Potential Parasite Induced Host Mortality in Northern Bobwhite ( Colinus virginianus ) From the Rolling Plains Ecoregion of West Texas
2018Co-Authors: Matthew Z. Brym, Cassandra Henry, Ronald J. KendallAbstract:Anecdotal reports of Northern bobwhite quail (Colinus virginianus) exhibiting strange behavior have raised suspicions of parasite induced host mortality (PIHM) in the Rolling Plains of West Texas. In 2017, we received 11 bobwhite carcasses associated with such reports and found parasites in all of these specimens. While further research is needed to evaluate the impact of parasites on bobwhite, these reports provide a valuable supplement to on-going investigations of PIHM in bobwhite from the Rolling Plains of West Texas.

Molecular identification and characterization of partial COX1 gene from caecal worm (Aulonocephalus pennula) in Northern bobwhite (Colinus virginianus) from the Rolling Plains Ecoregion of Texas.
International journal for parasitology. Parasites and wildlife, 2017Co-Authors: Aravindan Kalyanasundaram, Kendall R. Blanchard, Ronald J. KendallAbstract:Abstract Aulonocephalus pennula is a nematode living in the caeca of the wild Northern bobwhite quail ( Colinus virginianus ) present throughout the Rolling Plains Ecoregion of Texas. The cytochrome oxidase 1 (COX 1) gene of the mitochondrial genome was used to screen A. pennula in wild quail. Through BLAST analysis, similarity of A. pennula to other nematode parasites was compared at the nucleotide level. Phylogenetic analysis of A. pennula COX1 indicated relationships to Subuluridae, Ascarididae, and Anisakidae. This study on molecular characterization of A. pennula provides new insight for the diagnosis of caecal worm infections of quail in the Rolling plains Ecoregion of Texas.

Organochlorine pesticides, lead, and mercury in northern bobwhite (Colinus virginianus) and scaled quail (Callipepla squamata) from the rolling plains ecoregion of Texas and Oklahoma
Environmental toxicology and chemistry, 2015Co-Authors: Catherine E. Baxter, Sara Pappas, Michael T. Abel, Ronald J. KendallAbstract:Northern bobwhite (Colinus virginianus) and scaled quail (Callipepla squamata) from the Rolling Plains ecoregion in Texas and Oklahoma were evaluated for organochlorine pesticides, Pb, and Hg. Of all organochlorine pesticides analyzed, only p,p'-dichlorodiphenyldichloroethylene (p,p'-DDE) and p,p'-dichlorodiphenyldichloroethane (p,p'-DDD) were found in a few composite liver samples. Similarly, a small fraction of tissue samples had detectable levels of Hg (liver and breast) or Pb exceeding background concentrations (femur). Lead concentrations in a few individuals fell within the range associated with moderate toxicity.

Effects of Tissue Collection Methods on Morphometrics and Survival of Captive Neonatal Northern Bobwhite
Journal of Wildlife Management, 2009Co-Authors: Kristine O. Evans, Loren W. Burger, William E. Palmer, Brant C Faircloth, John P. CarrollAbstract:Abstract We assessed effects of tissue collection methods (i.e., patagial microbiopsy and down feathers) and chick age at sampling on morphometrics and 21-day survival of 600 captive neonatal northern bobwhite (Colinus virginianus). We observed minimal effects on morphometrics and no difference in survival among patagial microbiopsy (x ¯ = 0.96 ± 0.03), down feathers (x ¯ = 0.92 ± 0.04), and control (x ¯ = 0.86 ± 0.05) methods. DNA analysis from patagial microbiopsy, down feather, and egg tooth samples showed greater concentrations of DNA from patagial microbiopsy (x ¯ = 10.28 ± 1.74 µg/ml) than either down feather (x ¯ = 4.10 ± 1.74 µg/ml) or egg teeth (x ¯ = 2.35 ± 1.74 µg/ml).

