[Detection frequency of haemoplasma infections of the domestic cat in Germany].

We present epidemiological data on the frequency of infections with haemotrophic Mycoplasma spp. (feline haemoplasmas) in domestic cats in Germany. From November 2004 to October 2006 135 blood samples of anaemic patients and cats without clinical symptoms were examined with conventional and real-time PCR methods. In 15,6 % of the samples DNA of one or more haemoplasma species could be detected. 8,9 % of the samples (12 cats) were infected with "Candidatus Mycoplasma haemominutum, whereas 7,4 % (10 cats) were infected with Mycoplasma haemofelis. Out of these, one cat harboured both species. The recently described species "Candidatus Mycoplasma turicensis" was found in 2.2 % of all samples (3 cats) and was restricted to animals coinfected with M. haemofelis. No correlation could be detected between the infection with haemotrophic Mycoplasma spp. and clinical signs of anaemia or disease. Infections were significantly correlated with age, male gender or coinfections with retroviruses (FIV, FeLV). Our data indicate, that chronically infected carriers without clinical symptoms are frequent in the investigated cat populations in Germany and that the screening of blood-donors for the presence of Mycoplasma spp. infections is advisable before clinical use.
