Production of Diplodia scrobiculata and Diplodia pinea pycnidia on ground Austrian pine needle agar medium

The in vitro production of fruiting structures represents an important tool for the morphological identification of fungal genera or species. It is also important for the controlled production of spores to be used in experiments. However, some fungal species do not readily sporulate in pure culture. In the present study we induced the production of pycnidia of Diplodia scrobiculata and D. pinea, two species recalcitrant to sporulation in pure culture, by growing them on two media containing ground Austrian pine needle. The two fungal species grew equally rapidly on both media and pycnidial primordia were produced on the medium surface after only 4 days at room temperature. Conidia matured in less than two weeks and their germination rate at 25°C was about 96%, indicating high viability

Diagnosis and laparoscopic management of a 5-week ectopic pregnancy in a rudimentary uterine horn: A case report

Uterine anomalies result from the failure of complete fusion of the Müllerian ducts during embryogenesis. A unicornuate uterus with a rudimentary horn is the rarest anomaly and results from the failure of one of the Müllerian ducts to develop completely and an incomplete fusion with the contralateral side. Diagnosis and surgical management of a 5-week ectopic pregnancy in a non-communicating rudimentary horn in an 18-year-old nulliparous woman in whom this congenital uterine anomaly was previously unknown are described

Development of a loop-mediated isothermal amplification (LAMP) assay for the identification of the invasive wood borer Aromia bungii (Coleoptera: Cerambycidae) from frass

The red-necked longhorn beetle Aromia bungii (Faldermann, 1835) (Coleoptera: Cerambycidae) is native to east Asia, where it is a major pest of cultivated and ornamental species of the genus Prunus. Morphological or molecular discrimination of adults or larval specimens is required to identify this invasive wood borer. However, recovering larval stages of the pest from trunks and branches causes extensive damage to plants and is timewasting. An alternative approach consists in applying non-invasive molecular diagnostic tools to biological traces (i.e., fecal pellets, frass). In this way, infestations in host plants can be detected without destructive methods. This paper presents a protocol based on both real-time and visual loop-mediated isothermal amplification (LAMP), using DNA of A. bungii extracted from fecal particles in larval frass. Laboratory validations demonstrated the robustness of the protocols adopted and their reliability was confirmed performing an inter-lab blind panel. The LAMP assay and the qPCR SYBR Green method using the F3/B3 LAMP external primers were equally sensitive, and both were more sensitive than the conventional PCR (sensitivity > 103 to the same starting matrix). The visual LAMP protocol, due to the relatively easy performance of the method, could be a useful tool to apply in rapid monitoring of A. bungii and in the management of its outbreaks
