The human head louse is a cosmopolitan ectoparasite and frequently infests many people, particularly school-age children. Due to widespread pyrethroid resistance and the lack of efficient resistance management, there has been a considerable interest in the protection of uninfested people and prevention of reinfestation by disrupting lice transfer. In this study, two nonclinical model systems (in vitro and in vivo) were used to determine the efficacy of the infestation deterrents, Elimax lotion and Elimax shampoo, against human head lice or poultry chewing lice, respectively. With in vitro assessments, female head lice exhibited significantly higher avoidance responses to hair tufts treated ...

USDA National Wildlife Research Center - Staff Publications
White-tailed deer (Odocoileus virginianus) serve as a reservoir for bovine tuberculosis, caused by Mycobacterium bovis, and can be a source of infection in cattle. Vaccination with M. bovis Bacille Calmette Guerin (BCG) is being considered for management of bovine tuberculosis in deer. Presently, no method exists to non-invasively monitor the presence of bovine tuberculosis in deer. In this study, volatile organic compound profiles of BCG-vaccinated and non-vaccinated deer, before and after experimental challenge with M. bovis strain 95–1315, were generated using solid phase microextraction fiber head-space sampling over suspended fecal pellets with analysis by gas chromatography/mass spectrometry. Chromatograms ...
Development Of An In Vivo Exsheathment Assay Of Infective L3 Haemonchus Contortus Larvae In Fistualated Sheep, 2015 University of Rhode Island
Development Of An In Vivo Exsheathment Assay Of Infective L3 Haemonchus Contortus Larvae In Fistualated Sheep, Holly N. Williams, Katherine Petersson, Carly Barone
Senior Honors Projects
Purpose: Gastrointestinal nematodes (GIN) hinder the sustainable production of small ruminants on pasture and parasite resistance to chemical dewormers is becoming a growing concern. Condensed tannin containing legume forages are being tested to evaluate their anti-parasitic properties and potential contribution to an overall parasite control program for small ruminants such as sheep and goats. One of the most pathogenic GIN of small ruminants is Haemonchus contortus. The final step to full infectivity of H. contortus third stage larvae (L3) is exsheathment in the rumen. The objective of this study was to establish an in-vivo exsheathment assay in fistulated sheep as ...
Relationship Between Heat-Labile Enterotoxin Secretion Capacity And Virulence In Wild Type Porcine-Origin Enterotoxigenic Escherichia Coli Strains, 2015 University of Nebraska-Lincoln
Relationship Between Heat-Labile Enterotoxin Secretion Capacity And Virulence In Wild Type Porcine-Origin Enterotoxigenic Escherichia Coli Strains, Prageeth Wijemanne, Jun Xing, Emil M. Berberov, David B. Marx, David H. Francis, Rodney A. Moxley
Papers in Veterinary and Biomedical Science
Heat-labile enterotoxin (LT) is an important virulence factor secreted by some strains of enterotoxigenic Escherichia coli (ETEC). The prototypic human-origin strain H10407 secretes LT via a type II secretion system(T2SS). We sought to determine the relationship between the capacity to secrete LT and virulence in porcine-origin wild type (WT) ETEC strains. Sixteen WT ETEC strains isolated from cases of severe diarrheal disease were analyzed by GM1ganglioside enzyme- linked immunosorbent assay tomeasure LT concentrations in culture supernatants. All strains had detectable LT in supernatants by 2 h of culture and 1 strain, which was particularly virulent in gnotobiotic piglets (3030-2 ...

With interest we read the paper by Juste et al 1 proposing the amount of zymogen-granule membrane glycoprotein 2 (GP2) on the surface of intestinal bacteria as a Crohn's disease (CD) marker. Indeed, a decreased GP2 level was found on microbes in patients with CD as compared to those of healthy controls. GP2 is a homologue to the urinary Tamm–Horsefall protein demonstrating an antimicrobial function by binding type 1-fimbriated uropathogenic Escherichia coli (UPEC). Likewise, GP2 seems to interact with intestinal bacteria as a specific receptor of bacterial type-1 fimbriae (FimH) on intestinal microfold cells that are partaking in ...

