Abstract This study examined the gastrointestinal parasitological status of three endangered Sub-Saharan antelope species ( Addax nasomaculatus , Oryx dammah Gazella dorcas ) hosted at Souss-Massa National Park in Morocco. A total 254 faecal samples (80 from addax population, 81 oryx population and 93 population) were analysed to determine prevalence intensity parasites host faeces (expressed a...

Until the 1960s, the chemotherapy of human intestinal and systemic helminthiases was extremely unsatisfactory;' piperazine compounds, bephenium hydroxynaphthoate and pyrantel embonate were, for example, widely used for the former, and diethylcarbamazine (DEC), niridazole, and bithionol for the latter. Table I summarizes some important agents which have recently become available. The first of th...

The nematode Caenorhabditis elegans may be killed by certain pathogenic bacteria and thus is a model organism for studying interactions between bacteria and animal hosts. However, growing nematodes on prey bacteria may influence their susceptibility to potential pathogens. A method of axenic nematode culture was developed to isolate and quantify interactions between C. elegans and potentially p...

One of the many aspects of the relationships between parasite infections and allergic diseases is the possibility that allergens from parasites enhance the TH2 responses, especially IgE production, in allergic diseases such as asthma. In this review we discuss about the allergenic composition of the nematode Ascaris lumbricoides and their potential impact on allergy sensitization and asthma pat...

Concurrent helminth infections have been suggested to be associated with protection against cerebral malaria in humans, a condition characterised by systemic inflammation. Here we show that a concurrent chronic gastro-intestinal nematode infection does not alter the course of murine cerebral malaria. Mice infected with Heligmosomoides polygyrus, and co-infected with Plasmodium berghei ANKA 14 d...

Various interacting factors have been identified to explain why health plans for nematode parasite control, based on conventional epidemiological knowledge and involving pharmaceutical treatments of their sheep hosts have become unsustainable. Of these, the emergence of anthelmintic resistance has had a major impact on the economics of sheep farming, necessitating fundamental managemental chang...

Although infection with any of the three types of Mansonella species that affect humans is often asymptomatic, a large portion of the world’s population is at risk of this vectorborne filarial nematode infection. No previous global review of the epidemiology of mansonelliasis has been conducted. A systematic review of the literature was conducted. Original research articles that provided popula...

Merino lambs born in September and October 1964 were weaned at 4, 6 and 11 weeks of age, at average liveweights of 9 kg, 12 kg, and 19 kg respectively, on to a pasture of phalaris and white clover. The lambs remaining with their mothers for 11 weeks showed the earliest onset of an appreciable worm infection which reached a peak in December about one month after weaning. Similar levels of infect...
