background: among the infectious organisms of parasitic origin, gastrointestinal nematodes are very important as they have been reported worldwide. the main aim of the present research study to highlight the annual epidemiological contributing factors associated with the prevalence of gastrointestinal nematodes and their control in sheep. methods: a total 1200 faecal samples (100 per month) wer...

The objective of this study was to investigate an interaction between nematodes and gut Enterobacteriaceae that use benzimidazoles as a carbon source. By addressing this objective, we identified an anthelmintic resistance-like mechanism for gastrointestinal nematodes. We isolated 30 gut bacteria (family Enterobacteriaceae) that subsist on and putatively catabolize benzimidazole-class anthelmint...

Introduction Gastrointestinal nematodes, external parasites, and Fasciola hepatica (liver fluke) can all adversely affect productivity of cattle.(1-5) Previously, little to no work has been done to quantify the effect of treating yearling replacement beef heifers for both gastrointestinal nematodes and bovine liver fluke on weight gain, body condition scores, pregnancy rates, and subsequent wea...

Gastrointestinal nematodes resistant to anthelmintics have been reported in several regions of Brazil, and they may be associated with economic losses for the cattle industry. This study aimed to evaluate the resistance status of gastrointestinal nematodes from naturally infected beef cattle to several commercially available anthelmintics, as well as to test the efficacy of combinations of anth...

present research was for study on parasitic infections of domestic ruminants in golestan province. 234 samples of the gastrointestinal tracts contents, 260 livers, 180 lungs, 350 hearts and muscles, 300 abdominal cavities and 100 eyes for infection to helminthes, 800 blood samples for protozoa and external coats of 700 animals were examined for arthropoda. results showed that 19.74% of sheep ga...

Prevalence of gastrointestinal parasites was studied in 106 heifers imported to Poland from the Netherlands. Prevalence of gastrointestinal nematodes and Eimeria protozoans was determined from coproscopic examinations using Willis-Schlaf flotation. The species composition of coccidia was determined from morphological characters and the time of oocyst sporulation. Fluke liver eggs were detected ...

Helminthiasis or infection with gastrointestinal nematodes such as Haemonchus contortus is a common problem in grazing animals which can lead to poor animal performance and economic loss to the livestock industry (Waller & Thamsborg, 2004). In Malaysia, the main methods of controlling gastrointestinal nematodes is using chemical anti-parasitic drug or anthelmintic and also by maintaining good p...
