The incidence and intensity of metazoan parasites in 3 species of Iraqi amphibians were studied. The amphibians were Rana ridibunda, Bufo viridis and Hyla arborea. Twenty-four species of helminths were encountered, including 16 trematodes, 1 cestode and 7 nematodes. Their respective names are: Polystoma integerrimum, Prosotocus confusus, P. fuelleborni, Pleurogenoides gastroporus, P. medians, S...
UNLABELLED Here we describe and compare the venomic and antivenomic characteristics of both neonate and adult Prairie Rattlesnake (Crotalus viridis viridis) venoms. Although both neonate and adult venoms contain unique components, similarities among protein family content were seen. Both neonate and adult venoms consisted of myotoxin, bradykinin-potentiating peptide (BPP), phospholipase A2 (PLA...
Pouteria campechiana, Pouteria sapota, and Pouteria viridis are tropical plants in the Sapotaceae family that bear edible fruits. The fresh fruits of these three Pouteria species were each extracted, and activity-guided fractionations were performed to identify the antioxidant constituents. Seven polyphenolic antioxidants, gallic acid (1), (+)-gallocatechin (2), (+)-catechin (3), (-)-epicatechi...
Four atrazine-resistant mutants from the purple bacterium Rhodopseudomonas viridis were isolated. Sequence analysis revealed three different mutant strains carrying mutations in the herbicide-binding pocket: i) MAV 2: L212-Glu----Lys, ii) MAV 3: L216-Phe----Ser and iii) MAV 4 = MAV 5: L217-Arg----His, L220-Val----Leu. Except MAV 3 all Rps. viridis mutants are different from those selected by th...
in addition to biochemical, physiological and morphological analysis, molecular studies provide additional information for establishing phylogenetic relationships among different species and strains of the genus dunaliella. in the present study, based on neighbor- joining analysis of the nuclear rdna its sequence, a novel strain of the green algae dunaliella viridis was identified from maharlu ...
Saccharomonospora viridis (Schuurmans et al. 1956) Nonomurea and Ohara 1971 is the type species of the genus Saccharomonospora which belongs to the family Pseudonocardiaceae. S. viridis is of interest because it is a Gram-negative organism classified among the usually Gram-positive actinomycetes. Members of the species are frequently found in hot compost and hay, and its spores can cause farmer...
Launaea taraxacifolia and Amaranthus viridis used by people of Western Africa in the treatment of malaria and related symptoms were assessed for their antiplasmodial value against the chloroquine sensitive strain of Plasmodium berghei. Crude extracts (200 mg/kg) and chloroquine (5 mg/kg) were administered to different groups of Swiss mice. The percentage of parasitemia, survival time, and haema...
Ice-binding protein (IBPs) protect cells from cryo-injury during cryopreservation by inhibiting ice recrystallization (IR), which is a main cause of cell death. In the present study, we employed two IBPs, one, designated LeIBP from Arctic yeast, and the other, designated FfIBP from Antarctic sea ice bacterium, in the cryopreservation of three economically valuable marine microalgae, Isochrysis ...
The production and use of sugarcane in Brazil is very important for bioenergy production and is recognized as one of the most efficient in the world. In our laboratory, Setaria viridis is being tested as a model plant for sugarcane. S. viridis has biological attributes (rapid life cycle, small genome, diploid, short stature and simple growth requirements) that make it suitable for use as a mode...
Crystals of the reaction center (RC) from Rhodopseudomonas sphaeroides with the space group P2(1)2(1)2(1), have been studied by x-ray diffraction. The Patterson search (molecular replacement) technique was used to analyze the data, with the structure of the reaction center from Rhodopseudomonas viridis as a model system. A preliminary electron density map of the reaction center from R. sphaeroi...
