Maxwell H. Gluck Equine Research Center Faculty Publications

All around the world, intestinal helminths constitute one of the most prevalent life-long occurring infections and re-infections affecting all horse age groups. A range of parasite species among strongyles, ascarids, and tapeworms is known to have the potential to cause colic in horses. However, there is a lack of current scientific evidence on the actual relevance of helminth infection levels in the context of colic in horses kept during prevailing epidemiological conditions. Thus, a prospective case-control study on the occurrence of intestinal helminths in a total of 620 mainly adult equine clinic patients was conducted to investigate the association between …

In this study, we investigated the use of recombinant antigens thioredoxin peroxidase-1 (rSjTPx-1) and tandem repeat rSj1TR in evaluating the antibody positivity rates of Schistosoma japonicum infection among water buffaloes from four endemic areas in the Philippines, two municipalities with high endemicity (Calatrava, Negros Occidental and Catarman, Northern Samar) and two municipalities nearing elimination with no cases of human schistosomiasis (Talibon and Trinidad, Bohol). These recombinant antigen ELISA assays were compared with other diagnostic tests including SEA-ELISA, FECT, and fecal-based PCR. Results showed that rSj1TR-ELISA has the highest agreement with PCR in all study areas. Furthermore, significant positivity rates among …

Meta-Analysis Of Cyathostomin Species-Specific Prevalence And Relative Abundance In Domestic Horses From 1975-2020: Emphasis On Geographical Region And Specimen Collection Method, Jennifer L. Bellaw, Martin K. Nielsen

Maxwell H. Gluck Equine Research Center Faculty Publications

BACKGROUND: Cyathostomins infect virtually all horses, and concomitant infections with 10 or more species per horse is standard. Species-specific knowledge is limited, despite potential species bias in development of disease and anthelmintic resistance. This is the first meta-analysis to examine effects of geographical region and cyathostomin collection method on reported composition of cyathostomin communities.

METHODS: Thirty-seven articles published in English in 1975 or later, in which adults of individual species were systematically enumerated, were included. Seven regions; North America, South America, eastern Europe, western Europe, northern Europe, southern Africa, and Oceania, and three cyathostomin collection methods; (i) standard necropsy recovery …

Prevalence Of Taeniid Eggs In The Faeces Of Domesticated And Free-Roaming Dogs In Basrah, Iraq, And The Knowledge Of Dog Owners On Cystic Echinococcosis, Mohanad Faris Abdulhameed, Ian Robertson, Suzan Abd Al-Jabbar Al-Azizz, Ihab Habib

Karbala International Journal of Modern Science

The larval stages (metacestodes) of some taeniids of carnivores, particularly Echinococcus spp., can result in severe disease for humans and livestock. The prevalence of taeniid eggs by direct examination of faecal smears in 335 free-roaming dogs (FRD) and owned domesticated dogs in Basrah Province was 10.1% (95% CI 7.1, 13.9). A structured questionnaire was administered to 86 dog owners to investigate the influence of socio-demographic factors and management and husbandry practices on their knowledge of cystic echinococcosis (CE). The results of a multivariable logistic regression analysis revealed that dog owners who fed offal had less knowledge of CE (OR=0.17, 95% …

Tools, Techniques And Teamwork: Transferring New Technologies For Wildlife Management, Conservation And Economic Development, John Eisemann, Gail Keirn

United States Department of Agriculture Wildlife Services: Staff Publications

Did you ever wonder who invented radio telemetry? Or breakaway snares? What about the bird repellent methyl anthranilate or the livestock protection collar? These and many other tools used in wildlife damage management resulted from creative thinking by biologists, technicians, researchers and managers working to solve complex wildlife issues. Over the past 90 years, these “aha moments” within the U.S. Department of Agriculture’s Wildlife Services program have ranged from developing novel scare devices, traps and vaccines to exploiting an animal’s visual capabilities to stop unwanted behaviors. Once discovered, these unique ideas may lead to practical, feasible and cost-effective wildlife damage …

Instability Of Glucocorticoid Metabolites In Coyote Scats: Implications For Field Sampling, Erika T. Stevenson, Eric M. Gese, Lorin A. Neuman-Lee, Susannah S. French

United States Department of Agriculture Wildlife Services: Staff Publications

Studying physiologic stress responses can assist in understanding the welfare of animals. One method of measuring the physiologic stress response is evaluating concentrations of glucocorticoid metabolites in feces. Previously, using an adrenocorticotropic hormone challenge, we found fecal glucocorticoid metabolite levels were a reliable indicator of physiologic stress response in coyotes (Canis latrans). We determine whether glucocorticoid metabolite concentrations remain stable when collecting feces over a 2-week period, a timeframe commonly used in scat surveys for wild canids. We collected feces from 6 captive coyotes maintained at the U.S. Department of Agriculture, Wildlife Services, National Wildlife Research Center, Predator …

