Helminth parasitism of food and dairy animals has been responsible for significant economic losses throughout the world. Although a number of helminth parasites affect ruminants, but Haemonchus contortus and Ostertagia ostertagi are of paramount importance as they affect their hosts in a number of ways and often result in their death. The aim of the present trial was to do a comparative analysi...

Untreated tropical parasitic co-infections appear to speed the progression of HIV-1 disease. However, to date, there have been few studies conducted in resource limited settings to ascertain the interaction of parasitic co-infection where HIV/AIDS management largely depends on CD4+ T lymphocyte cells counts and WHO clinical staging. This study aimed to determine the prevalence of parasites, the...

Nine species of nematodes, unidentified larval nematodes, three species of trematodes, two species of acanthocephalans and a single species of chewing louse were collected from 1993 to 1995 from 25 introduced whooping cranes (Grus americana) in Florida (USA). In spite of a quarantine procedure involving anthelmintic therapy, three helminth parasites may have been introduced from captive populat...

The helminths of 25 kudu, Tragelaphus strepsiceros, from 3 localities in the eastern Cape Province were collected, counted and identified. The majority of kudu harboured no worms, and the burdens of those infected were small. A race of Cooperia rotundispiculum, a Dictyocaulus sp., a Haemonchus sp., Nematodirus helvetianus and Ostertagia ostertagi were recovered. Two parasites, Nematodirus helve...

Twenty-eight hog-nosed skunks (Conepatus leuconotus), 23 striped skunks (Mephitis mephitis), and nine spotted skunks (Spilogale gracilis) from an area of sympatry in west-central Texas were examined for helminth parasites. Shared helminth species among all three host species were one nematode (Physaloptera maxillaris), two acanthocephalans (Pachysentis canicola, Macracanthorhynchus ingens), and...

Forty-three specimens of Leptodactylus podicipinus (Anura: Leptodactylidae) were collected in the south-eastern Pantanal, municipality of Corumbá, State of Mato Grosso do Sul, Brazil in February and July 2007, and examined for endoparasites. Forty (93%) specimens were infected with at least one helminth species. The predominant parasites were nematodes (Aplectana sp., Cosmocerca podicipinus, Os...

Helminth parasites are of considerable medical and economic importance. Studies of the immune response against helminths are of great interest in understanding interactions between the host immune system and parasites. Effector immune mechanisms against tissue-dwelling helminths and helminths localized in the lumen of organs, and their regulation, are reviewed. Helminth infections are character...

background: the aim of the study was to determine the helminthic species occurring in great gerbil rhombomys opimus collected from maraveh tappeh, golestan province, northeast iran. methods : during 2010-2011, a total of 77 r. opimus were captured from rural areas of maraveh tap-peh, golestan province, using sherman live traps and examined for infectivity with any larva or adult stages of helmi...

a survey of helminth parasites of domestic fowl carried out in faisalabad (pakistan) between 1994 and 1996 showed a high prevalence of nemaodes infestation in broiler and local poultry. ascardia galli and heterakis spp. were more prevalent in both groups of birds. syngamus tracheae and capillaria spp. were also present in both groups . raillietina spp. were the only cestode found in both the gr...
