3.2. Cross-Reactivity. Studies have repeatedly demonstrated that cross-reactivity between B. henselae and B. quintana is very high, i.e., up to 95% presumably due to close phylogenetic relatedness [11, 70, 71].Considering that B. henselae and B. quintana can both cause lymphadenitis, infectious endocarditis, and bacillary angiomatosis [], high …

The main concern with cat scratches is transmission of a bacterium called Bartonella henselae, which causes cat-scratch disease (CSD), or cat-scratch fever, and is carried in the saliva of infected cats. About 40% of cats carry the B. henselae bacterium at some point in their lives, and most cats show no signs of illness. CSD is transmitted to ...Bartonella henselae bacteria, the causative agent of cat-scratch disease or bartonellosis Bartonella sp. are known to be spread by vectors such as fleas , which are part of the transmission cycle for cat scratch disease and the human body louse , the vector for transmission of Trench fever (3).The epidemiological characteristics and clinical findings are shown in Table 1.A total of 56 patients who developed a scalp eschar and occipital and/or cervical lymph node enlargement after receiving a tick bite were enrolled in this study (Fig. 1).The tick bite distribution was bimodal, with one peak in the spring (31 out of 56, 55.4%) and one peak in the autumn (17 out of 56, 30.3%; Fig. 2).Bartonella henselae) immunologic and inflammatory disorders: cryoglobinemia, essential mixed cryoglobinemia; autoimmune hemolytic anemia; paroxysmal nocturnal hemoglobinuria; thrombotic thrombocytopenic purpura; hemolytic uremic syndrome .

A scab or pustule at the scratch site.Bartonella henselae is a gram-negative rod transmitted to humans by the bite or scratch of an infected animal, often a young cat or kitten. Regional lymphadenopathy is the predominant nonocular finding.Bartonella spp. are gram-negative alphaproteobacteria of the family Bartonellaceae that infect a wide range of animal hosts, including humans ( Boulouis et al., 2005 ). Both fleas and ticks transmit Bartonella spp. although fleas are recognised as the major vector of the key zoonotic Bartonella species, Bartonella henselae ( Chomel et al., 2006 ).
