background: based on recent studies, there are controversial reports on the ca-pacity of tissue cyst forming of toxoplasma gondii rh strain. in this study, the capac-ity was evaluated by in vivo and in vitro experiments. methods : rh strain was subcutaneously inoculated to ten wistar rats. after one month, their blood, brain, tongue and diaphragm were collected and evaluated by mat, pcr, pathol...

this study was conducted to determine the chemical composition, digestibility, degradability and nutritive value of madder, rubia tinctorum l.  and alfalfa medicago sativa. using in vitro and in situ measurements. the mean values for om, cp, ndf, adf and ee were 892.5, 172.0, 306.5, 219.4 and 16.0 g/kg dm for madder hay, and 921.3, 141.4, 482.0, 361.1 and 6.50 g/kg dm for alfalfa hay, respectiv...

background: based on literature, in vitro cholesterol removal of lactic acid bacteria has been accounted for their in vivo cholesterol reduction. but recently, it has been proposed that such in vitro characteristic may not be directly relevant to their in vivo activity. the objective of this study was to find how much in vitro cholesterol reducing potential of lactobacillus plantarum a7 (la7), ...

Alternatively activated macrophages (aaMphi) display molecular and biological characteristics that differ from those of classically activated macrophages (caMphi). Recently, we described an experimental model of murine trypanosomosis in which the early stage of infection of mice with a Trypanosoma brucei brucei variant is characterized by the development of caMphi, whereas in the late and chron...

By a suppression subtractive hybridization based method, nine novel Mycobacterium avium subsp. paratuberculosis (M. paratuberculosis) fragments of between 318 and 596 bp have been identified and characterized. Database search revealed little or no similarity with other mycobacteria. The uniqueness and diagnostic potential of seven of these fragments in relation to M. paratuberculosis closest re...
