Infection of cat flea, Ctenocephalides felis, larvae by the entomophilic nematode Neoaplectana carpocapsae was accomplished in the laboratory. The Breton strain of N. carpocapsae provided higher larval mortality at lower dosages than did the DD-136 strain. Adult nematodes were evident in the insect hemocoel after 48 h; however, no infective third-stage larvae were produced. Larval flea infectio...

Ascaris lumbricoides is a nematode parasite, endemic in the Middle East and South America, especially in rural countries. Ascariasis infection causes about 20 000 deaths every year [1], usually as a result of intestinal occlusion, and it contributes to infant malnutrition [2]. Poor sanitation is usually the most important risk factor for infection, and women are more affected because progestero...

De novo expression of Muc5ac, a mucin not normally expressed in the intestinal tract, is induced in the cecum of mice resistant to Trichuris muris infection. In this study, we investigated the role of Muc5ac, which is detected shortly before worm expulsion and is associated with the production of interleukin-13 (IL-13), in resistance to this nematode. Muc5ac-deficient mice were incapable of exp...

Effective biosafe management strategies are used to decrease world crop damage produced by plant-parasitic nematodes. This study evaluated the efficiency of hydroxyapatite nanoparticles (n-HAP) and mycorrhizal fungi control Meloidogyne incognita infecting tomato plants. Application n-HAP significantly increased juveniles’ mortality (195.67%) egg hatching inhibition percentage (80.71%) compared ...

Influence of a nematode immunomodulator and a nematode infection on two models of allergic disease Parasitic worms, like filariae, have the intriguing capacity to modulate immune responses directed against them, and therefore can persist up to years in a host. This immunomodulation does not only protect the parasite but was found to mediate a negative correlation between infections with parasit...

One hundred fifty rhizobacteria isolated from roots of Swiss chard grown in a soil suppressive to the sugar beet cyst nematode, Heterodera schachtii, were tested for their influence on the nematode's ability to hatch and infect roots. Two screening systems were used that focused on the ability of bacteria to inhibit either nematode hatching or root infection. Most of the bacterial strains reduc...

Introduction: Strongyloidiasis is a systemic disease caused by the nematode Strongyloides stercoralis. unique among parasites in that it can remain undetected for decades. Although patients may present with typical symptoms of skin rash, cough or diarrhoea, rare manifestation infection pseudopolyposis colon. This case highlights finding patient strongyloidiasis negative stool studies. Case desc...

dirofilaria immitis is an important filarial nematode in dogs. in this study, age and sex distribution of this zoonotic nematode among dogs were investigated in northwest of iran in meshkin-shahr city. molecular characteristics of the isolates, based on cytochrome oxidase subunit 1 (cox1) gene were compared to the isolates from other areas of the world.blood samples were collected from 91 dogs ...

Entomopathogenic nematode infective juveniles are likely to encounter both uninfected and infected insects and host quality depends on the stage of the infection. We hypothesized that nematode response to infected hosts will change over the course of an infection. Here, we tested this hypothesis by focusing on the influence of host infection status on long-range attraction to host volatile cues...
