“…Although habitat loss associated with intensive agricultural practices has been considered as a major contributor, quail declines have continued even in areas of apparently suitable habitat during favorable weather conditions [3] . The involvement of infectious agents has been investigated, but studies have failed to identify any pathogens with the potential to kill large numbers of quail [4] , [5] . This ongoing decline, termed “Idiopathic Quail Decline” underscores the need for a holistic approach to the study of quail health [3] , [6] .…”

The northern bobwhite (Colinus virginianus) is an ecologically and economically important avian species. At the present time, little is known about the microbial communities associated with these birds. As the first step to create a quail microbiology knowledge base, the current study conducted an inventory of cultivable quail tracheal, crop, cecal, and cloacal microbiota and associated antimicrobial resistance using a combined bacteriology and DNA sequencing approach. A total of 414 morphologically unique bacterial colonies were selected from nonselective aerobic and anaerobic cultures, as well as selective and enrichment cultures. Analysis of the first 500-bp 16S rRNA gene sequences in conjunction with biochemical identifications revealed 190 non-redundant species-level taxonomic units, representing 160 known bacterial species and 30 novel species. The bacterial species were classified into 4 phyla, 14 orders, 37 families, and 59 or more genera. Firmicutes was the most commonly encountered phylum (57%) followed by Actinobacteria (24%), Proteobacteria (17%) and Bacteroidetes (0.02%). Extensive diversity in the species composition of quail microbiota was observed among individual birds and anatomical locations. Quail microbiota harbored several opportunistic pathogens, such as E. coli and Ps. aeruginosa, as well as human commensal organisms, including Neisseria species. Phenotypic characterization of selected bacterial species demonstrated a high prevalence of resistance to the following classes of antimicrobials: phenicol, macrolide, lincosamide, quinolone, and sulphate. Data from the current investigation warrant further investigation on the source, transmission, pathology, and control of antimicrobial resistance in wild quail populations.

“…For example, a serosurvey that included large numbers of California quail ( n = 2,156) and Gambel's quail ( n = 1,488) revealed 27.6% and 9.5% seroprevalence, respectively, from 2003 to 2007, although temporal variation was not assessed (Wheeler et al 2009). Additional serosurveys, including California quail, Gambel's quail, northern bobwhite, and scaled quail ( Callipepla squamata ), also support interspecies variation in WNV seroprevalence, potentially reflecting increased resistance to WNV‐associated morbidity and mortality in some species (Urban et al 2013, Reisen and Wheeler 2016). This interspecies variation in seroprevalence is supported by results of experimental infection trials among a variety of galliform species (Komar et al 2003; Reisen et al 2005, 2006; Wheeler et al 2009), although variations in seroprevalence in avian populations may also be affected by year‐to‐year differences in transmission (e.g., vector dynamics, environmental conditions that may facilitate or dampen transmission) as well as geographic variability.…”

Our current understanding of West Nile virus in upland game birds

Since its introduction to the United States in 1999, West Nile virus (WNV) rapidly spread and is now endemic throughout much of North America. West Nile virus has impacted many North American birds, including suspected population-level declines. However, the potential effects of WNV on upland game bird species remain largely unknown. We reviewed the published literature on WNV infection in upland game birds, with the majority comprised of experimental infection trials, serologic surveys, and natural infection reports. Early WNV research indicated that some species within Galliformes are not susceptible to WNV-associated disease, but reports were primarily based on studies in domestic fowl with small sample sizes. Research on greater sage-grouse (Centrocercus urophasianus) and ruffed grouse (Bonasa umbellus) confirmed both species are highly susceptible to WNV-associated morbidity and mortality, which highlights the need to better understand the potential effects of WNV on other upland game bird species. Serological data using primarily hunter-harvested, greater sage-grouse samples revealed low seroprevalence among several populations, indicating WNV may pose a risk to greater sage-grouse populations. Currently, data are lacking on the effects of WNV in wild turkeys (Meleagris gallopavo), for which low recruitment rates and depressed population numbers have been documented across parts of the eastern United States. Despite low virulence of WNV in experimentally-infected domestic turkeys, sporadic cases of WNV-associated morbidity are reported in wild turkeys.

“…To address the concern regarding the potential causes of the quail population decline, the Rolling Plain Quail Research Foundation (RPQRF) initiated a comprehensive and collaborative program named "Operation Idiopathic Decline" (OID) to investigate the status of infectious diseases and environmental factors in the Rolling Plains ecoregion of Texas and Oklahoma (http://www.quailresearch.org/projects1/). Under the OID program, a few recent studies have reported surveys on toxins, viral and bacterial agents, and helminth communities (Baxter et al 2015;Bruno et al 2015;Dunham et al 2014;Moore et al 2013;Su et al 2014;Turaga et al 2016;Urban et al 2013;Xiang et al 2013). The present study was part of the OID program aimed to gain knowledge on the prevalence of major protozoan parasites (protists) in northern bobwhites and scaled quail in the Rolling Plains ecoregion.…”

We developed nested PCR protocols and performed a multiyear survey on the prevalence of several protozoan parasites in wild northern bobwhite (Colinus virginianus) and scaled quail (Callipepla squamata) in the Rolling Plains ecoregion of Texas and Oklahoma (i.e. fecal pellets, bird intestines and blood smears collected between 2010 and 2013). Coccidia, cryptosporidia, and microsporidia were detected in 46.2%, 11.7%, and 44.0% of the samples (n = 687), whereas histomona and hematozoa were undetected. Coccidia consisted of one major and two minor Eimeria species. Cryptosporidia were represented by a major unknown Cryptosporidium species and Cryptosporidium baileyi. Detected microsporidia species were highly diverse, in which only 11% were native avian parasites including Encephalitozoon hellem and Encephalitozoon cuniculi, whereas 33% were closely related to species from insects (e.g. Antonospora, Liebermannia, and Sporanauta). This survey suggests that coccidia infections are a significant risk factor in the health of wild quail while cryptosporidia and microsporidia may be much less significant than coccidiosis. In addition, the presence of E. hellem and E. cuniculi (known to cause opportunistic infections in humans) suggests that wild quail could serve as a reservoir for human microsporidian pathogens, and individuals with compromised or weakened immunity should probably take precautions while directly handling wild quail.
