[edit] Cultivation

In Microbiologcal laboratories, B. anserina bacteriae can be grown on special protein enriched mediums (rich in ovoalbumins or animal tissue (that countains Myoglobin)), in anaerobic conditions. They can also be grown in embrionated chicken eggs. The laboratory cultivation of B. anserina is rarely done and constitutes a diagnosys method in bird boreliosis and spirochetosis.^[1]

[edit] Pathogenity

B. anserina is a pathogenic agent for birds (chickens, turkeys, ducks etc.) and causes a disease called boreliosis or spirochetosis. This bacteria is transmited from bird to bird by ticks from the Argas and Ornitodorus genus. The major symptoms of an infection with B. anserina are: anemia, diarrhea and severe neurological disfunctions.

These two ticks represent the Argasidae “soft ticks” (Lt), and the Ixodidae “hard ticks”
