To evaluate seroprevalence of B. henselae infection both in Sicilian children and healthy blood donors. Furthermore, circulation of Bartonella in the natural reservoir was also studied. Two hundred forty-three children, living in Sicily (Palermo), affected by various diseases, without clinical features suggesting B. henselae infection, together with 122 healthy blood donors were serologically investigated for IgG and IgM antibodies by indirect fluorescent antibody test (IFAT). One hundred twenty stray and 62 pet cats were also analyzed only for IgG. Among children 25.1% had IgG antibodies to B. henselae; 18.5% showed a titer 1:64, 2.4% 1:128, 2.4% 1:256, 0.8% 1:512, 0.4% 1:1024, and 0.4% 1:5120. Among healthy blood donors 11.4% had IgG class antibodies to B. henselae; 9.8% showed a titer 1:64 and 1.6% 1:128. All the human serum samples did not show positive results for B. henselae IgM class antibodies. Stray cats (68.3%) and pet cats (35.4%) also had IgG class antibodies to B. henselae. We demonstrated high frequency of serologic evidence of past B. henselae infection, in young Italian children, affected by various diseases, apparently free of any clinical features suggesting B. henselae infection. This observation is supported by high circulation of Bartonella in cats.

D002415	Cats	The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.
