“…Similarly, in humans, signs of botulism progress in a descending (head to feet) and symmetrical pattern (Smith and Sugiyama, 1988;Tacket and Rogawski, 1989). However, the onset of clinical signs in avian botulism occurs in the opposite direction, with loss of leg function occurring first with a gradual progression to complete flaccid paralysis (Wobeser, 1997).…”

ABSTRACT:Since 1999, large-scale mortalities of fish-eating birds have been observed on the Great Lakes, and more specifically on Lake Erie. Type E botulism has been established as the primary cause of death. The mechanism of type E botulism exposure in fish-eating birds is unclear. Given that these birds are thought to eat live fish exclusively, it seems likely that their prey play a key role in the process, but the role of fish as potential transport vectors of botulinum neurotoxin type E (BoNT/E) to birds has not been adequately investigated. Between June 2003 and April 2004 a methodological model for exposing fish to Clostridium botulinum was developed and used to compare the sensitivity of rainbow trout (Oncorhynchus mykiss), round goby (Neogobius melanostomas), walleye (Stizostedion vitreum), and yellow perch (Perca flavescens) to four doses (0, 800, 1,500, and 4,000 Mouse Lethal Doses) of Clostridium botulinum type E neurotoxin. Each fish species expressed unique changes in both behavior and skin pigmentation prior to death. Yellow perch survived significantly longer (P,0.05) than the three other species at all toxin treatments. Results of this study suggest that live fish can represent a significant vector for transfer of BoNT/E to birds.

“…Three common pathogenic fungi were found: M. gallinae, which can cause favus (ringworm) in poultry [19]; Ca. albicans, which can cause candidiasis and death in young sparrows (Passer domesticus and P. montanus) [22,46]; and A. flavous, an important cause of avian aspergillosis and aflatoxicosis [68].…”

“…It is well established that free-living birds, including migratory species, have the potential to disperse certain pathogenic microorganisms (Keymer, 1958;Pavlovsky and Tokarevich, 1966;McDiarmid, 1969;Davis et al, 1971;Lvov and Ilichev, 1979;Cooper, 1990;Hubá lek, 1994;Nuttall, 1997;Wobeser, 1997). The potential for transport and dissemination of certain pathogenic microorganisms by migratory birds is of concern and is the subject of increased vigilance recently, stimulated by the occurrence and unprecedented spread of West Nile virus (WNV) in North America since 1999, where free-living birds have played a significant role (Anderson et al, 1999;Garmendia et al, 2000;Rappole et al, 2000;Bernard et al, 2001;Komar et al, 2002Komar et al, , 2003aDupuis et al, 2003;Male, 2003;Rappole and Hubálek, 2000).…”

The potential for transport and dissemination of certain pathogenic microorganisms by migratory birds is of concern. Migratory birds might be involved in dispersal of microorganisms as their biological carriers, mechanical carriers, or as carriers of infected hematophagous ectoparasites (e.g., ixodid ticks). Many species of microorganisms pathogenic to homeothermic vertebrates including humans have been associated with free-living migratory birds. Migratory birds of diverse species can play significant roles in the ecology and circulation of some arboviruses (e.g., 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 sensu lato, 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.
