Periods of drought have been observed in the Brazilian Pantanal for several decades, typically occurring from May to November. These droughts impact conservation thousands species, including yacare caiman (Caiman yacare). This study aimed describe pathologic and parasitologic findings postmortem examinations free-ranging caimans provide insights regarding influence extreme on health this species. In total, 13 were necropsied, representing deaths during a period (October 2021, 12 individuals)...
CTX-M-type extended-spectrum β-lactamase (ESBL)-producing Escherichia coli clones have been increasingly reported worldwide. In this regard, although discussions of transmission routes these bacteria are in evidence, molecular data lacking to elucidate the epidemiological impacts ESBL producers wild animals. study, we screened 90 animals living a surrounding area São Paulo, largest metropolitan city South America, monitor presence multidrug-resistant (MDR) Gram-negative bacteria. Using...
We detected neutralizing antibodies, viral RNA, and sialic acid receptors for Alphainfluenzavirus influenzae in urban coatis (Nasua nasua) Brazil, suggesting exposure susceptibility. used hemagglutination inhibition, reverse transcription quantitative PCR, histochemistry detection. Increased epidemiologic wildlife surveillance would improve influenza A emergency event response.
Yellow fever (YF) is an acute infectious disease caused by the yellow virus which transmitted mosquitoes. Neotropical primates are susceptible to infection, often presented as epizootic outbreaks. The aim was evaluate and characterize immune response against YF in different species of neotropical from Belo Horizonte Zoo. Vaccine 17DD administered 24 primates, with a single subcutaneous dose. Clinical exams, RNAemia, detection IgG neutralizing antibodies YFV were performed. In addition,...
<title>Abstract</title> Systemic isoporosis (atoxoplasmosis) is a disease caused by apicomplexan parasites of the genus <italic>Isospora</italic>, with systemic distribution due to an extraintestinal part cycle. In this report we described gross and histological lesions isosporosis in 15 passeriform birds from three different species: <italic>Sporophila maximiliani</italic> (great-billed seed finch), <italic>Serinus canaria</italic> (island canary), <italic>Saltator similis</italic>...
The global spread of critical-priority antimicrobial-resistant Enterobacterales by food is a public health problem. Wild-caught seafood are broadly consumed worldwide, but exposure to land-based pollution can favor their contamination clinically relevant bacteria. As part the Grand Challenges Explorations: New Approaches Characterize Global Burden Antimicrobial Resistance Program, we performed genomic surveillance and cell culture-based virulence investigation WHO critical priority isolated...
Reptiles are the unique ectothermic amniotes, providing key link between anamniotes fish and amphibians, endothermic birds mammals; becoming an important group to study with aim of significant knowledge into evolutionary history vertebrate immunity. Classification systems for reptiles' leukocytes have been described by their appearance rather than function, being still inconsistent. With advent modern techniques establishment analytical protocols snakes' blood flow cytometry, we bring a...
Abstract Background Toxoplasmosis is a zoonotic disease that affects humans and warm‐blooded animals. This study describes an outbreak of toxoplasmosis in howler monkeys ( Alouatta sp.) survival capuchins Sapajus apella ), under the same environmental conditions. Methods Howler were submitted to post‐mortem examination. Tissue samples processed histopathology immunohistochemistry detect lesions tachyzoites Toxoplasma gondii . also frozen PCR genotyping T. Results Typical observed several...
Congenital malformations have been reported in all classes of vertebrates and may be a determinant life span survival. In reptiles, the incidence congenital can associated with genetic environmental causes, including pollution. The characterization pathological processes involved development bone snakes is rare literature, but great relevance field reptile conservation health. We describe lesions 50 newborn jararaca (Bothrops jararaca) 26 South American rattlesnakes (Crotalus durissus...
Plasma in several organisms has components that promote resistance to envenomation by inhibiting specific proteins from snake venoms, such as phospholipases A2 (PLA2s). The major hypothesis for inhibitor's presence would be the protection against self-envenomation venomous snakes, but occurrence of inhibitors non-venomous snakes and other animals opened new perspectives this molecule. Thus, study showed first time structural functional characterization PLA2 inhibitor Boa constrictor serum...
Background The reptilian immune system is represented by innate, humoral, and cell‐mediated mechanisms, involving different types of blood leukocytes. development optimized methods for the advanced study origin function leukocytes needed. Objectives purpose was to optimize leukocyte density gradient isolation protocols from snake peripheral samples, characterize recovered cells flow cytometry based on size internal complexity a qualitative semi‐quantitative assessment populations in one boa...
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...
Peripheral nerve sheath tumors are a heterogeneous group of neoplasms that comprise neurofibromas, schwannomas, neurilemmomas, and perineuromas. In animals, peripheral most commonly diagnosed in dogs cattle, followed by horses, goats, cats, but their occurrence is uncommon birds. An adult, free-living, male toco (common) toucan (Ramphastos toco) was admitted to the zoo animal clinic with weight loss, dehydration, presence soft nodule adhered medial portion left pectoral muscle. Clinical,...
Native and exotic avian species can act as reservoirs of pathogens, including bacteria viruses, with conservation public health implications. A retrospective study on the diagnosis frequency diseases in wild was conducted. The occurrence particular associated type captivity or bird’s origin. investigation included macroscopic microscopic descriptions molecular determination causative agent(s). Additional immunohistochemical (IHC) analysis, PCR, genetic sequencing were total 243 cases...
This study assesses parasitism and pathologic manifestations in free-ranging Crotalus durissus terrificus. A total of 96 rattlesnakes from the State Minas Gerais (southeast Brazil) were necropsied between September 2019 February 2020. Granulomatous gastritis affected 48% (46 96) snakes evaluated, which associated with ascaridid nematodes Ophidascaris sp. Hexametra Other found included Kalicephalus costatus inermis (Diaphanocephalidae; 7%, 7 intestines, Serpentirhabdias (Rhabdiasidae; 18%, 17...
