The seroepidemiology of Lyme borreliosis in zoo animals in Germany.

We conducted the first seroepidemiological study to evaluate the exposure of zoo animals to Borrelia burgdorferi s.l. in German zoos and wildlife parks. A total of 1487 individuals representing 148 ungulate and carnivore species belonging to 19 families were examined using a non-species dependent ELISA. Specific antibodies were detected in 154 (10.4%) animals; 168 (11.3%) sera produced borderline results. The percentage of seropositive individuals was related to species and origin (zoo), and increased with age of the animals. Sex and season did not influence seroprevalence. Examination of 600 ticks (Ixodes ricinus; caught from vegetation in the zoos) by darkfield microscopy and indirect immunofluorescence technique revealed infection rates within the range typical for Central Europe. The results substantiate that there is an infection risk for zoo animals. A differential diagnosis of Lyme borreliosis should be taken into account in case of suspicious clinical symptoms and possible contact to ticks.

Chronically implanted intrafascicular recording electrodes.

A newly designed intrafascicular electrode for chronic neural recording was studied by implanting 12 electrodes in the radial nerves of 6 cats for 6 months. Action potentials were monitored at specified intervals throughout the experiment. The number and size of the signals recorded suggest that this type of electrode provides information that is appropriate for feedback control in functional electrical stimulation (FES) systems. Histology of the nerve revealed that the implants are biocompatible and that little damage is caused by the presence of the electrode.

Synovial fluid examination in hyperuricemic psoriatic patients.

Aspiration of the first metatarsophalangeal joint in asymptomatic hyperuticemic psoriasis was performed in order to see whether there are specific findings which could help to predict who is prone to develop gout and to find out whether a distinction can be established between psoriasis and gouty arthritis. Since crystals were not found, it seems that the aspiration of the first metatarsophalangeal joint is not likely to yield monosodium urate crystals and is not contribute to the differential diagnosis.
