Turkish Journal of Veterinary & Animal Sciences

The Mycobacterium avium complex (MAC) causes infections and diseases in humans, birds, livestock, and wildlife, among others. In dogs, MAC infection is not frequent; however, due to its potential zoonotic characteristics, mainly in immunocompromised patients, the study of MAC epidemiology is necessary. The aim of this work was to perform a study to detect the presence of antibodies against MAC in serum samples of 53 hunting dogs in the Idanha-a-Nova municipality of East-Central Portugal. A total of 23 dogs were seropositive by commercial ELISA test (43.4%, 95% CI: 30.1%-56.7%). Factors such as age, breed, and sex were not significant. The …

Comparison Of The Efficiency Of Concentrated Soluble Recombinant Phospholipase D And Natural Phospholipase D Enzymes, Asli Sakmanoğlu, Osman Ergani̇ş

Turkish Journal of Veterinary & Animal Sciences

Phospholipase D (PLD) is a major virulence determinant of Corynebacterium pseudotuberculosis. Various studies have focused on the expression of recombinant PLD (rPLD) enzyme in different Escherichia coli strains, but generally a high yield of insoluble protein was reported. The aims of this study were to express soluble rPLD by different methods in E. coli. The rPLD and natural PLD (dPLD) enzymes were concentrated using an ultramembrane cassette system after the efficiencies of these concentrated enzymes were compared. The rPLD enzyme was expressed in One Shot®BL21(DE3) E. coli when induced by IPTG in TY medium. Soluble dPLD and rPLD enzyme hemolytic …

The Effect Of Feeding Rhizopus Oligosporus On Growth Performance, Nutrient Digestibility, Blood Profile, Fecal Microbiota, And Fecal Score In Weanling Pigs, Jae Hong Park, Hyeok Min Yun, In Ho Kim

Turkish Journal of Veterinary & Animal Sciences

Piglets were allocated to 1 of 3 treatments by body weight and sex, and fed different levels of 0%, 0.15%, and 0.30% of R. oligosporus 1.0 x 106 cfu/g, in a basal diet based on corn-soybean meal for 35 days. Piglets fed diets supplemented with R. oligosporus had higher average daily gain during days 15-35 and 1-35 (quadratic, P < 0.05). Feed conversion ratio during 1-35 days showed a significant improvement, as dietary R. oligosporus supplementation increased from 0.15% to 0.30% (linear, P < 0.05). Apparent total tract digestibility (ATTD) of crude protein (CP) was increased at 2 weeks, as dietary R. oligosporus supplementation increased significantly (linear and quadratic, P < 0.05), and ATTD of dry matter, CP, and energy were linearly increased at 5 weeks (P < 0.05). The serum IgG concentration was significantly increased in the R. oligosporus-fed groups (quadratic, P < 0.05). Fecal Lactobacillus counts were significantly increased quadratically and coliform bacteria counts were decreased linearly, as dietary R. oligosporus supplementation increased (P < 0.05). In conclusion, diets containing R. oligosporus may improve the growth performance, nutrient digestibility, IgG concentration, and intestinal environment in weanling pigs.

Veterinarians Need Support To Break The Silence, Anne Fawcett

Animal Sentience

The question of whether reporting animal abuse should be mandatory for veterinarians is an important one. Veterinarians have dual obligations, both to their animal patients and to their human clients. Mandatory reporting can only be supported in a context in which veterinary professionals are (a) trained to recognise the signs of animal abuse; (b) trained to elicit a history sensitively from clients who may themselves be victims of abuse or supported in doing so; (c) supported by appropriate, responsive authorities; (d) reasonably protected from legal recriminations.

