background: to determine the prevalence and intensity of helminths and their zoonotic importance in small rodents inhabiting in the suburban areas of hamadan city,iran. methods: the present survey was conducted on the helminth infections of two species of rodents apodemus sylvaticus (n=60) and mus musculus (n=72) in the suburban areas of hamadan city during 2010-2012. rodents were collected and...
Diet and helminth fauna were analysed in Gallotia caesaris, a small lacertid lizard endemic to El Hierro (Canary Islands, Spain) in order to study the evolutionary and functional relationships between the two traits. This species is omnivorous but consumed a high proportion (82.13%) of plant matter including not only seeds but also leaves and other vegetative parts. Helminth fauna included many...
BACKGROUND Despite the high prevalence of helminth infections among preschool-aged children, control programs in sub-Saharan countries primarily focus on school-aged populations. We assessed the prevalence of helminth infections and determined risk factors for infection among preschool-aged children in the urban setting of Dar es Salaam, Tanzania. METHODOLOGY Starting in October 2015, we cond...
Parasitic helminths establish chronic infections in mammalian hosts. Helminth/Plasmodium co-infections occur frequently in endemic areas. However, it is unclear whether Plasmodium infections compromise anti-helminth immunity, contributing to the chronicity of infection. Immunity to Plasmodium or helminths requires divergent CD4+ T cell-driven responses, dominated by IFNγ or IL-4, respectively. ...
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...
BACKGROUND The poor correlation between allergen-specific immunoglobulin E (asIgE) and clinical signs of allergy in helminth infected populations suggests that helminth infections could protect against allergy by uncoupling asIgE from its effector mechanisms. We investigated this hypothesis in Ugandan schoolchildren coinfected with Schistosoma mansoni and hookworm. METHODS Skin prick test (SP...
SYNOPSIS. Some of the accumulated knowledge on the complex problems involved in the transmission of helminths of domestic animals in the USA is summarized. The lollowing conditions are usually necessary for the development outside the final hosts of infective stages of these helminths: moderate temperatures, adequate moisture, oxygen, and protection from freezing, desiccation and direct sunligh...
background: the aim of this study was to compare superoxide dismutase (sod) activity in fasciola hepatica and fasciola gigantica parasites. materials: f. gigantica and f. hepatica helminths were collected from abattoir and cultured in buffer media for 4 h at 37 °c. excretory-secretory (es) products were collected, centrifuged and stored at - 20 ◦ c. e-s protein concentration was measured by bra...
background: the performance and parasitology of semi-intensively managed west african dwarf (wad) lambs were evaluated following exposure to gastrointestinal helminth infected paddock and varied protein-energy feeds. methods: twenty four lambs obtained from the department of animal breeding and genetics and brought to directorate of university farm (dufarm) of federal university of agriculture ...
background : cats play a crucial role in the epidemiology of gastrointestinal helminthic parasites and also play a major role in transmitting of these parasites through faecal contamination of soil, food or water. the aim of this study was to determine the species of gastrointestinal helminthes parasites in stray cats from a rural area of bandar-e-anzali, iran. method: gastrointestinal helminth...
