Haemoplasmosis, formerly called haemobartonellosis, is a vector-suspected infection of the red blood cells that affects both, cats (Clark, 1942; Flint and Moss, 1953; Foley et al., 1998; Willi et al., 2005) and dogs (Benjamin and Lumb, 1959; Donovan and Loeb, 1960). Besides these two affected species, closely related haemoplasmas have also been detected in several other mammals (see e.g., Messick, 2004 for detailed listing), and a zoonotic potential of haemoplasmas can also not be excluded and should be further addressed (Sykes, 2010; Willi et al., 2007).

The mode of transmission of feline and canine haemoplasmas is still under discussion. Arthropods, here especially fleas and ticks, have been suggested as vectors. Thus, listing of the disease could be under tick-borne diseases, but also under flea-borne diseases. Under the latter you will find detailed information on our website. Please see under haemoplasmossis for further data.
