Aims: To investigate the variations in total protein content and anti-oxidative enzymes blackgram genotypes showing various levels of resistance against aphid-mediated Urdbean leaf crinkle disease (ULCD).
 Study Design: Completely Randomized Design.
 Place Duration Study: The studies were carried out at Insectary belonging to Department Agricultural Entomology Centre Innovation Colleg...

Active anterograde transport of herpes simplex virus Type 1 (HSV-1) in neurons is often assumed based on early appearance of infection in postsynaptic target cells of a primary infected cell, and is further logically inferred by good evidence of microtubule-motor based mechanisms of retrograde transport. However, direct evidence of mechanisms of anterograde movement of newly synthesized virus i...

Conventional tube cell culture was compared with a 2 day and 5 day spin-amplified shell vial indirect immunofluorescence assay for the detection of mumps virus in swabs from the area of Stensen's duct. The sensitivity and specificity of the shell vial assay were 95.9 and 100%, respectively. The shell vial detected 66.3% of the positive cultures within 2 days of inoculation while the first posit...

Between days 10 and 21 after inoculation of Lupinus angustifolius seedlings with Rhizobium NZP 2257, the average nodule fresh weight increased 3-fold and the number of bacteroids per nodule increased more than 10-fold.The viability of Rhizobium bacteroids, as judged by their ability to form colonies on yeast-extract agar, declined from about 10% on days 10 and 11 after inoculation to about 0.3%...

We have studied the effect of natural and recombinant human interferons (HuIFN-alpha, -beta, and -gamma), and interleukin 1 (IL-1) on development of sporozoites of Plasmodium falciparum in cultures of functional hepatocytes. HuIFN-gamma inhibits hepatic schizogony of P. falciparum at very low concentrations (0.1 to 10 international units/ml), the target being the hepatocyte. Application after s...

The pathogenesis of experimental vaccinia virus infection in weanling mice after intracerebral inoculation was followed with virological, histological, and immunohistological methods. High-dose inoculation, virus spread from brain to thoracic and abdominal viscera probably by an undetected early viremia. Virus did rise to detectable levels in blood by day 5 and was found to be associated with t...

Methods Fifty four Balb/C mice of 7 to 10 weeks old under influence of estrogen were inoculated with 5x10 stationaryphase blastoconidia of C. albicans, intravaginally. The mice were divided in three groups, treated with glucan vaginally (5mg/mL) and intraperitoneally (1mg/mL), and the control group that received saline, intraperitoneally. Vaginal lavage was obtained on days 2, 5, 8 e 10 after i...

BACKGROUND Mycobacterium species are grown using specific media that increase laboratory cost, thus hampering their diffusion in resource-limited countries. Preliminary data suggested that versatile blood agar may be also used for mycobacterial culture. METHODOLOGY We examined the growth of 41 different Mycobacterium species on 5% blood agar. Over a 24-month period we analysed isolation of my...

Knowledge about porcine respiratory coronavirus (PRCV) tropism was limited to morphological identification of target cells and controversial reports on replication in macrophages. This study aimed to clarify the lung cell tropism of a Belgian PRCV strain and to examine the lung profile of inflammatory cytokines for 15 days after intratracheal PRCV inoculation of gnotobiotic piglets. Until 5 day...
