Malaria: Host-Pathogen Biology

Clinical Infectious Diseases, 1982
The development of resistance to insecticides by anopheline mosquito vectors of malaria and of resistance to drugs by Plasmodium falciparum pose new challenges for malaria control programs. The establishment of methods for the continuous cultivation in vitro of plasmodia provided an important new tool for research into the cellular biology and ...

Giardiasis: Host-Pathogen Biology

Clinical Infectious Diseases, 1982
Giardiasis is the most common waterborne diarrheal disease in the United States and is highly prevalent throughout the world. The clinical spectrum of disease ranges from asymptomatic infection to persistent severe malabsorption. The precise interaction between Giardia and its human host remains conjectural because of the paucity of published studies ...

Schistosomiasis: Host-Pathogen Biology

Clinical Infectious Diseases, 1982
Schistosomes are helminths of the class Trematoda that alternate generations, with a sexual phase in definitive mammalian hosts and an asexual phase in intermediate snail hosts. In humans, these blood flukes reside in the mesenteric and vesical venules. They have a life span of many years and daily produce large numbers of eggs, which must traverse the

Biology and Host Relationships

1967
It is well known that aphidiids are all primary, solitary, internal parasites of aphids. Many excellent papers on biology, ecology and host relationships of the Aphidiidae have appeared within the past few years, and even though it is not our intent to review or discuss these subjects to any great degree, it seems important to mention some of them, as ...

Amebiasis: Host-Pathogen Biology

Clinical Infectious Diseases, 1982
Invasive amebiasis caused by Entamoeba histolytica, and particularly amebic liver abscess, is a major public health problem in Mexico and some other countries because of the high incidence and mortality of this disease. This paper first discusses the pathogenic effect of E.

Hookworm Disease: Host-Pathogen Biology

Clinical Infectious Diseases, 1982
The hallmark of hookworm infection, a common helminthic disease, is iron deficiency anemia. The development of anemia is dependent on the intensity of infection, the species of hookworm, and the ability of the host to resist infection and to maintain adequate stores of iron. When conditions are appropriate, the incidence of anemia caused by hookworm is

Biology of host-macroparasite associations

1991
Abstract Many important diseases of humans, particularly in tropical and subtropical regions, arise from infection by macroparasites or metazoan (multicellular) organisms. The major parasites belong to the helminth and arthropod groups, and include flukes (the trematodes), tapeworms (the cestodes), nematodes, lice, fleas, and ticks ...

The Biology of Viroid-Host Interactions

Annual Review of Phytopathology, 2009
Viroids are single-stranded, circular, and noncoding RNAs that infect plants. They replicate in the nucleus or chloroplast and then traffic cell-to-cell through plasmodesmata and long distance through the phloem to establish systemic infection. They also cause diseases in certain hosts.

Biology of Graft-vs.-Host Disease

Journal of Pediatric Hematology/Oncology, 1993
Graft-vs.-host disease (GVHD) is a major complication of allogeneic bone marrow transplantation, which is an important approach for the treatment of various diseases. In experimental animal models, lethal GVHD can be induced in major histocompatibility complex (MHC)-matched strain combinations that differ in their expression of multiple minor ...

Biology of Cryptosporidium from marsupial hosts

Experimental Parasitology, 2010
The majority of biological data on Cryptosporidium has been collected from humans and domestic animal hosts which creates a bias in knowledge on the biodiversity and evolution of this parasite genus. Further to understanding Cryptosporidium biology are studies encompassing broad hosts that represent diverse taxa sampled across wide geographic ranges ...
