RESUMO
Background: Pseudomonas aeruginosa is a bacterium that belongs to the microbiota of snakes, but it may also be anopportunistic pathogen and contaminate humans through fecal contact, bites, and injuries. In snakes, this microorganismmay present high pathogenicity at certain conditions and have been associated with high morbidity and mortality. Reportsof infection of Boa constrictor by this pathogen are rare. Thus, this study aimed to describe the P. aeruginosa oral infection in a snake specimen (Boa constrictor amarali), approaching the isolation and identification of the infectious agentsinvolved, the antimicrobial sensitivity and resistance, and the therapeutic protocol adopted.Case: A free-living adult female specimen of Boa constrictor amarali (Amarals boa), with no described previous history was rescued in an urban area by the Environmental Police. Clinical evaluations showed structures of caseous aspectin the oral cavity, with hyperemia spots in the mucosa. Samples of these lesions were sent for mycological examination,and fungal forms were not found. Samples were collected for isolation and culture. The antimicrobial susceptibility of theisolated microorganisms was determined by the modified Kirby-Bauer disk diffusion method. P. aeruginosa was isolatedand showed susceptibility to amikacin, gentamicin, and polymyxin-B; intermediate susceptibility to azithromycin, and ciprofloxacin; and resistance to cephalexin, ceftiofur, chloramphenicol, and enrofloxacin. The treatment consisted of cleaningof the oral cavity, local infiltration of lidocaine for debridement of the caseous area that were later cauterized with iodine.Systemic antibiotic therapy was used, with intramuscular administration of amikacin (5 mg/kg) for the first dose and (2.5mg/kg) for the other doses with intervals of 72 h, and oral administration of metronidazole...(AU)

Background: Stomatitis is an infectious disease common in serpents and responsible for high mortality rates. It is characterized by the infection of the oral mucosa and neighboring tissues, related to the opportunistic character of bacteria presentin the normal microbiota, pathogenic in stressful situations. Few studies have described the profile of sensibility of theseagents in serpents of the Brazilian fauna. Therefore, this study has aimed at describing the isolation and identification ofthe infectious agents involved in the clinic stomatitis in a specimen of green anaconda (Eunectes murinus), and the profileof sensibility and resistance to antimicrobial agents.Case: The serpent has been rescued in an urban environment, without previous records and featured erosive injuries inits oral cavity, with the presence of secretion. In a clinical evaluation, it has been assessed that the specimen had erosiveinjuries in its oral cavity, with hyperemic points in its mucosa and serous secretion. Then the specimen went through acollection of the secretion from its oral cavity for microbiological analysis. Typical colonies of Enterococcus, Citrobacterand Enterobacter were identified by the colony morphology and their typical odor. The results of these tests were able toconfirm and identify the Citrobacter freundii, Enterobacter and Enterococcus species. The profile of sensibility to antimicrobials of the isolated microorganisms has been determined through the method of diffusion in the disk of Kirby-Bauer.There was not any sensitive antimicrobial for the three agents. For treatment, based on the antimicrobial profile presented,was used Ciprofloxacin® associated to daily washings with solution of chlorhexidine 0.12% for 10 days. Clinical cure wasobserved at the end of this treatment.Discussion: Despite the high frequency of this disease...(AU)

Background: Liver performs several important functions to the maintenance of physiological mechanisms. Some liver diseases may directly affect anatomical and physiological aspects of this organ, and may lead to a permanent liver injury. In snakes, the most common causes of liver disease are infections, however, approaches on non-infectious liver diseases are scarce. Therefore, the objective of this study was to describe macroscopically and microscopically liver alterations in a Boa constrictor amarali snake.Case: A adult male boa (Boa constrictor amarali) snake of 110 cm of length and weight of 3.270 kg from free-living conditions, and without previous history was rescued in an urban area and taken by the Environmental Police to the Laboratory for Teaching and Research in Wild Animals (LAPAS) of the Federal University of Uberlândias (UFU) Veterinary Hospital, in Uberlândia MG, Brazil. The animal died and a significant amount of adipose tissue was found throughout the extension of the coelomic cavity at necropsy, limiting the visualization of its internal organs. Fragments of altered organs were collected and packed in a universal collector containing a 10% buffered formalin solution. These samples were sent to the Animal Pathology Laboratory (LPA) of the UFU. Macroscopically, the stomach presented a reddish mucosa, and mucous contents. The liver was pale, with a yellowish color and a friable consistency. Microscopically, dilated hepatic sinusoids filled with red blood cells were observed; the hepatocytes were enlarged, and its cytoplasm were filled with vacuoles of varied sizes that did not stain (severe diffuse lipidosis). It was also found occurrence of multifocal areas with loss of tissue architecture, and hepatocytes in karyolysis, charactering necrosis; and a discrete amount of multifocal mononuclear inflammatory infiltrate (multifocal hepatitis).[...]

Background: Bacterial diseases are the main cause of the high mortality rates of snakes, especially those caused by gramnegative agents. However, studies on dermatopathy caused by these bacterial agents in snakes are scarce; and no reports have been found on Enterobacter aerogenes as causative agent of dermatopathy in snake species. Thus, the objective of this study was to describe the clinical signs, and lesion evolution of a dermatopathy in a male snake (Boa constrictor amarali) specimen of approximately seven years old; and to describe the isolation and identification of the Enterobacter aerogenes and Pseudomonas aeruginosa agents involved in the cause of this disease. Case: The Boa constrictor amarali evaluated presented blackened cutaneous lesions in the dorsal, snout-vent and tail regions; and well-defined subcutaneous nodules of 2.0-3.0 cm diameter, with soft consistency, reddish color, cutaneous flaccidity, and areas of scale ulceration in the dorsolateral region. The clinical evaluation of the animal showed dehydration signs and pale mucous membranes. The blackened lesions were subjected to mycological analysis - after procedure of deep scale scraping - which showed presence of septate hyphae. The nodule was punctured for microbiological and biochemical analysis. The sample was collected with a sterilized alginate cotton tip swab, and was stored in a plastic tube containing a semi-solid Stuart transport medium, for microbiological analysis. Then, this sample was incubated in a bacteriological oven at 37°C for 24 h. Typical colonies of Pseudomonas and Enterobacter grew on MacConkey agar medium; these bacteria were identified by the colony morphology and their typical odor. The colonies grown in MacConkey agar were also identified through biochemical tests in the mediums: Phenol red, Lysine, Phenylalanine, Citrate, Urea and SIM (Sulfide, Indole, Motility)...(AU)
