Kurzrasenweide und Ochsenmast: Ergebnisse zur Entwurmung und Aufwuchshöhe in der ersten Weideperiode

Im Rahmen eines Mastversuches auf Kurzrasenweiden mit drei Wuchshöhen (niedrig, mittel, lang) wurde der Kot von 24 Ochsen analysiert. Die Entwurmung erfolgte im ersten Jahr in der 8., im zweiten Jahr in der 3. und 18. Woche. Die Ochsen der niedrigen Aufwuchsöhe hatten schlechtere Wachstumsraten

Fleas as parasites of the family Canidae

Historically, flea-borne diseases are among the most important medical diseases of humans. Plague and murine typhus are known for centuries while the last years brought some new flea-transmitted pathogens, like R. felis and Bartonella henselae. Dogs may play an essential or an accidental role in the natural transmission cycle of flea-borne pathogens. They support the growth of some of the pathogens or they serve as transport vehicles for infected fleas between their natural reservoirs and humans. More than 15 different flea species have been described in domestic dogs thus far. Several other species have been found to be associated with wild canids. Fleas found on dogs originate from rodents, birds, insectivores and from other Carnivora. Dogs therefore may serve as ideal bridging hosts for the introduction of flea-borne diseases from nature to home. In addition to their role as ectoparasites they cause nuisance for humans and animals and may be the cause for severe allergic reactions

New Hemodialysis Access System

A new blood access system for hemodialysis (HD) addresses the major shortcomings of current accessing techniques and helps overcome patient adversity with available choices. The system uses new methods, devices and compositions comprising several novel elements: (1) totally implanted port, elementally simple in design, small and robust with improved safety features, (2) engineered transcutaneous tissue tract (TTT) to precisely guide a tubular conduit to engage the implanted port, (3) viscoelastic gel prophylaxis for internal passages and surface interfaces of the port and TTT, (4) the tool kit aligns the TTT with the port and initiates TTT formation at the time of port placement, (5) an integrated external bloodline circuit comprising the interface between the implanted port and HD machine which can be reused for several treatment sessions. The system provides bloodless, painless, and fail-safe connections with redundant sealing along the complete blood path. It is substantially more robust than current access options and more convenient to use. TTT construct is durable, permanently aligned and fixed to the port enabling non-compromised tissue integrity during access penetration. A bullet-pointed tubular assembly enters and passes through the TTT confining the tubular device to advance towards the port and entering it to engage a solid tactually sensed stop indicating the correct position. The system may be used within a few days of port placement. The access is unobtrusive and preserves patient self-image.</jats:p