Identification And Characterization Of A Relish-Type Nf-Kb, Dvrelish In Dermacentor Variabilis, The American Dog Tick, Victoria Irene Verhoeve

LSU Doctoral Dissertations

Ticks are important worldwide as vectors of bacteria, viruses, and parasites. Pathogenic and non-pathogenic Spotted fever group (SFG) Rickettsia are maintained and transmitted by ticks with specific hard tick-Rickettsia pairings evident in nature. The pathogenic SFG Rickettsia rickettsii is transmitted by the hard tick Dermacentor variabilis. In response to infection, D. variabilis is known differentially respond to SFG Rickettsia infection. The mechanisms of differential immune induction are currently unknown, and are likely involved in the establishment of specific tick-SFG Rickettsia pairings. It was hypothesized that the level of response by D. variabilis to SFG Rickettsia occurs in a species-specific manner, …

Characterization Of Rickettsial Infection Dynamics Within Dermacentor Variabilis And Amblyomma Maculatum, Emma Kate Harris

LSU Doctoral Dissertations

Spotted fever group (SFG) Rickettsia are primarily associated with their reservoir host and vector, the tick. Rickettsial colonization and maintenance within the arthropod is a key component of vector competence and pathogen transmission to the mammalian host. Contemporary detection of novel tick hosts for rickettsial species, combined with an unprecedented rise in human cases of SFG rickettsiosis, necessitates a deeper understanding of tick/Rickettsia interactions. The hypothesis for this work is that if primary tick/Rickettsia pairings do not exist then rickettsial determinants account for primary vector/pathogen relationships. To this end, Dermacentor variabilis and Amblyomma maculatum ticks were exposed to R. rickettsii, …

Gps Tracking Of Free-Ranging Pigs To Evaluate Ring Strategies For The Control Of Cysticercosis/Taeniasis In Peru, Ian W. Pray, Dallas J. Swanson, Viterbo Ayvar, Claudio Muro, Luz Maria Moyano, Armando E. Gonzalez, Hector H. Garcia, Multiple Additional Authors

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background Taenia solium, a parasitic cestode that affects humans and pigs, is the leading cause of preventable epilepsy in the developing world. T. solium eggs are released into the environment through the stool of humans infected with an adult intestinal tapeworm (a condition called taeniasis), and cause cysticercosis when ingested by pigs or other humans. A control strategy to intervene within high-risk foci in endemic communities has been proposed as an alternative to mass antihelminthic treatment. In this ring strategy, antihelminthic treatment is targeted to humans and pigs residing within a 100 meter radius of a pig heavily-infected with cysticercosis. …

Echinococcus Multilocularis In Foxes And Raccoon Dogs: An Increasing Concern For Baltic Countries, Guna Bagrade, Gunita Deksne, Zanda Ozoliņa, Samantha Jane Howlett, Maria Interisano, Adriano Casulli, Edoardo Pozio

Harold W. Manter Laboratory of Parasitology: Library Materials

Background

In Europe, the life cycle of Echinococcus multilocularis is predominantly sylvatic, involving red foxes (Vulpes vulpes) as the main definitive hosts and rodents such as muskrats and arvicolids as intermediate hosts. The parasite is the etiological agent of human alveolar echinococcosis, a malignant zoonotic disease caused by the accidental ingestion of eggs shed by definitive hosts in their feces. The aims of this study were to investigate the prevalence of E. multilocularis in red foxes and raccoon dogs (Nyctereutes procyonoides) and to study the environmental factors favoring the perpetuation of the parasite in Latvia. …

Autoimmunity In Picornavirus Infections, Chandirasegara Massilamany, Andreas Koenig, Jay Reddy, Sally Huber, Iwona Buskiewicz

School of Veterinary and Biomedical Sciences: Faculty Publications

Enteroviruses are small, non-enveloped, positive-sense singlestrand RNA viruses, and are ubiquitously found throughout the world. These viruses usually cause asymptomatic or mild febrile illnesses, but have a propensity to induce severe diseases including type 1 diabetes and pancreatitis, paralysis and neuroinflammatory disease, myocarditis, or hepatitis. This pathogenicity may result from induction of autoimmunity to organ-specific antigens. While enterovirus-triggered autoimmunity can arise from multiple mechanisms including antigenic mimicry and release of sequestered antigens, the recent demonstration of T cells expressing dual T cell receptors arising as a natural consequence of Theiler’s virus infection is the first demonstration of this autoimmune mechanism.
