risk, with the cities of Linhares and São Mateus accounting for 99% of the area with this classification. Of the state’s 78 municipalities, 15 had a portion of their territory with very high risk, 11 had over 50% of the territory with high risk and all except Irupi (100% of low risk) had some percentage of medium risk. These findings demonstrate the areas where actions to prevent bovine cysticercosis should be preferentially conducted.

Canine Parvovirus infection is a disease caused by Canine Parvovirus (CPV) that results in hemorrhagic gastroenteritis and secondary infections, mainly in puppies between six weeks and six months old that are not immunized. Since there is no specific treatment for the condition, supportive therapy based on antibiotics, antiemetics, and non-steroidal anti-inflammatory drugs is traditionally used. Ozone therapy is an economical treatment that has bactericidal, fungicidal, and antiviral properties, besides promoting oxygenation and tissue regeneration, as well as anti-inflammatory and analgesic effects, and was used as a complementary therapy in this study. Therefore, four mixed-breed dogs, aged between 2 and 3 months, with no previous immunization against CPV and testing positive for the virus in a rapid test were selected. The animals were randomly distributed into two groups, being 1: the control group (n=2) that received only supportive treatment; and 2: the experimental group (n=2), that in addition to conventional therapy received intravenously 500 mL of ozonized Ringer’s Lactate solution. Before treatment and after 24 and 48 hours, the following clinical signs were evaluated: episodes of emesis and diarrhea, weight, hydration, blood glucose level, abdominal pain, and blood count. One control group animal died within the first hours of hospitalization. Both animals in the experimental group presented faster resolution of diarrheal episodes and shorter hospitalization time when compared to the surviving animal that received only supportive treatment. Although further studies are needed, ozone therapy showed promising results for the treatment of canine parvovirus.

Various animal models are used for research; however, non-human primates are well suited for biomedical research owing to their genetic homology with humans. The objective of this research was the anatomical characterization of red howler’s kidneys in view of the scarcity of information in the literature. Protocols were approved by the Committee for Ethics in the Use of Animals at the Federal Rural University of Rio de Janeiro (number 018/2017). The study was conducted at the Laboratory of Teaching and Research in Domestic and Wild Animal Morphology, Federal Rural University of Rio de Janeiro. Specimens of Alouatta guariba clamitans were collected from the Serra dos Órgãos National Park road in Rio de Janeiro and subsequently frozen. Four adult cadavers (two males and two females) were used, identified, and injected with a 10% formaldehyde solution. Later, the specimens were dissected, and measurements and topography of the kidneys and renal vessels were recorded. The kidneys of A. g. clamitans resemble a “bean seed,” with a smooth surface. The longitudinal section shows two distinct regions, cortical and medullary; in addition, the kidneys are unipyramidal. The renal arteries emerged from the abdominal aorta as a single vessel posterior to the renal veins. The renal veins drained directly into the caudal vena cava as a single vessel in all specimens.
