infectious disease serologic survey in free-ranging venezuelan anacondas (eunectes murinus).reptiles can harbor pathogenic microorganisms asymptomatically and serve as potential reservoirs of infection for humans, domestic animals, and other reptiles. infectious diseases are also problematic for free-ranging reptile populations and are an important consideration in reptile reintroduction and translocation projects. there have been limited serologic studies of free-ranging reptiles for evidence of exposure to potential pathogens. in the present study, serum or plasma samples from five m ...200112785679
cutaneous and pulmonary mycosis in green anacondas (euncectes murinus).two dead, captive green anacondas (eunectes murinus), including one male and one female, submitted for necropsy were in poor body condition, having multiple, scattered, dark red foci on the scales and mottled lungs. both snakes had severe mycotic dermatitis. in addition, the male snake had mycotic stomatitis, and the female snake had mycotic pneumonia. trichophyton sp., verticillium sp., and alternaria sp. were isolated from the dermal lesions. the pulmonary lesions were morphologically consiste ...200415732602
dracunculus brasiliensis sp. n. (nematoda: dracunculidae) from the anaconda, eunectes murinus (ophidia: boidae).dracunculus brasiliensis sp. n. (dracunculidae), is described based on a single female specimen found in the body cavity of the anaconda, eunectes murinus (l.) (ophidia: boidae), from the mexiana island, amazon river delta, brazil and one female previously recorded from the subcutaneous tissue of this host species imported from south america into europe (zoo in the czech republic). the new species is characterised mainly by markedly large, anteriorly protruding dorsal and ventral double papillae ...200918975002

snake mating systems, behavior, and evolution: the revisionary implications of recent findings.sexual selection and mating systems profoundly influence the behavior and psychology of animals. using their own studies of green anacondas (eunectes murinus) and reviewing other recent studies, the authors conclude that incomplete data derived from a few well-studied snake species have led to general acceptance of polygyny as the dominant mating system in snakes. new data on behavior, paternity, and life history in a diverse taxonomic array of snakes support the view that polyandry is not only ...200516366778
fatal systemic necrotizing infections associated with a novel paramyxovirus, anaconda paramyxovirus, in green anaconda juveniles.beginning in july 2011, 31 green anaconda (eunectes murinus) juveniles from an oceanarium in hong kong died over a 12-month period. necropsy revealed at least two of the following features in 23 necropsies: dermatitis, severe pan-nephritis, and/or severe systemic multiorgan necrotizing inflammation. histopathological examination revealed severe necrotizing inflammation in various organs, most prominently the kidneys. electron microscopic examination of primary tissues revealed intralesional accu ...201425078906
anaconda paramyxovirus infection in an adult green anaconda after prolonged incubation: pathological characterization and whole genome sequence analysis.from july 2011 to june 2012, 31 out of 33 green anaconda juveniles from an oceanarium in hong kong died over a 12-month period. these anacondas were progeny of a female anaconda purchased from japan and added to the collection in may 2011. the juvenile anacondas were born in july 2011. a novel paramyxovirus, named anaconda paramyxovirus (anapv), was isolated from these affected juvenile anacondas. in july 2015, one of the remaining two anacondas, that survived the cluster of fatal infections, di ...201728404483
facultative parthenogenesis validated by dna analyses in the green anaconda (eunectes murinus).in reptiles, the mode of reproduction is typically sexual. however, facultative parthenogenesis occurs in some squamata, such as komodo dragon (varanus komodoensis) and burmese python (python bivittatus). here, we report facultative parthenogenesis in the green anaconda (eunectes murinus). we found two fully developed female neonates and 17 undeveloped eggs in the oviduct of a female anaconda isolated from other individuals for eight years and two months at ueno zoo, japan. to clarify the zygosi ...201729236745

activity of tabanids (insecta: diptera: tabanidae) attacking the reptiles caiman crocodilus (linn.) (alligatoridae) and eunectes murinus (linn.) (boidae), in the central amazon, brazil.tabanid females are better known as hematophagous on man and other mammals, and linked to mechanical transmission of parasites. the association between tabanids and reptiles is poorly known, but has been gaining more corroboration through experiments and occasional observation in the tropics. the present study was conducted at a military base (cigs/bi-2), situated 54 km from manaus, amazonas, in a small stream in a clearing (02 degrees 45'33"s; 59 degrees 51'03"w). observations were made monthly ...200211992164

environmental dna (edna) sampling improves occurrence and detection estimates of invasive burmese pythons.environmental dna (edna) methods are used to detect dna that is shed into the aquatic environment by cryptic or low density species. applied in edna studies, occupancy models can be used to estimate occurrence and detection probabilities and thereby account for imperfect detection. however, occupancy terminology has been applied inconsistently in edna studies, and many have calculated occurrence probabilities while not considering the effects of imperfect detection. low detection of invasive gia ...201525874630
is the karyotype of neotropical boid snakes really conserved? cytotaxonomy, chromosomal rearrangements and karyotype organization in the boidae family.boids are primitive snakes from a basal lineage that is widely distributed in neotropical region. many of these species are both morphologically and biogeographically divergent, and the relationship among some species remains uncertain even with evolutionary and phylogenetic studies being proposed for the group. for a better understanding of the evolutionary relationship between these snakes, we cytogenetically analysed 7 species and 3 subspecies of neotropical snakes from the boidae family usin ...201627494409
