Leishmaniasis is a zoonotic disease of worldwide relevance. Visceral leishmaniasis endemic in Brazil, where it caused by Leishmania infantum with Lutzomyia longipalpis being the most important invertebrate vector. Non-human primates are susceptible to L. infection. However, little known about role these species as reservoirs. The aim this study was evaluate transmissibility potential visceral non-human through xenodiagnosis using phlebotomine Lu. well identify prevalent area were kept...
Leishmania (Leishmania) infantum is the cause of visceral leishmaniasis in Americas. The disease transmitted mostly through bite invertebrate vector, phlebotomine Lutzomyia longipalpis New World. Although domestic dog considered most important reservoir disease, other mammalian, including wildlife, are susceptible to infection. goal this study was perform xenodiagnosis evaluate capacity naturally infected maned wolves (Chrysocyon brachyurus) and bush dogs (Speothos venaticus) transmit female...
Visceral leishmaniasis is a chronic infectious disease caused by Leishmania infantum (synonym: chagasi) and transmitted the sandfly Lutzomyia longipalpis in Brazil. It an endemic zoonosis several regions of country, including Belo Horizonte (State Minas Gerais). In urban areas, domestic dog susceptible considered most important animal reservoir. However, L. has been previously diagnosed other species, captive primates canids. This study aimed to evaluate presence agent DNA animals as well...
Some wild species of mammals and birds are prone to excessive iron accumulation, especially when maintained in human care. Hemosiderosis is the process intracellular accumulation without evidence toxicity, whereas hemochromatosis characterized by severe with accompanying organ damage. Iron storage disease (ISD) occurs damage causing clinical signs. This retrospective study investigated occurrence hemosiderosis ISD across a variety avian taxa, including captive free-ranging birds. Archived...
Abstract Background Enteric diseases are among the most common causes of morbidity and mortality in gorillas, it is often caused by bacteria. Methods A thirteen‐year‐old captive female western lowland gorilla ( Gorilla ) developed hemorrhagic diarrhea. Despite treatment, animal died 7 days after onset clinical signs. The was submitted to a thorough pathological microbiological evaluation. Results Pathologic examination revealed severe acute colitis, neutrophilic splenitis, glomerulitis,...
Abstract Streptococcus pasteurianus is associated with endocarditis and sepsis in humans. A puerperal emperor tamarin died, necropsy showed a bacterial sepsis. DNA sequencing from the paraffinized heart tissue was compatible S. pasteurianus. could be an important agent tamarins.
Abstract A 2‐year‐old captive gorilla ( Gorilla ) was diagnosed with visceral leishmaniasis in Brazil, and treated a single dose of liposomal amphotericin B, which resulted clinical cure. This is the first report gorillas, reported B treatment great apes.
ABSTRACT A captive 12-year-old female maned wolf (Chrysocyon brachyurus), previously diagnosed with visceral leishmaniasis, developed severe myiasis in the right ear, followed by prostration and death. firm solid nodule, measuring 1 x 3cm, was grossly observed pancreas. Histologically, there neoplastic proliferation pancreas pancreatic lymph node. Neoplastic cells had a neuroendocrine pattern, were positive for gastrin polypeptide immunohistochemistry. The also ulcerative gastritis. To best...
Um crocodilo macho adulto (Crocodylus niloticus) foi diagnosticado com infecção fúngica sustêmica. Histologicamente, havia extensas áreas de necrose no pulmão, que estavam associadas infiltrado inflamatório linfo-plasmo-histiocitário, numerosas células gigantes multinucleadas e miríade pseudo-hifas organismos leveduriformes intralesionais, dentro favéolas distendidas. Focos necróticos também foram observados na mucosa do trato digestório, traquéia, túnica íntima artérias, fígado coração,...
The draft genome sequences of two Salmonella enterica serotype Infantis isolates are reported here. One the strains was isolated from a western lowland gorilla (Gorilla gorilla) with colitis. second strain reptile that inhabited same premises. Whole-genome sequencing demonstrated these were not clonal.
ABSTRACT A captive 7-year-old male bush dog (Speothos venaticus) was diagnosed with lymphoma affecting the kidneys, adrenal glands, liver, and spleen. The animal developed renal failure euthanized due to poor prognosis. Grossly, both kidneys were enlarged multiple nodules. Histologically, neoplasm an infiltrative poorly demarcated round cell tumor. Two morphologically distinct populations observed, smaller cells a lymphocytic morphology, another population of larger pleomorphic cells. Most...
Abstract Chylothorax is the accumulation of lymph in thoracic cavity, and it has never been reported neotropical primates. An emperor tamarin died at necropsy chylothorax associated with pulmonary compressive atelectasis was diagnosed. Idiopathic can be a cause respiratory insufficiency death tamarins.
ABSTRACT Lead is a heavy metal and an important cause of acute or chronic toxicosis in humans, domestic, wild animals. This report aims to describe case lead poisoning jaguar (Panthera onca) kept under human care that was rescued from the environment. The animal poor condition 2004 at Belo Horizonte Zoological Garden (Minas Gerais, Brazil) until 2020, when it presented with anorexia, vomiting ataxia. Over past years had episodes anemia increased serum urea creatinine. Radiography...
Reported cases of neoplasia affecting hippopotamus are very scarce.This report describes a metastatic oral squamous cell carcinoma in captive 44-year-old male common (Hippopotamus amphibius) that developed progressive loss appetite, fibrinohemorrhagic discharge, and weight loss.Gross, cytological, histopathological findings were compatible with conclusive diagnosis an invasive metastasis the lung, adrenal, spleen.To best our knowledge this is first hippopotamus.
A male adult crocodile (Crocodylus niloticus) was diagnosed with systemic yeast infection. Histologically, there were extensive areas of necrosis in the lung, which associated a diffuse severe lympho-plasmo-histiocytic inflammatory infiltrate, numerous multinucleated giant cells, and myriads intralesional pseudo-hyphae like organisms within distended foveolae. Necrotic foci also observed mucosa digestive tract, trachea, tunica intima arteries, liver, heart, marked lympho-histiocytic large...
Cardiac disease is of importance in captive chimpanzee (Pan troglodytes) health. Here we report an eosinophilic and necrotizing myocarditis a 17-y-old with no previous history cardiac that progressed to death within 48 h. Toxic infectious causes were ruled out. The had eosinophilia at different occasions years. animal severe, diffuse, acute monophasic myocarditis, moderate lymphoplasmacytic infiltrate was rich eosinophils. Ante- postmortem investigations are compatible unusual clinical...
Cholangiocarcinomas are neoplasms originating from the biliary epithelium.This report describes gross, microscopic, and immunohistochemical findings in a case of cholangiocarcinoma an Australian goose (Cereopsis novaehollandiae).The animal had cachexia ascites.The liver gallbladder cystic masses that was diagnosed as cholangiocarcinoma.
Polyarteritis nodosa is an idiopathic necrotizing vasculitis that affects small to medium-sized arteries. We describe a case of polyarteritis in captive common wooly monkey (Lagothrix lagotricha) associated with transmural intestinal necrosis and secondary peritonitis. This condition must be considered for differential diagnosis segmental arteritis neotropical primates.
Abstract Two cases of hepatocellular carcinoma (HCC) in 2 female captive golden‐headed lion tamarins ( Leontopithecus chrysomelas ) are described. HCC was diagnosed both, with pulmonary metastasis one them. Neoplastic cells were positive for hepatocyte‐specific antigen HSA by immunohistochemistry, confirming the diagnosis.
