West Nile virus (WNV) is transmitted to vertebrate hosts by mosquitoes as they take a blood meal. The amount of WNV inoculated by mosquitoes as they feed on a live host is not known. Previous estimates of the amount of WNV inoculated by mosquitoes (10(1.2)-10(4.3) PFU) were based on in vitro assays that do not allow mosquitoes to probe or feed naturally. Here, we developed an in vivo assay to d...
BACKGROUND Respiratory co-infections are important factor affecting the profitability of pigs production. Swine influenza virus (SIV) may predispose to secondary infection. Haemophilus parasuis (Hps) can be a primary pathogen or be associated with other pathogens such as SIV. To date, little is known about the effect of coinfection with SIV and Hps on the disease severity and inflammatory respo...
To determine the susceptibility of rabbits to experimental infection with human T-cell lymphotropic virus type-II (HTLV-II), four separate groups of four weanling rabbits each were inoculated intravenously with lethally irradiated HTLV-II-infected human cell lines Mo-T (HTLV-IIMo-infected T cells), WIL-NRA (an Epstein-Barr virus [EBV]-transformed B-lymphoblastoid cell line infected with HTLV-II...
The objective of this study was to determine the effects of a homolactic acid inoculant on ensiling characteristics and nutritive value of high dry matter (DM) alfalfa. The ensiling characteristics were determined by ensiling inoculated and untreated alfalfa haylage in mini-silos for 0, 2, 4, 8, 16 and 45 days. Two lactating cows fitted with ruminal fistulas were used to determine ruminal degra...
to survey the effects of flooding during the reproductive growth stages of aerenchyma formation and ethylene production in soybean cultivar dpx experiment the completely randomized factorial was in 2012 in gorgan university of agricultural sciences and natural resources. factors examined include nutrition levels in three levels (1 - inoculated with bacteria japonicumbradyrhizobium 2 - non-inoc...
salinity is one of the major problems in the world's vast areas of land are also faced with this problem. endophytes are microorganisms that use of the soil microorganisms, the reduction of environmental stresses such as salinity, has become a global solution. therefore, to investigate the effects of inoculation of fungal endophytes piriformospora indica and bacteria symbiosis hay azospiri...
The consumption of Toxoplasma gondii oocysts on fresh produce may be a means of its transmission to humans. Cats shed T. gondii oocysts, which contaminate produce directly or contaminate water sources for agricultural irrigation and pesticide and fertilizer applications. Cyclospora cayetanensis is a related coccidial parasite, and outbreaks of diarrhea caused by C. cayetanensis have been associ...
