Description
| - Tažní ptáci mohou být zapojeni do roznosu patogenních mickoorganizmů jako jejich biologičtí nebo mechaničtí nosiči, anebo přenašeči infikovaných ektoparazitů (klíšťat). Četné mikroorganizmy patogenní pro homeotermní obratlovce včetně člověka jsou spojovány s tažnými ptáky, např. některé arboviry (alfaviry východní a západní koňské encefalomyelitidy, Sindbis, flaviviry West Nile a encefalitidy St.Louis), virus influenza A, virus nemoci Newcastle, herpesvirus kachního moru, Chlamydophila psittaci, Anaplasma phagocytophilum, Borrelia burgdorferi s.l., Campylobacter jejuni, Salmonella enterica, Pasteurella multocida, Mycobacterium avium, Candida spp., a ptačí hematozoa. Účinnost roznosu patogenních mikroorganizmů však závisí na řadě biotických a abiotických faktorů, které ovlivňují přežití/zánik patogenního agens v novém biotopu čí ekosystému. (cs)
- Migratory birds might be involved in dispersal of microorganisms as their biological or mechanical carriers, or carriers of infected hematophagous ectoparasites (ixodid ticks). Many microorganisms pathogenic to homeothermic vertebrates including humans have been associated with migrating birds, e.g. some arboviruses (Eastern and Western equine encephalomyelitis and Sindbis alphaviruses, West Nile and St.Louis encephalitis flaviviruses), influenza A virus, Newcastle disease virus, duck plague herpesvirus, Chlamydophila psittaci, Anaplasma phagocytophilum, Borrelia burgdorferi s.l., Campylobacter jejuni, Salmonella enterica, Pasteurella multocida, Mycobacterium avium, Candida spp., and avian hematozoans. The efficiency of dispersal of pathogenic microorganisms depends on a wide variety of biotic and abiotic factors affecting the survival of the agent in, or disappearance from, a habitat or ecosystem in a new geographic area.
