Gut parasites that can infect man are widespread in domestic and wild animals in Norway

18.02.2009
The gut protozoans Giardia duodenalis and various species of Cryptosporidium are extremely contagious single-celled parasites liable to cause digestive disease in both man and animals.

Some species and genotypes of Cryptosporidium and Giardia are important zooneses, as they occur in both animals and man. Zooneses are diseases that may be transmitted between animals and people.

Inger Sofie Hamnes showed in her doctorate that parasites of the groups Cryptosporidium and Giardia are extremely widespread in domestic animals, wild deer species and the red fox in Norway. Genotyping of Giardia isolated from elk, wild reindeer and red foxes showed that Giardia duodenalis in these animals may potentially infect humans.

Hamnes studied the occurrence of Cryptosporidium and Giardia in calves, dogs, wild deer species (elk, wild reindeer, red deer, roe deer and Svalbard reindeer), piglets and red fox in Norway, by analysis of scats.

Her studies showed that Cryptosporidium is common among young dogs, calves and piglets and that the parasites also occur to a lesser extent in roe deer, elk, red deer and the red fox. Cryptosporidium was not found in wild reindeer or Svalbard reindeer.

Giardia was more common than Cryptosporidium in calves, and the occurrence of both parasites varied with the calves' age, geographic occurrence, season, and the cleaning frequency of pens. Among wild deer species, Giardia was more common than Cryptosporidium, while roe deer and elk had the highest occurrences of both parasites.

The presence of Cryptosporidium and Giardia in dogs varied with age and geographic location. There was a higher occurrence of diarrhoea in piglets from litters that were infected by Cryptosporidium than in litters free of infection. The occurrence of both parasites was low in the red fox, however, the geographic distribution was extensive.

The results of these studies show that parasites of the groups Cryptosporidium and Giardia are widely distributed among both domestic and wild animals in Norway. Grazing animals may represent a source of transmission to man through drinking water, although people can also become infected through direct contact with infected animals.

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
