As you can see from the above chart, P.B.F.D. was detected at virtually every event but one. Polyoma was also detected at all events but one. Chlamydia, being a bacteria may be harder to detect or as the chart shows, may be less of a problem than the viruses present. If we had been swabbing tables with birds, the likelihood of detecting the presence of Chlamydia may be much greater. P.B.F.D. appears to have found a home within lovebirds.
Lovebirds can develop all majors signs of the disease and survive.
The relationship between Lovebirds and P.B.F.D. is still not fully understood. Polyoma Virus perpetuates itself with each successive generation and may be extremely difficult, if not impossible, to eliminate from breeding colonies. Cockatiels appear to be the group of parrots most able to survive with endemic Chlamydial infections. Only recently has a reliable test for Chlamydia been available. Not only do these three groups of birds comprise the greatest reservoir of the three major diseases, they also comprise the greatest number of birds present at typical bird events.
