ABSTRACT

Sera from cats and dogs in the UK were tested by ELISA for antibodies to Bartonella henselae. Seropositivity was confirmed in 28 of 69 pet cats (40.6 per cent), 33 of 79 feral cats (41.8 per cent) and three of 100 pet dogs. Reactivity to specific B. henselae antigens was confirmed by Western blotting and demonstrated that consistent antigenic bands were bound by sera from the cats and dogs.

    • "Other studies conducted on populations of stray cats in Europe showed lower seroprevalence values. Barnes et al. found seropositivity in 33/79 (41.8%) cats[10]. A seroprevalence value of 39% was reported in Italy[14]. "

    ABSTRACT: The aim of this study was to determine the prevalence of coinfection with pathogens Bartonella henselae, feline immunodeficiency virus, and feline leukemia virus in stray cats from the area of Novi Sad and Belgrade, Serbia. Each of 60 individual cats was clinically examined and the blood sampled. Therewithal an epidemiological survey was made. Blood sera were separated by centrifugation and serologically tested in order to determine the presence of Bartonella henselae specific antibodies (by direct immunofluorescence assay), feline immunodeficiency virus specific antibodies (by rapid test SNAP Combo) and feline leukemia virus antigens (by rapid test SNAP Combo). Of the 60 cat sera, serologically examined using IFA test, 33 (55%) were positive for the presence of IgG specifi c to B. henselae antigens. A total of 13 (27%) of the 60 tested cat sera were positive for the presence of specific antibodies to FIV antigens. None of the 60 tested cat sera were positive for the presence of FeLV antigen. Of the 33 cat sera which contained IgG antibodies to B. henselae, 6 cat sera also gave a positive reaction to the presence of specific IgG antibodies to FIV; this was a coinfection seroprevalence of 10% in the total population of studied cats. The results obtained in this study indicate the presence of B. henselae and FIV coinfection in cats from Serbia, without FeLV positive cats. An increase in the manifestations of clinical symptoms in cats in which the serological tests determined coinfection with B. henselae and FIV is evident compared to those seropositive only to B. henselae.

    • "In Denmark , Chomel et al. (2002) detected B. henselae antibodies in 46.7% of the cats studied. The B. henselae seroprevalence reported in cats was similar in Denmark and other European countries (Barnes et al., 2000; Gurfield et al., 2001). Lower percentages of B. henselae seroprevalence in cats were reported in Switzerland (8.3%) and in Germany (15%) (Glaus et al., 1997; Haimerl et al., 1999). "

    ABSTRACT: Bartonella henselae is considered an emerging pathogen of veterinary and medical interest that can be occasionally transmitted to humans. Cats are considered to be the only reservoir host for B. henselae. In this study, we used a nested-PCR assay to investigate the prevalence of B.henselae and Bartonella clarridgeiae DNA in peripheral blood samples, fine needle lymph node aspirate specimens and oral swabs from 85 cats in order to develop an easy diagnostic strategy for the selection of infection-free cats that are being considered as pets, especially for immunocompromised patients. Overall, molecular analysis showed that 71 cats (83.5%) tested PCR positive for the presence of B. henselae DNA. PCR amplification of DNA B. henselae produced positive products from lymph node aspirate specimens (62/85; 72.9%) similar to those obtained from blood samples (60/85; 70.6%) and higher than those from oral swabs (51/85; 60%) of cats. No PCR product was obtained for B. clarridgeiae. The simultaneous analysis of three different clinical samples in our study increased the diagnostic possibilities for B. henselae infection in the examined cats from 60-72.9% to 83.5%. Lymph node aspirates were found to be the most effective clinical samples for the detection of B. henselae and blood samples were the next best. Oral swab samples were used in this study with good results when considered in combination with blood and/or lymph node aspiration. The use of nested-PCR assay on these three clinical samples may enhance the diagnostic sensitivity for bartonellosis in cats irrespective of the clinical status of animals.

    • "Recently, B. henselae DNA has been amplified and sequenced from the liver of a dog with peliosis hepatitis [37] and a dog with granulomatous hepatitis [24] and from the blood of three dogs with either fever, thrombocytopenia or neurologic dysfunction [51]. Three canine serosurveys carried out in Hawaii, Japan and the United Kingdom describe B. henselae seroprevalence of 6.5% [20], 7.7% [61] and 3% [4], respectively. In Japan, B. henselae PCR positive results were also reported from peripheral blood, nail clippings and oral swabs in 15% of the dogs studied [61]. "

    ABSTRACT: In contrast to the large body of literature regarding Bartonella henselae in humans and cats, there is little information about B. henselae as an infectious agent in dogs. Due to the paucity of information regarding the B. henselae serology in dogs, we performed a cross-sectional serosurvey using B. henselae antigen in order to compare the seroprevalence between sick and healthy dogs from the south-eastern USA. Ninety-nine sera were collected from clinically healthy dogs. Three hundred and one sera from sick dogs were submitted to North Carolina State University for serologic screening against a panel of arthropod-transmitted organisms. Serological tests were performed using B. henselae (Bh), Rickettsia rickettsii (Rr), Ehrlichia canis (Ec), Bartonella vinsonii subspecies berkhoffii (Bvb), Babesia canis (Bc) and Borrelia burgdorferi (Bb) antigens. Serum B. henselae IgG antibodies were detected in 10.1% of healthy dogs and in 27.2% of sick dogs. The difference in seroprevalence between the two groups was statistically significant. The majority of seroreactive dogs (80%) had low titers of 1:64 or 1:128. In healthy dogs, seroprevalence for Rr was 14.1% and for Bvb was 1%. In sick dogs, Rr seroprevalence was 29.7%, Ec 6.5%, Bvb 4.7%, Bb 1.7% and Bc was 0.85%. Of the sick dogs that were seroreactive to B. henselae antigens, 40.6% were also seroreactive to Rr, 15.0% reactive to Bvb antigens, 14.8% reactive to Ec antigens, 1.8% reactive to Bc antigens and 1.75% reactive to Bb antigens. Sera from dogs experimentally infected with B. vinsonii subsp. berkhoffii, E. canis or R. rickettsii did not cross react with B. henselae antigens, by IFA testing. This study indicates that B. henselae IgG antibodies are prevalent in healthy and sick dogs living in the south-eastern USA. Nevertheless, further studies are needed to evaluate the epidemiological, clinical and zoonotic relevance of B. henselae infection in dogs.
