During 2011, faeces from 235 owned domestic cats from a rural area in western Hungary were examined using standard coproscopical techniques. The overall prevalence of cats with endoparasites was 39.6% (95% CI 33.3-46.1). The most frequently identified faecal forms were those of ascarids (Toxocara, 17.4%; Toxascaris 7.2%), followed by those of(More)
One hundred eighty-one dogs and 26 short-hair cats from suburban areas around Tirana, Albania were examined for ectoparasite infestation. The dogs were examined on several occasions from 2005 through 2009 representing three seasons: winter (December–February), spring (March–May), and summer (June–August); the cats were examined in late autumn (November).

Durch Arthropoden übertragene Infektionen haben in der jüngeren Vergangenheit zunehmend an Bedeutung gewonnen, auch bedingt durch vermehrte Reisen in, beziehungsweise Importe von Hunden aus Regionen, in denen die Erreger endemisch sind. Während die epidemiologische Situation im westlichen Mittelmeerraum gut dokumentiert ist, sind aus Osteuropa und dem(More)
From 2004 to 2009, the digestive tracts of 111 dogs from suburban areas around Tirana, Albania, were examined for intestinal helminths. In addition, rectal faecal samples of all dogs were examined for protozoan infections and 48 faecal samples from dogs >6 months of age were processed with the Baermann technique to test for the excretion of lungworm larvae.(More)
Im Kot von Katzen aus dem Großraum Tirana wurden Larven nachgewiesen, die für eine Infektion mit dem Lungenwurm Aelurostrongylus abstrusus sprachen. Dieser Befund konnte durch die Sektion von 18 Katzen bestätigt werden, von denen 9 einen Befall der Lungen mit adulten A. abstrusus (Railliet, 1898) (Prävalenz 50 %; 1–11 Würmer) aufwiesen. Neben A. abstrusus(More)
A randomised block design study was conducted to evaluate the effects of mange on cattle. Twenty-four Simmentaler Fleckvieh bulls were formed into eight replicates of three bulls based on Day -56 body weight (288-414 kg). Within replicates bulls were randomly allocated to groups G1: uninfested control, G2: infested control or G3: infested, treated with(More)
Four trials, using 48 European breed cattle, were conducted to evaluate the efficacy of abamectin against the louse species Linognathus vituli, Haematopinus eurysternus and Damalinia bovis and against the mange mites Sarcoptes scabiei var bovis and Psoroptes ovis. Animals were allocated by restricted randomisation based on parasite counts to treatment with(More)
Two trials were conducted to confirm the efficacy of ivermectin paste against endoparasites of horses. In these trials, 20 ponies were treated with ivermectin oral paste at 200 mcg x kg body weight once on Day 0, and 20 ponies served as unmedicated controls. The animals carried naturally acquired parasite infections as confirmed by pretrial fecal(More)
A randomized block design study was conducted to confirm the efficacy of topical eprinomectin against naturally acquired Chorioptes bovis mite infestations. Twelve adult Simmentaler Fleckvieh cattle were formed into six replicates of two animals based on pretreatment mite counts. Within replicates, animals were randomly allocated to untreated controls or(More)
