Potential of the fungal feeding nematode Aphelenchus avenae to control fungi and the plant parasitic nematode Ditylenchus destructor associated with garlic

Publication date: Available online 17 January 2020Source: Biological ControlAuthor(s): Shunsuke Haraguchi, Toyoshi YoshigaAbstractTogether with several fungi, the plant parasitic nematode Ditylenchus destructor is among the pathogens that cause serious damage to garlic production areas in Japan. Because D. destructor is a plant and fungal feeder, its infestation may be influenced by the garlic plant-associated fungi and suppressed through control of those fungi. However, no information is currently available regarding the interaction between the nematode and the fungi. Aphelenchus avenae is a non-parasitic fungivorous nematode, which can potentially control plant-pathogenic fungi. Assuming an interaction between the garlic-associated fungi and D. destructor, A. avenae may contribute to suppress D. destructor through fungal control. The present study investigated the interaction between the fungi isolated from garlic and D. destructor as well as the preference of D. destructor and A. avenae for those fungi, aiming to control the fungi and D. destructor using A. avenae. Most fungi isolated from garlic attracted both D. destructor and A. avenae, allowing their propagation. In vitro experiments involving the simultaneous inoculation of D. destructor and A. avenae on a fungus mat showed a better propagation of A. avenae than D. destructor on several fungi as well as the suppression of the D. destructor propagation rate. Similarly, pot experiments involving the simultaneous inocula...

This study supports the use of PCR as an alternative or adjunct to the morphological identification of nematode larvae in formalin-fixed histopathological samples, as well as showing that in investigation of larva migrans, PCR has greatest chance of success from sections where nematode larvae are evident histologically. The identification of Toxocara cati from lesions of larva migrans in kiwi reflects an indirect, parasite-mediated effect of an invasive mammalian species on a native species.Graphical abstract

(Clemson University) In the quest to develop more effective treatments for parasitic diseases, scientists look for weaknesses in the organisms' molecular machinery. A team of College of Science researchers at Clemson recently contributed to that understanding by discovering the function of a specific protein in the three related parasites that cause African sleeping sickness, Chagas disease and Leishmaniasis -- diseases that are sometimes fatal and afflict millions worldwide.

After watching the movie I realized the parallels of being a pharmacist to the movie Parasite. At the beginning I got accepted to Pharmacy and I thought I would escape the slums and be among the rich. However this was just a lie. After many years, I realized the student loans and hard retail environment has not really done anything special for me. I am stuck making huge student loan payments and working away my life with little to no enjoyment at high stress levels. The final scene where... What Parasite made me realize

Conclusions/SignificanceThe study results provide a rich insight into important outcomes for CL treatments, as well as related topics, from the perspective of a diverse patient population. Among the outcomes identified, we argue that those related to quality of life as well as recurrence should be included to a greater extent for assessment in clinical trials, and discuss the suitability of measurement instruments such as the Dermatology Quality of Life Index (DLQI). Interviews also point out the potential need to address concerns related to parasitological cure or scar formation, such as social stigmatization and disabili...

Ikuo Igarashi Cinnamomum verum is a commonly used herbal plant that has several documented properties against various diseases. The existing study evaluated the inhibitory effect of acetonic extract of C. verum (AECV) and ethyl acetate extract of C. verum (EAECV) against piroplasm parasites in vitro and in vivo. The drug-exposure viability assay was tested on Madin-Darby bovine kidney (MDBK), mouse embryonic fibroblast (NIH/3T3) and human foreskin fibroblast (HFF) cells. Qualitative phytochemical estimation revealed that AECV and EAECV containing multiple bioactive constituents namely alkaloids, tannins, saponins, te...

In conclusion, taller body height at the entry to adulthood, supposed to be a marker of early-life environment, is associated with lower risk of dementia diagnosis later in life. The association persisted when adjusted for educational level and intelligence test scores in young adulthood, suggesting that height is not just acting as an indicator of cognitive reserve.

In spite of the strenuous endeavors, a T. gondii vaccine for clinical use remains unreported to date. In the present study, we generated virus-like particles (VLPs) containing T. gondii apical membrane antigen 1 (AMA1) and assessed its efficacy in a murine model. VLPs w...

The disease cost the lives of more than 400,000 people, mainly in Africa. In spite of great efforts aimed at developing better prevention (i.e., a highly effective vaccine), diagnosis, and treatment methods for malaria, no efficient solution to this disease ...
