Twenty five freeze-dried isolates of Ornithobacterium rhinotracheale were used for the determination of minimum inhibitory concentrations (MIC) against the antibiotic fosfomycin (Fosbac, produced by Bedson SA, consisting of a 25% mixture of fosfomycin). The same isolates were tested for their ability to haemagglutinate chicken red blood cells. Ten of the 25 isolates were found to be susceptible...

the immunosuppressive effect of antimacrophage serum (ams) on the primary immune response of mice to sheep red blood cells (srbc) was studied. ams, given before a small dose of antigen, abrogated the immune response. transplantation of normal, galss-adherent macrophages enabled ams-treated animals to respond to srbc, while administration of lymph node lymphocytes did not reveres ams - induced i...

this article reviews will focus on the concept and formation of micro particles (mps) in circulation and their role in transfusion medicine and immune system. mps are cell membrane derived vesicles which express markers of their parent cells and are found in circulation at low levels. exact functions of mps are unclear. in here, physiological almost all types of circulating mps including platel...

A antigens of red blood cells and body fluids such as saliva, semen and sweat could be serologically distinguished using rabbit or guinea pig immune anti-A. As for antisera specific for red blood cell A, A+ rabbits were intravenously immunized with A group red blood cells. The resulting antisera were absorbed with O and B red cells and with A. Se saliva. The absorbed anti-A reacted with A red c...

A study on hemagglutination and hemolysis by Escherichia coli O111 and O55 (rabbit) antisera and on hemagglutination and hemolysis inhibition by E. coli O111 and O55 antigens revealed the following facts. 1. Red blood cells of man, dog, rabbit, guinea pig, sheep, rat, and chicken adsorb E. coli O111 and O55 antigens and thus become specifically agglutinable by the homologous E. coli antisera. 2...

Background: Falciparum malaria is a severe health burden worldwide. Antigen presenting cells are reported to be affected by erythrocytic stage of the parasite. Malarial hemozoin (HZ), a metabolite of malaria parasite, has adjuvant properties and may play a role in the induction of immune response against the parasite. Objective: To determine the immunological impact of hemozoin on the capacity ...

background: asphyxia is a common cause of perinatal mortality in 5-10% of all births worldwide. the present parameters for determining perinatal asphyxia, e.g. preeclampsia, cannot be considered as markers per se, and require auxiliary markers, e.g. increased number of nucleated red blood (nrbc) cells, for early diagnosis of perinatal asphyxia. objective: in this study, we evaluated the mean nr...

Malaria is a parasitic disease that causes severe hemolytic anemia in Plasmodium-infected hosts, which results in the release and accumulation of oxidized heme (hemin). Although hemin impairs the establishment of Plasmodium immunity in vitro and in vivo, mice preconditioned with hemin develop lower parasitemia when challenged with Plasmodium chabaudi adami blood stage parasites. In order to und...
