studies have shown that aflatoxin is immunosuppressive and its ingestion in feed has resulted in decreased immunity in vaccinated birds .therefore, the purpose of the present study was to determine the efficacy of sodium bentonite (sb) and esterified glucomannan (e-gm) of yeast cell wall, in counteracting the toxic effects of aflatoxin (af) on immunization against infectious bursal disease (ibd...

The cytotoxicity of various ball-milled UICC amosite samples toward mouse peritoneal macrophages in vitro was examined. On increased ball milling, the cytotoxicity of the amosite samples fell. This decreased biological activity seemed to correlate best with number of fibers longer than 4 micron/micrograms dust, rather than total number of fibers or the electrophoretic mobility of the amosite sa...

This chapter describes the state of technology for studying Internet crimes against children, specifically and . We begin by presenting a survey of relevant research articles that are related to the study of . This survey includes a discussion of our work on the classification of chat logs that contain or . Many commercial enterprises have developed to monitor these behaviors, and the latest ve...

background: renal ischemia reperfusion injury may occur in a variety of clinical situations, following a transient drop in total or regional blood flow to the kidney. this study was performed to investigate the protective effects of different antioxidants such as vitamin c, vitamin e, hydrocortisone and combination of these agents against experimental renal ischemia-reperfusion injury. method:...

conclusions our results showed that broad-spectrum antibiotics such as imipenem, meropenem, fosfomycin, cefoperazone/sulbactam, and vancomycin would be the first line and the most effective drugs for the empirical treatment of urinary tract pathogens due to their higher resistance rates against other drugs like cephalexin, cephradine, ciprofloxacin, levofloxacin, and norfloxacin. patients and m...

background:the bacterial contamination of fertile eggs isthe most common cause of embryonic death in ostrich hatcheryunits leading to financial loss in ostrich industry. objectives:the aim of this research was to investigate the bacterialcontamination status, with emphasis on escherichia coli, ofostrich hatcheries and the antimicrobial resistance profile ofisolated escherichia coli. methods:ato...

Background and objectives: Echinophora platyloba is used for flavoring foods, cheese and yoghurt. Despite several pharmacological studies on the plant, no attempt has been made to isolate the non-volatile secondary metabolites and assess the antimicrobial effects. So, phytochemical investigation seems to be useful for better use of this plant. Methods: </strong...

abstract background: escherichia coli, known as a clinically significant bacteria, can cause a wide range of infections, including urinary tract infections (utis), blood stream infections (bsis), and can frequently be isolated from various clinical specimens. evaluation of antimicrobial resistant pattern is a necessary action, especially about such bacteria which are frequent and life threateni...

disk diffusion test is the usual applicable method for assessing the antimicrobial susceptibility pattern in most institutions and hospitals. the aim of this study was to determine the reliability of resistant-reported results of disk diffusion test for 6 routinely used antibiotics against gram-positive microorganisms of nosocomial origin, using e-test method.    over a 1-year period, clinical ...
