Acute phase protein pattern and antibody response in pigs experimentally infected with a moderate dose of Trichinella spiralis, T. britovi, and T. pseudospiralis Vet. Parasitol. (IF 2.157) Pub Date : 2020-10-22 Michał Gondek; Przemysław Knysz; Małgorzata Pomorska-Mól; Monika Ziomek; Justyna Bień-Kalinowska
The aim of the present study was to evaluate the acute-phase protein (APP) response in three groups of pigs experimentally infected with a moderate infective dose, i.e. 1000 muscle larvae (ML) of Trichinella spiralis, 3000 ML of Trichinella britovi, and 2000 ML of Trichinella pseudospiralis. Over a 62-day period of infection, we examined the serum level and kinetics of the haptoglobin (Hp), C-reactive

Recent epidemiologic and clinical importance of Toxoplasma gondii infections in marine mammals: 2009-2020 Vet. Parasitol. (IF 2.157) Pub Date : 2020-10-26 Jitender P. Dubey; Fernando H.A. Murata; Camila K. Cerqueira-Cézar; Oliver C.H. Kwok; Michael E. Grigg
Toxoplasma gondii infections are common in humans and animals worldwide. T. gondii causes mortality in several species of marine mammals, including threatened Southern sea otters (Enhydra lutris) and endangered Hawaiian monk seals (Monachus schauinslandi). Marine mammals are now considered sentinels for environmental exposure to protozoan agents contaminating marine waters, including T. gondii oocysts

Effect of birdsfoot trefoil cultivars on exsheathment of Haemonchus contortus in fistulated sheep Vet. Parasitol. (IF 2.157) Pub Date : 2020-10-13 Karalyn J. Lonngren; Carly D. Barone; Anne M. Zajac; Rebecca N. Brown; Jess D. Reed; Christian G. Krueger; Katherine H. Petersson
Proanthocyanidin (PAC, condensed tannin) containing forages have well-documented anti-parasitic effects against gastrointestinal nematodes (GIN) of small ruminants. Although extensive research has been conducted on the inhibition of exsheathment of the L3 stage of Haemonchus contortus by in vitro exposure to the extracts of PAC containing plants, only one study has previously attempted to replicate

Repeated vaccination against Haemonchus contortus provides continuous protection to young grazing sheep Vet. Parasitol. (IF 2.157) Pub Date : 2020-10-16 Cesar C. Bassetto; Fabiana A. Almeida; George F.J. Newlands; W. David Smith; Alessandro F.T. Amarante
Haemonchus contortus is the most important gastrointestinal nematode in the tropics and subtropics causing huge economic losses to the small ruminant industry. Vaccination is potentially a sustainable approach to control this parasite and the performance of Barbervax® a vaccine containing integral membrane glycoproteins from H. contortus intestinal cells, was evaluated in naturally infected grazing

Interaction between abomasal blood feeder Haemonchus contortus and intestinal mucosal browser Trichostrongylus colubriformis during co-infection in Boer goats Vet. Parasitol. (IF 2.157) Pub Date : 2020-10-15 N. Hayyan Basripuzi; Reuben S.K. Sharma; Z. Norhadila; Z.S. Shahar; M.S. Nor-Dilaila; M.S. Mustapha; V. Kolandaiveloo; K. Ruviniyia; L. Matthews
This study was conducted to investigate potential interactions between the abomasal blood feeder Haemonchus contortus and the intestinal mucosal browser Trichostrongylus colubriformis among deliberately infected Boer goats. Faecal and blood samples were collected twice a week for eight weeks from 25 parasite-naïve goats. Correlation analysis and multiple linear regression models were conducted to explore

Characterization of GASA-1, a new vaccine candidate antigen of Babesia bovis Vet. Parasitol. (IF 2.157) Pub Date : 2020-10-16 Daniela A. Flores; Anabel E. Rodriguez; Mariela L. Tomazic; Susana Torioni de Echaide; Ignacio Echaide; Patricia Zamorano; Cecilia Langellotti; Flabio R. Araujo; Peter Rolls; Leonhard Schnittger; Monica Florin-Christensen
Surface proteins bound to the cell membrane by glycosylphosphatidylinositol (GPI) anchors are considered essential for the survival of pathogenic protozoans. In the case of the tick-transmitted hemoparasite Babesia bovis, the most virulent causative agent of bovine babesiosis, the GPI-anchored proteome was recently unraveled by an in silico approach. In this work, one of the identified proteins, GASA-1

Spatial epidemiology of cystic echinococcosis in livestock from a hyper-endemic region in southern Chile Vet. Parasitol. (IF 2.157) Pub Date : 2020-09-30 Hamilton Hombo; Miguel Oyarzo; Claudia Álvarez; Natalia Cuadros; Felipe Hernández; Michael P. Ward; Gerardo Acosta-Jamett
Cystic echinococcosis (CE) is a parasitic zoonosis, caused by the larval stage of Echinococcus granulosus. This disease has a worldwide distribution and is considered an important zoonosis in Chile, especially in regions where raising livestock dominates. We aimed to describe the spatial distribution and risk factors for CE in cattle and sheep slaughtered in the Aysén Region, Chile between 2015 and

Genetic parameters for production traits, resistance and resilience to Nematode parasites under different worm burden challenges in Corriedale sheep Vet. Parasitol. (IF 2.157) Pub Date : 2020-10-15 Camila Balconi Marques; Virginia Goldberg; Gabriel Ciappesoni
Characterized as the most important gastrointestinal parasite (GIP) in the world, Haemonchus contortus is also the most predominant and pathogenic genus in Uruguay, causing high morbidity and mortality rates in sheep flocks. For approximately 26 years resistance to GIP has been included in the National Genetic Evaluation (NGE) of Corriedale and Merino breeds, using Faecal Egg Count (FEC) as the selection