Sarcocystis neurona is a member of the coccidia, a clade of single-celled parasites of medical and veterinary importance including Eimeria, Sarcocystis, Neospora, and Toxoplasma. Unlike Eimeria, a single-host enteric pathogen, Sarcocystis, Neospora, and Toxoplasma are two-host parasites that infect and produce infectious tissue cysts in a wide range of intermediate hosts. As a genus, Sarcocystis is one of the most successful protozoan parasites; all vertebrates, including birds, reptiles, fish, and mammals are hosts to at least one Sarcocystis species. Here we sequenced Sarcocystis neurona, the causal agent of fatal equine protozoal myeloencephalitis. The S. neurona genome is 127 Mbp, more ...
Ectoparasitism Shortens The Breeding Season In A Colonial Bird, 2015 Department of Biological Sciences, University of Tulsa
Ectoparasitism Shortens The Breeding Season In A Colonial Bird, Charles R. Brown, Mary Bomberger Brown
Papers in Natural Resources
When blood-feeding parasites increase seasonally, their deleterious effects may prevent some host species, especially those living in large groups where parasites are numerous, from reproducing later in the summer. Yet the role of parasites in regulating the length of a host’s breeding season—and thus the host’s opportunity for multiple brooding—has not been systematically investigated. The highly colonial cliff swallow (Petrochelidon pyrrhonota), a temperate-latitude migratory songbird in the western Great Plains, USA, typically has a relatively short (eight to nine week) breeding season, with birds rarely nesting late in the summer. Colonies at which ectoparasitic swallow bugs ...

