La siguiente pandemia 🦠🤒
La mayoría de las enfermedades infecciosas nuevas surgen por el contacto entre animales y humanos
Es importante conocer la cantidad de patógenos transmitidos por esta vía, especialmente #virus y así poder limitar el contacto con ellos

El probable origen del #SARSCoV2 en un mercado de animales ha puesto al descubierto una vez más, el papel que juega el comercio de #VidaSilvestre sobre posibles zoonosis, es decir, enfermedades transmitidas de animales al ser humano 🦆➡️👵🏻

The African crested rat looks adorable, but its fur is packed with lethal poison—just milligrams can kill a human. New study discovered they also have a rich social life.@NationalZoo @museumsofkenya @UUtah @MDeniseDearing @SaraBWeinstein doi.org/10.1093/jmamma… 📷StephanieHiggins
People in East Africa have known the rat to be poisonous but its source was mysterious. A 2011 paper proposed these rabbit-sized rodents sequester toxins from the poison arrow tree Acokanthera schimperi. They’re the only #mammals to use plant toxins for defense.
The 2011 study hypothesized that the rats chew Acokanthera bark and lick the plant toxins into specialized hairs at the center of these stripes. In the photo, the larger, porous center hair is poisonous, compared to the normal ones in the background. PC: @SaraBWeinstein @UUtah
Are #Bats and #Rodents special reservoirs? New study found that "Animal orders of established importance as zoonotic reservoirs including bats and rodents were UNEXCEPTIONAL, maintaining numbers of zoonoses that closely matched expectations for mammalian groups of their size. 1/n
More host species = more viral species all together. As simple as that!
"[...] reservoir species richness was correlated with both the number of zoonotic viruses (65.5% of deviance) and the viral richness (56.4% of deviance) of different reservoir orders" 2/n
"[...] reservoir species richness was correlated with both the number of zoonotic viruses (65.5% of deviance) and the viral richness (56.4% of deviance) of different reservoir orders" 2/n
"variation in the number of zoonoses maintained by each reservoir group was consistent with a largely host-neutral model, whereby more species-rich reservoir groups host more virus species and therefore a larger number of zoonotic species". 3/n
