The present study investigated veterinarians’ perceptions of bioethics and animal welfare training. Participants were divided in two groups: Group 1 graduated in or before 2003, and Group 2 graduated after 2003. One hundred forty participants completed the questionnaire: 62 (44.3%) from Group 1 and 78 (55.7%) from Group 2. One participant (1.6%) in Group 1 and 8 participants (10.2%) in Group 2 were taught bioethics as an elective or required course before graduating (p=0.003). Fifty-nine participants (95.2%) from Group 1 and 75 (96.2%) from Group 2 believed thata bioethics course should be required to graduate (p=0.959). Four participants (6.4%) from Group 1 and 24 (30.8%) from Group 2 were taught animal welfare as an elective or required course before graduating (p=0.003). Fifty-seven participants (91.9%) from Group 1 and 77 (98.7%) from Group 2 believed that animal welfare should be requiredto graduate(p=0.959). All participants considered both subjects highly relevant to the profession. Most participants were not taught bioethics or animal welfare courses before graduating; however, the availability of these courses increased after 2003. It was concluded that more emphasis should be given to teaching bioethics and animal welfare in veterinary undergraduate training.

Demodicosis is a parasitic dermatopathy, resulting from the excessive proliferation of Demodex mites. The rateat which this disease is encountered in the pet clinic is high, despite recent advances in the treatment ofthe disease. The aim of this study, which was conducted in Brazil, was to analyze the efficacy of fluralanerin the treatment of demodicosis in dogs. Fifteen dogs with generalized demodicosis that were diagnosedwith Demodex sp. mites from skin scraping were included. All animals were treated with fluralaner at adose of 25 mg/kg, following the manufacturer’s recommendations for the treatment of ectoparasites.The effectiveness of the treatment was evaluated based on clinical improvement of the animals andthe time required to obtain two consecutive negative skin scrapes 30 days apart (parasitological cure).The main clinical signs observed were alopecia (100%; 15/15); erythema (86.7%; 10/15); and hypotrichosis,papule, crusts, hyperpigmentation, and hyperkeratosis (26.7%; 4/15). Of the 15 animals evaluated, two ofthem were excluded for not returning for the second evaluation in 60 days, although they had the firstnegative skin scrape. After 30 days, six (46.2%) from 13 animals that concluded the study presented thefirst negative skin scraping. At the end of the study, all dogs presented parasitological cure and clinicalimprovement, except for three animals. One for developing atopic dermatitis and two that lived in ananimal shelter. In conclusion, a single oral dose of fluralaner is effective in the treatment of generalizeddemodicosis in dogs.

Wild birds host a wide variety of endoparasites. These endoparasites are important because they cancause serious infections in birds. The present study aimed to conduct a copro-parasitological survey inwild birds captured in the Cazumba-Iracema Extractive Reserve (Resex) located in the county of SenaMadureira, State of Acre, in northern Brazil. In order to capture these birds, ornithological mist nets wereplaced in different ecosystems of the Resex. Captured birds were identified and held in cloth sacks for30 min. Fecal samples, from each bird, were collected if available. Direct examination and spontaneoussedimentation were used to analyze these samples. The prevalence rate of endoparasite infections in thefecal samples examined was 70.58% (72/102). Oocysts and cysts of protozoa were detected in 69.44%(50/72) of the samples, whereas helminth eggs were seen in 75.00% (54/72) of these specimens. To date,the southwest of the Amazon rainforest, northern Brazil, is a poorly explored area that warrants furtherresearch on the parasitic fauna of wildlife.

Adenocarcinomas are malignant epithelial neoplasms of glandular nature and have been reported in many organs of companion animals including the lungs, thyroid, prostate, mammary glands, gallbladder, pancreas, esophagus, stomach, and intestine. In felines, reports of such neoplasms in the genitalia and associated glands are very rare and have a reserved prognosis. There are no reports in the veterinary literature describing this type of neoplasia affecting the foreskin of cats. Cytological analysis and histopathological evaluation of incisional or excisional biopsy samples can confirm the diagnosis of preputial neoplasms. The gold standard treatment consists of surgical excision of the neoplasm. In the present report, a 16-year-old male Brazilian shorthair feline was referred to the Surgical Clinic service of the Companion Animal Veterinary Hospital of UFRRJ, with a major complaint of increased volume and ulceration in the preputial and penile region with slow growth. The animal experienced dysuria, urinary retention, and pollakiuria. It had a history of recurrent urinary obstructions and urolithiasis. A penile urethrostomy was performed, and the mass was histopathologically and microbiologically analyzed due to a suspicion of fungal or neoplastic involvement. Histopathological examination showed the presence of tubular adenocarcinomas. Chemotherapy treatment was suggested in the immediate postoperative period, but it was not performed per the owner’s request. One year after the foreskin resection and creation of a new urethral stoma, a new mass was found in the perineal region, and the animal died one week later.

