ANTHRAX, BOVINE - ARGENTINA (BUENOS AIRES)

***********************************************







outbreak took place in bovines (bulls) when a herd of 300 were 

grazing on corn stubble. This outbreak occurred during a drought (180 

days with no rain). Approximately 15 days ago, it rained about 150 

vaccinated for almost 290 days. All the animals died suddenly, losing 

blood from their nostrils and anus. The animals were skinned (there 

are 3 people involved), and the veterinarians that made the 

necropsies saw splenomegaly, hemorrhagic enteritis and mesenteric 

adenitis. This farm had another outbreak 5 years ago. It is located 

in the Partido de Olavarria province of Buenos Aires, in the area 

known as Blanca Grande."

[Thanks to Ramon for this report. Anthrax is an ongoing problem in 

Buenos Aires Province, and more so than in any other province in 

spite of an active program to control it. But the incidence is 

dropping slowly. It should be noted that this outbreak occurred after 

softens the soil and encourages a rapid growth of forage, with the 

result that the hungry cows graze hard on this new growth and ingest 

soil, in this case contaminated. Thanks to the prolonged dry weather, 

their innate resistance will be down, and, therefore, the necessary 

infective dose of spores is reduced. Et voila! - Mod.MHJ]
