Oscheius microvilli n. sp. (Nematoda: Rhabditidae): A Facultatively Pathogenic Nematode from Chongming Island, China

A new species, Oscheius microvilli n. sp., was found on Chongming Island (Shanghai, China). The new species is morphologically similar to the type strain of Oscheius myriophilus, but can be distinguished from it and other species of Oscheius on the basis of unique morphological characteristics of the bursa as well as male papillae. In this new species, the male bursal papillar formula is 2, 1, 3, 3 with everted tips in the first, fifth, and seventh pairs. The bursal rim is jagged

Sonographic assessment of the anatomy and common pathologies of clinically important bursae

, predictable and defined spots. Adventitial bursae are formed later during life, at sites of chronic friction or pressure, and are not lined with any synovial layer. There are about 160 different constant bursae in the human body(2). Bursitis refers to the inflammation of a bursa, and it is characterized by synovial thickening, increased amount of fluid within the bursa, localized pain near the inflammation, and adjacent soft tissue swelling(3). Bursitis occurs in many pathological conditions. They include

surrounding low-echogenicity granulation tissue Adventitial bursitis Adventitial (submetatarsal) bursitis refers to inflammation associated with adventitious bursae; these are not permanent natural bursae, but instead develop in adults in sites where subcutaneous tissue is exposed to high pressure or friction(14). Under such conditions, formation of subcutaneous adventitial bursa begins as a coalescence of small spaces in loose connective tissue; the walls become progressively differentiated from

lamina/calomus is complex and smoothly curved to distal end. Distal ends of spicule have rounded terminus. Two pairs of papillae are present: one pair is subventral precloacal papillae (P2) located at the same level of cloacal opening, and the other pair is subventral postcloacal papillae (P3) located at mid of the tail. Tail is conoid ventrally curved with several tubercles. Bursa is absent. Type host and locality The type material was isolated from declining Chinese pine, Pinus tabuliformis

group and insectivora group. Diagnostic characters of both the groups are unique; species under the insectivora group are characterized by leptoderan bursa, crochet needle-shaped spicules and normal rectum, whereas the dolichura group has peloderan bursa, probe head spicule tips and expandable rectum. On the basis of morphological and molecular studies, Sudhaus (2011) characterized the family Rhabditidae by generalized body plan into three groups, Pleiorhabditis, Synrhabditis, and Anarhabditis.

sac well developed, 15 (14 to 17) mm long, female tail elongate-conoid with pointed terminus; and male with adanal bursa and spicules 21 to 22 mm long (n = 2). The new species comes close in morphology and morphometrics to five known species of the genus, namely N. affinis, N. hexaglyphus, N. persicus, N. taylori, and N. uniformis. Molecular analyses of the partial 18S, D2/D3 expansion segments of the partial 28S and internal transcribed spacer (ITS) revealed this as a new species. The sequences

The tail is conical, annulated with hyaline, and the tail tip is pointed (Figs. 1I, 2I, 4F,G,H). Molecular characteristics D2–D3 of 28S rDNA The alignment of D2–D3 of 28S rDNA sequences contained 31 sequences including the sequences from two outgroup taxa (Psilenchus spp. and Rotylenchulus macrosoma). The length of alignment was 602 bp. The D2–D3 of 28S rDNA sequence of

Description of Deladenus brevis n. sp. (Sphaerularioidea: Neotylenchidae) from Iran: a morphological and molecular phylogenetic study

The genus Deladenus was erected by Thorne (1941) with D. durus (Cobb, 1922) Thorne (1941) as its type species. Compared to other genera in the family Neotylenchidae (Thorne, 1941), the genus is characterized by its low cephalic region, small stylet, pharyngo-intestinal junction anterior to nerve ring, excretory pore at the level with, or immediately behind the nerve ring, pharynx lacking a median bulb, long overlap of the glands, no post-vulval uterine sac (PUS), and males with bursa. The genus

According to the classification by Siddiqi (2000), Paurodontella belongs to the subfamily Paurodontinae (Thorne, 1941), family Paurodontidae (Thorne, 1941), superfamily Sphaerularioidea (Lubbock, 1861), suborder Hexatylina (Siddiqi
