A quantitative analysis of attitudes and behaviours concerning sustainable parasite control practices from Scottish sheep farmers
Publication date: Available online 14 February 2017 Source:Preventive Veterinary Medicine Author(s): Corin Jack, Emily Hotchkiss, Neil D. Sargison, Luiza Toma, Catherine Milne, David. J. Bartley Nematode control in sheep, by strategic use of anthelmintics, is threatened by the emergence of roundworms populations that are resistant to one or more of the currently available drugs. In response to growing concerns of Anthelmintic Resistance (AR) development in UK sheep flocks, the Sustainable Control of Parasites in Sheep (SCOPS) initiative was set up in 2003 in order to promote practical guidelines for producers and advisors...

Cat Ownership Not Linked to Increased Risk of Psychosis
Does having a cat increase the risk of psychosis in humans?House cats are often carriers of the parasiteToxoplasmosis gondii. Epidemiological and animal studies at least suggest an increased risk for schizophrenia followingin utero or early childhood exposure to the parasite.There may be such a connection, but mere ownership of a cat during pregnancy or in early childhood does not increase the risk of psychotic events when children reach age 13 or 18, wrote Francesca Solmi, Ph.D., a postdoctoral research associate in psychiatric epidemiology at University College London, in a study published yesterday inPsychological Medic...

A rapidly progressive hydatid disease imitating metastatic malignancy: An unusual multi-organ presentation. Report of a case and review of literature
Publication date: Available online 24 February 2017 Source:Respiratory Medicine Case Reports Author(s): Qays Ahmed Hassan Al-timimy Hydatid disease is still a major health and socio-economic problem in endemic regions. It is the most frequent parasitic infection that commonly affects the liver and rarely involves multiple organs. Herein, I report an extraordinary case of multi-organ hydatid disease that presented with rapidly progressive disseminated nature that mimic metastatic malignancy highlighting the interest of keeping a high level of clinical suspicion of this diagnosis especially in endemic regions.

Risk factors for the presence of Deformed wing virus and Acute bee paralysis virus under temperate and subtropical climate in Argentinian bee colonies
The objective of the present study was to evaluate the presence of seven virus species (Deformed wing virus –DWV-, Acute bee paralysis virus –ABPV-, Chronic bee paralysis virus –CBPV-, Black queen cell virus –BQCV-, Kashmir bee virus –KBV-, Israeli acute bee paralysis virus –IAPV-, and Sacbrood bee virus –SBV), as well as the prevalence of Nosema sp. and Varroa destructor, and their possible associated factors, under temperate and subtropical climate conditions in Argentinean colonies. A total of 385 colonies distributed in five Argentinean eco-regions were examined after honey harvest. The final multivariabl...

‘Snorkel’ lice barrier technology reduced two co-occurring parasites, the salmon louse (Lepeophtheirus salmonis) and the amoebic gill disease causing agent (Neoparamoeba perurans), in commercial salmon sea-cages
Publication date: Available online 10 March 2017 Source:Preventive Veterinary Medicine Author(s): D.W. Wright, L.H. Stien, T. Dempster, T. Vågseth, V. Nola, J.-E. Fosseidengen, F. Oppedal Diverse chemical-free parasite controls are gaining status in Atlantic salmon sea-cage farming. Yet, the intricacies of their use at commercial scale, including effects on co-occurring parasites, are seldom reported. A new salmon lice prevention method involves installing a deep net roof and ‘snorkel’ lice barrier in cages to shelter salmon from free-living infective larvae which concentrate at shallow depths, and allows salmon to j...

Raccoon dog is a more acute risk than raccoon as vector for local parasites
(University of Veterinary Medicine -- Vienna) The increasing abundance of raccoons and raccoon dogs made them of interest to parasitologists as potential hosts for diseases. Researchers from Vetmeduni Vienna now analyzed samples in Austria. The raccoon dog was shown to serve as an additional host for local parasites. It represents a risk as a host of zoonotic parasites, such as the fox tapeworm or trichina worms. The raccoons sampled, as they originated from fur farms, were still largely pathogen-free.

Preliminary study on investigation of zoonotic visceral leishmaniasis in endemic foci of Ethiopia by detecting Leishmania infections in rodents
Conclusions Leishmania donovani might circulate among different species of rodents in kala-azar endemic lowlands and valleys of Ethiopia by Phlebotomus orientalis and Phlebotomus martini. Detailed studies to substantiate the preliminary data on the possible role of these rodents are urgently needed.

Anthelmintic activity of Moringa oleifera seed aqueous and ethanolic extracts against Haemonchus contortus eggs and third stage larvae
This study evaluated the anthelmintic potential of Moringa oleifera seed ethanolic and aqueous extracts against H. contortus eggs and infective stage larvae (L3s). The efficacy of five extract concentrations (0.95, 1.95, 3.9, 7.8, and 15.6mg/mL) were tested through egg hatch assay and larval motility test. Phytochemical tests were conducted to detect the different plant secondary metabolites in the extracts. In the ovicidal assay, the ethanolic and aqueous extracts showed 95.89% and 81.72% egg hatch inhibition at 15.6mg/mL, respectively. The ovicidal activity of 15.6mg/mL ethanolic extract was comparable with that of alben...

Hemoperitoneum secondary to cecocolic dilation in a pregnant mare
In this report, a pregnant mare was diagnosed with hemoperitoneum secondary to cecocolic dilatation, due to corn ingestion. The protocol for clinical treatment and tests varies in similar reported cases. Due to this, our report discusses the outcome of a clinical case and suggests a medical protocol -based on evidence – for treatment in a pregnant mare. The treatment was aimed to stop the bleeding, while normalize or maintain a stable blood pressure and provide supportive therapy. The mare presented colic pains due to fermentation of the corn, which were solved in few hours. The final abdominal ultrasonogram showed intra...

Attitudes towards worm egg counts and targeted selective treatment against equine cyathostomins
Publication date: Available online 6 May 2017 Source:Preventive Veterinary Medicine Author(s): H. Rose Vineer, F. Vande Velde, K. Bull, E. Claerebout, E.R. Morgan Gastrointestinal nematodes present a major threat to the health and welfare of equids worldwide. Anthelmintic resistance (AR) is increasingly reported and challenges effective control in horses and ponies in many regions. The use of faecal worm egg counts (FECs) to support targeted treatment (FEC-TT) and targeted selective treatment (FEC-TST) has been promoted as an effective deworming strategy that may prolong the useful life of anthelmintics and reduce the cos...
