The Role of the Phagocyte in Host-parasite Interactions. I. the Phagocytic Capabilities of Leukocytes from Lymphoproliferative Disorders.

Isolation and Purification of the Schizont Stage of Theileria annulata from Host Leukocytes through Novel Biochemical Techniques

The intracellular protozoan parasite, Theileria annulata, induces uncontrolled proliferation and transformation in bovine B lymphocytes and monocytes in blood circulation andlymph nodes of host cells. This uncontrolled replication happens in the macroschizont stage of the life cycle of the parasites. The development of a rapid and efficient technique is likely to necessita...

Human T Lymphotropic Virus Type I (HTLV-I) Oncogenesis: Molecular Aspects of Virus and Host Interactions in Pathogenesis of Adult T cell Leukemia/Lymphoma (ATL)

    The study of tumor viruses paves the way for understanding the mechanisms of virus pathogenesis, including those involved in establishing infection and dissemination in the host tumor affecting immune-compromised patients. The processes ranging from viral infection to progressing malignancy are slow and usually insufficient for establishment of transformed cells that develop cancer in only ...

Role of neutrophils in protection of udder from infection in high yielding dairy cows

Protection of the mammary gland against mastitis-causing pathogens is mediated by many factors in thegland and blood circulation. The professional phagocytic cells of bovine udder, polymorphonuclearneutrophils (PMN) and macrophages, comprise the first line of defense against invading mastitis pathogens.Most researchers now accept that the PMN is a key factor in the cows’ defense against intrama...

Actinomyces bovis a possible cause for calcification of the parasite in the host tissue

Development of anti-malaria herbal preparation / drugs from local medicinal plants

1. The screening for potential anti-malaria properties by bioassay guided fractionations. The biological properties were carried out using the plasmodium lactate dehydrogenase assay (pLDH) (Makler, 1993). 2. The harmful effect of the extract was determined by the MTT assay (Mossman, 1983). 3. The extracts were tested for its efficacy in animal model using rodent malaria parasite, P. berghei usi...
