Quorum sensing (QS) plays an important role in virulence, biofilm formation and survival of many pathogenic bacteria including Pseudomonas aeruginosa. This signalling pathway is considered as novel and promising target for anti-infective agents. In the present investigation, effect of the Sub-MICs of clove oil on QS regulated virulence factors and biofilm(More)
Two new species of Chronogaster in India were described and illustrated, based on light and scanning electron microscopy. Chronogaster neotypica n. sp. collected from a sewage slurry was characterized by a medium-sized body, a ventral tail mucro without additional spines, absence of longitudinal incisures in lateral fields, and by the presence of(More)
Ten species of the superfamily Mononchoidea from fourteen populations collected during a survey of terrestrial and freshwater habitats of North India, are described and illustrated. The species include Clarkus papillatus (Bastian, 1865) Jairajpuri, 1970, Prionchulus muscorum (Dujardin, 1845) Wu & Hoeppli, 1929, Mylonchulus contractus Jairajpuri, 1970, M.(More)
This paper describes a new and two known species of Paroigolaimella collected from India. Paroigolaimella helalii n. sp. is characterized by having conspicuous sexual dimorphism in the stoma and pharynx, ovaries with a sphincter separating the mature oocyte from developing ones, a vagina leading to a strong ovijector, a pore-like vulva with cuticular flap;(More)
The paper deals with description of three new and two known species of Tripylidae Örley, 1880. Two new and a known species of the genus TripylinaBrzeski, 1963 while one new and one known species of Trischistoma are described. Tripylina ymyensis n. sp. is characterised by robust body; long, slender outer labial setae; stoma with thick cuticularised wall(More)
This paper deals with the descriptions and diagnoses of the species of the relatively rare and poorly-understood genus Goffartia Hirschmann, 1952. A comparative account of the salient morphological characters including stoma, amphids, pharynx, and the male accessory sex organs of the six species viz., G. africana (Micoletzky, 1915) Hirschmann, 1952; G.(More)
Three new species of the genus BrevitobriusTsalolikhin, 1981 are described. Brevitobrilus glandulatus n. sp. is characterized by conspicuous sphincter between pars dilatata and uterus; two pairs of vaginal glands; spicules having elliptical capitula with small proximal stiffening piece; proximally-arcuate gubernaculum; S3 and S4 smaller than other(More)
A new genus, one new and two known species belonging to family Rhabdolaimidae are described and illustrated. Mediolaimus n. gen. is characterized by small-sized body; papilliform outer labial and cephalic sensilla; long, tubular stoma with stegostom having relatively larger dorsal and smaller sub ventral denticles at same level; cylindrical pharynx with(More)
BACKGROUND The clade Diplogastridae Micoletzky 1922 largely represents the bacterivorous or predatory nematodes that very often demonstrate phoretic, necromenic or parasitic associations with insects (Sudhaus and Fürst von Lieven 2003). That is the reason, much of the diversity of the family remains undocumented because of their absence from routine soil(More)
The paper contains descriptions of two new species of the genera Pterygorhabditis Timm, 1957 and Aspidonema (Sachs, 1949) Andrássy, 1958 belonging to the families Pterygorhabditidae Goodey 1963 and Bunonematidae Micoletzky 1922, respectively. Species were procured from fixed samples, collected earlier from aquatic habitats. Pterygorhabditis punctata n. sp.(More)
