The aim of this study was to determine the accuracy and precision of McMaster method with Raynaud's modification in the detection of the eggs of the nematodes Toxocara canis (Werner, 1782) and Trichuris ovis (Abildgaard, 1795) in faeces of dogs. Four variants of McMaster method were used for counting: in one grid, two grids, the whole McMaster chamber and flotation in the tube. One hundred sixt...
Forty-one wild sheep (Ovis ammon orintalis) from Kabodan Island of National Park of Urmia Lake (North-West of Iran), were examined during a period of six months from October 2002 to March 2003, for helminthes and coccidian infection. The numbers of oocyst and eggs per gram of faeces (OPG & EPG) were determined by the centrifuge flotation technique using saturated sugar solution. The rate of inf...

Gastrointestinal helminths can have a detrimental effect on the fitness of wild ungulates. Arctic and Subarctic ecosystems are ideal for the study of host-parasite interactions due to the comparatively simple ecological interactions and limited confounding factors. We used a unique dataset assembled in the early seventies to study the diversity of gastrointestinal helminths and their effect on ...
Worm egg counts have been used for the assessment of nematode infections of sheep for many years. Different methods have been used, but recently the Stoll method (Stoll, 1930) and the McMaster Slide (Gordon & Whitlock, 1939) technique have almost entirely superseded the others. The McMaster technique is the best method, although it suffers from the slight disadvantage that eggs of Trichuris ovi...
Gastrointestinal nematodes (GINs) are serious issue for health of wild sheep kept in captivity. Chemically synthesized anthelmintics regularly used to control these parasites. In recent years anthelmintic resistance and remnant drugs animal products leads use medicinal plants as alternative anthelmintics. current study, the efficacy aqueous, methanolic ethanolic dried leaf extracts Moringa olei...
BACKGROUND There is a worldwide upscale in mass drug administration (MDA) programs to control the morbidity caused by soil-transmitted helminths (STHs): Ascaris lumbricoides, Trichuris trichiura and hookworm. Although anthelminthic drugs which are used for MDA are supplied by two pharmaceutical companies through donation, there is a wide range of brands available on local markets for which the ...
