Morphological and molecular characterisation of one new and several known species of the reniform nematode, RotylenchulusLinford & Oliveira, 1940 (Hoplolaimidae: Rotylenchulinae), and a phylogeny of the genus
(Brill, 2016)The reniform nematodes of the genus Rotylenchulus are semi-endoparasites of numerous herbaceous and woody plant roots and are mainly distributed in tropical and subtropical regions. In this study, we provide morphological ... -
Morphological and molecular characterisation of several Paratylenchus Micoletzky, 1922 (Tylenchida: Paratylenchidae) species from South Africa and USA, together with some taxonomic notes
(Brill Academic Publishers, 2014)Pin nematodes of the genus Paratylenchus are widely distributed across the world and associated with many plant species. Morphological identification of Paratylenchus species is a difficult task because it relies on many ... -
Morphological and molecular characterisation of some Criconematidae (Nematoda, Tylenchida): Ogma decalineatus (Chitwood, 1957) Andrassy, 1979, Criconema silvum (van den Berg, 1984) Raski & Luc, 1985 and Neobakernema variable (Raski & Golden, 1966) from South Africa and the USA
(Russian Academy of Sciences, 2017)During recent nematological surveys Ogma decalineatus and Criconema silvum were found in South Africa and Neobakernema variabile was found in California, USA. These three species are morphologically and morphometrically ... -
Morphological and molecular characterisation of some Hemicriconemoides species (Nematoda: Criconematidae) together with a phylogeny of the genus
(Brill Academic Publishers, 2014)Sheathoid nematodes of the genus Hemicriconemoides are migratory root-ectoparasites of many plants including various agricultural crops and fruit trees. They are generally found inhabiting warm areas of the world and ... -
Morphological and molecular characterisation of two new Hemicycliophora species (Tylenchida: Hemicycliophoridae) with a revision of the taxonomic status of some known species and a phylogeny of the genus
(Brill, 2018)Hemicycliophora presently contains 132 valid species of sheath nematodes. Within several samples obtained from surveys in Canada, South Africa, Spain and the USA, we distinguished six valid and six putative unidentified ... -
Morphological and molecular characterization of a marine fish trypanosome from South Africa, including its development in a leech vector
(BioMed Central, 2014)Background Trypanosomes are ubiquitous blood parasites of marine and freshwater fishes, typically transmitted by aquatic leeches. Phylogenetic studies have been dominated by examples derived from freshwater fishes, with ... -
Morphological and molecular characterization of an African freshwater fish trypanosome, including its development in a leech vector
(Elsevier, 2020)Trypanosomes are ubiquitous blood parasites of fishes and at least 16 species were originally described infecting African freshwater fishes. This number was later reduced to six and in the late 1990s it was proposed that ... -
Morphological and molecular characterization of three Helicotylenchus species from Iran
(Magnolia Press, 2018)Three Helicotylenchus species, namely Helicotylenchus digonicus, Helicotylenchus pseudorobustus and Helicotylenchus vulgaris were identified during a nematode survey conducted in Iran. The morphological and molecular ... -
Morphological and molecular characterization of Vicia faba and Phaseolus vulgaris seed-born fungal endophytes
(Academic Journals, 2017)Background: Fungal endophytes are heterotrophic microorganisms that occur inside plant tissues, with some showing adverse effects against insects, nematodes and plant pathogens. Initiatives are underway at the International ... -
