[prevalence of antiborrelia antibodies in two populations: various interpretations of the same data].the objective of the work was to test whether differently formulated hypotheses, when using correct statistical methods, and the same data lead to the same results. the work pertains to the interpretation of the prevalence of antiborrelia antibody levels in more or less high risk populations. group: a group of 200 blood donors from prague (100 men, mean age 33.5 years and 100 women mean age 24.4 years) and 71 subjects with a higher risk of contact with ticks infected with borrelia burgdorferi--f ...200211881295
[informational value of the prevalence of antiborrelia antibodies in a healthy and at risk population].the authors tried to confirm data on the prevalence of antiborrelia antibodies class igm and igg in the local healthy population (200 blood donors) and in subjects with an increased risk of infection (forestry labourers, forestry workers and huntsmen). all blood samples were analyzed in the national reference laboratory for lyme borreliosis cem (lb) in the national institute of public health in prague by the elisa nrlb kc 90 method and in case of a positive result they were confirmed by the west ...200010802944
incidence of spirochetes (borrelia sp.) in the tick ixodes ricinus in the urban environment (capital of prague) between 1994-1997.a total of 12287 ticks were collected from 10 localities of the capital of prague between 1994 and 1997 (2978 ticks in 1994, 5612 ticks in 1995-1996, 3686 ticks in 1997). the presence of borrelia was investigated by the indirect immunofluorescence assay using hyperimmune rabbit sera. the tick infestation ranged between 3.8% and 9.7% (1994), 7.9% and 11.3% (1995), 3.6% and 6.2% (1996) and 4.8% and 9.2% (1997). the results obtained are indicative of a relatively high opportunity for exposure to th ...199910096169
incidence of borrelia garinii and borrelia afzelii in ixodes ricinus ticks in an urban environment, prague, czech republic, between 1995 and 1998.the presence of borrelia burgdorferi sensu lato and its individual genospecies was determined using a single-step polymerase chain reaction in a total of 779 ixodes ricinus ticks collected from an urban park in prague, czech republic. the incidence of borrelia burgdorferi sensu lato was 9.2% in 1995, 3.4% in 1996, 4.5% in 1997 and 2.8% in 1998. the borrelia garinii to borrelia afzelii ratio was 1.4:1 and it did not differ significantly throughout the study period. borrelia burgdorferi sensu stri ...199910482032
higher prevalence of antibodies to borrelia burgdorferi in psychiatric patients than in healthy subjects.borrelia burgdorferi infection can affect the cns and mimic psychiatric disorders. it is not known whether borrelia burgdorferi contributes to overall psychiatric morbidity. the authors compared the prevalence of antibodies to borrelia burgdorferi in groups of psychiatric patients and healthy subjects to find out whether there is an association between this infection and psychiatric morbidity.200211823274
