Mitochondrial COI gene is valid to delimitate Tylenchidae (Nematoda: Tylenchomorpha) species

Tylenchidae is a widely distributed soil-inhabiting nematode family characterized by a weak stylet, an undifferentiated non-muscular pharyngeal corpus, and a filiform tail. Currently, it comprises 412 nominal species belongs to 44 genera and estimated species number ranged from 2,000 to 10,000 species (Qing and Bert, 2019). Regardless of their abundance, the delimitation of taxa in this group remains poorly documented and highly uncertain. Consequently, there is no consensus regarding their

Staphylococci constitute an important component of the human microbiome. Most of them are coagulase-negative species, whose importance in the pathogenesis of human infections has been widely recognized and is being documented on a regular basis. Until recently, the only well-known coagulase-positive staphylococcus species recognized as human pathogen was Staphylococcus aureus. Previously, the ability to produce coagulase was used as its basic diagnostic feature, because other coagulase-positive

Truffles (Tuber spp.) are ascomycete hypogeous fungi, which form ectomycorrhizae with roots of trees, shrubs and herbaceous plants. Their fruiting bodies are valued for their distinctive aroma. The aroma might be partially due to complex bacterial community which colonizes their fruiting bodies. Some bacterial species are also believed to promote the truffle’ fruitification due to the fixation of nitrogen inside the developing truffles. Although truffles, especially of the species Tuber

Cephalenchus driekieae n. sp. (Nematoda: Tylenchidae) from South Africa, a new member of the genus with a long pharyngeal overlap

The family Tylenchidae (Örley, 1880) is an abundant group of nematodes. Its members are commonly found in vast ecological niches viz. soil, algae, fungi, and plant material (Panahandeh et al., 2018). Currently, approximately 44 genera and 412 species are known in this family (Qing and Bert, 2019). Traditionally, most tylenchids were identified based solely on morphological characters (Geraert, 2008), which led to taxonomic confusions within the family (Qing and Bert, 2019). However, in recent

Reclaimed desert habitats favor entomopathogenic nematode and microarthropod abundance compared to ancient farmlands in the Nile Basin

Research on entomopathogenic nematodes (EPN) in Egypt started in the 1970s, and focused heavily on imported, non-indigenous species (Abd-Elgawad, 2017). Surveys to isolate and identify indigenous EPNs began two decades later (Shamseldean and Abd-Elgawad, 1994). Inconsistent efficacy by expensive EPN products hinders their use by the Egyptian farmers, suggesting a need for further exploration to identify species which are adapted to North African conditions and best suited to infect local insect
