A compactação de fezes endurecidas no interior do trato intestinal é denominada de fecaloma, a qual está atrelada a fatores que interfiram na excreção normal do bolo fecal. O diagnóstico deve ser realizado de forma rápida, unindo o histórico do paciente, exame clínico, laboratoriais e  de imagem, a fim de se atenuar os efeitos deletérios da dilatação exagerada do lúmen intestinal e alteração em seu fluxo, por meio da escolha da terapêutica mais adequada em cada caso, que pode ser conservativa ou cirúrgica. O presente manuscrito tem como objetivo relatar um caso de fecaloma gigante em um paciente canino.

Resistance profile of bacterial isolates from different llama microbiotas (Lama glama Linnaeus 1758)[Perfil de resistência de isolados bacterianos de diferentes microbiotas de lhamas (Lama glama Linnaeus 1758)]

Background: Studies on intestinal parasites in cougars Puma concolor are scarce, and most of the available information on the species has been derived from individuals in captivity. One of the greatest threats to the survival of wild cats is habitat loss caused by urban sprawl, agricultural matrix, and linear developments such as highways and railways, which expose animals to direct contact with humans and to a high risk of death. Given the lack of scientific data the objective of this study was to report on the occurrence of intestinal parasites in a cougar (P. concolor) specimen from the northwestern region of Paraná State, Brazil.Case: The carcass of a free-living cougar (P. concolor) individual was sent to the Interdisciplinary Science Museum (Museu Interdisciplinar de Ciências – MIC) of Paranaense University (Universidade Paranaense - UNIPAR); an individual was killed during a collision with an unidentified vehicle on highway PR-486, in the municipality of Mariluz (PR, Brazil). The geographical coordinates of the location where the animal was found are: 23°59′29″S, 53°8′47″W. This region is characterized by semi-deciduous seasonal forest remnants. After being identified on site and collected by the inspectors of the Paraná Environmental Institute (Instituto Ambiental do Paraná - IAP), the cadaver was donated to the MIC (by the IAP) for a necropsy to elucidate the cause of death. In this context, the cadaver was sent to the Animal Pathology section of the Department of Veterinary Medicine at UNIPAR. The animal was necropsied by performing the standard necropsy technique for carnivores: opening the intestine through the mesentery and exposing the mucosa from the duodenum to the colon. The necropsy showed that the cause of death was hypovolemic shock due to trauma. During necropsy, parasites in the intestinal lumen were visible to the naked eye. Parasites and feces were collected and stored in sterile flasks containing 10% formaldehyde and saline. The parasites were subjected to Faust and Hoffman techniques, micrometry, and morphological analysis, resulting in the identification of the roundworm Toxocara cati and the tapeworm Spirometra decipiens.Discussion: Identifying the roadkill species along highways is of paramount importance, since they are living very close to man and, consequently, reservoirs and disseminators of different infectious and parasitic zoonoses may be possible. Infection by protozoa and helminths in animals usually occurs by ingesting the infective form present in food or water. Toxocara cati and the tapeworm Spirometra decipiens were only reported in captivity before. Research on parasites in free-living wild animals is not common in the scientific literature and this is due to the difficulty of capturing this animal category as they live in difficult to access places such as forests and forests, therefore, research projects in partnership with museums are extremely important for the recognition of wild animal species that circulate in the region, in addition to the parasitic identification of these animals for future sanitary measures and for the preservation of the animal species in the environment. The Parasitological studies of wild animals are highly relevant for expanding this knowledge, especially considering the possible transfer risk of specific parasitic diseases to other animals, as well as to humans.

Periodontal disease is one of the most common and prevalent oral diseases in dogs. With the increasing closeness between man and the animals of company, the care with the health and well-being of those animals also increase. Being the bacterial plaque the main cause of periodontal disease, oral care performed by dog owners are essential for the prevention and control of this disease. There are a lot of alternatives, developed exclusively for animal use, which assist in oral hygiene. There are data on the use of active natural products in the prevention of halitosis, dental plaque and calculus, in the form of antiseptic substances, but the volume of information is still scarce. Natural substances, used since immemorial times for treatment of diseases, have the potential to integrate oral care products, such as main or adjuvant active agent in the formulation of the most varied compounds. This is the result of desirable actions in oral and dental therapies, as anti-inflammatory, healing and antimicrobial. This article reviews the information available on the subject and seeks to indicate what is possible to do overcome the gap between research and application of these products on a day-to-day basis.

Background: The indiscriminate use of antibiotics both in humans and in animals, has contributed to the development of bacterial resistance. One of the key mechanisms in the resistance of enterobacteria to antibiotics is the production of extendedspectrum β-lactamases (ESBLs), which reduce the therapeutic options available. Several studies have been performed in different animal species in order to isolate and identify multidrug-resistant strains and determine their antibiotic sensitivity profile. The purpose of this study was to detect ESBL-producing enterobacteria in isolates from a pet blue-fronted amazon parrot.Case: A 16-year-old pet blue-fronted-amazon parrot (Amazona aestiva) weighing 0.445 kg, from the city of Presidente Castelo Branco, Paraná, Brazil, was admitted into a specialized veterinary clinic in the city of Maringá. This parrot was presented with agitation and aggressive behavior. It was fed with sunflower seeds, and its cage was small and unsanitary especially in the feeding and drinking areas, which were heavily contaminated with feces. The parrot had been diagnosed with acute sinusitis approximately one year prior, with a history of treatment with tylosin, thuya (a herbal remedy popularly used for fowl pox), and a mineral-vitamin complex. The clinical symptoms included dyspnea and bilateral increase of facial swelling, with a mass in the peri-nasal region. A membranous red tissue not related to the nictitating membrane was observed in the lower left eyelid. To obtain a better clinical evaluation, the bird was anesthetized with an intramuscular injection of dextroketamine 50 mg/kg (KetaminS+™). Subsequently, physical examination, head radiographic examinations, and an attempt at sinus draining were performed. The radiographic examinations showed a decreased amount of air in the nasal sinuses. For treatment, oral itraconazole and vitamin A were prescribed, and a dietary improvement, prioritizing the offering of fruits and industrialized food for parrots was proposed. Samples were collected from the cloaca and choanae by making rotating movements with compressed sterile swabs in the corresponding locations. All samples were kept in Amies transport media with activated coal and forwarded under refrigeration to the Laboratory of Preventive Veterinary Medicine and Public Health in the Post-Graduation Program in Animal Sciences with Emphasis in Bioactive Products at Universidade Paranaense (UNIPAR).Discussion: The samples were subjected to phenotypic antimicrobial sensitivity tests and phenotypic testing for detecting ESBL-producing strains. Escherichia coli was identified and isolated from the cloacal sample. Phenotypic tests for antimicrobial sensitivity, detected resistance to the following antimicrobials: ceftriaxone, ceftiofur, cefotaxime, cefepime, ampicillin, amoxicillin, amoxicillin + clavulanate, and tetracycline. The phenotypic test for detecting ESBL-producing strains was positive. The findings in this study had no relation with the clinical symptoms presented by the parrot. However, in the samples collected, it was possible to detect the presence of ESBL-producing Escherichia coli, indicating that this parrot had strains in its cloacal microbiota that were either multidrug-resistant or at a subclinical stage of an infection. This knowledge is important, since the presence of this bacteria in a pet represents an important factor in the dissemination of multidrug-resistant strains into the environment, as well as being a source of contamination for both humans and other animals.
