A cattle breeding estancia [ranch] of 450 mixed breed head in the General Alvear partido [2nd level administrative division], suffered the sudden death of a cow on 16 Oct 2012, with extravasation of blood from her natural openings. The herd had been vaccinated for anthrax but the date for the last vaccination is not known.

The attending veterinarian submitted a metacarpal bone [the standard protocol in Argentina]. _Bacillus anthracis_ was cultured and found to be sensitive to penicillin, ampicillin, tetracycline, gentamycin, florfenicol, and ciprofloxacin; and resistant to trimethoprim/sulfamethoxazole. A general alert was issued.

The carcass and area around the carcass were soaked with 5 percent formaldehyde, and then covered with a thick plastic tarpaulin, weighted around its perimeter to stop foxes accessing the carcass, [standard 'tapado controlado' protocol] for incineration at a later date.

The General Alvear partido has had 4 anthrax outbreaks since 2006.

[In many ways the province of Buenos Aires is very like North Dakota... it has a chernozem steppe soil(black, rich in carbonates and humus), which is perfect for spore survival, and the constant problem is to get the ranchers/estancieros to routinely vaccinate their stock each spring, which is now in Argentina. The good news is that the incidence these days is a fraction of what it was. Our thanks to Ramon for this report. - Mod.MHJ]
