Toxoplasma gondii contain various immunogenic antigens. The most important Toxoplasma antigens are somatic and excreted/secreted antigens. Rhoptry proteins are known as excreted/secreted antigens. These antigens have been proposed as a vaccine candidate against toxoplasmosis. The main objective of the present work was cloning rhoptry protein1 (ROP1) Gene of Toxoplasma gondii (RH) in a cloning...

Taoxoplasma gondii is an important food-borne parasite transmitted primarily from animals to humans through meat consumption, mainly pork and lamb, as well as through oocysts shed by cats. Infection in humans can cause severe fetal malformations, ocular complications or encephalitis. Toxoplasmosis infection during pregnancy, especially in sheep, often results in abortion, representing considera...

Flax fiber-reinforced polymer (FFRP) composites are emerging popular environmental-friendly construction materials. However, their significant creep properties have been a major concern for using FFRP in load-bearing structures. This article presents an investigation of the effect environmental humidity on behavior FFRP. Samples with flax fiber 0°, 90°, and ± 45° were manufactured, respectively...

The efficacy of atovaquone and sulfadiazine was examined alone or in combination for the treatment of mice infected with six Brazilian Toxoplasma gondii strains previously genotyped using the PCR-RFLP assays of the SAG2 gene, in addition to RH strain. Swiss mice were infected intraperitoneally with 10(2) tachyzoites from each strain of T. gondii and treated with 6.25, 12.5, 25 and 50 mg/Kg/day ...

In previous studies it was shown that Pichia guilliermondii strain Z1, isolated from healthy Moroccan citrus Valencia-Late oranges, was effective against Penicillium italicum. Here the effectiveness of strain Z1 was assessed against Penicillium digitatum, the causal agent of green mould, under different temperature (5-25°C) and relative humidity (RH) (45-100%) regimes for its reliable and large...

The aerosol survival in air was determined for Pasteurella tularensis live vaccine strain (LVS) as a function of relative humidity (RH). Three different preparations of bacteria were used: (i) liquid suspension of P. tularensis LVS in spent culture medium; (ii) powders of P. tularensis LVS freeze-dried in spent culture fluid; (iii) P. tularensis LVS freeze-dried in spent culture fluid and then ...

OBJECTIVES The purpose of this study was to evaluate the effects of the angiotensin-converting enzyme (ACE) inhibitor imidapril and the calcium antagonist amlodipine on endothelial function before and after 2, 4, 8, 12, 24 and 48 weeks of treatment. BACKGROUND There are limited data on whether and how long endothelial function is improved after initiation of ACE inhibitor treatment and how th...

Endemic nosocomial Legionnaires disease has occurred at our medical center for several years. Two subtypes of Legionella pneumophila serogroup 1 (UH-1 and RH-1) have been isolated in approximately equal numbers from hospital potable water. However, almost all clinical isolates have been UH-1. To assess potential differences in virulence, 50% lethal doses (LD50) and 50% infective doses (ID50) of...

The elastic modulus of polymeric membranes based on PVOH + H3PO2 TiO2 was studied as a function relative humidity (%RH) and the volumetric fraction water. Tensile stress-strain tests (nominal stress) were performed to determine Young's modulus, yield strength, break stress, strain stress at constant speed 10 mm/min. membrane’s acid concentration kept molar high proton conduction P/OH = 0.3, the...
