Prolapso peniano em tartaruga-verde (Chelonia mydas) / Penile prolapse in green sea turtle (Chelonia mydas)

A ocorrência de prolapso peniano em repteis é observada tanto em quelônios terrestres, quanto em squamatas, porém há a escassez de relatos em tartarugas marinhas documentados até o momento. Desta forma, objetivou-se relatar o processo de reabilitação de uma tartaruga-verde (Chelonia mydas) com prolapso peniano, de modo a nortear procedimentos clínicos e terapêuticos que possam propiciar maior sucesso na reabilitação destes animais. Uma tartaruga-verde (C. mydas), adulto, macho, foi resgatada no dia 02 de maio de 2020 na praia de Muriú, Ceará Mirim, Rio Grande do Norte, Brasil. O espécime encontrava-se ativo, responsivo, com bom escore corpóreo, hidratação moderada, presença de prolapso peniano com mucosa associada hiperêmica e parte necrosada, além disso, encontrava-se com a nadadeira anterior esquerda amputada. O animal recebeu suporte terapêutico à base de analgésicos, antibióticos, anti-inflamatórios, polivitamínicos e fluidoterapia. Foram realizados procedimentos cirúrgicos para remoção total do úmero e redução mecânica do prolapso peniano. Após 50 dias de reabilitação o animal teve alta médica e foi reintroduzido de volta ao mar. Conclui-se que o protocolo utilizado, tanto na reabilitação, quanto no tratamento conservativo do prolapso peniano mostrou-se eficaz na redução do edema, evitando assim a recidiva do prolapso.(AU)

The occurrence of penile prolapse in reptiles has been observed both in terrestrial turtles and squamates. However, there are few reports of penile prolapse in sea turtles published to date. This study aimed at reporting the rehabilitation process of a green sea turtle (Chelonia mydas) with penile prolapse, in order to guide clinical and therapeutic measures that can provide greater success in the rehabilitation of these animals. An adult male green sea turtle (C. mydas) was rescued on May 2, 2020 at Muriú beach, Ceará Mirim, Rio Grande do Norte, Brazil. The specimen was active and responsive, with a good body score and moderate hydration, and showed the presence of penile prolapse with associated hyperemic mucosa and necrosis. It also had the left anterior fin amputated. The animal received therapeutic support based on antibiotics, analgesics, anti-inflammatories, multivitamins, and fluid therapy. The surgical procedure for the complete removal of the humerus and mechanical reduction of penile prolapse was performed. After 50 days of rehabilitation, the animal was discharged and was reintroduced back to the sea. It is concluded that the protocol used was effective in reducing edema, thus preventing the recurrence of prolapse, both in rehabilitation and in the conservative treatment of penile prolapse(AU)

Doenças infecciosas e não infecciosas nos peixes-boi do Brasil / Infectious and non-infectious diseases in manatees in Brazil

Background: Antillean manatee (Trichechus manatus) and Amazonian manatee (Trichechus inunguis) are the two species of manatees that occur in Brazil, and both are endangered. Studies on manatee disease in Brazil were previously based mainly on Florida manatees. In recent years, these studies have increased in Brazil. Thus, the objective was to carry out a survey of the publications of infectious and non-infectious diseases in the two species of manatees that occur in the country, to assist in the identification of threats to the species and in the health assessment of manatees in the country. Review: Regarding infectious and contagious diseases, parasites have affected both species of manatees in Brazil, such as Pulmonicola cochleotrema in wild T. manatus, Toxoplasma gondii in both species, and Cryptosporidium spp. also in both species, this being an important agent of zoonotic character. Giardia sp., another zoonotic parasite, has also been reported in both species of manatees in Brazil. Mycotic lesions caused by B. hawaiiensis have been described in calves of T. manatus in captivity. Meanwhile, Candida sp., Trichosporon sp., Rhodotorula sp., and Cryptococcus sp. have been identified in T. inunguis. Studies on viruses in manatees are still not widespread compared to other species; however, it has been verified that rotavirus is present in T. manatus in captivity. In studies carried out to identify bacteria in T. manatus, the following bacteria were isolated: Arizona sp., Bacillus sp., Corynebacterium equi, Corynebacterium pseudodiphteriticum, Corinebacterium sp., Edwasiella tarda, Enterobacter aerogenes, Enterobacter agglomerans, Enterobacter sakasakii, Escherichia coli, Leptospira spp., Proteus sp., Proteus vulgaris, Providencia rettgeri...

Piotórax em peixe-boi-marinho (Trichechus manatus) no Brasil / Pyothorax in Antillean manatee (Trichechus manatus) in Brazil

Background: Manatees are the most endangered aquatic mammals in Brazil. The current conservation scenario, together with their biological characteristics, raises concern with the future of this species. Pyothorax, also known as septic pleural effusion or pleural empyema, is characterized by the accumulation of a septic purulent exudate within the pleural space. Although this infection often has a multifactorial etiology, it is most commonly associated with respiratory tract disorders and trauma. Here, we report a case of pyothorax in a Antillean manatee (Trichechus manatus) held in captivity for acclimatization in Brazil. Case: A young, male Antillean manatee, aged 4 years and 11 months, measuring 227 cm in total length, and weighing 258 kg was held in captivity for acclimatization (natural environment) in Porto de Pedras in the State of Alagoas, Brazil. The animal died in February 2013 and was sent for necropsy at the CMA/ICMBio laboratory. The study was developed with authorisation from the Ethics Committee on Animal Use (License number 020/2009) and under the license SISBIO/ ICMBio number 20685-1. Externally, the carcass of the animal showed swelling and bulging of the right antimere and purulent secretion from the right nostril. After external examination, a window was opened in the layers of skin, fat, and muscles from the level of the anus to the navel. Subsequently, the abdominal cavity was opened for inspecting the internal organs. The subcutaneous muscles had a slightly friable, swollen, and pale texture, in addition to petechial hemorrhage, suffusions, and marked edema of the subcutaneous tissue. The right hemidiaphragm was elevated, filling the abdominal and thoracic spaces. Depending on the elevation, all organs were moved to...
