Infection with helminth parasites typically evokes a T helper 2-cell response in the mammalian host. Interleukin (IL)-4 and IL-13 are important in the rapid expulsion of parasitic nematodes, with the absence of either cytokine being compensated for by the other. However, the IL-4 and IL-13 common signaling molecule, signal transducer and activator of transcription 6 (STAT-6) appears to be manda...

“Back to nature” is an increased demand nowadays, for using plants in therapy “instead of using synthetic drugs that may have adverse effects. Grape seed extract (Proanthcyanidins) and Selenium possesses a wide array of pharmacological and biochemical actions. Hymenolepiasis and Passulurus infections are considered as common health problems worldwide. In the present study, Grape seed extract an...

BACKGROUND There are few reports in the literature of invasive infection caused by Brevundimonas vesicularis in patients without immunosuppression or other predisposing factors. The choice of antimicrobial therapy for bacteremia caused by the pathogen requires more case experience to be determined. CASE PRESENTATION The case of a 40-year-old previously healthy man with subacute endocarditis p...

The viral genome-linked protein (VPg) of Potyviruses is covalently attached to the 5' end of the genomic RNA. Towards biophysical characterization, the VPg coding region of Cardamom mosaic virus (CdMV) was amplified from the cDNA and expressed in E. coli. Most of the expressed VPg aggregated as inclusion bodies that were solubilized with urea and refolded with L-arginine hydrochloride. The vari...

Plasmid pCMS1 was isolated from Pseudomonas diminuta MG, a strain which constitutively hydrolyzes a broad spectrum of organophosphorus compounds. The native plasmid was restricted with PstI, and individual DNA fragments were subcloned into pBR322. A recombinant plasmid transformed into Escherichia coli possessed weak hydrolytic activity, and Southern blotting with the native plasmid DNA verifie...

Immunosuppressants have been extensively used to increase the susceptibility of various laboratory animals to several species of nematodes (Campbell , 1963; 1968; Campbell & Collette, 1962 ; Di Netta , Katz & Campbell , 1972 ; Miller, 1966; Mougeot & Lancastre, 1970 ; Parker, 1961; Ritterson, 1959 ; Wiest, 1972; Wakelin, 1970). Only a few of these compounds have been used to increase susceptibi...

BACKGROUND Purified water for pharmaceutical purposes must be free of microbial contamination and pyrogens. Even with the additional sanitary and disinfecting treatments applied to the system (sequential operational stages), Pseudomonas aeruginosa, Pseudomonas fluorescens, Pseudomonas alcaligenes, Pseudomonas picketti, Flavobacterium aureum, Acinetobacter lowffi and Pseudomonas diminuta were is...
