AnthraxAnthrax in pigs is relatively rare and it may occur as sudden death. It can also take other forms of presentation, depending on the location of the infection: pharynx anthrax, intestinal anthrax or systemic anthrax. It is very critical to carry out a necropsy in the field because the environment can get contaminated with the spores. Anthrax is a zoonotic disease.

E-diagnostics is a tool used to diagnose disease in swine, developed by 333 in collaboration with DVM Alex Ramírez, Associated Professor at Arizona State University.
This tool should only be used as an illustrative guide, under the responsibility of the user.
How the tool works
Select the age of the animals and then the symptoms observed, starting with the most relevant ones. As symptoms are marked, the list of possible diseases that can cause them will be shown for each age group. As more symptoms are selected, the list of possible diseases will be reduced to those that match all the selected symptoms. At the same time, the symptoms that do not correspond to the resulting diseases are deactivated.
The number that appears next to each symptom corresponds to the number of diseases that can cause the associated symptom.
Results
Marking a symptom will display the number of possible causative diseases. Clicking on this number will bring up a complete list of diseases sorted by age group and likelihood of occurrence- with those listed in a more intense color being the most likely. The resulting number of diseases will be updated as new symptoms are marked. Clicking on the name of each disease we will access a detailed description of the disease with images of the most common lesions.
E-diagnostics is a tool that should be used only as a guide and under the responsibility of the user. Keep in mind that disease presentation and severity will depend considerably on the situation in which they occur. Another thing to consider is that we tend to think about diseases as individual entities when in reality several concurrent problems are often found.
