English: BLACK SPOT  -  Dutch: ZWARTE STIP - German: SCHWARZER PUNKT The Black Spot is a common disease in canaries, finches also in other kind of birds. During the last few years this infection has progressed. Can this disease be stopped? Many breeders lost their nestlings during the first days of life. In most cases the cause is unknown and many breeders make the females responsible for poor feeding.
How does the disease apparent? Adult birds with a good immune system show no symptoms. This is also dependent of the attitude conditions. In birds the mycoplasma live mainly in the respiratory organs, the ovary and the fallopian tube without symptoms of a disease. If in adult birds it should come to the outbreak of the disease the following signs are to be determined: -    decrease of the vitality. - decrease of the putting achievement of the females. - heavy breathing with opened bill and a strong pumping the whole body. - the swollen mucous membranes in the bronchi cause rattling noises with breathing. - Swelling at the head arise (owl head). - Vomiting and coughing can be observed. In larger kinds of bird such as parakeets and parrots it comes to frequent sneezing with strong, slimy nose discharge.
If the birds are infected with the mycoplasma, secondary diseases are always possible, such as e-coli, coccidiosis  or other infections. Note: However a scientific proof is not present. An mycoplasma infection of the nestlings take place already in the ovary. The black spot is to be seen direct or 1-2 days after hatch out of the egg. The black spot can be observed on the right side of the abdomen. The size of the black spot varies. Eventually only some nestlings survive, if they reached 6-8 days after hatch out. The chance of survival also depends of a very good supply by the female.

Treatment and prevention against the Black Spot The treatments against mycoplasma are not straight successful. Vets often recommend the administration of Tylosin. Often in small kind of birds, such as canaries or gouldian finches, the treatments with tylosin remain visible, as far as these are not yet fully grown. Many breeders have reported that after the treatment with Tylosin the symptoms of the disease came back. As with all infections, cleanliness is one of the first precondition for a good protection. Daily change the water, the food and also clean the food bowls are recommended.

What caused the Black Spot? The Black Spot is caused by mycoplasma. Mycoplasma are the smallest organisms. Mycoplasma stand in the micro-biological classification between bacteria and viruses. Mycoplasma are many smaller contrary to bacteria and viruses than these. Their diameter amounts to 0,2-2,0µm. They survive even lowest temperatures.
