In an outside pot experiment, dry pig manure processed on pine sawdust litter and fermented for seven days by house fly larvae (fermented manure), and pine sawdust applied alone, and in combination with a spring application of inorganic nitrogen fertilizer were used to determine their effects on plant parasitic and free-living soil nematodes on sugar beets (cv. Antek). Non amended soil was used...

Parasites, which are a recently discovered yet ancient dweller in human hosts, remain a great public health burden in underdeveloped countries, despite preventative efforts. Rheumatoid arthritis is a predominantly cosmopolitan health problem with drastic morbidity rates, although encouraging progress has been achieved regarding treatment. However, although various types of methods and agents ha...

It is presented a modality to compute the boundary between the discontinuous (DCM) and continuous (CCM) operating modes in the DC/DC fourth-order PWM converters with parasitic resistances. To reach this goal, an averaged model of the converter has been used. The boundary between DCM and CCM, considered to be the critical load resistance Rcrit, or, equivalently, the critical value of the inducto...

Background & Aims of the Study: Parasitic infections are common in many countries, especially in developing countries and tropical areas. People who deal with foods can be a threat to health of communities. This meta-analysis study was undertaken to determine the prevalence of parasitic infections, such as Ascaris lumbricoides, Entamoeba coli, Entamoeba histolytica, and Giardia...

The objective of this study was to determine the effect of egg age and pre-colonization of cysts by a saprophytic or parasitic fungus on parasitism of Heterodera glycines eggs by other parasitic fungi. In agar and in soil tests, fungi generally parasitized more eggs in early developmental stages than eggs containing a juvenile. The effect of pre-colonization of cysts by a fungus on parasitism o...

BACKGROUND Macrocyclic lactones are arguably the most successful chemical class with efficacy against parasitic nematodes. Here we investigated the effect of the macrocyclic lactone ivermectin on lipid homeostasis in the plant parasitic nematode Globodera pallida and provide new insight into its mode of action. RESULTS A non-invasive, non-destructive, label-free and chemically selective techn...

The impacts of two organic soil amendments on nematode abundance, community structure and soil characteristics were studied in field grown tomatoes. We hypothesized that as the raw (labile form) and composted (non-labile form) manures differ in their chemical composition and effect on microbial activity. Also they will have different effects on soil properties and directly and indirectly affect...

background: protozoa are common in poultry and otherbirds and can cause mild to severe disease. objectives: thisstudy was concerned with the prevalence of parasitic protozoa inwild waterfowl in caspian sea lagoons in the north of iran.methods:atotal of 293 waterfowl belonging to various generaincluding tadorna tadorna (common shelduck),aythya fuligula(tufted duck), aythya ferina (common puchard...

examination of faecal samples of 6,430 school children aged between 2 and 20 years, for gastrointestinal parasites using sedimentation and kato smear techniques was carried out in benin city, nigeria between january 1997 and december 1998. four thousand two hundred and thirty six (65.8%) were infected. three species of protozoa and 8 species of helminths were recorded as follows: entamoeba hist...

background: knowledge about the amphistomid fauna in iranian domestic ruminants depends on the studies conducted almost 30 years ago. the last situation in cattle is introduced here in the provinces in south coast of caspian sea. methods: amphistomid species were collected from cattle at slaughter houses of the provinces gilan and mazanderan in 2010. median sagittal sections were prepared by th...
