“…(2015) first documented eye pathology in bobwhites associated with O. petrowi and infection within the Harderian gland. Additionally, Dunham et al., 2014 , Dunham et al., 2015 revealed significant inflammation and petechial hemorrhaging associated with O. petrowi infection. This research, along with the present study, describe a series of detrimental consequences within the Northern bobwhite host when infected with eyeworms.…”

“…A few studies have shown that these parasites do not cause pathological effects or gross lesions ( McClure, 1949 , Pence, 1972 , Ruff and Norton, 1997 ); however, Saunders (1935) observed ocular irritation caused by eyeworm infections. Recently, O. petrowi infections were reported to cause severe inflammation and edema ( Dunham et al., 2014 , Dunham et al., 2015 ). Bruno et al.…”

Debilitating ocular diseases are often reported in avian species. By and large, helminth parasites have been overlooked in avian diseases and regarded as inconsequential. The decline of Northern bobwhite quail (Colinus virginianus) in the Rolling Plains ecoregion of Texas has prompted an investigation of the factors influencing their disappearance. Infection by the eyeworm (Oxyspirura petrowi) has been documented in many avian species; however, the effect it has on its host is not well understood. Heavy eyeworm infection has been documented in Northern bobwhites throughout this ecoregion, leading to eye pathology in this host species. The present study further documents and supports the pathological changes associated with O. petrowi in bobwhites.

“…Dunham et al () identified inconsistencies of other studies in reporting and execution of necropsies of tissues infected with O. petrowi and the potential underreporting of O. petrowi in bobwhites and other galliforms. In a second study, Dunham et al () experimented with various methods of keeping eyeworms alive after removal from bobwhite hosts and infecting bobwhites with O. petrowi . This study provided useful information on the extraction, in vitro culture, and transfer of O. petrowi for future lab and aviary studies on the lifecycle of O. petrowi and its potential effects on individual hosts (Dunham et al ).…”

Helminths and the northern bobwhite population decline: A review

2016

Long-term data from the Breeding Bird Survey and Christmas Bird Count indicate that northern bobwhite (Colinus virginianus; hereafter, bobwhite) populations have declined since 1961 in all but 1 of the 31 states they occupy within the United States. This long-term population decline is largely due to habitat loss. However, several other factors, including parasitism, have been considered as possible contributors or even primary causes of the bobwhite population decline. We review recent research on the helminths that infect bobwhites, particularly in Texas, and compare the bobwhite-helminth system to other galliform-helminth systems. We hypothesize that helminths do not affect bobwhite populations under favorable habitat conditions and that any observed localized population impacts may be proximate causes of the bobwhite population decline rather than ultimate causes of the bobwhite population decline. Helminth survey data provide insufficient evidence of negative effects on individual bobwhites or on their populations. Although surveys provide important data and should continue, experimental studies are the best way to identify the impact that helminths may have on bobwhites at the population level.
