With Adeno-Coli, up to 70% of your pigeons may be infected, showing these symptoms. The disease is a combination of an Adeno virus, which opens the way for the suddenly aggressive E-Coli bacteria (facultative pathogenic). Circo virus is often involved (an immune depressant disease) causing the birds to suffer, finding it harder and longer to get over the virus. When first looking at the signs of severe Adeno-Coli, the illness can be similar with other infections such as hexamitiasis, PMV (paramyxo), streptococcus infections or even a combinations of these diseases, as sometimes you may find that your birds do not show all of the symptoms at the same time. Adeno-Coli is very contagious from April to August and must be treated correctly. If any pigeons are seen racing with this problem you should immediately stop them from racing, to help with preventing the spread of further infection and to help the birds fully recover from the illness.

This virus cannot be prevented 100%, but precautions can be taken to reduce the risk; the most important thing is your bird’s immune system. Keeping the immune system active it is key to help your pigeons fight off any infection the best they can. It is also very important to be vigilant of any symptoms, making sure that you never treat to early, as some birds can peck about, ingesting moss which can cause vomiting and diarrhoea for 24 – 48 hours.
