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 ...

TORYMUS SINENSIS: BIOLOGY, HOST RANGE AND HYBRIDIZATION

Acta Horticulturae, 2014
Torymus sinensis is a solitary ectophagous parasitoid of the chestnut gallwasp, Dryocosmus kuriphilus. It originates, like its host, from China. Following the accidental introduction and rapid range expansion of the pest in Japan (in the 40s),USA (70s) and Italy (2000s), T.

The Biology of Hookworms in Their Hosts

The Quarterly Review of Biology, 1930
D U URING the last quarter of a century a great deal of attention has been given to the group of parasites known as the hookworms, which infest man and certain animals. The chief reason for this attention has been the importance of these parasites in the field of public health, but out of the work have come many observations which are of interest from ...

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 ...

Lactobacilli biology, applications and host interactions

Nature Reviews Microbiology
Lactobacilli encompass more than 300 species, spanning 25 genera, found in the microbiomes of humans, animals and plants with relevance in agriculture, foods and medicine. Lactobacilli comprise all bacteria previously assigned to the Lactobacillus genus and, similar to other lactic acid bacteria, are characterized by their saccharolytic, fermentation ...

EFFECTS OF HOST SOCIALITY ON ECTOPARASITE POPULATION BIOLOGY

Journal of Parasitology, 2004
Theory predicts a positive relationship between parasite infection intensity and host density. However, this generalization is complicated in natural systems by differences in life history among parasite taxa, e.g., transmissibility. Accordingly, predictions relating host density to parasite load should be specific to each parasite taxon. To illustrate

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

Complement and Bacteria: Chemistry and Biology in Host Defense

Annual Review of Immunology, 1984
an enormous expansion in our understanding of the details of complement biochemistry and in our appreciation of the role of complement proteins in biologic phenomena. In this review we explore one important aspect of complement function-the role of complement in host defense against bacterial infection.

Parasite Biology: The Reservoir Hosts

2018
Leishmaniases are worldwide vector-borne diseases with diverse clinical manifestations caused by protozoa belonging to genus Leishmania. About 20 named Leishmania species are pathogenic for humans and are annually responsible for 0.7–1.2 million cases of cutaneous and 0.2–0.4 million cases of visceral forms of the disease. According to the transmission
