Exempel på protozoa

• However, survival times of excreted viruses and protozoa may be long enough to cause a health risk in schemes for wastewater use.

• A total of 27 genera of parasites (2 fungi, 16 protozoa and 9 metazoa) were recovered.

• Considering their abundance and their potential role, protozoa are undoubtedly active participants within phytotelmata food webs.

• Factors affecting infections of mammals with intraerythrocytic protozoa.

• These limited data suggest that protozoa may be an important food resource for the numerous aquatic metazoa that inhabit the tanks of bromeliads.

• Based on our results, protozoa appear clearly to be of major importance within the aquatic community of tank bromeliads.

• Thus, protozoa may be key organisms in bromeliad microcosms when large amounts of organic matter are present.

• Towards an integrated genetic epidemiology of parasitic protozoa and other pathogens.

• Infections with intraerythrocytic protozoa, therefore, have an adverse effect on concomitant nematode infections.

• Thus, heterotrophic protozoa may act as an essential pathway for dissolved organic matter and as important consumers of bacteria in tank bromeliads.

• One unit of study, which is commonly employed to investigate the population ecology of microparasitic organisms (the viruses, bacteria and protozoa), is the infected host.

• In addition, studies in animal models should include parasite interaction with protozoa and viruses.

• In this respect the transmission resembles that of many intestinal protozoa.

• Clonal structures have often been reported for protozoa.

• For protozoa counting, 2 ml samples of fermenter fluid were taken daily, immediately before the substrate exchange.
