Cystic hydatid disease is caused by cystic larval (metacestode) stages of Echinococcus granulosus. This parasite can potentially occur all over the world especially in Mediterranean and Middle East countries and some parts of Africa, Latin America and China which have major foci of human infections. The cyst wall of metacestodes consists of inner, middle and external layers. To date, little att...

Screening of a new strain of Streptomyces collinus, Lindenbein, A 19006, against Salmonella gallinarum led to the isolation of a new antibiotic. Examination of physical data and identification of hydrolysis products permitted the identification of this new metabolite as fumarylcarboxyamido-L-2,3-diaminopropionyl-L-alanine (I). The Gram-negative activity of the new antibiotic is inhibited by D-g...

1. The incorporation of d-[1-(14)C]mannose, d-[2-(3)H]mannose and N-acetyl-d-[1-(14)C]-glucosamine into glycoproteins and lipid-linked intermediates of mammary explants obtained from lactating rabbits was studied. The amount of radioactivity incorporated into lipid-linked intermediates was very low compared with the incorporation into protein. Most of the radioactivity incorporated into the chl...

Filtrates of cultures of bacteria, such as Escherichia coli (3), Neisseria meningitidis (11), and Bacillus prodigiosus (Serratia marcescens) (4, 10) have been shown in laboratory animals to have inhibitory effects on cancer growth. Relatively pure preparations from Serratia marcescens culture filtrates have been used with equivocal results in patients with malignancies (8). In general, the effe...

fermentation of 49 carbohydrates and oxidation and assimilation of 96 substrates were examined for ten beauveria bassiana isolates. principal component analysis indicated that there are significant differences among isolates for utilization of some substrates. esculine and d- glucose were positively fermented by all isolates. isolates were grouped into four clusters on the basis of hierarchial ...

Bandeiraea simplicifolia plant seeds contain a family of five alpha-D-galactopyranosyl-binding isolectins (BS I-A4, A3B, A2B2, AB3, B4) and N-acetyl-D-glucosamine-binding lectin (BS II). After Pi/NaCl extraction and ammonium sulfate fractionation BS II is specifically adsorbed onto p-aminobenzyl-1-thio-N-acetyl-beta-D-glucosaminide-succinylaminohexylaminyl--Sepharose-4B. The BS I isolectins pas...
