A highly virulent strain of Francisella noatunensis subsp. orientalis, STIR-GUS-F2f7, was isolated from moribund red Nile tilapia (Oreochromis niloticus) farmed in Europe. In this communication, the complete genome sequencing of this bacterium is reported.

Using enzyme electrophoresis and nematocyst analysis, the sympatrically occurring "light" and "dark" color morphs of the sea anemone Anthopleura orientalis from the Sea of Japan were shown to be two valid species. The "light" morph was identified as A. orientalis (Averintsev, 1967 Issledovaniya fauny morei: Vyp. 5 (13). Nanka, Leningrad, pp. 62-77), while the "dark" morph was designated as Anth...

Hirudo medicinalis has virtually an obligatory symbiotic relationship with the bacterium Aeromonas hydrophila (= Pseudomonas hirudinis), the only species of bacteria which lives in its gut (Zirpolo 1923; Lehmensick 1941, 1942; Hornbostel 1941; Büsing 1951; Büsing et al. 1953; Wilde 1976; Jennings and Van der Lande 1967; Whitlock, O'Hare, Saunders and Morrow 1983). Aeromonas hydrophila is import...

From the methanolic extract of the underground parts of Globularia orientalis, a new antioxidant sugar ester was isolated. The structure of the new compound, globularitol (1), was identified as 6-O-feruloyl-beta-D-glucopyranosyl-(1-->6)-glucitol by spectroscopic methods (1D and 2D NMR, ESI- and FAB-MS) and confirmed by chemical means.

The osmoregulatory ability and salinity tolerance of four species of decapod crustaceans (Decapoda: Natantia) were evaluated to test the degree of physiological adaptation to variations in salinity (2 d exposure to 10, 20, 25 and 32. The ecophysiological salinity tolerance of two penaeids (Metapenaeus joyneri and Penaeus semisulcatus) and two palaemonid species (Palaemon pacificus and Exopalaem...

BACKGROUND Six plants from Thailand were evaluated for their cytotoxicity and apoptosis induction in human hepatocarcinoma (HepG2) as compared to normal African green monkey kidney epithelial cell lines. METHODS Ethanol-water crude extracts of the six plants were tested with neutral red assay for their cytotoxicity after 24 hours of exposure to the cells. Apoptotic induction was tested in the...

OBJECTIVE To investigate the endemic characteristics of Metorchis orientalis (M. orientalis)in the Huainan area, Anhui province, China. METHODS The first-intermediate host, second-intermediate host and reservoir hosts were collected, and the endemic characteristics of M. orientalis were examined through field investigation and artificial infection. RESULTS Investigation was completed in 89 ...

According to the World Health Organization’s reports, leishmaniases in humans are caused by 20 species of protozoa, belonging to the genus Leishmania1. The parasites are transmitted by the bite of a female tiny, 2–3 mm long insect vector, the phlebotomine sandfly1. Leishmaniasis endemic areas in Kenya are—West Pokot, Kitui, Machakos, Meru, Koibatek and Kajiado districts2–6. Kala-azar (Visceral ...
