ABSTRACT

The present study aimed to investigate the status of helminth infections in wild boars in the Bursa province of Turkey. For this purpose, during 2007-2008, 27 wild boars were necropsied and examined for helminths. Individual samples of tongue and diaphragm from 27 necropsied wild boars and an additional 22 tongue and diaphragm samples provided by hunters were examined by trichinoscopy and artificial digestion for Trichinella spp. larvae. Twenty animals (74%) were identified as being infected with at least one helminth species. Twelve species of helminths were detected, with the following prevalence rates: Metastrongylus apri (59%), Metastrongylus salmi (52%), Metastrongylus pudendotectus (52%), Dicrocoelium dendriticum (33%), Globocephalus urosubulatus (22%), Macracanthorhynchus hirudinaceus (19%), Gongylonema pulchrum (11%), Physocephalus sexalatus (7%), Trichuris suis (7%), Ascarops strongylina (4%), Hyostrongylus rubidus (4%) and Taenia hydatigena larvae (4%). Generally, lungworms were the predominant helminths. The highest mean abundance was observed for M. pudendotectus, and the lowest was determined for T. hydatigena larvae. Significant differences in the prevalence and intensity were found for D. dendriticum with respect to host age and sex, respectively. The mean intensity of M. pudendotectus was significantly influenced by the sex and age of the wild boars. This study is the first report describing the presence of M. salmi, M. pudendotectus, D. dendriticum, G. urosubulatus, M. hirudinaceus, P. sexalatus, A. strongylina and H. rubidus in wild boars in Turkey. All analysed muscle samples were negative for Trichinella spp. larvae.

ABSTRACT

The seasonal patterns of strongyle infections in untreated, weaned lambs were determined on four governmental farms during a grazing season. In three farms, the infection level (predominantly Teladorsagia spp. and Trichostrongylus spp.) measured by egg counts or worm burdens remained low throughout the study; higher egg counts mainly caused by Haemonchus contortus were transiently recorded on the fourth farm. Significant body weight gains were observed in all groups, but they varied between farms irrespective of the level of strongyle infections, suggesting that the economic effectiveness of anthelmintic treatments of weaned lambs is doubtful under the extensive grazing conditions and the hot, dry climate in the region. In the second part of the study, faecal egg count reduction tests were performed for albendazole, thiabendazole, tetramisole and ivermectin on 12 sheep and goat farms to provide first information on anthelmintic resistance in trichostrongyles of small ruminants in Turkey. There was no hint of benzimidazole resistance, and unequivocal evidence of ivermectin resistance was missing. In contrast, tetramisole resistance was detected on one sheep farm.

ABSTRACT

The prevalence of Toxocara vitulorum in cattle around Bursa, Turkey, was surveyed by faecal examination of eggs. The average infection rate among 11 towns was 5.1% in calves younger than 6-months-old, and 2.2% in all ages of animals. T. vitulorum was found to be prevalent in two different areas of Bursa. Third stage larvae were found in one milk sample and therefore galactogenic transmission was suggested. Experimental incubation of eggs showed that the optimum temperature for development was 20 to 30 degrees C and eggs could survive under low temperature, indicating that grazing in the contaminated pasture may accelerate the transmission of eggs to cows. Mode of farming, therefore, affects the infection rate of T. vitulorum and may explain the difference in the rate between the two areas.

ABSTRACT

Effects of artemether were examined on Schistosoma japonicum in mice. When the drug was given at a daily dosage of 200 mg/kg for 4 successive days from 46 days post-infection, a significant reduction in worm recovery was observed. A significant reduction in size of worms from the medicated mice was also seen compared with that from non-medicated controls.

ABSTRACT

Mebendazole was given to mice infected with Angiostrongylus costaricensis at a single dose of 5 mg/kg at 6, 11, 16 or 21 days post-infection (p.i.) and in five successive doses at 5 mg/kg daily at 6, 11 or 16 days p.i. The effects were comparatively assessed by examining various parameters in host mice and worms. As a whole, the effects of mebendazole were caused more conspicuously by five successive treatments than by a single treatment. In both treatment modalities, the effects were more remarkable in earlier treatments, and nearly complete effects were caused by five successive treatments before 15 days p.i. These results suggest that the inhibition of egg formation and/or oviposition will inhibit the pathological changes caused in the disease by A. costaricensis, especially before the onset of the changes.
