Ed · Answer

A brucelose é uma doença infecciosa causada por bactérias do gênero Brucella. Os principais mecanismos de transmissão da brucelose são:

I - A principal fonte de infecção são fêmeas grávidas, que eliminam grandes quantidades do agente durante o aborto ou parto e durante o período puerperal.
II - Qualquer hospedeiro vertebrado portador saudável ou doente que abriga a Brucella e a elimina no ambiente é uma importante fonte de infecção.
III - A transmissão através do coito não é de grande importância entre bovinos e búfalos.
IV - A transmissão através do sistema respiratório é rara.

Portanto, a alternativa correta é a letra "c) Apenas I, II e IV estão corretas".
