We updated the distribution of Amphisbaena mertensi to northeastern central Brazil based on the finding of a specimen in an urban area in the Cerrado. This species had already been recorded in south-central Brazil, Paraguay, and Argentina. Our new record is 300 km away from the nearest point, Araguari, in the north of the State of Minas Gerais, Brazil. We included a distribution map for the species in South America, and a list of the amphisbaenas species found in Distrito Federal and discuss the conservation of this group.
We report a case of envenomation by
Dendrobates tinctorius
in
the northwest of the Amazon Forest. The patients were two men, who presented
with numbness in the right arm and slight numbness in the lower lip,
respectively.
Dendrobates tinctorius
secretions contain
pumiliotoxin, one of several toxins found in the dendrobatidis skin, which
interferes with muscle contraction and causes locomotor difficulties. Although
Dendrobatidae is a family of anurans known for their venom, few studies describe
the symptoms of envenomation in humans.
We report a case of erucism provoked by the Automeris egeus Cramer caterpillar and update the distribution of caterpillar poisoning in Brazil, showing the regions with the highest incidence rates. We also correlated the incidence rate with anthropic impact rates in all Brazilian municipalities, taking as a reference the Human Footprint Index. The victim presented erucism, burning pain, itching, and local hyperthermia. The highest incidence rates were in southern Brazil. We suggest including A. egeus in the Brazilian list of animals with medical importance, and that Brazilian Ministry of Health indicates the genus of the animals involved in envenomation events on its platform.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
