During a survey of the microsporean fauna of the two-spot red snapper Lutjanus bohar Forsskal, 1775, from the Red Sea off Jizan (Saudi Arabia), a species of Glugea Thelohan, 1891 was found that did not conform to any known species. The species is characterized by the presence of spherical xenomas (ca. 2-5 mm in diameter) in the host body cavity. Examination of the lifecycle stages and mature spores using light and transmission electron microscopy also revealed morphological characteristics typical of species of the genus Glugea.

During a survey of the myxosporean fauna of the golden trevally Gnathanodon speciosus from the Arabian Gulf off Saudi Arabia, a species of Ceratomyxa that did not conform to any known species was recorded. The infection was detected as a large number of mature spores free-floating in the bile. Mature spores were hat- or helm-like in the frontal view with two short and unequal valves. The spores measured 8 (7-9) x 12 (10-14). The two polar capsules were spherical, equal in size and measured 3 (2-4) in diameter with three filament turns.

Two new compounds containing the (acetylido)(cyanido)aurate(I) anion are reported. Their solid-state
structures with the monocation PPN, bis(triphenylphosphane)iminium, are reported as a product containing
a water molecule and an acetone molecule for the phenylacetylide compound, and as a monohydrate
in the case of the t-butylacetylide compound. The gold atom is linearly coordinated with normal
Au–C bonds in both cases (1.97–1.99 Å). Hydrogen bond chains are found from N to water and from water

Four new compounds containing the (chlorido)(2x)(cyanido)xargentate(I) anion (x = 2, 1.63, 1 and 0.5) are
reported. Their solid-state structures with the monocation PPN, bis(triphenylphosphane)iminium, are
described; in a few cases the products also contain solvent molecules. The compounds have the formula
(PPN)2[Ag2Cl3(CN)], (PPN)[Ag(CN)Cl](CH2Cl2) and (PPN)[Ag(CN)1.63Cl0.37](hexane)0.5 and (PPN)[Ag(CN)2]
(CH2Cl2). Apart from the molecular structures and the synthetic process, also the solid-state luminescence
has been studied.

Three new compounds containing the bis(triphenylphosphane)iminium cation (PPN+) with ClO4
−, BF4
− and
[AgCl2]− as counter anions have been synthesized and structurally characterized. The two derivatives with ClO4
−
and BF4
− were found to be isostructural by single crystal X-ray diffraction. Interestingly, the three compounds
show extremely potent antiproliferative effects against the human cancer cell line SKOV3. To gain insights into

During a survey of myxosporean parasites of marine fishes from the Arabian Gulf in Saudi Arabia, spores of Ceratomyxa husseini n. sp. were found in the gall-bladders of 50 out of 148 specimens (33.8%) of the yellowfin hind Cephalopholis hemistiktos (Ruppell) (Perciformes: Serranidae). The rates of infection showed a seasonal fluctuation, with the highest prevalence in winter and the lowest in autumn. The mature spores appeared arched in frontal view with rounded valve ends and a slightly discriminated curved suture line and measured 8-9 x 14-18 (9 x 16) mu m.

The purpose of this study is to provide information on the leech fauna of North Africa. This overview is based primarily on collected material, data from the literature and material in museum collections. A total of 37 species belonging to 6 families and 19 genera are presently known. Among these species, eight represent new records for North African countries. This report includes the first records for Tunisia of one freshwater leech, Helobdella stagnalis (Linneaus, 1758), and one marine leech, Trachelobdella lubrica (Grube, 1840).