Importation Of Macrocyclic Lactone Resistant Cyathostomins On A Us Thoroughbred Farm, Martin K. Nielsen, M. Banahan, R. M. Kaplan

Maxwell H. Gluck Equine Research Center Faculty Publications

Anthelmintic resistance in equine cyathostomins is both widespread and highly prevalent in the benzimidazole and tetrahydropyrimidine classes; however, reports of resistance to macrocyclic lactone (ML) drugs are sparse and sporadic. This study reports a case of clear ML resistance in a group of Thoroughbred yearlings imported from Ireland to the US in 2019. Fecal egg count reduction (FECR) following ivermectin administered in February 2020 demonstrated 100% reduction in the US bred yearlings, but 93.5%, 70.5%, and 74.5% reduction in three groups of the imported yearlings. The two former groups were then retreated with ivermectin, yielding FECRs of 33.8% and 23.5%, …

Evaluating Red Wolf Scat To Deter Coyote Access To Urban Pastureland, Meghan M. Louis, Samuel M. Tucker, Michael K. Stoskopf, Suzanne Kennedy-Stoskopf

Human–Wildlife Interactions

Depredation of domestic livestock by wildlife is a leading source of human–wildlife conflict, often requiring intervention at the local level. Historically, these interventions have resulted in the use of lethal methods to remove the offending animal. In response to increased public opposition to lethal control methods, wildlife managers have sought to identify effective nonlethal biological options to mitigate wildlife depredations. In 2018, we tested the concept of a biological deterrent using red wolf (Canis rufus) scat that had historically been spread along fence lines to prevent depredation of lambs (Ovis aries) and kid goats (Capra …

Molecular And Biological Epidemiology Of Mosquito Vecors For Canine Heartworm Infection In The Cumberland Gap Region, Charles T. Faulkner, Michelle Norden

Faculty Other Scholarly Content

Canine heartworm (Dirofilaria immitis), is a nematode parasite that infects canines, both wild and domestic and other vertebrate hosts like ferrets, otters, and cats worldwide. The disease, dirofilariasis, can be fatal in advanced stages if untreated and is recognized as a significant concern in veterinary medicine. Canine heartworm has been reported in 49 states of the United States (U.S.) and is considered enzootic. The nematode lifecycle is dependent upon canines infected with adult worms that produce microfilaria, the vermiform embryonic stage, that circulate in the peripheral blood of the host and the mosquito vectors that ingest them taking …

Biology Faculty Publications

Background

Schistosoma japonicum, which inhabits the mesenteric vein of the mammalian hosts for about 20 to 30 years, is subjected to the oxidative stresses from the host defense mechanism during their intra-mammalian stages. To counteract this host immune attack, the parasite utilizes their antioxidant system for survival inside the host. Peroxiredoxins (Prxs), thiol-specific antioxidant proteins, play an essential role for protecting the parasite against oxidative stress by reducing hydrogen peroxide to water. Only three types of 2-Cys Prxs have been previously characterized in S. japonicum whereas a fourth Prx has been identified for Schistosoma mansoni as Prx-4. A sequence …

Correction Of Diaphragmatic Hernia Using The Transverse Colon In A Dog, Dongwook Kim, Gonhyung Kim

The Thai Journal of Veterinary Medicine

A 3-year-old female Golden Retriever was referred with weakness, tachypnea and dyspnea. An incomplete diaphragmatic silhouette, gas-filled small intestine and pleural effusion in the thoracic cavitywere revealed in radiographs, implying a diaphragmatic hernia. After laparotomy, the abdominalstructureswere gently retrieved into the abdomen and a defect of 2×7 cm2was found. The transverse colonwas used as an autologous tissue flap for the repair of the defect. There were no complications identified for 2 years after surgery. Thus, patching with the transverse colon can be considered as an alternative for treating a defect in patients with a diaphragmatic hernia.

Chondroprotective Efficacy Of Undenatured Collagen Type Ii On Canine Osteoarthritis Secondary To Medial Patellar Luxation, Susolos Kunsuwannachai, Kumpanart Soontornvipart

The Thai Journal of Veterinary Medicine

Osteoarthritis (OA) is found secondary to medial patellar luxation (MPL) which is one of the most common diseases in small-breed dogs. Management of the disease is surgical correction or medical treatment. In patients who are unable to do the surgical correction, non-steroidal anti-inflammatory drugs (NSAIDs) remain the drugs of choice for OA therapy. Nowadays nutraceuticals have become more popular since there are no side effects when given for along period. The purpose of this study was to evaluate the clinical chondroprotective effects of undenatured collagen type-II (UCII) on osteoarthritis secondary to canine medial patellar luxation. Nine small-breed dogs (thirteen stifle …