Trypanosoma rhipicephalis Marotta et al. (2018) is a species isolated from Rhipicephalus microplus ticks collected from native bovine Seropedica, in the state of Rio de Janeiro. This study aimed to investigate the interaction of the tick Rhipicephalus sanguineus s. l. with T. rhipicephalis by in vitro artificial feeding. Eight females of R. sanguineus s. l. partially fed on rabbits. Tick infection was performed by an artificial feeding system using plastic tips for 12 hours. Canine blood used for feeding the ticks test group was previously infected with T. rhipicephalis 108/mL. The hemolymph smear test was performed in all females after experimental infection. The daily posture was collected and organized in pools of each female per posture day. The eggs were divided into three groups, the first group for eggs PCR, the second for hatching and larval PCR, and the third group of eggs for isolation in cell culture. The evaluation of the presence of DNA in the macerated eggs of experimentally infected ticks showed two positive PCR samples. The evaluation of the presence of DNA in experimentally infected females showed all samples tested positive. For the hemolymph test, tick number 7 presented epimastigote developmental forms and amastigotes of T. rhipicephalis. Experimental infection by artificial feeding proved to be a suitable tool to study the interaction of T. rhipicephalis in R. sanguineus s. l. ticks. The results show the transovarial transmission of T. rhipicephalis by R. sanguineus s. l., as well as the interaction of the protozoan in the organism of this tick species.

Over the past years, the number of neoplasm cases reported in nonhuman primates have considerably increased, with hepatocellular tumors reported in several species. Here a case report of extrahepatic cholangiocarcinoma in an adult male Black Howler Monkey (Alouatta caraya) is presented. The animal, kept as pet, was admitted at Veterinary Hospital presented clinical signs of cholestasis. After unsuccessful drug treatment, the animal was submitted to a cholecystoduodenostomy. During the surgical procedure, the hepatobiliary system was meticulously observed. The liver showed no macroscopic alterations, however, there was a solid mass throughout the common bile duct. Biopsy specimens were collected from the bile duct mass, liver and gallbladder for histological and immunohistochemical evaluations. Histological examination of the liver showed diffuse accentuated vacuolization and necrosis, besides hemosiderin accumulation inside hepatocytes. In the portal region, there was an accentuated proliferation of biliary ducts, which presented replete with bilirubin. Discrete neutrophilic inflammatory infiltrate and fibrosis were also observed. The bile duct mass showed a cellular proliferation of epithelial origin, confirmed by immunohistochemical analysis. The arrangement, characteristics and growth pattern of these cells revealed a malignant neoplasm. Despite the success of the procedure, the animal died hours later. Cholangiocarcinomas generally present high mortality rates, since its late clinical presentation make the treatments ineffective due to its large extensions at the time of diagnosis. The owner did not allow the necropsy, therefore the presence of other neoplasms and important organ alterations, which may be aggravated the patient's clinical condition, were not confirmed.

The present study sought to characterize the phenomena involved in the histopathology of rabies and to assess the presence and amount of viral antigen in situ in different brain regions of naturally infected equines and bovines. The histopathological examination showed several changes due to inflammation, being most often infected cells neurons. The neuronal degeneration involved 100% of cases, in addition to a diffuse lymphocytic Infiltration and gliosis, characterized by vasculitis and perivasculitis. The presence of Negri bodies was in most cases in discreet, and the fragments with higher concentrations of antigen by both techniques employed were the cerebellum and the brain stem. Immunohistochemistry test (IHC) demonstrated greater sensitivity when applied to samples of bovines. Our results showed that in 37.5% of the total number of fragments analyzed, viral inclusions were not observed, however, there was an inflammatory process. In relation to the species, the fragments from bovine’s animals showed a slight increase when examined under this feature. These findings highlight the importance of submitting samples from suspected animals for laboratory diagnostic, even when there are no apparent abnormal histological findings.
