BACKGROUND The current antibody tests used for monitoring in lymphatic filariasis (LF) elimination programs suffer from poor specificity because of the considerable geographical overlap with other filarial infections such as Loa loa (Ll), Onchocerca volvulus (Ov), and Mansonella perstans (Mp). METHODS Using bioinformatics to assemble into contigs 2048 expressed sequence tags (ESTs) from the L...

The use of tanniferous plants or tannins represents one alternative approach to the control of gastrointestinal parasites in ruminants but most data have been obtained in sheep. The current study was therefore performed in goats with two objectives: firstly, to investigate the effects of condensed tannins (CT) on adult populations of Trichostrongylus colubriformis and Teladorsagia circumcincta;...

Understanding vector-parasite interactions is increasingly important as we move towards the endpoint goals set by the Global Programme for the Elimination of Lymphatic Filariasis (GPELF), as interaction dynamics may change with reduced transmission pressure. Elimination models used to predict programmatic endpoints include parameters for vector-specific transmission dynamics, despite the fact t...

The ability of animals to cope with an increasing parasite load, in terms of resilience and resistance, may be affected by both nutrient supply and demand. Here, we hypothesized that host nutrition and growth potential interact and influence the ability of mice to cope with different parasite doses. Mice selected for high (ROH) or low (ROL) body weight were fed a low (40 g/kg; LP) or high (230 ...

OBJECTIVE To test the ability of a single injection of a sustained-release formulation of moxidectin (moxidectin SR) to protect dogs against heartworm infection for 180 days after inoculation with infective third-stage larvae (L3) of Dirofilaria immitis. ANIMALS 32 adult mixed-breed dogs. PROCEDURE Dogs were allocated to 4 groups on the basis of weight and sex. Dogs were injected SC with sa...

Survival of two British steinernematids, one a strain of Steinemema feltiae (Filipjev) [ = S. bibionis (Bovien)], and the other an undescribed species designated Steinernema sp. (Nashes strain) was assessed after storage of infective juveniles in sterile sand at 5 "C and 15 "C and was measured by their motility (ability to be extracted by mini Whitehead trays). Infectivity after storage at the ...

we report a case of human nasal myiasis caused by flower fly larva in a 14-year-old rural girl in central province of iran. entomological studies on larva showed the larva as eristalis tenax which is a rarely cause of nasal myiasis. this is the first reported case of e. tenax larva causing human nasal myiasis in iran.

Gnathostoma spinigerum is a common human tissue parasite in Thailand. The swamp eel is the major intermediate or paratenic host for this parasite. The high prevalence of the infective third stage larvae (L3) of this parasite in the rainy season has been noted in previous studies. During June 1999 (rainy season), we performed a cross-sectional survey of the prevalence and the intensity of G. spi...

The objective of this study was to assess antagonism of nematophagous fungi and species producers metabolites and their effectiveness on Haemonchus contortus infective larvae (L3). Assay A assesses the synergistic, additive, or antagonistic effect on the production of spores of fungal isolates of the species Duddingtonia flagrans, Clonostachys rosea, Trichoderma esau, and Arthrobotrys musiformi...

Strongyloidiasis is a parasitic disease, caused by a nematode helminth, Strongyloides stercoralis. The true prevalence of S. stercoralis is likely underestimated because infection is often subclinical. Currently, an estimated 100 million people are infected worldwide in more than 70 countries (Concha et al., 2005 -. Segarra et al., 2007). Though many advances have been made in the diagnosis and...
