Apparently, it is present in the normal soil flora in low numbers, but under ideal conditions, in soil rich in nitrogen and organic matter, with pH above 6 and a temperature higher than Anthrax is endemic all over the world, but the possibility of the bacteria to grow and multiply as saprophytes in the environment has not been established definitively. Five outbreaks occurred between January and March, three outbreaks between May and July, and two outbreaks in October-November.
In the other outbreaks the animals were found dead, suggesting that the disease was peracute.

The disease occurs in all South American countries and Mexico. The number of anthrax outbreaks from to represents 0. Probably in this outbreak the animals were incubating the disease at the time of vaccination.
Later, anthrax was diagnosed in cattle found dead without the observation of clinical signs. Despite the large population of sheep in the region, anthrax was not diagnosed in this species during the period, and only one farmer mentioned the death of some of them.

Cattle found dead had dark tarry blood, which did not clot, from the natural orifices, and assumed the typical “sawhorse” posture. On this farm, the owner also mentioned that the disease occurred more than 30 years ago, and after many years of vaccination this practice was anrax.

Blood was obtained from an amputated ear or metatarsal bone, or collected with a syringe from subcutaneous exudates, jugular vein, or bovinks discharges from the natural orifices.
In Argentina, between andfrom samples with suspicion of anthrax, 25 were positive. Accessed on 30th April All diagnoses were made on specimens sent by veterinarians or collected by the author s in visits to the affected farms.
Diagnosis can be reliably made with the polychromatic methylene blue staining of blood or exudates smears. Clinically the peracute form was more frequent, but in some outbreaks the acute form with a clinical manifestation period of hours was also observed. In Outbreak 6 cattle had been transported recently from another farm.
The source of infection was not established; but the reduced rainfall, associated with boinos, flat, flooded lands used for agriculture followed by animal grazing after harvest was probably related to the disease occurrence. Outbreaks 1, 4, 5, 6 and 9 affected years old cattle, but in two of those outbreaks 1 and 5animals 4 years old or older were also affected.
Those outbreaks started in and were markedly seasonal; 18 of them occurred from January to March Rojas et al. Priebe IV ; Milton Bovinoos. Outbreaks of anthrax are frequent in tropical and subtropical countries with high annual rainfalls.

In Outbreak 4 cattle were introduced to the farm 9 months before the outbreak, from the municipality of Dom Pedrito. Blood smears showed large Gram-positive rods, isolated or in chains, similar to B. Periodical plowing and frequent floods could be responsible for the presence of spores in areas where the disease occurred before.