Efficacy Of Intravenous Administration Of Combined Acid Suppressants In Healthy Dogs, 2015 University of Tennessee, Knoxville
Efficacy Of Intravenous Administration Of Combined Acid Suppressants In Healthy Dogs, M Katherine Tolbert, Adesola Odunayo, R S. Howell, E E. Peters, Ann Reed
M Katherine Tolbert DVM, PhD, DACVIM
Background Short-term intravenous co-administration of famotidine and pantoprazole is used by some veterinarians to treat gastrointestinal bleeding in critically ill dogs. However, clinical studies have not evaluated the efficacy of combination acid suppressant treatment in dogs.
Hypothesis/Objectives To compare the effect of intravenous co-administration of famotidine and pantoprazole to monotherapy with pantoprazole on intragastric pH in dogs. We hypothesized that single agent pantoprazole would be more effective than combination with famotidine.
Animals Twelve healthy adult colony dogs.
Methods Randomized, 2-way crossover design. All dogs received placebo (0.9% saline) for 24 hours followed by 1.0 mg/kg IV ...
Maintenance Energy Requirements Of Odor Detection, Explosive Detection And Human Detection Working Dogs, 2015 University of Tennessee - Knoxville
Maintenance Energy Requirements Of Odor Detection, Explosive Detection And Human Detection Working Dogs, Rebecca A. Mullis, Angela L. Witzel, Joshua Price
Angela L Witzel (Lusby) DVM, PhD, DACVN
Despite their important role in security, little is known about the energy requirements of working dogs such as odor, explosive and human detection dogs. Previous researchers have evaluated the energy requirements of individual canine breeds as well as dogs in exercise roles such as sprint racing. This study is the first to evaluate the energy requirements of working dogs trained in odor, explosive and human detection. This retrospective study evaluated twenty adult dogs who maintained consistent body weights over a six month period. During this time, the average energy consumption was [Formula: see text] or two times the calculated resting ...
Repeated Stressors In Adulthood Increase The Rate Of Biological Ageing, 2015 Virginia Polytechnic Institute and State University
Repeated Stressors In Adulthood Increase The Rate Of Biological Ageing, James S. Adelman, Michaela Hau, Mark F. Haussmann, Timothy J. Greives, Christa Matlack, David Costantini, Michael Quetting, Ana C. Miranda, Jesko Partecke
James S. Adelman
Individuals of the same age can differ substantially in the degree to which they have accumulated tissue damage, akin to bodily wear and tear, from past experiences. This accumulated tissue damage reflects the individual’s biological age and may better predict physiological and behavioural performance than the individual‘s chronological age. However, at present it remains unclear how to reliably assess biological age in individual wild vertebrates. We exposed hand-raised adult Eurasian blackbirds (Turdus merula) to a combination of repeated immune and disturbance stressors for over one year to determine the effects of chronic stress on potential biomarkers of biological ...
Methods For Inactivating Pedv In Hog Trailers, 2015 Iowa State University
Methods For Inactivating Pedv In Hog Trailers, Paul R. Thomas, Alejandro Ramierez, Jianqiang Zhang, Joshua S. Ellingson, Jacqueline N. Myers
Animal Industry Report
Porcine epidemic diarrhea (PED) was first described in England in 1971 in growing pigs and the causative agent, porcine epidemic diarrhea virus (PEDV), was identified in 1978. The virus spread to the rest of Europe where it caused outbreaks of diarrhea and significant losses throughout the 1970s and 1980s. PEDV is considered endemic to Europe today, but does not cause widespread significant disease. In parts of Asia outbreaks were recognized first in 1982 and have continued to occur since. In May of 2013 PEDV was identified in swine for the first time in the United States. The virus has caused ...
A Comparison Of The Genetic Factors Influencing Host Response To Infection With One Of Two Isolates Of Porcine Reproductive And Respiratory Syndrome Virus, Andrew S. Hess, Nicholas Boddicker, Bob Rowland, Joan Lunney, Graham Plastow, Jack C. M. Dekkers
Animal Industry Report
Host genetic differences in viral load (VL) and weight gain (WG) during porcine reproductive and respiratory syndrome virus (PRRSV) challenge were assessed for thirteen trials of ~200 commercial crossbred piglets each, from several different commercial suppliers. Piglets were experimentally infected with PRRSV isolates NVSL-97-7895 (NVSL) or KS-2006-72109 (KS06). VL and WG were moderately heritable and were antagonistically related for both virus isolates. The genetic correlation of host response to NVSL with host response to KS06 was high for both VL and WG. Consistent with previous findings, animals that were heterozygous (AB) for the WUR10000125 (WUR) marker on Chromosome 4 (SSC4 ...
Survey-Based Examination Of Demographics, Potential Causes And Treatments Of Aberrant Behavior Syndrome(Berserk Male Syndrome) In Camelids, Stephen R. Ball, Katherine Way, Jennifer A. Schleining, Suzanne T. Millman
Animal Industry Report
The objective of this study was to examine potential signs, causal factors and treatment interventions for camelids displaying Aberrant Behavior Syndrome (ABS), also known as Berserk Male Syndrome. A survey was developed for camelid owners and veterinarians with camelid experience using Survey Monkey software. Respondents were asked to describe the behaviors associated with the most recent case of ABS they were involved with, information about the animal displaying ABS, and evaluation of the efficacy of treatment interventions used. The majority of respondents identified a general demographic of an intact male camelid raised by its biological mother with daily or weekly ...
Accuracies Of Genomic Prediction Of Traits Associated With Lactation And Reproduction In Yorkshire And Landrace Sows, Dinesh M. Thekkoot, Bob Kemp, Max F. Rothschild, Graham Plastow, Jack C. M. Dekkers
Animal Industry Report
Genomic prediction involves statistical methods to estimate the genetic merit of selection candidates based on genetic markers spaced across the genome. The benefit of genomic prediction depends on the accuracies with which we can predict the genomic estimated breeding values (GEBV) of selection candidates based on their marker genotypes. The objective of this study was to estimate the accuracies of GEBV for traits associated with lactation and reproduction in Yorkshire and Landrace sows. Across both breeds, genomic predictions had greater accuracy than pedigree-based predictions. This result suggests that accuracy of selection can be improved by genomic prediction and, thereby, increase ...
Accuracy Of Genomic Prediction For Prrs Antibody Response, 2015 Iowa State University
Accuracy Of Genomic Prediction For Prrs Antibody Response, Nick V. L. Serão, Bob Kemp, Benny Mote, Philip Willson, John Harding, Steve Bishop, Graham Plastow, Jack C. M. Dekkers
Animal Industry Report
The accuracy of genomic prediction for antibody response to Porcine Reproductive and Respiratory Syndrome (PRRS), measured as S/P ratio, was evaluated using two independent datasets of Landrace x Large White females. Results demonstrate that antibody response during a PRRS outbreak can be predicted with high accuracy using genetic markers in two regions on chromosome 7. One of these regions includes the Major Histocompatibility Complex. The high accuracy for this region indicates that marker effects are consistent across Landrace x Large White populations.
Effect Of Wur Genotype And Prrs Vaccination On Pigs Co-Infected With Prrs And Pcv2b, 2015 Iowa State University
Effect Of Wur Genotype And Prrs Vaccination On Pigs Co-Infected With Prrs And Pcv2b, Jenelle R. Dunkelberger, Nick V. L. Serão, Maureen Kerrigan, Joan Lunney, Bob Rowland, Jack C. M. Dekkers
Animal Industry Report
Average daily gain (ADG) and viral load (VL) were evaluated for pigs co-infected with porcine reproductive and respiratory syndrome (PRRS) virus (PRRSV) and porcine circovirus type 2b (PCV2b). Pigs were pre-selected for WUR genotype (a marker on chromosome 4 associated with weight gain and VL under PRRSV-challenge), half were vaccinated for PRRS, and half were not. Results indicate that vaccination for PRRS resulted in slower growth prior to co-infection and that the AB WUR genotype was associated with faster growth prior to co-infection, lower PRRS VL, and lower PCV2b VL in vaccinated pigs.

Kisspeptin receptor (KISS1R) agonists with increased half-life and similar efficacy to kisspeptin in vitro may provide beneficial applications in breeding management of many species. However, many of these agonists have not been tested in vivo. These studies were designed to test and compare the effects of a KISS1R agonist (FTM080) and kisspeptin on luteinizing hormone (LH) in vivo. In experiment 1 (pilot study), sheep were treated with FTM080 (500 pmol/kg BW) or sterile water (VEH) intravenosuly. Blood was collected every 15 min before (1 hr) and after (1 hr) treatment. In experiment 2, sheep were treated with KP-10 (human ...
