High Prevalence of Bartonella henselae and Bartonella quintana Antibodies in Croatian Patients Presenting with Lymphadenopathy

Abstract

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.

Bartonella henselae IgM seropositivity in both adult and pediatric patients with diverse clinical conditions in Turkey

“…In our study 72% (34/46) of samples to be tested for the presence of B. henselae were sent between September and March, compatible with data from previous studies [5,6,18]. Many authors considered that seasonal changes in animal reproductive behavior or flea seasonality may be an explanation for this seasonal preference [1,6,20].…”

“…In the present study, 59% of the seropositive patients were above the age of 18, while 41% were under the age of 18. Studies conducted by Sun et al [19] and by Vilibic-Cavlek et al [20] showed similar results suggesting that Bartonella infection may occur in various age groups. Besides, we observed no significant difference in the IgM seropositivity between males (47.4%) and females (41.5%), consistent with other published studies [7,18,21].…”

Survey of Toxoplasma gondii and Neospora caninum, haemotropic mycoplasmas and other arthropod-borne pathogens in cats from Albania

“…Human disease associated to infection with Bartonella species as well as seropositivity to Bartonella spp. has been described from some countries in the Balkans [ 66 , 67 ] but yet not from Albania. The prevalence of Bartonella infection in cats in the Balkan region is largely unknown.…”

Bartonella henselae en niños con adenitis regional atendidos en un hospital nacional del Perú, 2012

“…Se reportan casos de B. henselae en niños con adenitis regional en una muestra amplia de casos. La frecuencia de serología positiva hallada fue superior a otros estudios en niños con adenitis sospechosa por B. henselae quienes reportan frecuencias de 40,4 hasta 73,6% (10)(11)(12) , mielitis, absceso paravertebral; compromiso abdominal como granulomas y microabscesos hepatoesplénicos; compromiso ocular como síndrome óculoglandular de Parinaud, neuritis óptica y retinitis; compromiso pulmonar como neumonitis o derrame pleural. También se reportan endocarditis, pericarditis, púrpura trombocitopénica, anemia hemolítica no inmune, y manifestaciones cutáneas como angiomatosis bacilar y sarpullido (18)(19)(20)(21) .…”
