Borrelia burgdorferi, the Lyme disease agent, binds glycosaminoglycans (GAGs) such as heparin, heparan sulfate, and dermatan sulfate. Heparin or heparan sulfate fractions separated by size or charge were tested for their ability to inhibit attachment of B. burgdorferi to Vero cells. GAG chains of increasing length and/or charge showed increasing inhibitory potency, and detectable heparin inhibi...
The effect of heat shock was investigated on lymphoblastoid cell lines Raji and P3HR1 harbouring Epstein-Barr virus (EBV) genomes, and on Vero cells abortively infected with human cytomegalovirus (HCMV). A heat shock at 44 degrees C for 10 min induced the appearance of EBV early antigens in Raji cells and increased the percentage of cells expressing EBV viral capsid antigens in P3HR1 cells. Hea...
Essential oil from Cymbopogon nardus was evaluated for activity against Trypanosoma brucei brucei BS221 (IC50 = 0.31 ± 0.03 μg/mL) and cytotoxic effect on normal kidney (Vero) cells (IC50 = >100 μg/mL). The crude essential oil was subjected to various chromatography techniques afforded active sub fractions with antitrypanosomal activity; F4 (IC50 = 0.61 ± 0.06 μg/mL), F6 (IC50= 0.73 ± 0.33 μg/m...
Subacute sclerosing panencephalitis virus has been isolated with difficulty from brains of infected patients. More strains are needed for the study of the pathogenesis of this virus. To make the isolation more efficient, we selected portions to be examined from the brains of three patients with reference to findings of repeated magnetic resonance and computed tomographic imaging. Three cell lin...
Malaria and leishmaniasis are two of the World's most important tropical parasitic diseases. Thirteen new 2-cyano-3-(4-phenylpiperazine-1-carboxamido) quinoxaline 1,4-dioxide derivatives (CPCQs) were synthesized and evaluated for their in vitro antimalarial and antileishmanial activity against erythrocytic forms of Plasmodium falciparum and axenic forms of Leishmania infantum. Their toxicity ag...
Rift Valley fever viruses carrying mutations of the M gene preglycoprotein region, one lacking NSm protein expression, one lacking 78-kDa protein expression, and one lacking expression of both proteins, were compared in cell culture. All of the mutants and their parent virus produced plaques with similar sizes and morphologies in Vero E6 cells and had similar growth kinetics in Vero, C6/36, and...
Background and Aims: Lemon Balm L (Lamiaceae) has been used in a variety of practical applications in medical sciences. Its antiviral activity against herpes simplex virus type-1 (HSV-1) was investigated in cell culture. Lemon Balm hydroalcoholic extract was found to be non-toxic to Vero cells up to concentration 800 ug/ml and inhibited the growth and development of HSV-1 in dose-dependent mann...
Diarrhea is an important hygienic problem in under development countries. Among pathogenic agents Escherichia coli is the most etiologic agent of diarrhea in children below five years old. Some E. coli strains produce cytotoxins that have cytopathic effect on vero cell and identified as verotoxin. This study performs for resolve frequency of Vero Toxigenic Escherichia coli...
سل یکی از معضلات بهداشتی و پزشکی جامعه بشری است، که از سالیان دور تا کنون باعث خسارات جانی و مالی فراوانی برای نسل بشر شده است.و علی رغم تمام تلاشهای صورت گرفته برای مقابله با این بیماری هنوز ان را به عنوان یکی از مهمترین علل مرگ و میر در دنیا می دانند که سالیانه 2 میلیون نفر را در دنیا به کام مرگ می فرستد. یکی از مهمترین پروتئینهای ایمنی زا در مایکوباکتریوم توبرکلوزیسesat-6است،که یک پلی پپتید...
