“…A study developed in Brazil with 14 females vaccinated between 3 and 8 months old with B19 vaccine strain showed persistent excretion of the strain until 9 years of age. The most common route was through urine, and the excretion period was mostly from when they were on heat to 150 days gestation and until 30 days after birth (Pacheco, ). These results could help to explain the large number of animals infected with B. abortus B19 DNA, knowing they were all breeders and had an intimate contact with females on heat.…”

“…Outra alternativa seria a vacinação inadvertida de machos junto com fêmeas bovinas entre 3 e 8 meses de idade, que resultaria em infecção persistente na vesícula seminal e próstata, com eliminação da bactéria pelo sêmen (Figura 9). Embora o mecanismo de infecção por B. abortus cepa vacinal B19 seja semelhante ao da cepa de campo, não está totalmente esclarecido quais substancias favorecem a multiplicação no organismo hospedeiro (PACHECO, 2007).…”

“…Essas fêmeas servem como manequins e na maioria das vezes urinam quando estão juntas com os machos. Foi demonstrado no trabalho de Pacheco (2007) que fêmeas adultas vacinadas na idade correta podem eliminar a cepa vacinal B19 na urina. Dessa forma, esses animais possam ser uma possível fonte de infecção.…”
