An ascites form of malignant transformed lymphoma cells were treated in vitro with liposomes of 1:1 lecithin-cholesterol in order to increase the cholesterol level of the cell-surface membranes and thereby to increase the rigidity of the lipid layer. This treatment was found to inhibit the rate of killing by ascites tumor after intraperitoneal inoculation into adult mice of 10(4) and 10(5) trea...

a comparative study was conducted to find a reliable and simple method for evaluation of resistance of sugar beet genotypes to rhizoctonia root and crown rot. for this, 12 sugar beet genotypes were used in greenhouse, field and in vitro experiments. the field experiment was performed in micro plots (1×1×2 meter) using randomized complete block design with 4 replications. prior to planting, the ...

Eimeria (E.) tenella (local isolate) sporozoites were adapted on the chorioallantoic membrane (CAM) of 10-12 days chicken embryos and completed its life cycle in 6-7 days at 39 degrees C and 70 per cent humidity. Only 23 embryos (4.6%) were found dead from 1-4 day post inoculation of sporozoites with mild lesions on CAM with no gametocytes but few sporozoites in chorioallantoic fluid (CAF). On ...

OBJECTIVES Systemic antibiotic treatment of Lyme borreliosis is effective during the early stages of the infection, while chronic manifestations of the disease may remain refractory and difficult to treat. This study was carried out in order to evaluate the potential of topically applied azithromycin to eliminate the spirochaetal organisms in the skin of the freshly bitten host and thereby prev...

In the present study, four fungal isolates (Metarhizium anisopliae) were isolated and examined for their sporulation characteristics and virulence against Coptotermes formosanus. Initially fungal strains were isolated through insect bait (Galleria) method. The mortality was significantly varied between 2 to 4 days. nd th In in this study inspection, the mortality of termites was observed after ...

White-footed mice (Peromyscus leucopus), the primary reservoir for Borrelia burgdorferi in the northern midwest and northeastern United States, were experimentally inoculated with an infectious strain or a noninfectious strain of the Lyme disease spirochete and examined for their specific antibody response with the enzyme-linked immunosorbent assay and Western blot (immunoblot) analysis. Immuno...

Meloidogyne incognita penetration and development were studied in roots of highly resistant (PI 96354, PI 417444), resistant (Forrest), and susceptible (Bossier) soybean genotypes. Although more second-stage juveniles (J2) had penetrated roots of PI 96354 and PI 417444 than roots of Forrest and Bossier by 2 days after inoculation, fewer J2 were present in roots of PI 96354 at 4 days after inocu...
