From biology to biotechnology: Host‐regulation factors from parasitoid wasps are a source of bioactive molecules with translational potential

Insect Molecular Biology, EarlyView.
Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.

First Detailed Record of Jikradia olitoria (Hemiptera: Cicadellidae) in the Swiss Southern Alps and Evaluation of Its Current Potential as a Vector of 16SrV‐Phytoplasmas

Journal of Applied Entomology, EarlyView.
ABSTRACT Jikradia olitoria Say is a Nearctic leafhopper that was recently reported in several European countries. Given its role as the vector of phytoplasmas associated with Grapevine Yellows diseases (GYD) in its native range, its presence in European vineyard agroecosystems could represent an important phytosanitary risk.

Application of nested PCR for diagnosis of histoplasmosis

Journal of Infection and Chemotherapy, 2013
Histoplasmosis is a fungal infection that, although not endemic in Japan, has seen a rise in the number of Japanese cases since the mid-1980s. Diagnosis of the disease is not straightforward, and the main method of detection, fungal culture (which has biosafety-related issues), is of low sensitivity in general.

Nested Polymerase Chain Reaction (PCR)

Cold Spring Harbor Protocols, 2019
Nested polymerase chain reaction (PCR) is used in situations in which it is necessary to increase the sensitivity and/or specificity of PCR, for example, when amplifying a particular member of a polymorphic gene family or when amplifying a cDNA copy of an mRNA present at very low abundance in a clinical specimen containing a heterogeneous population of

Comparison of the Specificity and Sensitivity of PCR, Nested PCR, and Real-Time PCR for the Diagnosis of Histomoniasis

Avian Diseases, 2005
Blackhead, also known as enterohepatitis, is caused by a protozoan parasite called Histomonas meleagridis. Clinical symptoms are nonspecific. Until now, diagnosis has been mainly based on postmortem lesions and microscopical and histopathological examination.

NESTED-PCR ASSAYS FOR DETECTION OF PHYTOPLASMAS IN STRAWBERRY

Acta Horticulturae, 1997
Flower and fruit virescence and phyllody are known to be associated with the presence of phytoplasmas in symptomatic tissues. During surveys in North and South Italy symptomatic and asymptomatic strawberry samples were examined by nested polymerase chain reaction (PCR) to verify the presence of phytoplasmas using 16S ribosomal DNA primers.

Multiplex nested PCR for Brazilian Alphavirus diagnosis

Transactions of the Royal Society of Tropical Medicine and Hygiene, 2004
A reverse-transcriptase PCR (RT-PCR) and a multiplex nested PCR were developed for the rapid detection and identification of 14 Brazilian alphaviruses. Using Alphavirus genus-specific primers in a RT-PCR, we obtained amplified products of 434 bp. Species-specific primers were selected and simultaneously tested in a multiplex nested PCR.

Detection of bovine gammaherpesviruses by a nested duplex PCR

Journal of Virological Methods, 2004
The two bovine gammaherpesviruses (Alcelaphine herpesvirus 1, AlHV-1; Bovine herpesvirus 4, BoHV-4) are distributed worldwide in cattle populations. Since the animals are frequently infected latently with no or low seropositivity, a DNA based diagnostic method would be useful for surveys and detection of these viruses.
