Bartonella spp. is an etiologic agent of vector-borne infections. Bartonella spp. was searched for in adult Ixodes ricinus ticks removed from dogs and cats using specific polymerase chain reaction (PCR) and sequence analysis of gltA gene. Bartonella henselae DNA was detected in 5 of 102 tested ticks. All PCR-positive ticks were removed from dogs. Four of(More)
To investigate the role of B. henselae in patients with symptoms suggesting neuroborreliosis, serum and cerebrospinal fluid samples were tested with serological and PCR methods. Among 17 examined patients, in 12 cases Borrelia burgdorferi infections were detected, in 1 case Bartonella henselae infection was ascertained, and in two patients mixed B.(More)
We report the case of rickettsial eschar-associated spotted fever, most probable due to Rickettsia raoultii, an emerging pathogen, which was previously described in patients with tick-borne lymphadenopathy (TIBOLA), also called Dermacentor-borne necrosis erythema and lymphadenopathy (DEBONEL). The pathogenicity of R. raoultii is not well established. The(More)
The presence of antibodies to Rickettsia conorii, R. helvetica, R. felis, R. slovaca, R. sibirica, and R. massiliae in sera of 129 forest workers from northeastern and southern Poland was assayed by indirect immunofluorescence. Previous environmental studies revealed presence of spotted fever group (SFG) rickettsiae in ticks collected from these areas.(More)
From 1992 till the end of 1994, three epidemics of Q fever among people have been recognised in Poland. In 1992 the outbreak of Q fever was detected at the farm near Jawor in Legnica district. Coxiella burnetii infection was recognized serologically in 25 persons (27 tested). Titres of serum antibodies ranged from 8 to 256. It has been found that cattle(More)
It has been found that B. burgdorferi bacteria multiply in mouse fibroblasts. Mouse fibroblast of the L-929 cell line was inoculated with less than 10 up to 10(4) B. burgdorferi cells and incubated for 2-10 days at 35 degrees C in microaerophilic conditions. Within 2 days, visible growth was observed. The bacteria were present in growth medium and on/in(More)
Apoptosis is a genetically controlled mechanism of cell death involved in the regulation of tissue homeostasis. The aim of this study was to investigate the influence of Borrelia afzelii, Coxiella burnetii, and Bartonella henselae bacteria on apoptosis measured as the level of caspase 3 activity in human fibroblast cells HEL-299. Our findings show that C.(More)
The aim of the study was to evaluate a one-step procedure using an ELISA test of high specificity and a two-step procedure using immunoblot as a confirmation test, and to compare the results of serological testing with detection of bacterial DNA and living spirochetes. Sera, synovial (SF) and cerebro-spinal fluids (CSF) were obtained from 90 patients with(More)
Excessive cicatrisation or epidural fibrosis in the operative field is an inappropriate event occasionally occurring after neurosurgical procedures (i.e., spine procedures and craniotomies). This excessive process may disturb the postoperative course and render reoperations more difficult and risky. The literature describes this phenomenon as accompanying(More)
