The last few years we see more and more problems with our young pigeons. Mostly we see a combination of an infection with the adenovirus and the E.coli bacteria. The adenovirus type I damages the intestinal cells whereby an environment with a lot of proteins provides the ideal circumstances for a strong growth of the E.coli bacteria. This E.coli, which overgrows the normal intestinal flora, can produce toxins which can reach the blood and cause an intoxication. The young pigeons become sick and sometimes they even die.
Recently we also see more and more combined infections of circovirus and adenovirus. Due to the circovirus young pigeons are also increasingly harmed by common infections. In addition we notice more frequently the combination of E.coli and streptococcus.
