An IgG (H+L)-ELISA was applied as a screening test for antibodies against Chlamydia (C.) psittaci in sera of goats and sheep in Namibia. In 576 (27.3%) of a total of 2,107 sera (299 = 25.2% of 1,185 caprine and 277 = 30.0% of 922 ovine sera) chlamydial antibodies could be detected. 86% of all farms tested revealed seropositive animals. Chlamydial infections(More)
Various polymorphisms of the X-chromosomal monoamine oxidase A (MAO-A) gene were investigated for association with affective disorders. However, none of the studied variants could consistently be associated with either major depressive or bipolar affective disorder. Recently, a positive association between panic disorder and a novel functional repeat(More)
Pulsed field gel electrophoresis was used for differentiation of Coxiella burnetii isolates derived from animals in Europe and one from Namibia. Previously published data on isolates from North America demonstrated four groups with distinct banding patterns. Fingerprints of prototype isolates as references confirmed four different cleavage patterns upon(More)
OBJECTIVE Familial occurrence of tardive dyskinesia (TD) and schizophrenia has been hypothesized to confer risk to the development of TD. We investigated these hypotheses in a large patient sample applying standardized methods for phenotype characterization. METHOD Two hundred and twenty-two patients with a diagnosis of schizophrenia or schizoaffective(More)
Rabbit hemorrhagic disease (RHD) is a relatively new and economically important viral disease of wild and domestic rabbits and hares. Characteristic lesions are abundant hemorrhages in many organs, e.g. trachea, lung, liver, kidney, spleen, peritoneum and pleura. In the past few years epidemic outbreaks of this disease have been observed worldwide. The aim(More)
Acute bacterial prostatitis caused by common urinary tract pathogens is an infrequent disease, and diagnostic difficulties are rarely encountered. On the other hand, chronic prostatitis is a common disease requiring rather elaborate diagnostic procedures. We applied the localization protocol of the four-specimen technique and combined quantitative(More)
During the last years, the validity of classic case control studies in psychiatric genetic research has been increasingly under question due to the risk of population stratification problems inherent to this type of association study. By consequence, the application of family-based association studies using parent-offspring trios has been strongly(More)
A PCR approach (transposon PCR) with primers based on repetitive transposon-like sequences, which--depending on the isolate--were found at a minimum frequency of 19 on the C. burnetii genome, was established for the highly sensitive and specific detection of C. burnetii. This study describes the analytical detection of C. burnetii in milk, which requires a(More)
