“…henselae Regnery et al, or the agent of Cat Scratch Disease, infection has also been described in Peruvian individuals (Huarcaya et al 2002). B. henselae is maintained by felines and transmitted by contact with infectious cat ßea, Ctenocephalides felis (Bouché ), feces through scariÞcation or potentially by bite of a bacteremic host (Billeter et al 2008a;Westling et al 2008). B. elizabethae, a known cause of endocarditis in a human patient, was isolated from a Rattus norvegicus (Berkenhout) rat in the Huayllacallán Valley in Ancash, Peru during a study to determine potential animal reservoirs in the homes of individuals diagnosed with bartonellosis .…”

A total of 103 ticks, collected from canines, horses, donkeys, and snakes from Peru, were screened for the presence of Bartonella DNA by polymerase chain reaction analysis. Bartonella DNA was detected in two ticks using Bartonella 16S-23S intergenic spacer region primers and in an additional two ticks using Bartonella NADH dehydrogenase gamma subunit gene (nuoG) primers. Bartonella rochalimae Eremeeva et al., B. quintana Schmincke, and B. elizabethae Daly et al. DNA was detected in a Rhipicephalus sanguineus Latreille (Acari: Ixodidae) female tick removed from a dog and B. quintana DNA was present in a Dermacentor nitens Neumann (Acari: Ixodidae) pool of five larvae, one nymph, and one adult male tick collected from donkeys. This is the first study to report the detection of B. rochalimae, B. quintana, and B. elizabethae DNA in ticks from Peru. Further investigations must be performed to decipher the role ticks may play in the transmission of Bartonella species.

“…Seroepidemiological studies have demonstrated the worldwide distribution of B. henselae infection in domestic cats with antibody prevalence from 5-86% (Podsiadly et al, 2002;Fabbi et al, 2004;Boulouis et al, 2005;Celebi et al, 2009). Transmission to humans mainly occurs directly by a cat scratch and possibly via a cat bite (Boulouis et al, 2005;Breitschwerdt et al;Westling et al, 2008). In immunocompetent individuals, cat-scratch disease is characterized by a benign regional lymphadenopathy.…”

Between 2007 and 2010, a total of 268 Croatian patients with lymphadenopathy were tested for IgM/IgG antibodies to Bartonella (B.) henselae and B. quintana. Samples from 44.4% patients showed positive IgG antibodies: 35.8% to B. henselae, 6.7% to B. quintana and 1.9% to both Bartonella species. There was no difference in seropositivity between males and females (47.4% vs. 41.5%). Seroprevalence was high in all age groups (40.4-60.9%). Patients from urban and rural areas showed a similar seroprevalence rate (44.1% vs. 44.8%). Positive IgM antibodies were found in 28.3% patients varying from 17.5% and 37.5% among age groups. Most cases were reported from August to March.

“…In this report, the positive titre for anti- B. quintana antibodies (1 : 128) was unexpected, since clinical infections with the bacteria are uncommon [17, 18] and it has not been associated with cat bites previously in Sweden [19, 20]. Infections caused by B. quintana are exclusively seen in patients with actual or recent contact with body lice [21].…”

Cat-bite-induced Francisella tularensis infection with a false-positive serological reaction for Bartonella quintana

Introduction. Tularaemia is caused by infection with Francisella tularensistransmitted via direct contact with an infected hare carcass or indirectly through the bites of vectors, but may be cat-bite-associated as well. Medical history and reliable diagnostic analysis are important in order to differentiate it from other cat-associated infections, e.g. Bartonella spp.Case presentation. A healthy 56-year-old man was examined because of a cat-bite-associated ulceroglandular wound on his right thumb. Nineteen days after the cat bite occurred, a serology test was positive for anti-Bartonella quintana, but negative for anti-F. tularensis. Since Bartonella infections are rare in Sweden, another serology test was analysed 2 weeks later with a positive result for anti-F. tularensis. The patient was treated with doxycycline for 14 days and recovered. The patient was re-sampled after 18 months to obtain a convalescent sample. The acute and the convalescent samples were both analysed at a reference centre, with negative results for anti-Bartonella spp. this time.Conclusion. This case is enlightening about the importance of extending the medical history and re-sampling the patient for antibody detection when the clinical suspicion of cat-bite-associated tularaemia is high. The false-positive result for anti-B. quintana antibodies may have been due to technical issues with the assay, cross-reactivity or both.