Ten microsatellite loci from Northern Bobwhite ( Colinus virginianus )
Conservation Genetics, 2008Co-Authors: Brant C Faircloth, William E. Palmer, Nancy A. Schable, Travis C. Glenn, Theron M. Terhune, John P. CarrollAbstract:Ecological studies using microsatellite data often require the selection of an optimal marker set for use in parentage and relatedness inference. Commonly, this requires a candidate pool of microsatellite markers from which several are selected to ensure data are acquired efficiently and accurately. We developed 10 microsatellite loci for use with Northern Bobwhite (Colinus virginianus) and tested these loci using individuals collected from two distinct populations in GA and VA. Our new markers yielded seven alleles/locus (range: 2–16) in the Georgia population and six alleles/locus (range: 2–13) in the Virginia population. Exclusionary power of all markers in each population with both parents unknown was >0.98. These microsatellite loci should be combined with previously developed markers to select an optimal set for use in subsequent analyses of parentage and relatedness.

Tetranucleotide and dinucleotide microsatellite loci from the northern bobwhite ( Colinus virginianus )
Molecular Ecology Notes, 2004Co-Authors: Nancy A. Schable, William E. Palmer, John P. Carroll, Brant C Faircloth, Leonard A. Brennan, L. Wes Burger, Cris Hagen, Travis C. GlennAbstract:We describe polymerase chain reaction (PCR) primers and conditions to amplify eight dinucleotide, one trinucleotide and 14 tetranucleotide microsatellite DNA loci isolated from the northern bobwhite ( Colinus virginianus ). The PCR primers were tested on 16 individuals collected from a population located within the Red Hills region of south Georgia and north Florida. The 23 primer pairs developed in this study yielded an average of 6.5 alleles per locus (range 2–11), an average observed heterozygosity of 0.47 (range 0.06–0.94) and average polymorphic information content of 0.60 (range 0.06–0.85).

Helminth Survey of the Northern Bobwhite (Colinus virginianus) from the Rolling Plains of Texas, U.S.A.
Comparative Parasitology, 2019Co-Authors: Andrea Bruno, Dale Rollins, David B. Wester, Alan M. FedynichAbstract:The eyes, breast muscle, and internal organs of 128 hunter-shot northern bobwhites (Colinus virginianus) from the Rolling Plains ecoregion of Texas, U.S.A., were examined for helminths. Six species of nematodes, 1 acanthocephalan, and 1 cestode were found in 120 bobwhites, representing 18,205 helminth individuals. Aulonocephalus pennula was the most common (91% prevalence) and numerically abundant (91% of all individuals) species, followed by Oxyspirura petrowi (66% prevalence and 7% of all individuals). Each of the remaining 6 species was rare (

Mesocestoides sp. in Wild Northern Bobwhite ( Colinus virginianus) and Scaled Quail ( Callipepla squamata).
Journal of wildlife diseases, 2018Co-Authors: Bradley W. Kubečka, Dale Rollins, Nicole J. Traub, Vasyl V. Tkach, Taylor R. Shirley, Alan M. FedynichAbstract:Abstract: Mesocestoides spp. have a cosmopolitan distribution with zoonotic potential. Mesocestoides tetrathyridia were found under the pericardial sac, on the surface of the crop, and in the peritoneal cavity of a hunter-harvested Northern Bobwhite (Colinus virginianus) and a Scaled Quail (Callipepla squamata) collected during the 2016–17 quail hunting season in northwest and southern Texas, US respectively. Molecular analysis indicated that the tetrathyridia from the birds likely belonged to an undescribed species and are identical to pretetrathyridium stages recently found in Scincella lateralis skinks in Oklahoma. This is the first report of Mesocestoides from North American birds.

Survey for Trichomonas gallinae in Northern Bobwhites (Colinus virginianus) from the Rolling Plains Ecoregion, Oklahoma and Texas, USA
Journal of wildlife diseases, 2015Co-Authors: Andrea Bruno, Kathryn E. Purple, Richard W. Gerhold, Alan M. Fedynich, Dale RollinsAbstract:Northern Bobwhites (Colinus virginianus) have been in decline throughout the southeastern US. Prevalence of Trichomonas gallinae in wild bobwhites is unknown, although T. gallinae caused morbidity and mortality in experimentally infected bobwhites. Many species of Columbidae (pigeons and doves) in Texas are hosts to T. gallinae. Bobwhites potentially may become exposed to this protozoan through supplemental feed or water sources contaminated by columbids infected with T. gallinae. All of 506 bobwhites collected in Oklahoma and Texas, 2011-13, were PCR negative for T. gallinae. These data suggest T. gallinae is not contributing to the population decline of bobwhites in this region.
